 only 20 Ills, of hay |>er ilay we get— itothiug e.xeepi niaiuirc. 

 If w«' furnisli 2"> ll»s. of hay per day, or its eipiivalent, we get, 

 s;iy half a fniund of cheese i>er day. If we furnish ;J0 Ihs. we 

 got one |>uund of cheese jmt day, or ytw lbs. a year. We may 

 not gel the one pound of eiieese every ilay in the year; sometimes 

 the cow, in.stead of givins; milk, is furnishing food for her endtryo 

 calf, oi slorin-.; U|i fat an i tiesh ; and this fat and llebh will Ik- u.sed 

 by and by to proiluce milk. Hut it all comes from tin- ftxxl eaten 

 by the cow; and is e(jii.d lo one pound of chees*- per day for IJO 

 lbs. of hay or its «'<piivalent consumed; 20 lbs. of hay gives 

 us nothing; 2.") lbs. of hay givi-s us half a pound of cluvse, or 

 40 lbs. of cheese from one ton of hay ; 30 lbs. irives us one 

 pound, or OOi lbs. of clu-^-se from (»ne ton of h.-iy ; 35 lbs. 

 gives us \\ lbs., or b.V , lbs. of cheese to one Ion of hay; 40 

 ll)s. gives us 2 lbs of cheese, or KX) lbs. of cheese from one ton 

 <»f hiy; 45 Ins. gives us 21 lbs. of cheese, or 111 lbs. of cheese 

 from one ton of hay; 50 lbs. jrives us 3 lbs. of cheese, or 120 lbs. of 

 cheese fn»m one ton of hay. 



On tliis bjisis, one ton of hay, in exr^ss of the mnount rrqi/inil to 

 hrp up the an'mul hint and 8u«!ti'n the ritiU ftiiictiong, gives us 200 

 lbs. of cheese. The point I wish to illustrite by these figures, 

 which are of course hypothetic d, is, that it is exceedingly desiral)le 

 to get animals that will cat, di.'est, and assimil.ite a large amount of 

 food, over and above that re(iuin-d lo keep up the beat of the 

 body and sustain the vital functions. When a cow eats only 25 

 lbs. of bay a day, it retiuires one ton of hay to produce 40 

 lbs. of cheese. But if we could induce her to eat, digest, and 

 a.ssimilate 50 lbs. a day, one Ion would produce 120 1I)S. of 

 cheese. If a cow eats 33 lbs. of hay per day, or its equivalent 

 in grass, it will reijuire four acres of land, with a productive 

 capa' ity ecjual lo 1^ tons of hay per aero, to keep her a year. 

 Such a cow, according to the figures given above, will produce 

 401 i lbs. of cheese a year, or its equivalent in growth A 

 farm of yo acres, on this basis, would support 20 cows, yielding,
