Ooe of the advantages claimed for this corn by Professor Mapes, is that it may be kept green and fresh all the year round. The subscriber's limited experience, however, does not enable him to endorse this. Address, post paid. ALFRED E. BEACH, White Plains, Westchester Co , N. Y. [Prof, Mapes, in the " Working Parmer," December, 1851, gives the following directions for preserving the Stowell Evergreen Sweet Corn:— "The ears should be gathered when fully ripe, and the husk should be tied at the nose (silk end), to prevent drying, when the corn will keep soft, white and plump for more than a year, if in a dry and cool place. At the dinner of the Managers of the fair of the American Institute, last year, we presented them with this corn of two successive years' growth, boiled, and there was no perceptible diifference between the two. Thisyear we sent to the fair a stalk containing eight full and fair ears, and we could have sent many hundred stalks of six ears each." . 20 tf STEAM ENGINES FOR SALE—We offer for sale two Engines and Boilers, as follows : one 8 horse, horizontal, cylinder 7 inches bore, 10 inch stroke, on a cast-iron bed, fly wheel, driving pulley, governor, pump, pipes, etc. j has never been used.
