in the experimental garden ; the 

 question is whether this is main-

 we must look to the lateral branches 

 of the pedigree which are given 

 off every year, in which the seed is 

 increased in quantity for the mar- 

 ket as explained above. It is not 

 every culture that succeeds (e. g., 

 the Original Red Wheat) ; but it 

 is only about the successes that 

 records are published. 



The value of Hallett's work 

 is proved by the commercial suc- 

 cess of his races. ^ But he seldom 

 gives data of any value for scien- 

 tific purposes. Several of his pro- 

 ductions have found a wide sale, 

 especially in England, as for ex-

 His Chevalier barley and his two

Hallett asserts that, for each 

 sort, the rate of improvement grad-

 the end of many years the race 

 reaches its maximum and becomes
