secretion and arranged in a boat-shaped 

 mass with the aid of the hind legs ; her 

 duty being now fulfilled she soon dies. 



Each egg has a trap-door arrange- 

 ment at the bottom, through which the 

 little wriggler drops out into the water ; 

 thus again commences the life cycle of 

 the insect.

 and fats being carefully removed. The 

 resultant food should not only be prop- 

 erly compounded but it should contain 

 some sort of a binder, chicken egg or 

 agar agar, to prevent it dissolving or 

 breaking up and polluting the water. 



To secure a food as a substitute for 

 larval mosquitoes, this insect was ana- 

 lysed by a chemist. With this informa- 

 tion it was possible to make a mixture 

 the elements of which approximate those 

 of the mosquito, viz., two pints of wheat 

 flour boiled like mash, one chicken egg, 

 one and one-half scruples of sugar and 

 one-fifth of a pint of lean, boiled pork. 

 These ingredients are thoroughly mixed 

 and then dried, keeping perfectly for a 

 long time. 



Food mixtures, regardless of how pre- 

 pared, will if used without discrimina- 

 tion, pollute the water. For this reason 

 Japanese breeders invariably use feed- 

 ing pans. These are unglazed porcelain 

 dishes, very shallow, and about eighteen 

 inches in diameter. The dishes are sus- 

 pended by three strong strings from poles 

 thrust into the banks of the pond, and 

 extend about two feet from the shore. 

 Into these the foods are placed with 

 dippers. For larval fish the pans are 

 suspended about two inches below the 

 surface of the water, while for well- 

 grown young and adults the depth may 

 he five inches.

Luciocephalus pulcher 



C. J. HEEDE 



Along the eastern coast of Sumatra, 

 six to ten miles inland, in swamp waters 

 and ditches, is found that peculiar laby- 

 rinth fish, Luciocephalus pulcher. Liter- 

 ally translated the name means pretty 

 pike-head, and in appearance it does re- 

 semble that voracious game fish. 



The general color is attractive reddish- 

 brown, with a dark lateral band bordered

with black and white ; abdomen light 

 gray, with a tint of rose. As with other 

 labyrinth fishes the coloration is apt to 

 vary considerably. Full grown individ- 

 uals may reach a length of four inches. 

 Authentic information on its breeding 

 habits seems to be lacking, though an 

 opinion has been held that it is live-bear- 

 ing, which is unlikely. It is known to 

 aquarists only from a number of speci- 

 mens taken to Europe in 1905, wine'" 

 did not lone survive. 



About six hundred species of fishes 

 are found in the rivers of the United 

 States. 



The Greeks played an instrument called 

 a lyre. The instrument is still used, but 

 now it's a mouth-organ. — Harvard Lam-
