September, 1919 BETTER FRUIT Page 25 account of bitter pit, or the 45% large apples secured by light irrigation with 2% loss on account of bitter pit,—or, considering the whole crop, whether he prefers the 487o loss occasioned by heavy irrigation or the 1% of disease occurring with light irrigation. In considering the remaining type of physiological storage diseases, that is, those diseases influenced by storage conditions, we are dealing entirely with the artificial conditions by which we attempt to prolong the life of the fruit and hold it in good condition for later consumption. We store the apples either in a pit or a cellar, in an air-cooled storage house or in a commercial cold storage plant. The general plan upon which we work is, first of all, to hold the fruit as cool as possible in order to retard the ripening process. An apple is a living, breathing organism, and so long as it remains alive it is fit to eat. But when it reaches the end of its life it dies in a process we call physiological breakdown, a process previously men- tioned in connection with the troubles of abnormally large apples. But aside from keeping the apples cool and at the same time keeping them from freezing, there are some other factors concerned in the successful storage of apples, fac- tors which have been but imperfectly understood and consequently not given proper attention. Hence we find a number of storage diseases which can be traced to these conditions. From the nature of the case we naturally expect that the inlluence of storage conditions must affect the inter- nal physiology of the apple. Consider the disease we call "soft scald" or "deep scald," which is especially common on Jonathans, Romes and other red varie- ties. It first exhibits itself in a fading of the skin color, the coloring matter of the skin apparently passes into solution and spreads into the adjacent tissue. When the apples are freely exposed to warm air th
