The Massachusetts Forestry Association has made publica request to the students olf the variouls colleges in and aboutBoston to aid in the Cord Wood Cutting Campaign to takeplace during the coming, Christmas recess. rhe sole object ofthis campaign is to relieve the scarcity in the fuel supply.

Referring to tllis, Professor Henry G. Pearson of the En,-lish Department, made the following statement: "This is reallya very important work, for the coal situation in Massachusettswithin the next month will become exceedingly acute. In theimmediate vicinity of my home in Newton Center there is ademand for forty or fifty men who are willin- to do this -work.They will be paid as high as $2.50 per day, dependin- on theirability as wood cutters. Thle work is to begin the dayv afterChristmas and. I believe, that it can be made to fulfill both awar time emergencv and a good time for the men conczerned."

All undergraduates who wish to avail themselves of thisopportunity should hand in their applications at the Bursar'sofice immediately.

The letter receivted frown Mr. Harris A. Reynolds, secretaryof the Massachusetts Forestry Association, is pulblishled in full

COMMUNICATION

'Mr. Paul Leollard.Massachusetts Institute of Tecllnology,Cambridwe, 'Kass.Dear Leonard:

The following is a brief statement ofour Student Cord W\ood Cutting, Cam-paignl.

Ow~ing to the present scarcity of cordwvoodl and the fact that the public iswvarnedl that wve can expect asevere shortage of coal, the _Massachu-setts Forestry Association believes thatev\ery effort should be inade to cut cordwvooh by those who are physically able.There is a. great scarcity of labor forthis wvork and the Associatioll has askedthe students of the various collegesabout Bostoll to consider cutting, cordwood during their Christmas lvacation,and has received a v-ery hearty response.

It is the purpose of the Associationto serve as an employment bureau toconnect the students who wrish to cutw^ood with the parties whlo are in needof such Inen. It is believed that wood-lots can be found w-ithlin reasonable di*-tanlce from Boston, by whlich the mencall return to their usual rooming placea t n igght. Ill some cases the work maybe so far from Boston that it will benecessary. to room and board ill thev-icinity. Thle usaces will depend uponthe ability of the men and where thewvood is cut by the cord, the local priceswsill hlold.

As this is really a -war emergencymleasure, it is the patriotic duty ofthose wbho can, to assist in this import-ault workd and it is hoped that many ofthe Technlology students, wvlo are notothlerwise employed, wvill consider ap-plving their energies to this work.

Not onlv is wvorzin- in the woods ahlea~lthful occupation. bult the satisfac-tiOII that conies from feelinm that oneis talking a part ill emergenclly work,itogether wvithl the compensation, wfillfully repay any one for the effort ex-penlded.

Siucerely yours,(II. A.) "PETE" REYNOLDS,

Secretary.

THE QUESTIONNAIRE

THE TECH has made arrangements whereby registrants at theInstitute still lbe aided in gaining a w-orkitl, knowledge ofthe nest draft questionnaire and its purpose. There is utn-

doubtedil- much uncertaintv about the near rulings and what willbe accomplisled by· them, but the interpretations of such men ashave volunteered their services wrill certainlv dispel most of it.

The lawyers echo have undertaken the work will gives essen-tially, information rather than advice. They are all members oflocal draft boards and the interpretations whicle' they will give arethe best obtainable. Of course there is nothing official about any-t'hing whlich their mayl say, but coming as it does from men who arecompetent to interpret the questionnaire. the information whlichthey axill adsvance wrill carry much Freight.

At the Convocation toda-: matters of interest to registrantsonly will be taken up. Therefore it has been requested that onlymen naho hase registered attend the meeting. Room IO-250 willnot seat the entire student body, but it will probably accommodateall men who are in the draft. If there are anv men who propose tocome to the Convocation merelv otlt of curiosity, let tHern realizethat thev~ asill most lik~elv- do so to the excltusion of registrants wh-loare vitalltv interested.

Finally Tlle Tech wislles to tak~e this opportunli-tyr of thlankingthe men cello hlave so kindlv, \-olutiteered their timie anal services tohelp Technology- registranlts.

Todav- +Xill usher into Technologyr another campaign. this timefor the Red Cross. In these davrs of campaign after campaign aw-orthv cause mayr be ov-erlook~ed. It is scarceli, necessanr to ev enmention the worthiness of the Red Cross. Di-, for that dollar and

"On land, the machine gun is consid-ered as an addition to the infantry orcavalry and not as constituting a sep-arate arm of the service.

