They were first grown in the garden of Mr. J. S. Needham, West Danvers, and seem to possess some remarkable characteristics which eminently entitle them to general cultivation. The first specimens of this new species were exhibited in Boston the last season, and were pronounced by competent judges, a curiosity, as well as a most palatable fruit; in which opinion I think you will fully concur. The original plant was discovered growing wild in the midst of a blackberry patch in the State of Maine; and this year, for the first time, it has fully demonstrated what it is capable of producing under garden cultivation. It is a tall, upright bush, growing to the height of four and five feet, and is prolific to an extent scarcely credible to one who has not seen it in bearing. The bush from which these, which I send you, were picked, produced eleven quart* of marketable berries! The size as well as the quantity of the fruit would doubtless have been larger, if nearly half of the fruit had not been removed in the spring in separating the shoots from the parent stock, for the purpose of propagation. Besides being a great bearer the plant is hardy and needs no artificial protection during the winter.

The flavor of the high blackberry is well Known to be greatly superior to the common low blackberry; yet every cultivator is aware that, except in some favorable localities, the high blackberry is a shy and capricious bearer, and unworthy of his attention. When brought under garden cultivation that plant grows rank; but the few berries which it bears are ill-formed, hard and bitter. All these objections this new species obviates, and promises to bring their delectable fruit into general cultivation.

Mr. Needham has in his possession the original plant, and all that have been propagated from it; and in the spring he hopes to be able to supply demands for them from abroad. A visit to Mr. Ncedham's garden would richly compensate one curious in such matters, for his trouble. The cold weather of the past week has given some of the specimens I send a darker color than naturally belongs to them. The berry is usually as light colored and transparent as a sweet-water grape. - [Boston Journal
