To help Mr. Swingle in his work on the pistachio-nut, which may prove a new nut industry for California, the Office is searching for a Chinese species that will resist cold, a species native in Afghanistan that will resist alkali, the mastick and terebinth of southern Europe, and a native Texan species that Mr. Swingle thinks will be valuable for use as- stocks.
