For a mnng socety gotten up and mostly composed of Junors to solct recruts, and then compel them to pass through such a performnance, seems rather out of place for the nsttute. We were, however, hghly gratfed to see that two students had the self-respect and courage to wthdraw from a contnuance of the ntaton. How the wearng of a shoestrng about one's neck s gong to ncrease hs love or respect for the socety s beyond us. Another and stll worse performance was requred, whch cannot but result n a postve njury to the school. We know that such ntatons are elsewhere carred on, yet they do not seem to be consstent wth the prncples and teachng of the nsttute. We do not want the reputaton of apng other colleges. The nsttute ought to stand ndependent and a model for all other colleges, schools, and semnares n the country. We at the nsttute are one brotherhood of honest, hard-worked students. We have a reputaton to make, and our reputaton makes that of the school. t behooves us to put asde everythng havng a backward tendency, and buld for our Alma Mater a sold reputaton n whch no flaw can be found, even by the most severe crtc. t s our hope, then, that the example of the two Sophomores wll be followed whenever lke ntatons are mposed by any socety n the school. THE resolve of the Athletc Club to open at least four of the events n the games to be held n the gymnasum Aprl 1 to members of outsde clubs, notably the Harvard Athletc Assocaton, the non Athletc Club, and the Jamaca Plan Boat Club, s a step n the rght drecton, and shows a confdence that we hope wll be verfed n the ablty of ts members to uphold the honor of the club aganst most worthy adversares. Certanly the other clubs cannot accuse ours of unfarness n the selecton of events, for they all have equal and some far greater advantages than ours for the practsng of them. Then, too, wth one excepton, ts records are nothng to brag of; and whle at the same tme the club does not doubt that t can better them, t would very much lke ts neghbors to compete wth ts members before the club gets too hgh n the scale of athletc prowess, - n fact, before t gets to such a heght that an nvtaton to ts games exercses the chllng effect that one to run wth the best " sprnters' " n the country does on men that have only the advantages of a gymnasum track, - twenty laps to the mle.

2 rr - f af1 a _ 110 THE TECH We most sncerely hope that the club's nvtaton may be accepted n the sprt wth whch t s gven; and our neghbors, should they see ft to accept, may rest assured of a most hearty welcome. Garntslutxthas " Each Man's Work shall be made Manfest." JOHN D. RNKLE, the second presdent of the Massachusetts nsttute of Technology, was born n the town of Root, Montgomery County, n the State of New York, Oct. 11, Hs early educatonal advantages were those furnshed by the dstrct school of that perod, and lke other country boys, he dscontnued study n summer as soon as he was old enough to be of use on the farm. At the age of sxteen, he attended a select school for three months, where he began the study of algebra and geometry. For the next ten years hs tme was spent n farm work, school keepng, and study, when n 1848, by the advce of the late Prof. Benjamn Perce (under whom he studed mathematcs), he entered the Lawrence Scentfc School; also devotng some tme to the study of astronomy at the Observatory, under /Drector W. C. Bond. He was apponted to a poston on the Amercan Ephemers and Nautcal Almanac n September, 1849, whch he stll retans; beng, snce the death of Prof. Perce, the oldest n length of servce on that work. He graduated from the Lawrence Scentfc School a Bachelor of Scence n 1851, recevng the same year from Harvard College the honorary degree of Master of Arts. n 1855, he publshed n the "Smthsonan Contrbutons to Knowledge" a paper of one hundred and twenty-seven quarto pages, enttled "'New Tables for determnng the Values of the Coeffcents n the Perturbatve Functon of Planetary Moton, whch depend upon the Rato of the Mean Dstances." He also establshed, n 1858, the.mathematcal Monthly, whch was dscontnued at the close of the thrd year, on account of the breakng out of the cvl war. Prof. Runkle was early nterested n the plans for the establshment of the nsttute of Technology, and was one of the frst teachers n the school, whch was held temporarly, durng the erecton of the present buldng, n rooms on Summer Street. On the establshment of the school n ts new quarters, n the sprng of 1865, he was elected professor of mathe. matcs, whch poston he stll holds. n the autumn of 1868, n consequence of the llness of Presdent Rogers, he was elected by the corporaton actng presdent, and presdent n 1870, whch poston he resgned n Durng these ten years of servce, besdes the extenson of the quanttatve chemcal laboratory, the followng new departments wee establshed under hs drecton:- The physcal laboratory n The mnng laboratory n The Lowell School of Practcal Desgn n The Dxwell engne and calormeter n The mneralogcal laboratory n The drll hall and gymnasum n The woman's chemcal laboratory n 1876, wth the co-operaton of the Woman's Educatonal Assocaton. The organc chemcal laboratory s The mechanc arts shops and School of Mechanc Arts n 1876, by the ad of the Mechancs Chartable Assocaton. The bologcal laboratory n n addton to the labor consequent on the ntroducton and development of these mportant features, he was called upon to make stll more manfest hs unusual pluck and energy. The great fre, whch dealt such a severe blow to the commercal nterests of ths cty n the autumn of 1872, was followed, as s well known, n the subsequent years by the long and wdespread depresson n the busness of the country at large. The resources of Boston beng thus doubly taxed, many of the earnest supporters of the nsttute were unable to ad ts _l Be