NEW ELECTRICAL FEATURESAT GENERAL ELECTRIC CO.

Electrical Engineering Society TakesSecond Trip

Last Tlursday afternoon twentymembers of the Electrical EngineeringSociety took a trip to the General Elec-tric Company to observe several newfeatures which have been introducedthere by the engineers of the plant.

One of these features, in use in thesmall motor department, is a new speedindicator composed of a small centri-fugal pump, which is :fexibly coupled tothe motor, supporting a column ofwater in a calibrated tube. This in-dicator is very accurate, for the pres-sure of the water varies directly as thespeed of the motor.

A new idea in the transformer de-partment is a line condenser which isused to take up the lag of the trans-formers. Heretofore stationary con-densers have been impracticable becauseof their bulk and rotary synchronouscondensers vere largely used. The Gen-eral Electric engineers have developeda fised condenser which is built in units,less than a cubic foot in size, each unit| haing a rating of about five kilovolt-amperes.

A new feature in generator rotor de-sign is the one piece aluminum castarmature. Laminations having closedslots in the rim, instead of the usualopen ones, are assembled and put in amould where the aluminum casting ismale, leaving two solid rings at eachside. The effect of this smooth castingin contrast wvith the open slotted one,is the large deerease in wind resistance-when running and the increase of start-in- torque.

Government Sanction

A communication just received byPresident Jlaclaurin of Technology fromthe WV~ar Department states that theGovernment has nbow officially recog-nized two Reserve Officers' TrainingCorps units composed of TechnologyUlndergaduates, the Coast Artilleryand the other Signal Corps. This au-tion confirms with the seal of author-its the work that the Institute hasbeen taking up recently, and in facthad taken up even before the war wasdeclared.

The story of the development of thismovement, whicl is prominent amongthe many that the Institute has under-taken in the service of the country, isa very interesting one. Its beginningsreach back lona before the war in therealization on the part of Major Edwvin1'. Cole, U S. A.. retired, Professor of IAlilitary science at Technologoy. Warand engineering have in later years be-come so much involved one with theother that the Institute in its educa-tional work was directly in the linesmost necessary for the training of mili-tary and naval officers. An effort wasniade to make this plain to the au-tllorities, but until the beginning oftile war no action was taken in Wash-in-ton in the matter. As soon as warseas declared Dr. Maclaurin tenderel toPresident Wilson the Institute labtora-tories and instructing staff. It wassome time later that the War Depart-melnt sent to Boston a commission ofAirmi officers to look over the curricu-Ililn at Technology with a view to rat-ill- its possibilities in regard to mili-tary education. The report of thiscommission wvas practically that, withthe addition of some small amount ofspecial military training perhaps anhour or two a week, the courses atthe Institute were preciselv those which 3nvere required in military work. Since Ithat time the WTar Department has in In general way approved what has been Ipopularlv termed a four-year military;option at the Institute, but has been Iunable to act officially, until the de-tails of the courses could be fixed..This has been done and Technology has |now two recognize units of the R. O.T. C.

Before the official action was takenin the matter the Institute had alreadymade changes to comply with the R. O. TT. C. requirements. In fact, it was at|the Institute that the details of thegeneral plan were -orked out. Allthese factors were carefully detailed byMiajor Cole and the members of thefaculty.

Tile plans for courses of study relat-ing to technical education in the Ord-nlane and the Engineer Corps were alsomade with as much care and study asin the case of the other divisions. Thegovernment has not yet been able toaet on the outlines for these Ordnanceand Engineer Corps units, but it ishloped that they vill presently be ap-proved. They are virtually approvedby the WVar Department, but the workof fitting in the special training withwvlat is at tile Institute, a heavy andtrying scientific course of study has not|et been possible.

TIn the hope that tile outlines of thefoul-year military option might bereadly in time fo; the opening of theInstitute last fall, the Registrar circu-lated a questionnaaire among the stu-dents askiiig how mano would like to|tak;e up such an option. Although the>articulars about the course were ex-

Ieedingly hazy the replies ivere emi-|nently satisfactory and some four hun-

lredl of the students indicated a desire[to pursue such studies. W;hen schoolopened, however, the last of September,

[the War Departmellt wvas not ready,[although the Institute and the studentsi vere, and accordingly, on account of theentlllsiasm shown. the Advance Bat-talion weas or-anized by M~ajor Cole, totakve up military studies in addition tothe l'egular wVoIk. The men enrollingin the Advance Battalion wvere to wearregullationl uniformi and to devote extrallolrs to the military studies.

