Sir: - During the week ending with this date, we have received the additional exhibits. Miss Anna Gillingham, 1510 Poplar street, Philadelphia, 12 early " Newington " Nectarines. Nectarines are now so rarely seen from open air trees, and these were of such excellent size and flavor, that we especially commend them. A. B. Colgrove, Middletown, Connecticut, a large quantity of seedling pears, five kinds, but mixed together so that the kinds could not be separated. They were good fruit, but not equal to other named and well-known kinds of the season.

H. S. Cochran, Cecilton, Md., " Reeve Favorite " peach - five specimens of this popular Delaware variety, 9 inches in circumference.

W. F. Bassett, Hammonton, N. J., Bassett's American Plum. The improved native plums have been recently derived from the native plum of the North-Eastern States, but whether from the beach plum or the common red plum is not quite clear. The fruit is of medium size, good flavor for an American plum, and, as exhibited by a branch with fruit on, apparently abundant. In addition to these the Fruit Growers' Association of Ontario, the State of Connecticut, and the Potomac Fruit Growers' Association, have placed on the tables a large portion of a very large exhibit, but as they are intended for the special exhibit to be in order next week, we refer to them here only for the purpose of fixing the week of their appearance here.
