132 (a) Height. Practically uniform throughout. If anything, the plants of the closer sowings were smaller than those of the wider sowings.

(b) Flowering Curve,-The flowering curve is probably the best method ot expressing the amount of vegetative development shown by the plant, since it is directly dependent on the branching system. The curves for 1915 are depicted on the accompanying graph.

It will be seen that root limitation did not exert any definite depressing effect except in the closest sowings, i.e., 80 by 45 and 90 by 30. Very little difference existed between the medium sowings, i.e., 90 by 60 and 100 by 45, but, if anything, 100 by 45 was the better.

The largest number of flowers per plant was obtained from the widest sowing, i.e., 120 by 45.

(c) The Boiling Curve.—The boiling curve is obviously the flowering curve minus the amount lost by shedding. As it proved practically uniform for all plots except the widest sowing (120 by 45), it may be taken that the amount of shedding was constant, with the one exception named. It has been found repeatedly in pedigree work that, although the number of bolls per plant is immensely increased by wide sowing, the amount of shedding is also greater.

This is largely due to the lack of shelter, and the increased evaporation induced by the cold, dry winds of winter.
