7. The diversity that may occur within one year is represented 
in the following table 2, but it should be mentioned that Experiment 
7 were overcrowded inside trees in which the increment of growth 
was fractional only and the bark poor as a consequence.

s the yield of latex variable but the latex is variable per se. From 
the same group of trees 30 fluid ozs. of latex was taken from the bulk 
daily, coagulated and weighed separately, with the following result : —
