THE NEW EARTH 



hal waste of former years, is one problem ; how 

 to produce a maximum of meat, butter, eggs, 

 or milk at a minimum of cost, is another. It 

 would have been all Greek to a farmer of the 

 Old Earth to tell him of a dual-purpose cow, — 

 one that would produce milk and butter profit- 

 ably for home consumption and at the same 

 time be the mother of calves which, if desired, 

 would make marketable beef. It would have 

 been quite outside his line of vision, too, — a 

 study recently followed for some years, and suc- 

 cessfully, in one of the agricultural colleges, — 

 to educate, so to speak, the sheep to give birth 

 to their lambs earlier in the season in order to 

 give the farmer early spring lambs to put upon 

 the city market at a higher rate of profit. 



It would require volumes to describe the 

 many different ways in which practical scien- 

 tific men are now at work upon the problem of 

 producing better meat products. Take an illus- 

 tration: In Tennessee the growing of alfalfa 

 has come into favor, as it has in other states, as 

 a desirable food for stock. The State Experi- 

 ment Station of Tennessee, after the introduc- 

 tion of alfalfa began, set out to determine the 

 real value of the new food — was it any better