3 THE TECH. cause as formerly. Ths crcumstance, together wth the decrease of ncome from students, owng to the general busness depresson everywhere prevalng, serously checked the onward progress of the nsttute. Presdent Runkle, by vrtue of hs occupancy of the executve char, was called upon durng ths dark perod to bear the chef burden of these reverses. But as wll be seen above, not only dd he carry the nsttuton safely through ths crtcal perod, but also largely ncreased ts educatonal facltes. He had constantly n mnd the development of the school on the bass of the orgnal plan and scope, wth the sprt of whch le was so thoroughly mbued. The devoton and energy whch under such adverse crcumstances could establsh one new departure for every year of admnstraton should be held n grateful remembrance by all who proft by these ncreased facltes. Throughout, hs watchword seems to have been, "Whatsoever thy hand fndeth to do, do t wth thy mght." The mnng laboratory was conceved and planned by Presdent Runkle. Wth a vew to makng the students of the nsttute acquanted wth those who mght be ther future employers, and thus openng up a channel of communcaton for mutual beneft, he organzed expedtons of students and professors, n the face of great dffcultes, and vsted Colorado and other mnng regons of the West n two successve summer vacatons. As a result of ths undertakng, he conceved the dea of a practcal mnng laboratory, whch he mmedately put nto executon. The establshment of the School of Mechanc Arts s also due entrely to the exertons of Presdent Runkle. n a vst to the Centennal Exposton, held n Phladelpha n 1876, hs attenton was attracted by the unque exhbt of the Russan schools at Moscow. He was quck to perceve the practcal value of ths method of teachng, consstng of nstructon n the use of tools, as dstngushed from the art of constructon. The Russan commssoners, observng hs apprecaton, presented hm wth the greater part of ther exhbt; and, aded by ths, he at once prepared plans for the erecton of a buldng n connecton wth the nsttute for the purpose of teachng ths system. These plans were speedly executed, and a report prepared two years later was sent to Russa, and resulted n the presentaton to the nsttute of a stll more complete set of models, by the command of the Czar. The ncessant stran both of mnd and body caused by these untrng efforts for the support of the nsttuton, whose nterests he had made so entrely hs own, compelled hm to resgn n 1878, and take a well-earned rest by a twoyears' vst to Europe. Even then, always mndful of the cause of techncal educaton, he made a valuable and thorough examnaton of the Contnental schools whose specalty s nstructon of that nature. The result of these observatons he emboded n a paper read before the Socety of Arts shortly after hs return, a full report of whch was publshed n the New Engld and manufacturer for Aprl 15, n 1880 he returned to the nsttute, to resume hs dutes as professor of mathematcs. The Steam:-Eagne ndcator, and what t ndcates.. THE' followng dagrams have been taken ths school year by members of the Senor Class n Mechancal Engneerng; and as each dagram has some specal feature, we hope the explanaton wll prove nterestng. The dagrams shown n Fg. 1 were taken at the same nstant from both ends of the cylnder. The dagram on the left shows a very bad adjustment of the steam valve, - a defect whch the ndcator alone can show, as the engne to all outward appearance was runnng perfectly. The admsson valve does not open untl the pston has started on ts stroke, hence we have the curved steam lne E C A. From the pont of cut-off A we have a far card up to the pont E on the return stroke. ll

