O'Gara, Pathologist It has been said that "there is no royal road to potato-growing on the Pacific coast, " and this saying is decidedly true. While much may be said of the adapta- bility of many of the commercial vari- eties of potatoes grown in the East to this district, climatic conditions are more or less responsible for this. Little has been done to originate new varieties of potatoes for our particular climatic con- ditions, and the experimental work in the acclimatizing of the older commer- cial varieties so popular under eastern conditions has been very meager. The important matter of potato-growing in our district alone opens up a broad field for investigation, and, if prosecuted as it should, would certainly lead to im- portant results. It is commonly stated that this dis- trict is not a potato district. This state- ment would be entirely true if certain varieties of potatoes were to be planted and grown under unfavorable conditions. The matter of when to plant for both early and late varieties is a considera- tion so important that even the most adaptable varieties will not bring results if this one factor is overlooked. One of the greatest troubles experi- enced by potato growers is the so-called secondary sprouting, which usually oc- curs after the tubers have almost reached their full size. Usually this sprouting occurs during the middle of July, or a little later, depending upon the season. Another trouble is the erroneously named "dry rot, " which, after all, is not a rot, but rather a browning of the fibro-vascu- lar bundles in the tubers, and is physiolo- gical. We shall show that both these tro
