Illustrated by Henry Bugbee Kane. "Pet goldfish that are turned out of their glass bowls into neighborhood pools retain their bright color but their descendants grow gradually darker in hue and in a few generations the offspring revert to the dull brownish or olive-drab color of the species as it was originally found in the wild. Those suburbanites who think to add a decorative touch to their estates by putting Goldfish in their garden pools often are surprised at the consequence, which is that the Belted Kinfisher comes regularly to poach and occasionally one of the heron tribe is found stalking solemnly about the pool in the process of stuffing itself with an fish dinner in glittering installments." Index and very brief bibliography.
