...le, so that the general shape would be like an hour-glass. Across the narrow part is to be stretched a screen of one-quarter inch wire cloth, which will confine the spawners to the deeper end of the pond, while the fry or hatching spawn will be kept separate. This form of pond is advantageous where for any reason only a few ponds can be built. Between all ponds that are connected they should be screened where water runs from one pond to the other, that is, at the inlet and outlets. Each pond should be surrounded by one-half inch wire mesh two feet high. This makes a protection to the ponds from enemies, and also keeps the Frogs confined to the ponds they are intended.   Care of Ponds. The accumulated decayed matter ought to be occasionally removed. The frequency of this depends on character of the water supply, the amount of silt it brings into the ponds, the character of the soil, and on the thoroughness of the yearly removal of the surplus vegetation. Care should be taken that the ponds do not become offensive with stagnant water and rotten vegetation. This condition is detrimental to large production; while abundant pond vegetation is favorable to a large production of fry it must not become decayed. It is sometimes so luxuriant that it settles down in a blanket-like mass and smothers and pens in many of the young Frogs. Under such conditions it should be removed frequently. This can be done by lowering the ponds, if they are built so they can be drawn off, which is a very desirable and convenient way if the topography of the land will permit. A strong flat-bottom boat should be made, in which can be taken the surplus matted vegetation and carried off. At each end of the boat a ring should be fastened, through which stakes can be driven to hold the boat at points in the pond to be worked. The vegetation is raked from the water in small lots. Care should be taken not to bring up any of the small Frogs and Tadpoles with the vegetation. It s...