This idea lwas successful and servedin a measure to quiet the unrest thatleveloped when the students came back-to Techonoloav andl found that no rec-ounized military work avas open tothem. Practically the whtlole of the fourhundred wh1o had exmpressed interestjoined the battalion and wvith the fiveIllndredl freshmen to whom drill is cormpulsory by act of Congress, and whowvere also 'in kehaki, Teecinoloa~v took ona very military aspect. This eras themloi-e pronounced in that the men ofthe twxo Governlmenlt schools of avia,tion. the Army and the Navy. inumber-'in, 'about two hundred and fifty each.,,.ere also in uniform.

Some four or five wleeks ago wordwras receivted at the Institute that theGovernment wvould accept in part theplans for the military option, but thisvas put in a tentative way and hadapplication only for a year. On thebasis of this a R. O. T. C. ivas organ-ized, drawing- one hundred and fifty ornmoe mnen from the Advance Battalion.It ]has proceeded since its beginning on

the same general plans as those justnolw confirmed. Today the confirmationis complete as far as the units areconcerned, and there exists now at theInstitute a Reserve Officers' Training''l oup whose members come from theSophomore class, numbering 185 in theCoast Artillery unit and thirty in theSignal Corps. There remain in the Ad-vance Battalion of Sophomores and up-per classmen some 250, so that count-inM in the freshman and their officersthere are over one thousand of thestudents in Army uniform and, withthe aviation schools, about seventeenhundred men in the school echo are un-der military training. The R. O. T. C.groups have been dependent on one fea-fin e in military drill at the Institute.Nearly at the close of the negotiationsthe W0ar Department came upon therule that to secure the establishmentof a R. O. T. C. in a school two yearsof compulsory drill was necessary onthe part of the school. The faculty metthis requirement at a meeting some timeago, so that at Technology the studentwho enters now must take two yearsof military science and evolutions inplace of the one that has been requiredduring the past fifty years.

The meeting of the Boston Societyof Civil En-~ineers will be in the even-illg of Wredne~sday, December 19. Themnembers will assemble in building 2 inthe old Cafeteria for dinner and laterwill gather in Smith Hall, room 10-2500under the dome, for the addresses ofthe eveninog The principal one wrill begiven by Charles T. Alain `76, whosetopic will be the "Foundations of theNew Technologv Buildings." Mr Main,who has just been elected president ofthe American Society of Alechanical En-"g~ineers, wvas the consulting engineerwith reference to these foundations. Itis expected that President -Aaclaurinwvill be present.

After the mleeting, the engineers willhave the opportunity of visiting thelabora tories, which woill be opened fortheir benefit. One of the special fea-tures wvill be the little Niagara, of294,000 grallonls a minute, impelled bythe areat W\ortbington pump. This hasbeen termied "the biggest bit of equip-mnent ever giv en to students in thelaboratory to work with."

G. B. HAVEN TELLS AEROCLIUB OF "AIRPLANE FABtRICS"

Thle subject of Professor Georg e B.H-aven's address at the meeting of theNero Club last Friday evening wias"Airpulale Fabrics." The lecture wras

complete in detail, and wvas illustratedto advantage with slides.

He first discussed the classes offabrics 'which. are of interest to the air-.craft engineer-tire fabrics for wheeltires, balloon fabrics for dirigibles, andwing fabrics for airplane wiings. Heleclared that cotton would probably bethe ultinlate material; and that linenand flaxs ere very desirable, but arealso very scarce. Silk is too costly, andtherefore it is not often used., Ramiefiber is used, and there are other eom-positions which are in the experimentalstage only.

Professor Haven reviewed briefly thetypical manipulations of a fiber in itsmanufacture, taking cotton as an exam-ple. He sholwed samples, and illustratedeach stage with slides. He describedthe charactel of tile yarns and fabrics;and reviewed the rules for twisting.He told of the methods by which thefabrics rendered impervious; the dop-ing, the r ubberizing and the varnish-inr, and also discussed the compositionof the dope, and the hot calendering

The testing of the materials is an im-portant factor. There are two metlodsused-the "strip" test and the "crab"test. The effect of moisture nnd thejaw speed must also be taken into con-sideration. The professor described tileeffect of weather and exposure, and thenlethodls of re-doping, We comparedlastly, the American and the Englishspecifications for airplane fabrics.

