Losses to cotton, what to look for and where to find it, being one of a series of articles in relation to crops, their common diseases and insect pests to which they are subject . a natural stage of the i)lants development. It occurs most frequently in extremes of either dry orwet weather or during the change from one extreme to an-other. It may occur to some extent under normal climaticconditions, especially if the cotton plants are too thick orthe variety of cotton is one which develops a very largenumber of bolls in Y)roportion to the leaf surface. During a normal period of growth the plants put outas many boll forms as would quickly mature should favor-able conditions continue. If a very dry period follows this,interfering with the supply of nutriment and moisture, apartial withholding of tissue-forming material results at avery critical period in the life of the boll, thus forcing thetissues into an unnaturally matured condition. A long rainy season may also cause the young bolls tofall, the soil being so saturated with water as to interferewith the roots absorption and to disturb the assimilativeactivity of the leaves.

Wlien the cotton is putting on squares or blooming, theclaimant often contends that hail knocked the squares off,when it is a matter of common knowledge that cotton willordinarily throw off two or three times as many squaresas it will put on bolls. It is as natural for cotton to shedits squares as it is for the cherry and apple tree to shedtheir blossoms. The more or less complete separation of the squaresat the line of division between the healthy and dying por-tion depends upon
