Swamp lands, on a farm, converted into Froggeries, _bring in large profits_. If you have a piece of ground which is swampy, which can be found on most any farm, and you do not convert this into "_Raising Frogs_," you are losing one of the most profitable products of your farm, as _more money_ can be made from an _acre of swamp land in a Froggery than ten acres in wheat_, if properly managed, and with little expense. You first want to excavate a portion of it where you can have water, 50 x 15 feet, and another part of it 15 x 20 feet, and fence it in, as explained above with a 2-foot one-half mesh wire. In the larger pond place the breeding Frogs, and in the smaller one hatch out the spawn, and when they are developed into Frogs turn them loose on the swamp to grow until they maintain marketable size. If there is a small stream or ditch running through the swamp, which very often is the case, then it is an easy task. And here is where the old saying can be applied, "Makes money for you while you sleep." And good, big money it makes, too. _Don't put off_ turning your swamp into a _money-maker_. DO IT NOW. The Edible Frog (Rana Esculenta.) [Illustration: THE FEMALE FROG.] Two species of Rana are common in America and Europe, viz., _Rana esculenta_ and _Rana temporaria_. The latter alone is indigenous to Great Britain, and varieties of it extend throughout temperate Europe and Asia to Japan, and one variety (_pretiosa_) exists in the United States. The edible Frog (_Rana esculenta_), however, has been introduced into England. An Indian species (_Rana breviceps_) and several South African species burrow in the ground. ECOLOGY AND HABITS. The skin of Frogs is usually smooth and free from warts or horny excrescences. It is invested with a colorless epidermis, which is shed from time to time as the creature grows; this splits along the back and thighs, is worked over the head like the taking off of a shirt, and usually eaten by the wearer. The deeper layers contain much pigment, in cells which are more or less under muscular control, enabling Frogs to change their hue to conform to the background. Frogs are carnivorous, and in the season of activity are likely to be very voracious. The terrestrial and arboreal forms feed mainly on insects, worms, etc. The aquatic kinds also catch insects, but subsist more on aquatic animals--worms, tadpoles, small fishes, and other Frogs. These are seized and slowly swallowed, often, where before the remainder, perhaps still alive, has been got within the mouth.
