ALFRED MDGE & SON, PRNTERS, 24 FRANKLN STREET, BOSTON. go)~a HE Glee Club, from the tme ~<',, /~; ~5 when t was started, has been a credt to the nsttute, and should receve the most hearty \,',~ / support from /,,~! X l.\,.lo;, le,,, all students, whether sngers or not. The club was organzed last fall, and after some rehearsng gave a complmentary concert to the school, whch was much apprecated by all who had the opportunty to hear t. Snce then, the club has sung n varous places n the vcnty, and was everywhere receved wth favor. We are now to have another chance of hearng them at home. A concert wll shortly be gven n Assocaton Hall, for whch the tckets are now ready. Reserved seats can be procured from the muscal drector, and admsson tckets from other members of the club. The prce of tckets has been placed so low that t s wthn the reach of all, and we hope that all wll aval themselves of ths prvlege of hearng a good concert and helpng support a worthy organzaton. The club s at consderable expense n procurng new musc and other necessary thngs, and a good attendance at the next concert wll do much to strengthen ts fnancal condton. Let every student go to the concert, and gve the club a good recepton at home. A T the present tme the country s excted by reports of gold found n enormous quanttes at the Coeur d'alenes, n daho, and as a consequence there has been an mmedate rush of seekers for gold to that regon. No authentc nformaton has yet been receved as to the extent or rchness of the placer dggngs; but that gold exsts there along the streams s unquestonable. The Eastern magnaton s apt to be taken wth reports of yelds of twelve to twenty dollars a day to each man; of wages, to any one who wll work, of from fve to eght dollars per day; of the reported aggregate of 8,ooo worth of dust taken from one clam, the "Wdow," and at once thnks t the place to go to, wthout duly weghng the other sde of the queston; the presence of a multtude already there, most of them old mners, who, perhaps, cut ther wsdom teeth n Calforna, and besde whom one's chances for ganng experence would be vast, but hs chances of gettng gold at ther mnmum. The cost of the bare necesstes of lvng s enormous, and f one desred to make money hs wser way would be to go out there as a seller of "eggs, bacon, and boots," whch command a premum. The gold fever of '49 s beyond the memory of most of our mners, to whom ths s especally addressed; but the recollecton of personal experences told to the wrter cones vvdly to mnd. One hears more often, n cases of great dscoveres of gold, of rch fndngs n specal nstance; but of the thousands who are unsuc-

4 r 164 cessful whose lves are runed by the absence. of any sort of restrant, and the prevalence of the worst features of men's characters, of the msery brought upon the mothers and famles left behnd, we hear only by accdent, or n the hstory of after years. A few weeks wll do much to solve the problem, and gold wll be plentful, or the localty be voted a falure; n the latter case, an undeserved odum wll reman wth the place. Of the crowds whch have flocked thther, many wll never come East agan: attracted by the easy lfe n the West, they cut ther moorngs and start, probably, upon a lfe of adventure. T s wth regret that we are oblged to note the recent dsturbances n the chemcal laboratory among the second-year mners and chemsts, whch resulted n the suspenson of some of ther members. The course of Prof. Wng n callng a class meetng at whch the members were free to express ther' opnons n regard to the matter, and leavng the remedy to ther good judgment and honor, s one whch must meet wth the heartest commendaton, and whch we hope wll be adopted by our other professors f any trouble happens to arse n ther classes. FOR the beneft of those nterested, t may be stated that exchanges are placed n bnders shortly after ther recept, and as a rule only the la' est two numbers are kept there. Earler ssues for ths year may be obtaned n THE TECH bookcase. t s desrable that any of these taken out be returned to ther proper places, otherwse ths use of them may be dscontnued. N an edtoral n the last TEC, n regard to the cost of underground wres. we were made to say that "the cost... would be.... for the cables, about $50 per mle; so that, n round numbers, we may say that one thousand mles would cost $ 50,000 per mle, or $ X 5o a mle for each crcut." The correct statement s that, n round numbers, the cost would be about $150,- ooo per mle for one thousand wres, or $ 150 per mle for each crcut. Papyrographs.

