This is the third report* of progress on the investigations pertaining to the holding of apples in storage which have been carried on since 1906 by the pomology section of the Iowa agricultural experiment station**. It covers work which has been in progress during the past five years and deals with several questions:
The temperature of fruit before and after storing; humidity of storage rooms; maturity of fruit when stored; size of apples; wrapping paper used in packing, and methods of storing; the control of certain apple rots which are liable to develop in storage, and the rate of cooling of apples when put into cold storage
