THE PROPAGATION OF THE GOLDFISH such as have been kept in outdoor tanks and basins in favorable weather but which must be otherwise accommodated during the rigors of cold weather.

C. The ordinary goldfish will survive out-of-doors, if the ice is broken to admit air. The tanks should be of sufficient depth so as not to freeze solid, and straw or other materials should be packed about them for protec- tion. A board cover, with straw spread over it, should also be provided, to moderate the cold. An approved method is to permit an inch of ice to form, after which a hole should be cut and sufficient water removed to make a space of two inches between the ice and the water, and the hole closed with a cloth and a board. If the sides are protected, the cold will not cause a further freezing, and the air space will prevent suffiacation. The top of the tank may also be covered, after which the fishes will be in comfort until the advent of spring. Feeding is only necessary at long intervals. The fine breeds should be wintered in a greenhouse or in the cellar. Tanks or similar vessels will serve, but the best receptacles are fibre wash- tubs. These should be set upon supports near a window, for occasional ventilation, but no plants introduced unless the light is such that they will grow. The fishes should have ample water, five gallons per fish, if possible, and once a week a pail or two of water should be siphoned from the bottom around the edges, where the excrement will accumulate, and a like quantity of fresh water added, which has been moderated in tempera- ture.
