It will be seen that the yields are very variable. This is due 
principaliy to the varying conditions of the soil. Attention has 
been called on another page to the low depression running diagonally 
across the field. This was of stiff Cameron clay, very refractory and 
difficult to cultivate and flooded at times. Another cause of the 
differences in yield was the greater prevalence of Bermuda grass in 
~some places than in others. 
With reference to rows 20, 21, and 22, it should be stated that the 
low yields were due to still another factor. The stock for planting 
these three rows was, contrary to expectations, secured from material 
cut and dumped into a waste pile several months before. The cut- 
tings were badly withered, and, being planted in very dry soil in a 
season followed by a long dry summer, they did not start well. 
Many of the cuttings failed to grow, making the stand poor. During 
the entire two seasons it was very noticeable that these rows were 
much lighter than the contiguous rows of the same species but of 
- good stock.
