Fishing; Fishes. 468 AMERICAN ANGLER'S These, as the reader will observe from the cut, are simply a succession of troughs placed one above the other. The water flowing from the stop-cock B, in any desired quantity, into the topmost trough, falls in little cascades into those below, which aerates it suificiently during the term of hatch- ing. By means of these troughs the fecundated eggs may be watched with care, and examined without the danger of dis- turbing the process of incubation, as would be the case if the spawn was placed in hatching-boxes, according to M. Gehin's plan, and deposited in the stream, and removed from it occasionally to examine them. The troughs may be placed ia any spare room where it is convenient to lead a small supply-pipe, and place another for the discharge of the water. They should be supplied to the depth of four inches with clean gravel and a little coarse sand. Bach trough should be raised somewhat at the end where it receives the overflow from the trough above, so as to cause a slight current. M. Coste recommends that the eggs be spread on closely-woven hurdles of willow, and sunk an inch or two below the surface; his reasons for doing so are given in a subsequent extract. If the bottoms of thp troughs are covered with gravel, the water—which may be supplied through a quarter-inch jiipe—should flow through them for a few days, so as to remove any impurity amongst the peb- Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly r
