I have proceeded thus far on the supposition that troughs of carbonized wood or other material are used. For the guidance of those who prefer glass grilles I quote the following remarks upon them from '' Harper's Magazine"* and from Dr. Slack's Catalogue of fish culturist's apparatus. " The Coste Hatching Tray (glass grilles) consists of a trough (made of earthen-ware, glass, or slate) about two feet long, six inches wide, and four inches deep. On the inside, about two and a half inches from the bottom, are small projections, upon which rests a glass grille, a species of gridiron formed of glass tubes placed closely together, the ends being confined in a wooden rack. There is a spout on one side and at the top of the box to run off the surplus water ; at the bottom and below the level of the grille are two other openings, usually stopped, but convenient to open in order to remove the sediment which from time to time collects. In using these hatching boxes water can be supplied from a water-cooler through a filter, * Harper's Magazine, November. 1868, pp. 728? 729- (.
