growing period, such as South Dakota, will be higher in protein than 

 the acclimated seed, or vice versa, as has been suggested by Thatcher, 

 of the Washington Agricultural Experiment Station. For example' 

 the California seed when taken to South Dakota gives a crop with 

 13.9 per cent of protein, while the acclimated South Dakota seed 

 gives one with 12.9. On the other hand, South Dakota seed taken 

 to ( alifoniia yielded a grain with 9.1 per cent of protein, whereas the 

 acclimated California seed gave 9.9 per cent. These results show a 

 slight difference, thus corroborating this theory to a certain extent. 

 The differences are, however, so small and the experiment has been 

 of Mich >hort duration that this theory needs still further corrobora- 

 tion before it can be accepted absolutely. 



Following is the comparative composition of the California seed 

 taken to South Dakota and Kansas, and the South Dakota and 

 acclimated seed, and vice versa:

It \\ill thus be seen that in each case when California seed is sent 

 either to South Dakota or to Kansas the percentage of protein is 

 si. nn- A hat (though very little) increased over that grown continu- 

 ou>ly in South Dakota or Kansas. On the other hand, when wheats 

 n in South Dakota or Kansas are sent to California the reverse 

 i- true. 



INFLUENCE OF HEREDITY. 



Too much has been taken for granted regarding the influence of 

 heredity in plants. Without detracting from the power which 

 heredity may exert in the progeny of seed, the results here produced
