Gossypol in Cottonseed 
291 
seed from Bells, Tenn. (Compare seed of 1917, 1918, and 1919.) Smaller 
annual variations were noted in certain other seeds, and practically none 
in others. The authors* series, however, is rather limited, and it is 
possible that other large annual variations occur frequently in other 
varieties, particularly in regions which have variable or occasionally 
unfavorable weather conditions.

1 Probably the first year's growth froxn seeds imported into this region. 
1 Received from the agricultural experiment station. 
* Used for feeding tests. 
4 Hie Bureau of Plant Industry distributes seed and receives from planters samples of their trial crops 
for examination. These seeds were composite samples from a wide range of territory. 
8 Estimated on the basis of 75 per cent gossypol in aniline gossypol. 
8 Received from planter. 
7 Received from seed dealer. Seed probably from immediately adjacent territory. 
Table III also shows that the same variety grown in widely separated 
regions may or may not contain different quantities of gossypol. This 
indicates that influences other than those of a varietal character play 
a significant r 61 e. In direct agreement with this deduction is the observa¬ 
tion that different varieties grown in the same region contained approxi¬ 
mately the same quantity of gossypol. One exception was Lone Star 
from Bard, Calif., which was much lower in gossypol than Durango from