4 112 THE TECH _ Whle the pston s changng ts drecton of moton at the end of the stroke, the pencl of the ndcator falls to the lower pont of the lne E, showng that the compressed steam has escaped n some way, ether through the packng rngs of the pston or through the exhaust valve, probably the latter. The dagram on the rght of Fg. 1 s a far card n every way, although more compresson would have mproved t; and f the steam valve had opened sooner, we should have had a square corner at D nstead of the The greatest pressure ob- round one shown. taned n the lefthand dagram was 39.4 bs., C whle n the r ghthand dagram the greatest pres- \ sure was 48.7 / V lbs. Ths dfference s due to ' the late adms- Sen son of the steam, the pston, n realty, runnng away from the steam, so that the maxmum pres-. sure was not \ Ac< - reached before cut-off occurred. The mean effec- >-- tve pressure for -- =-- the left-hand dagram was 18 lbs., whle the same for the other dagram was 19.5 lbs. ; and although there s lttle dfference between the mean effectve pressures, yet f we look at the ponts of cutoff A and D, we see that a larger porton of the cylnder volume has been flled wth steam n the former than n the latter case. The lefthand dagram shows us that 42.2 lbs. of water were evaporated per hour for each ndcated horse-power, whle the rght-hand dagram used only 33.2 lbs. per horse-power. For the same amount of work there s a gan of about 22 per cent n favor of usng the steam as ndcated n the rght-hand dagram. Ths dfference s caused entrely by the wrong settng of the valve; for after adjustng the valve, the dagrams from both ends of the cylnder dffered n no essental part. The dagram shows exactly the amount of steam used n the cylnder, but does not ndcate the amount of water carrred along wth the steam from the boler. The actual amount of water passng through the cylnder can only be determned by weghng the amount fed nto the boler and 1.B 27 evaporated. But.2*. although the da- /, grams do not tell us precsely the / quantty of water ^^ ^evaporated, yet ^. they do show us C-6 ^the great dffer- 1e- 30o ence exstng n the manner of usng 'the steam..the dagrams shown n Fg. 2 were taken from A. an engne dong ts ordnary work, although at tmes t s called upon to do consderable more than s here ndcated. The steam used by ths engne s suppled through the Holly system of underground ppes, the steam beng generated at a central staton. The engne s stuated on the lowest ground to whch steam s run, and consderable trouble s caused by the condensed steam gettng nto the cylnder n large quanttes at every stroke. A very small quantty of steam was requred to do the work, hence the steam valves opened but an nstant, and the work was done by the expanson of the steam. The most strkng feature of the dagrams s -T e 1 m

