— 123 — Effect of Irrigation on the Strength of Cotton.—It would not appear that there was any definite connection between the length and strength of the fibre beyond the fact that both are affected by changes in the environment. The variations noted in the laboratory are small in amount, but that they are definite and significant is proved by the fact that in spite of the different climatic conditions obtaining during the two seasons 1914 and 1915, the results of the experiment are qualitatively the same, although they differ quantitatively.

It has been most encouraging to find that in general the brokers' valuation of samples from the different experimental plots agrees with the laboratory results : Eileet of Varying Amounts of Water on the Breaking Strain of the Cotton Fibre.
