agree with the latter in the relation of cultures 3 and 4. By trans- 
piration the soil of 4 is considerably better than that of 3, but by the 
other criteria it is a 
trifle poorer. Besides 
this discrepancy there 
appears a rather 
markeddisagreement 
between the differ- 
ence between 1 and 2 
and that between 5 
and 6. Comparing
