The stickleback is a small fish that inhabits the brackish waters from Cape Ann to New Jersey. Mr. Hornaday says that the abdomen of the male has been provided with a gland filled with a clear secretion which coagulates into threads when it comes in contact with the water. By means of this, a hood-like nest large enough for the female to enter is fastened to the vegetation at the bottom of the sea, and the eggs are deposited in the nest.