A PAPER READ BEFORE THE 2 G SOCETY. THERE s an mpresson among the majorty of people that Scence s somethng dark, deep, hdden, and abstruse. n fact, many beleve that the very word scence ndcates somethng unfathomable, somethng that cannot be comprehended by ordnary people. Some beleve that scence s alled to alchemy, astrology, or wtchcraft, and that knowledge of t s to be shunned as one would shun the plague or other loathsome dsease. Some beleve that t s synonymous wth athesm, nfdelty, and godlessness. But t s none of these. One of the brghtest scentfc lghts of the nneteenth century has gven one of the most expresswve defntons of scence that could be gven. He says, "Scence, beleve, s nothng but traned and organzed common-sense." t s of the natural scences that we wsh to speak to nght. Natural scence s the knowledge of the laws governng the forces of nature. Nature s a term employed to sgnfy all the bodes of the unverse collectvely. These bodes, organc andnorganc, are subject to a varety of changes. The agents or causes of these changes may be ether nternal or external to the bodes. t s the object of natural scence to nvestgate nature wth reference to these changes and ther causes. E =

5 - 165 '"All the phenomena of the physcal world arse drectly from the acton of forces upon the varous forms of bodes." t s the provnce of natural scence to nqure nto these phenomena, and, f possble, to formulate the laws whch govern both the causes and effects. For ts data n reference to these causes and effects, scence reles upon observaton and experment. By observaton we note any changes that take place n the condtons or relatons of any body or ts elements, as they spontaneously arse wthout any nterference on our'part; whereas, n the performance of an experment, we purposely alter the natural arrangement of thngs to produce the result that we desre. Thus, f we notce that n wnter water becomes converted nto ce, we are sad to make an observaton; f, by the use of freezng mxtures or rapd evaporaton we produce ce from water, we are then sad to perform an experment. Smlarly, f we balance a compass-needle upon the sharp pont of a fxed vertcal rod, and note that the marked end always ponts towards the north, we have made an observaton. But f we balance a small steel bar upon the pvot, and fnd that t stands n any poston n whch we place t, and then remove t, magnetze t, and, upon replacng t, fnd that t rotates untl the marked end ndcates the north pont, as n the frst case, we are sad to have made a seres of observatons, performed an experment, and then made a fnal observaton whch confrmed our hypothess that the bar would algn tself n a north and south lne after magnetzaton. These observatons and experments are next subjected to mathematcal analyss and calculaton, from whch are deduced what are known as "the laws of nature," or "the rules that lke causes wll nvarably produce lke results." Where possble, these laws, for the sake of brevty, are expressed by mathematcal formule. When, however, these laws are not determned wth suffcent exactness to admt of ther beng expressed wth mathematcal precson, we must be content wth nferences and assumptons based upon analoges, or wth probable hypotheses for explanaton and deducton. "An hypothess gans n probablty the more nearly t accords wth the ordnary course of nature, the more numerous the observatons and experments on whch t s founded, and the more smple the explanaton t offers of the phenomena for whch t s ntended to account." f the number and range of these observatons be suffcently great, and the explanaton of the observed phenomena be logcal and reasonable, the hypothess may attan to the dgnty of a "thelocy." f no exceptons can be detected or dscovered n the phenomena whch attend the acton of certan forces, and the scentst s enabled to predct wth certanty the logcal sequence of events whch wll take place due to the acton of these forces together wth all the attendant phenomena drectly dependent upon sad acton, then the theory s enttled to be removed from the realm of probablty and to be recorded as one of the laws of nature. The feld of observaton s ndeed a large one. For convenence, shall dvde t nto three heads, conscous, however, that the lnes of demarcaton are so convoluted and nterlocked that they must be but arbtrary at best. Actual observaton may be () telescopc, (2) macroscopc, or (3) mcroscopc. (.) Telescopc observaton enables us to penetrate the depths of space n search of truth, to explore mysteres whch but for ts nterventon would have remaned locked n the bosom of space unknown and unseen by the eye of man. Who shall estmate the value of the telescope to scence? To adequately chroncle ts dscoveres, ther number, mportance, and value would requre volumes. Let t suffce to drect attenton to a few of ts best known results. t was to the use of the crude and mperfect nstrument of Galleo that we owe the dscovery of the sun spots, the mountans n the moon, and the exstence of Jupter's satelltes. From

