The lowest proportions arefound in the very early and very late sowings, though fortotally dissimihir reasons. The failures in the firstinstance are almost entirely due to a damping-off fungus,known as Sore-shin, which we must consider in furtherdetail, not merely because it is the only serious fungoiddisease of cotton in Egypt, but rather because certainconclusions drawn from the study of its relations totemperature will be used extensively for interpreting thegrowth-processes of its host. The Sore-shin ^—This facultativeparasite was first described in 1895 by Mr. G. F. Atkinson C 18 THE COTTON PLANT IN EGYPT chap. in the United States. It is j^
