At the close of Prof. Saunders' remarks some objections were made by members present to the use of Paris green on fruit soon after blossoming, and Prof. S. sustained the objection, in that the knowledge that the fruit had been showered with it would deter purchasers from receiving it, even if no poison could remain on it from spring to autumn. A man had brought to him potatoes to analyze for arsenic, on which Paris green had been used, and although it was shown to him that the poison did not reach the roots beneath the soil, and if it did it was insoluble and could not enter them, he was not satisfied until a careful analysis was made and no arsenic at all found in them. A member said that in mixing with plaster there should be 100 or 150 pounds of plaster to one of the Paris green, and that a smaller quantity, by weight, of flour would answer, as that is a more bulky article for the same weight. * * * * * OBSERVATIONS ON THE SALMON OF THE PACIFIC. By DAVID S. JORDAN and CHAS. H. GILBERT. During the most of the present year, the writers have been engaged in the study of the fishes of the Pacific coast of the United States, in the interest of the U.S. Fish Commission and the U.S. Census Bureau. The following pages contain the principal facts ascertained concerning the salmon of the Pacific coast. It is condensed from our report to the U.S. Census Bureau, by permission of Professor Goode, assistant in charge of fishery investigations. There are five species of salmon (Oncorhynchus) in the waters of the North Pacific. We have at present no evidence of the existence of any more on either the American or the Asiatic side. These species may be called the quinnat or king salmon, the blue-back salmon or red-fish, the silver salmon, the dog salmon, and the hump-back salmon, or _Oncorhynchus chouicha, nerka, kisutch, keta_, and _gorbuscha_. All these species are now known to occur in the waters of Kamtschatka as well as in those of Alaska and Oregon. As vernacular names of definite application, the following are on record: a. Quinnat--Chouicha, king salmon, e'quinna, saw-kwey, Chinnook salmon, Columbia River salmon, Sacramento salmon, tyee salmon, Monterey salmon, deep-water salmon, spring salmon, ek-ul-ba ("ekewan") (fall run). b. Blue-bock--krasnaya ryba, Alaska red-fish, Idaho red fish, sukkegh, Frazer's River salmon, rascal, oo-chooy-ha. c. Silver salmon--kisutch, winter salmon, hoopid, skowitz, coho, bielaya ryba, o-o-wun. d. Dog salmon--kayko, lekai, ktlawhy, qualoch, fall salmon, o-le-a-rah. The males of _all_ the species in the fall are usually known as dog salmon, or fall salmon. e. Hump-back--gorbuscha, haddo, hone, holia, lost salmon, Puget Sound salmon, dog salmon (of Alaska).
