The f,lo,o00 Prize foihlying.

AII the worlcl kuou's that the Dailg )ta'i'l , l'ith its characteristic cle,termination to lead the varl in journalistic entr:rprise, has offered a prize of dro-ooo ior the first flving m&chine ivhich successfulll flies from London to Nianchester. We canncrt speak too highly of our contemporary's p,ubiic spiritedness, aud \t'e prol)o.se to testiff to our ippreciation of, and to supple- ment, its efforts by a. cornp,aratively modest prize of our own. \\'e have decicled to offer a pr\zt: of d5oo to the make,r of th,e engine tha,t drives the flYing machine which rvins the Daily Mail pnze, provided he is a recognised British motcvr car manufacturer as defined lrv the Societv o,f l\Iotor Nlanufacturers. We feel that the Corrtiner-rill motor manufacturers re.luire l)o illcentive of this sort, lret:ause sever'al of them hnve giverl attention to the tlcsign and manLlfa(:tllre of extrli()rdinurill light lttrol motcrrs for the l)roPulsiorl of flf ing ma,chines for somc \ears. Speakiug _ from memi)r\ al()ne, we think rve are ilght in saving that _in the Paiis Sllon of rgor engines \\'ere exhlbited for the prop,ulsion of air ships rvhich rvere phenomenally light for their day. Again, speaking from mernory, we believe that the ueight \\'as about 5lbs. per horse- l)o\\rer. N<lrv, at least one French constructor is ieprrtc'd to have re(luced the rveight to z.z lb.s. per horse-power for a roo h.p. engine. antl as the British manllfrlctuner hirs not hitherto devoter'l him.seli to these verv'light engir-res n'e hope our 1;rize ma)'act as some snrall itcentiie tt, hinr to clo so, mor.c partictrlarly as rvi,thin Iim,its thre lruilding of specially light flying rnachirte mot-o,rs uill pronrote the improven-r'ent of the p,etrol t'ngine for ntotor c--a.r ltroptrlsion. In anl case, we are nrost r'lesirotts that the competitio,n for the Dtr il 11 )l ail prlz,e should be of An international r:haractt'r. As matters stand lt the moment it rvoulcl ill)l)ear as fh,ough the stmggle rvorrld b'e mainlv bet'rveen Flarrce enrl .{merica.

Vhat is Under the Paint ? We have before now drvelt upon the lact tltat motor c'ar manufactuiers, or perhaps \Ye shoul(l say the best of them, ore using steels of a much higher quality and greater strength ihan those u'hi<'h are employed in i'r,ginee'ring B'ork generally. Speaking broadly, the difference between the material may be taken as, sixty to one hundred. That is to say, roo ton steel is used b1' the best motor car manufactttrers, rvhereas sixty tom Iepresents abcrut the best en]p,lo,yed in the highest class of engineering in the o,rclinary rr,ay', anrl many lirms use nruch lou'er grade steel. becattse the purposes for which lt is c'mployed c]o no,t warrant the expense otr require the strerigth of the higher class metal. So far so good, bul s4ren we come to consider different malies of cars \.ie begin to see that the matter ASSumes anorther at:pect. For ii.rstance, rve might ha'r'e trvo cars by different nrakers, both cars being of about the same power and constructed accortlirtg to a simrlar specificatio'n, yet one may be price,l much higher tl.ran the other, tl'ough to the ele they might almost be regarded as sjstei machines and their exterior finish in every way equal. 'Ilhe matter is further complicated by the fact that in many cases-in fact, in alm,ost all cases-the higher class' material not only coists frorm double to trable the price o{ a meditrm class steel, but is much rnore difficuit to rvork, and, consequently, the lnbour r.xpended upon it is much greater. I'here are, 1Ye a,re glid to say. ,'s6px.atively ferv cars in which bad irateria,l is'user1, btrit there are a great many in which the rnaterial is o,nly of medium quality , and o'nly a.

select ferv in rvhich t)'re very best mater,,Ll for each part is used, almo,st regardless of rvhat it costs. It certainly seems advisable ihat the makers who are using the rery highest class materia.ls should make the fact plain
