One of the advantages claimed for this corn by Professor Mapes, is that it may be kept green and fresh all the year round. The subscribers limited experience, however, does not enable him to endorse this. Addressj_post paid, ALFRED E. BEACH, White Plains, Westchester Co , N. Y. [Prof. Mapes, in the “ Working Farmer,“ 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 difference between the two. This year we sent to the fan: a stalk containing eight full and f ai* ears, and we could have sent many hundred stalks of six ears each.“ 20tf A RARE CHANCE FOR MAKING A HAND-SOME FORTUNE.—Any person wishing to take an interest in a very valuable patent right for the New England States, and having one or two thousand dollars capital (one that has already been in-troduced and pays two or three hundred percent.) will please address H.