6 r P e s 5 L 166 T1HE ths humble begnnng astronomcal scence has slowly but surely advanced, untl now her nstruments of precson have reached a hgh degree of excellence. To these advances we owe the dscovery of the nebulae, those nascent worlds of dssocated star-dust, whose atoms are whrlng through ther molecular orbts n obedence to the unversal law of gravtaton. To telescopes we owe the dscovery of the magnfcent group of rngs and satelltes that accompany the planet Saturn n hs orbt around the sun. The same nstrument detected the planets Neptune and ranus wth ther fant satelltes, together wth the numerous mnor planets. To t we are ndebted for the dscovery of double, trple, and multple stars. Many double stars exhbt the curous and beautful phenomenon of complementary colors. n these nstances "the large star s usually of a ruddy or orange hue, and the smaller one of blue or green." Ths may be but the effect of contrast, but there s no reason to doubt that n many cases color exsts. The latest great dscovery made by astronomcal scence was that of the dmnutve moons of the planet Mars, that near physcal relatve of our earth. These nterestng objects were made known to the nqurng gaze of man through the medum of the great equatoral refractor at Washngton. Thus have we glanced at a few of the results of telescopc observaton. Thus, through the evoluton and development of ths potent nstrument for fathomng, feebly t s true, the depths of nter-stellar space, have we succeeded n wrestng from that boundless nfnty many thngs whch but for t would stll be enshrouded by an unpenetrated vel. Thus, n less than three centures, have we passed from the mperfect and nsgnfcant glass of the talan astronomer to the magnfcent refractor at Washngton, whose defnton and space-penetratng power exceeds even the wldest dreams of the seventeenth-century phlosophers. May we not congratulate ourselves that ths TEC}H. _ trumph of mechancal art, ths crownng glory of astronomcal and optcal scence, was made upon the sacred sol of the Commonwealth of Massachusetts? (2.) Macroscopc observaton comprehends all observatons of the outward or vsble world made by the human eye. t s the means by whch a knowledge of the objects surroundng us s obtaned. t s the most general knd of observaton wth whch we are acquanted. t s a term borrowed from the scence of petrography, and s here used to comprse all vsual observatons that are not ether telescopc or mcroscopc. t s essentally the observaton most used n our every-day lfe. t enables us to see and enjoy our frends, our homes, our landscapes, and our skes. Ths method s employed by the nfant and the patrarch, the plough boy and the phlosopher, the gnorant and the enlghtened, the untutored savage and the cultured denzen of the metropols. t was n use untold centures before the nventon of ether telescopes or mcroscopes. Through t many of the phenomena of the organc and physcal worlds have been brought to the notce of the mnd of man, wthout, however, elctng ratonal, or, n many nstances, even ntellgble nterpretatons. By t wve dstngush the dfference between an anmal and a plant, between a rock and an apple, between daylght and darkness, between the lghtnng's flash and the gleam of a candle. (To be contnued.)

[ The Edtors do not hold themselves responsble for opnons expresed by corres5zondents.] To THE EDTOR OF THE TECH: - n a recent number of THE TECH appeared an artcle advocatng the extenson of the course at the nsttute to sx years. Whle concdng wth the sentments nsprng ths artcle, the wrter wshes to dsagree wth ths proposal. The work done at the nsttute s too severe. For a student pursung hs studes fathfully, the mental stran approaches, perhaps exceeds, the ntellectual elastc lmt. To reduce the hgh standard of resultant excellence s a remedy whch wll fnd no favor among the alumn, although to many a mnd a long step n ths drecton was taken when Prof. Howson severed connecton wth the school. Of the more recent changes n the engneerng departments, t s a pleasure to say that they meet the approval of the large majorty of the graduates. t s an easy soluton of the dffculty to say the course should be extended; but we must consder that ths step wll necessarly ncrease, almost proportonately, the expense to be ncurred by the student. nfortunately, to a great number of the patrons of the nsttute, the annual budget s an element nsprng most rgd calculaton, and an ncrease of twenty-fve per cent n the outlay would cause the relnqushment of the scheme of educaton by a class of persons among whom wll always be. found the best students of the nsttute. The scheme whch the wrter would propose s that whch has always been the dea of the corporaton, to exalt the requrements necessary for admttance. Ten years ago, - and the condtons have changed lttle snce, -a boy of ffteen who had fathfully pursued hs studes n the publc schools and who had only partally completed hs hgh-school course, was ftted,- we wll not say for the nsttute,- but to pass ts entrance examnatons and could have studed for three years Latn or Greek. How soon the same boy could have been ftted by the narrow and mstaken method of preparatory schools the wrter does not venture to estmate; but he wll assert,- and n the opnon s sustaned by every graduate wth whom he ever conversed, - that no boy at the age of ffteen or sxteen s ftted physcally or ntellectually for that phlosophcal, mathematcal, magnatve, and speculatve hothouse known as the nsttute of Technology. The studes at the nsttute should begn where our publc free schools stop. These schools, t s true, g've as a rule only a superfcal knowledge of the many subjects they pretend to teach, but every student knows that the most elementary knowledge of a subject taken up at the nsttute s the savng condton whch oftentmes determnes hs success. For ths reason the wrter would advocate an examnaton on German, trgonometry, physcs, astronomy, physology, zo6logy, botany, geology, chemstry, and physcal geography. Profcency n any seven of these mght make up for gnorance of the remander, as the extra knowledge possessed would allow some spare tme on one subject whch could be devoted to those n whch a defcency exsted. t s almost a safe asserton to make that, of those graduatng from the nsttute wth a credtable record, eghty per cent come to the school possessng the knowledge embraced n the above specfcatons, and that ths knowledge was an mportant factor n ther success. f e Z 9 J R Ja m R

