With specimens of an unusually dark green Norway Maple, we have the following from a correspondent at Old Westbury, N. Y.:"I enclose a few leaves from a Maple, which is different from any variety I have seen. It came in a lot of imported trees, is symmetrical, and resembles in its growth a Norway, for which it was purchased, and the bark is darker. About ten feet high, three-quarters of an inch in diameter, leaves dark, shining green, like a gooseberry, and is very pretty. Bark smooth, not like English Maple in any way. As thee is acquainted with more kinds than I am, I hope thee can give its name".
