j9qiiatic liCe 163 will become apparent. A convenient stone will be selected, and beneath it, from end to end, a tunnel will be dug. Here the eggs will soon be deposited. When the young appear the parents guard them and lead them about the aquarium after the manner of the cich- lids. A hasty approach, or any action deemed hostile will cause the parents and brood to hastily retreat into their cov- ered trench, there to await the passing of the danger, though in the meantime one of the adults will appear at the opposite opening, apparently ready and eager to charge any possible foe. Mr. Robert J. Macrory, of the Pitts- burgh Aquarium Society, is the only aquarist, to the best of my knowledge, who has succeeded in spawning this spe- cies, and it was his pair that I observed as described. Unfortunately none of the young survived to maturity. The stone under which the tunnel was dug meas- ured fully five inches^ in diameter. Smoked Dogfish Experiments in smoking various spe- cies of fresh-water fish, begun at the Fairport, Mich., station of the United States Bureau of Fisheries about two years ago, have yielded interesting re- sults. The bowfin, or grindle. which usually is regarded as practically worthless, has been found to yield a very superior product when properly smoked. All who have eaten samples have spoken of the excellent texture and flavor of the meat, and some have pronounced it the best of smoked fish. Further experiments are being made with a view to obtaining a product which will appeal to the trade in appear- ance and quality. The bowfin is generally known through the Mississippi Basin as dogfish. and has been regarded as practically worthless. It is abundant in the Great Lakes and in sluggish waters from Min- nesota and New York to Florida and Texas. The proper utilization of this species will not only add another commercial product to the market, but also will tend to reduce the relative abundance of a species which is most predacious upon the other fishes that are more highly valued in the fresh state.

Pterophyllum scalare Paullin's Pterophyllum scalare have spawned again! This is not a startling announcement because it has happened a number of times, but very few aquar- ians have been privileged to witness the operation. It is doubtful if less excite- ment attends the function in any other species. Utterly oblivious to several pairs of eyes "glued to the glass," the pair proceeded. Other than the some- what methodical movements of the fish, little out of the ordinary would have been apparent to the average man. A broad, curved leaf of Sagittaria had been se-
