Book excerpt: Excerpt from Bulletin of the United States Fish Commission, 1884, Vol. 4 For several years a careful inspection of the marine products brought into the District of Columbia has been made under the direction of the health officer of the District. Five years ago an arrangement was perfected by Prof. S. F. Baird, Commissioner of Fisheries, with Hon. Smith Townshend, M. D., health officer, whereby the daily receipts of fresh fish, oysters, &c., should be tabulated and transmitted in monthly tables to the Fish Commission. These monthly tables have all been footed and transferred to yearly tables in this office. I am able herewith to present annual tables for 1879, 1880, 1881, 1882, and 1883 (Tables I, II, III, IV, V). The yield of shad and herring may be supposed to have been influenced somewhat by the artificial propagation under the direction of the United States Fish Commission, which has been carried on at the Potomac for a number of years. The run of shad and herring is also affected by the temperature, which varies somewhat for the same date in different years. This is presented in Tables VII to X, inclusive.