There were but nine gas-cloud attacksmade in all against the British line."'The idea of gas-warfare is to -et ahigher concentration than the enemy-"The gas-concentration at the beginningof the war was about one part in tenthousand; now it is about one part inone thousand.

The gas bomb. vas the nest develop-Iment to come to the front. At first, noone realized the importance of thismethod, for they thought that the num-ber of shells -which would be necessarywould be prohibitive. Considering thatthe ratio of the amounts which a bomband a cylinder contain are respectivelyabout sixty to several hundred, and thata large number of cylinders were used,the use of gas bombs would seem anintpossibility. Still, when using thebomb, the shell can be placed, and, inthis way, the highest concentration -isnear the enemy's trench rather thannear your own.

It was found, in some cases wherea very high explosive shell would nottouch a gun crewv, a gas shell wouldhave great effect.

A newc gas 'was now introduced xwhichhad a harassing rather than deadly ef-feet upon the soldier When the menare compelled to ivear their masks fora great length of time, or are compelledeven to sleep in them, because theenemy keep throing these shells nearthem, the morale of the soldier islowered a great deal.

Some of the gases used are bromethyl,nmethyl, ketone and ethyliods acetate,and benzol bromides Dichlorethyl sul-phide. sometimes called "mustard" gas,wrill blind a man for about too weeks

and affects the throat and lungs Thereis another gas called "sneezing' gas.The "mustard" -as causes much dis-

I tress and makes a man wisl to do any-thins but fight; it is not, howvever,fatal. Prussic acid is not used.

Cvlinders filled with baas wrere intro-iluced on the front at one time, Butin this case, the infantry had to be de-pelded llpon to carry the cylinders.

Th'I'e -as bomb method has replacedthis inferior n method. Rapid-firingtrench moltals and projectiles are bestfor this purpose, and are worked totile uItmost. Sllrapnel and high explo-sives are sometimes mixed with the gas.

Professor Talbot, chairman, then in-troduced Professor Spear as the chair-man for the coming year.

Major Auld of the British Mission tothe United States addressed a jointmeeting, of the Northeastern Section ofthe American Chemical Society and theChemical Society of the Institute lastFriday evening in Huntington Hall inthe Rogers building. The major's talkconcerned both the offense and the de-fense of the gas attack-

The use of gases is one of thegreatest and most important develop-ments of modern warfare. It was firstused against the French troops on theWestern front in 1915. That first at-tack came as a complete surprise andthe Allies were overwhelmed.

Immediately, an investigation was seton foot; and, by methods of elimination,for few gases could be obtained inlarge enough quantities and transportedeasily enough, it was determined thatthe Germans had used chlorine. Thisdecision was later confirmed by cap-tured enemy documents.

The respirators used to protect themen from this gas were simply padsof cotton wool. Since the concentrationof gas during Qese first attacks waslow, these improvised masks were effi-cient enough. "The idea of the respira-tor is to protect against the unknown."Those which the British use consist ofa box, containing the chemicals, whichis worn on the chest, and a mask whichfits over the head tightly, thus protect-ing the eyes as well. The Germanswear a similar mask, but the can con-taininog the chemicals is carried on thetop of the head instead of on the chest.To show the thoroughness with -whichthe chemists have solved the problem,Major Auld stated that the masks nowused would withstand practically any |g-as except carbon monoxide.

The cloud method of gas attack wvas Iquite uncertain, for the wind even]when it was favorable, was liable to,change at any moment. The Germanswere once caught by this freak of for-tune: the gas cloud wes about halfw-ax bptw-een the opposing fi*t-lmetrenches awhen the breeze veered aroundand the cloud returned.

The first gas attack made against theBritish line lasted one and one-halfhours; the second, made on Klay 10,191;, lasted three hours; while thethird, made in December, lasted onlythirty minutes. In this last one, theconcentration was -reatly increased.

8.30 o'clock and the orchestra struckip on the miinute, but fea couples werepresent until a half-hour later. Fromthen on, howsoever, the floor was alwaysfilled until the dance finally came to anend.
