In the February number, it is rather assumed that the Betula excelsa and htea are distinct, but nearly similar species of birch. I had never doubted but that the excelsa of Willdenow, Acton, and Bigelow, is the lutea of Michaux, f.; and Bigelow, I observe, gives the lutea of Michaux as a synonym of the excelsa. A. W. C.

The New Rochelle Blackberry will not endure our winters here, unprotected; neither will the finest raspberries; I hare jut noted, as follows: -

Hudson River Antwerp Raspberry, not much injured; about a third of last year's growth killed.

Col. Wilder, slightly injured at ends of branches.

Brinckle's Orange, not much hurt.

Knevet's Giant, slightly injured; about as hardy as Col. Wilder.

Cushing, killed down to snow-line.

Vice-President, rather tender; killed more than half last year's growth.

Thunderer, nearly as hardy as the common Blackcap. This is a very strong grower, producing a good-sized, firm fruit, well adapted for market.

These varieties all need protection, but they.pay well for it.

Peaches, cherries, and plums, are in good order.

Tours, truly, Charles Beits.
