The excessive growth of certain water plants in ponds and streamsdevoted to fish breeding is sometimes a source of trouble and loss. Inorder to control this difficulty, blue vitriol has been used as an algicide,and sometimes the results have been satisfactory. Experiments with thevitriol have been conducted by the U. S. Bureau of Fisheries and the U. S.Department of Agriculture. A practical problem arising in the use of such an irritant caustic isto ascertain the strength of a solution which will destroy the alga; and notinjure the fish or fish food. Useful articles in this connection are those ofMr. M. C. Marsh, published in the Bulletin of the Fisheries Bureau, and inthe Transactions of the American Fisheries Society for 1905, and Bulletins

FOREST, FISH AND GAME COMMISSIONER. 22g No. 64 and 76 of the Department of Agriculture, describing the studiesof Messrs. George T. Moore and Karl F. Kellerman. It is recorded that a ratio of one part of blue vitriol, or copper sul-phate, to one million parts of water will not injure black bass eggs or fry,but it has proved fatal to brook trout even in a weaker solution. Courtesies Plans of black bass stations have been furnished by the U. S. Fish-eries Bureau for consultation in establishing a pond station at Constantia.The Commission is indebted to that bureau also for a set of blank formsused in its hatcheries, for 170,000 brook trout fry, reared at the Cape Vin-cent station, 5,000,000 eggs of pike perch from the same establishment,4.250,000 lake trout eggs, forwarded from Northville, Mich., and 5,000,000eved whiterish eggs. From the New York Aquarium 8,000 lake trout frywere obtained in May, 1906, and were planted in Lake Ronkonkoma.Twenty-five thousand whitefish fry and pike perch
