Charles H. Townsend has been director, and there have been many changes

made, notable improvements in lighting and ventilation, and the introduction of a large storage tank for pure sea water, as the impure, somewhat brackish harbor water, pvimped through a well, was unfit for many of the fishes.

blanda (possibly Var. pahistriformis), the little Sweet White Violet, found almost every where in damp places in our woods. Last summer we found them growing abundantly under water in a swamp. We took a number of specimens home and planted them in our aquaria where they still thrive. They seem to enjoy their gravel bed under water and form neat little colonies which give the tank an unusually attractive appearance. The plants retain a dark green color rivaling that of the giant Sagittaria. Its identity in the aqviarium will deceive many an expert botanist.

THE

mouthbreeders, Paratilapia multicolor, belong to the fish family called Cichlids. They are found wild in ponds near Alexandria, Egypt, and were first introduced into Europe as an aquarium fish at the beginning of this century. Their size is about two to two and a half inches long. The female is more heavily built than the male in the fore part of the body, especially back of the head, where the breeding bag is located. In this bag first the eggs,

and later, when hatched, the young mouthbreeders are kept. The color of the male of this species is very beautiful, especially at the breeding time. The body,

male must be removed from the aquarium where his mate is confined, otherwise he will disturb her in her work of caring for eggs and young. It is not advisable to let the fishes breed more than twice in a season or it will weaken them, especially the female, on account of the fasting while the eggs are in her mouth. These fishes are generally kept by fanciers, not alone for their beauty of color, but also for their highly interest-

this

answer requires an explanation, but in itself is intended to convey two facts; that the range of acceptable food tor goldfish is very large; that the subject is not of as much importance as supposed. A gentleman who has been a practical aquarist and a leading authority for a quarter of a century told me that he feeds his fish almost anything from the kitchen or table which is not too greasy, including cake! His fish are in large, shallow indoor tanks in which there is a profusion of healthy plant life, and an abundance of water. In a household aquarium of the ordinary type this haphazard method would not do, but nevertheless it is still true that if an aquarium is right, the fish may be fed on anyone or all of a score of foods, particularly