9 - 169 ths s true, the admttance examnatons to the nsttute may be styled a system of false pretence, entcngb to the school numbers of persons who cannot succeed unless by neglectng all rules of physcal and mental hygene. n addton to these qualfcatons, a better knowledge of French mght be requred, and an acquantance wth Latn or Greek, whle not perhaps to be nssted upon, mght be placed to the credt of the applcant. WVth these requrements, and the mnmum age placed at seventeen, t s to be hoped that as hgh a grade would be reached and less fall by the waysde. Prmary-school educaton at the nsttute would cease and the "Kndergarten" be no more. f any are n doubt as to the bearng of ths last observaton, let them reflect upon the followng tem of hstory: - Prof. (to Sophmnore class): "Gentlemen, ths colored map before you s known as Guyot's map. The mountans are colored a dark brown, the tops beng touched wth whte to represent snow. The lower levels are colored a lghter brown and the lowest lands of all around the coast and elsewhere are tnted green. "Ths part to whch pont, gentlemen, s green. s ths hgh or low land? Let t be sad n smple justce to the memory of the class of '79 that wth one accord they answered " hgh!" t seems as f t could be n ths way only that the school can keep that proud poston whclh t has occuped n the past and whch t should always strve to surpass. H. H. C. Steelton, Pa., March 23, S84. At Prnceton, there has been great exctement over a fancful system of esponage, supposed to have been undertaken by the college authortes. The matter as stated n the college lmerczuy s thus: " At Prnceton, there has also been great exctement, and, though the results to ndvduals s not as dsastrous, the harm to the collge s almost as serous. One mornng the students found a letter n ther post-offce boxes callng ther attenton to the methods employed by the Faculty n dscplnng those whom they governed. A mass meetng was held and many serous charges were made aganst the dean of the Faculty and aganst a certan professor. A system of esponage, t was clamed, was employed. Many men weepngly asserted that ther poker decks had been stolen from them, that brakemen on the Trenton trans had been questoned on many ponts, and that the town barber had turned college nformer. As befts mass meetng, resolutons were drawn up and a commttee of nvestgaton apponted. Everythng was prepared for a genune sensaton, when the student who had made the most serous accusaton 'crawled' (as the Prnceton man would say), the owners of the poker decks sad that they mght be n error as to the dsappearance of the same, and every one else acknowledged the possblty of hs beng mstaken." PHOSPHORESCENCE N LMESTONES. -A good example of phosphorescence n lmestone was seen recently n a specmen from tah, whch emtted a lurd red lght when struck, scratched, or heated. The glow lasted from half a second, when lghtly struck, to a much longer tme, as the result of a blow. The specmen, on examnaton, proved to be almost perfectly pure carbonate of lme wth very slght percentage of mpurtes. t was loose graned, whte, and crystallne, the grans beng but slghtly coherent, and much resembled a soft sandstone. t crumbled easly between the fngers, formng a coarse sand. When heated n a glass tube over a flame, t glowed wth a deep red lght, whch lasted a mnute or more after wthdrawng the flame. After two or three heatngs the phosphorescent property dsappears. Correspondng effects were produced after examnaton of numerous specmens from a lmestone from nda, whch also resembled externally the tah stone. n each case the phenomena are probably due to a dsturbance of the loosely aggregated crystallne partcles, whether such be prodluced by percus,on, frcton, heat, or decreptaton.

