it was shown that this soil is not acid. 
The rirst series of the tests consisted in merely 
adding the commercial fertilizers to the soil at the time 
of planting, the soil being well mixed to distribute the 
fertilizers. The experiment was reveated three times, 
the results of each run corresponding yuite uniformly with 
those of the otner runs. ‘The results here presented are 
those obtained in the third trial. Only these are used 
because they show, just as well as more taovles would, what 
results were obtained, and further they are more to be 
relied upon because they were oodtained under better growing 
conditions and because the author by this time was able to 
manipulate with greater accuracy. In these tests as in all 
the others transjiration and g.i’een weight are the factors 
taken to indicate the growth.
