The most interesting results have, however, been furnished by an examination of the seed cotton. Nothing could be more definite than the effect of the climatic environment on the quality of the lint. It seems probable that the whole explanation of the quality of the lint, whether length, strength or the ginning percentage be considered, lies in the climatic environment during the period of maturation in the boll, provided that the water supply is adequate and cultivation normal.

It has been stated that warm nights and a comparatively humid atmosphere are the most favourable conditions for development. An inspection of the meteorological data will show that these conditions obtain during the first half of the life-history of the crop rather than during the second portion. Therefore if our hypothesis is correct, the early-maturing cotton should be of better quality than that gathered later on, even though the latter be the first picking from the parent plants.
