A New Jersey correspondent of the Rural New Yorker writes: My clear water carp pond covers an area of about three-fourths of an acre, and is located about eighty feet below springs in the hillside, which furnish a never-failing supply of pure, clear water. The normal temperature of these springs, where they empty into the pond, varies but little according to season, but maintains an average of fifty degrees, Fah. Several times through the summer I found the water in the pond indicated an average of 80 degrees, Fah. The pond is so constructed that the water is constantly drawn from the bottom, thus keeping the surface at this high temperature. About one-half the pond is covered with mud to the depth of two feet or more--an essential in all carp ponds for hibernating. A limited supply of pure German carp fingerlings to place in the pond was sent me by Prof. S. F. Baird, United States Commissioner of Fish and Fisheries, Washington, D. C., and placed therein on April 6th last. No food was given besides that which grew in the pond. I saw them at rare intervals during the summer, and was agreeably surprised, when I drew the pond November 16th last past, to find that they had grown to be sixteen inches in length, and a pair weighed eight pounds. * * * * * THE MONARCH LIGHTNING SAWING MACHINE.
