Pendleton: A Study of Soil Types 



447 



Comparing the more satisfactory grains, milo A and millet, it will 

 be seen that there is somewhat of a parallelism from soil to soil. The 

 legumes do not always respond similarly to the grains, as in the Diablo 

 first crop, yet in the Diablo second crop and the Altainont first and 

 second crops the response of grain and legume seems quite similar. 

 Hence, it is not safe in every case to judge as to the relationships 

 shown by legumes and non-legumes.

Considering all the variations, one might say that soil no. 23 was 

 seemingly among the better soils, and soils nos. 16 and 22 among the 

 poorer soils. Yet when discussing whether the soils be the same or 

 similar, according to the criterion of the dry weight, one of the Han- 

 ford groups will be similar according to one crop, and an overlapping 

 group similar according to the second crop. It can be said with rea- 

 sonable certainty that these Hanford soils are not closely similar to 

 one another.