5 _ the pecular compresson curve a b. Ths was at frst thought to be the fault of the ndcator; but the nstrument was new and worked perfectly well on other engnes, and gave ths lne at three dstnct tests, the ndcator workng perfectly on other engnes between these tests. The corner a was not so sharp at tmes, and the trouble was undoubtedly due to the large quantty of water n the cylnder not havng the means of escapng as freely on ths end as on the other, the quantty of water varyng at tmes. The pston of the engne strkng the water on the return stroke caused a sudden - rse n pressure, whch became so great that the water was forced through the pston rngs and exhaust valve, the fallng of pressure to b at the end of the stroke ndcatng such leaks. Owng to the lost moton n the stem of the steam valve of the rght-hand dagram, the valve was not fully opened, and the pressure beng on ths account reduced, we do not get so hgh an admsson lne as on the other dagram. The rse at c n the expanson curve of.the rght-hand dagram was undoubtedly caused by the steam blowng through the pston rngs as soon as compresson commenced on the other sde of the pston. The dagram n Fg. 3 was taken from a large beam engne n the rollng mll of the Bay State ron Works at South Boston. The engne drves the ron rolls, and when the ron runs through, has to do a large amount of work : but when the ron drops out, the engne has nothng to do but drve the rolls. The fgure shows n realty two dagrams, the pencl beng held to the paper durng two consecutve revolutons; the dagram above the atmospherc lne beng taken whle the ron was n the rolls, and the ron rollng out on the return stroke. The dagran for the lfext stroke for ths end of the cylnder was the one shown below the atmospherc THE TECH. ~r lne. The governor controls the engne by openng the steam valves more or less as occason requres. When the ron was out of the rolls,very lttle steam was needed, and the pencl rose only to the pont f; so that as the pston receded from the end of the cylnder, the pressure dropped by expanson below the atmospherc lne. n ths case, durng the latter part of the stroke the atmospherc or back pressure on one sde of the pston s greater than the steam pressure on the other sde, and ' hence tends to ^ stop the engne, whch s just what s wanted ^ /O. to prevent the... = -^*". *^ engne from run-- nng too fast when the ron s out of the rolls. t wll be notced that the back pressure lnes of both dagrams meet at g, and concde on the return stroke. The dagrams were taken just before the engne stopped workng, and the steam pressure was low. H. G. M. L _ Na o.b oatces. 113 HAMLET: A Tragedy. By W. Shakespeare. The plot andc executon of ths producton, though excellent n some thngs, are nevertheless open to grave objectons. The hero, a hypochondrac Dane, s altogether too sluggsh to sut modern deas: he has nothng of the dash and vgor of Olver Doud Byron n " Across the Contnent." The dalogue and rhetorcal fgures are also qute faulty n several places. For nstance, ths same Dane asks whether he shall "take arms aganst a sea of troubles," when everybody knows a man would say, "Dam a sea of troubles."

Morrell, head chemst at the Cambra ron Works at Johnstown, Pa, Mr. Norrs, of the Class of '81, has been enabled to send to Prof. Wng, for use n the quanttatve laboratory, a complete set of notes on the methods of analyss used there. These methods were devsed by Mr. Morrell, and are used only at those works. The notes are to be papyrographed, and ntroduced here n the laboratory for the beneft of the students. The thanks of all nterested n the quanttatve laboratory are due to Mr. Nolrrs for hs pans, and especally to Mr. Morrell for hs kndness n allowng hs own specal method to be sent here. Prof. Wng has on hand a consderable amount of " Orange No. 3" for purposes of quanttatve analyss, and n the nterest of chemstry would be glad to supply any laboratory desrng some of the artcle. Ths was frst manufactured as an anlne dye, but was found useless for that purpose, and the manufacture of t n ths country ceased n consequence. t s stll manufactured n small quanttes n Germany for use n chemcal analyss, as t has been found very valuable n that capacty.

Alas for the washwoman's boy, As he sngs n the hall so gay, And coolly presents hs bll, Whch he daly mplores me to pay And the stately bloods go on To the club-house over the hll; But, oh, for the touch of a vanshed V, And the sound of a chnk that s stll!

The Engneer now becomes a journal of sxteen pages, publshed fortnghtly, and devoted, as ts ttle ndcates, to mechancal engneerng and the alled arts. t s especally a paper for practcal men, and contans descrptons of new machnery, hnts and shop knks, whch often prove nvaluable to men who am to do ther work by the best and quckest methods. The last number, March 15, gves an account-- of specal nterest to our students -of the "summer school of engneerng" as carred out by the professors and students of the Columba School of Mnes. The Aprl Atlantc gves us the concluson of Lathrop's short seral, "An Echo of Passon," n chapters X.-X., whle Elzabeth Stuart Phelps begns a new seral story, "Dr. L:y," whch cannot fal to attract attenton, the name of the author beng suffcent to nsure a host of readers. Two chapters of "'The House of a Merchant Prnce," and the frst paper by E. W. Hlgard on "Progress n Agrculture by Educaton and Government Ad," complete the contnued papers of the number. For shrt stores we fnd Mss Woolson's "n Vence," and Mr. Dennng's account of " Jacob's nsurance." The leadng artcle by John Fske, "Europe before the Arrval of Man," wll be found of great scentfc nterest, whle Edward Farrer contrbutes a very engagng artcle on "Folk-Lore of Lower Canadt." These, wth other nterestng artcles, poems, revews of recent hooks, and a dversfed Contrbutors' Club, complete a number whch mantans well the hgh standard of the magazne.
