At diiferent times during the past few years, cotton growers in the West Indies have oliserved that a considerable number of developing bolls have dropped from the plants, and that others have failed to develop properly, remaining in a dry and distorted condition attached to the plant, through the time required for the process of ripening, and often long after the crop was picked. The causes of the loss of bolls have been the subject of investigation from time to time, on the part of the officers of the Imperial Department of Agriculture, in response to requests from planters, who desired to know what they were, in order to be able to prevent further loss. In this connexion, anthracnose, boll rot and black lioU have been investigated, and have been found to be responsible for at least a portion of the injury. In a paper on Cotton Stainers (see West Indimi Bulletin, Vol. VII, p. 76), the Entomologist on the Staff of the Imperial Department of Agriculturestates that it is difficult to say exact- ly what the nature of the injury to cotton by cotton stainers is, and that the whole question of the nature and amount of the injury to the cotton plant, seed and fibre, might well form the subject of an extended investigation. The writer believes, however, that cotton stainers injure young cotton bolls by sucking the sap, and thus lessening the quantity of the yield of fibre, and perhaps also aifecting its quality; that they cause a certain amount of drying up of the pod; and that they check the growth of the pod and of the cotton inside it. In addi- tion to these injuries, the seed is often damaged to .such an extent as to interfere with its power of germination, and greatly to reduce the amount of oil that may be extracted from it.