Last week was a good example of New England weather. Mr. Davd Van Alstne, '86, has been elected a member of Sgma Ch. Several nsttute men are rehearsng wth the Wagner Festval Chorus. We are sometmes surprsed at the amount of muscal and th/eatrcal talent at the nsttute. Only fve weeks more before the annuals. Now s the tme to " grnd." The frst-year archtects are revellng n ther now problem of a temple-tomb. The 2 G Socety held ts regular meetng on Tuesday, the 8th, when mportant busness was transacted. Prof. Vose has been elected presdent of the Boston Socety of Cvl Engneers for the ensung year. The second-year cvls and mners have begun ther sprng feld work, levellng. We learn wth great regret that Mr. Herbert G. Pratt, '85, has been oblged to abandon hs studes and to go South for recreaton. A quartet of strnged nstruments wth pano accompanment s rehearsng for the next meetng of the Junor cla5s. Qute a large delegaton from the nsttute were present at the castng of the second large gun at the South Boston foundry. Presdent Walker s promnently mentoned as a delegate to the Republcan Natonal Conventon at Chcago. At our recent athletc games, Mr. P. R.

Photographs of the '86 tug-of-war team, whch defeated the Harvard Law School team at our last games, can be obtaned of Mr. Shove, '86. The bad weather of last week prevented the mners' and chemsts' excurson to Ftchburg and the bcycle club's run on Fast Day. The nsttute Chapter of Sgma Ch held ts annversary dnner at Young's on Frday, March 2 r. Thrteen members were present. The second-year mechancals recently spent an nterestng afternoon n examnng the looms of the weavng department of the School of Desgn. The certfcates of membershp for the 2 G Socety are nterestng lookng documents. The seal s about two nches n dameter, bears the front of the Rogers Buldng n relef on ts face, and was desgned ad executed by. W. Ltchfeld, '85, upon whom t reflects great credt. The motto at the base s the old German one of "Schlagel und Esen." The socety s n a prosperous condton and endeavors to afford substantal ad to the members n the study of mnng engneerng at the nsttute. The corps of cadets under Major Locke gave an exhbton drll n the gymnasum on Saturday, March 29. The battalon showed much mprovement, and executed the varous manceuvres of battalon and company drll n good shape. After the drll, the balance of the afternoon was spent n dancng. The students at the nsttute nterested n bcyclng held a meetng recently whch was largely attended. Consderable nterest was shown and a club was formed wth the followng organzaton: Presdent, Jas. C.

Steele, '86; an executve commttee, consstng of the presdent, secretary, captan, Messrs. Cochran, '85, and Steele, '87. The club promses to be a flourshng organzaton and a credt to the nsttute. Three mners were recently dropped from the mnng laboratory because of neglect to hand n tme cards. [P. S. "'Zwschen L6ffel und Mund, Geht vel Suppe zu Grund."

[We shall be glad f the author wll call at room 8 for hs MS. between 4.30 and 6 p. M ] Mr A. Stuart Pratt,formerly of '84, left Boston March 24, amd the tears and good wshes of hs frends, for the West. He s gong on a cattle ranch n Nebraska. The annual Senor Ball - wthout the Senors - was gven n Odd Fellows' Hall, Frday evenng, Aprl 4, by '85, '86, and '87, to '84. About seventy-fve couples were present, and the affar proved a brllant and thoroughly enjoyable one n all respects. t s to be regretted that so many of the Senors chose to hde ther gray heads elsewhere rather than show, at least by beng present, ther apprecaton of the complment tendered them. Mrs. John D. Runkle, Mrs. Webster Wells, and Mrs. Wllam T. Sedgwck kndly acted as matro. 1 s for the party. The floor commttee, to whom much credt for the complete success of the affar s due, conssted of T. W. Robnson, '84, F. G. Pratt, Everett Morss, and A. R. McKm, '85, Charles Wood, Theodore Stebbns, and S. R. Bartlett, '86, G. W. Davenport, A. L. Cushng, and H. C. Spauldng, '87. The orders, upon whch the nsttute seal fgured promnently, were desgned by Mr. Wood. J. Howard Rchardson's orchestra furnshed exceptonally good musc, and Harvey Blunt lad the table.

12 172 tepartment o.tes, V. Meyer has recently separated from benzne ols a composton, to whch he gves the name of Thophen. The composton of ths body s represented by the formula C 4 H 4 S ; t presents the closest analogy n general reactons wth benzne, yeldng a sulphonc acd, a methyl dervatve, etc.; t reacts wth dketones to form hghly colored compounds. The further study of ths nterestng compound, now beng carred on n Prof. Meyer's laboratory, s lkely to lead to mportant results. (Berchte, xv., 2968.) Mr. John L. Wllams, a mne nspector of the Readng Coal and ron Company, has nvented an mprovement on the Davy SafetyLamp for mners by whch the lamp can be quckly extngushed by means of a wck cover worked from the nteror. When a body of gas suddenly makes ts presence known, a falure to be able to extngush the lght quckly brngs wth t an exploson. As the mners wll remember, the only means of reducng the flame n an ordnary Davy lamp s by means of a "prcker" worked from the outsde. We recommend to the mners an nterestng artcle n the Efngncerg and lnncg youlrhal for March 15 on the Durango ron Mountan n Mexco. Some analyses of the ore show t to be remarkably rch, - the crude ore contanng about eghty per cent of ferrc and magnetc oxdes, three per cent phosphorus, and only a fracton of one per cent of ttanc acd. The Western non Telegraph Company (bya recent report) had, n 883, 428,546 mles of wre strung upon 143,452 mles of poles, spread over ths country n all drectons, and these fgures are constantly ncreasng. t s rumored that the New York and New England Ralroad ntend puttng on a fve-hour tran to New York, as soon as the double track s completed, whch wll be n the course of a few months. The dstance to New York va the Ar Lne s only 215 mles, or 19 mles shorter than the Sprngfeld route, and about 14 mles less than by the Shore Lne. A track tank s beng constructed near Putnam, so that engnes may - pck up water whle runnng; and t s sad that rans wll be run from Boston to Wllmantc, the Ar Lne juncton, a dstance of 86 mles, wthout a stop. From a knowledge of the New York and New England road and ts grades, whch n places are sxty feet to the mle, we doubt the feasblty of the fve-hour tran, as t would necesstate a speed of about 47 mles an hour over the man porton, allowng a much slower speed over the heavy grades of the Ar Lne. Were t not for the numerous drawbrdges at whch the Connectcut law requres stops, a very hgh speed mght be obtaned over the New York, New Haven and Hartford Road, whch s comparatvely level. t s sad that the New York and New England n double trackng wll mprove ts grades somewhat.

The frst class graduated n The school s devoted to the teachng of scence as appled to the varous engneerng professons: vz., cvl, mechancal, and mnng engneerng, as well as to archtecture, chemstry, and natural hstory, physcs and electrcal engneerng, and metallurgy. Besdes the above dstnctly professonal courses, the nsttute offers scentfc courses of a less techncal character, desgned to gve students a preparaton for busness callngs. A four-years' course n bology, chemstry, and physcs has been establshed, as preparatory to the professonal study of medcne. Modern languages are taught so far as s needed for the ready and accurate readng of scelntfc works and perodcals, and may be further pursued as a means of general tranng. The consttutonal and poltcal hstory of England an l the nted States, poltcal economy, and nternatonal law are taught, n a measure, to the students of all regular courses. Applcants for admsson to the nsttute are exanmned n Englsh grammar, geography, French, arthmnetc, algebra, and geomletry. A fuller statement of the requrements for admsson wll be found n the catalogue, whch wll be sent wthout charge on applcaton. A clear admsson paper from any college of recognzed character wll be accepted as evdence of preparaton, n place of an examnaton. Graduates of colleges con'errng degrees are presumed to have the necessary qualfcatons for enterng tlhe thlrd-year class n any of the regular courses of the nsttute, and wll be so admtted provsonully, on the presentaton of ther dplolmas. The feature of nstructbn whch has been most largely developed n the school s laboratory tranng, shop-work and feld practce, to supplement, to llustrate, and to emphasze the nstructon of the rectaton and lecture room. Surveyng nstruments are provded for feld work n cvl and topographcal engneerng.
