In obedience to a request made by the late editor of the Horticulturist, I submit a few specimens of a new plum, called Marten's Seedling, (from the fact of its having originated in the garden of a gentleman of that name.) I also enclose fruit of the Jefierson variety, in order that you may be enabled to judge comparatively of each in-dividual sort. I have fruited Marten's Seedling for the last five years, and most unhesitatingly pronounce it equal, and in some respects superior, to the best varieties at present in cultivation or generally known.

I annex the reasons for the superlative encomiums so freely bestowed upon it, and also to satisfy the sceptical that its merits are not exaggerated. In the first place, the fruit, when let hang until fully matured, it not surpassed in point of flavor by a Green Gage. Secondly - it is as productive as a Lombard or Red Gage. Lastly - it is exceedingly hardy, and a prodigious grower, not unfrequeutly realizing nine feet from the bud in a single season. It is also a remarkably early bearer. I have at present some eight or nine trees, but three years old, with crops of fine matured fruit. To this add the fact that it is capable of being propagated as rapidly as the apple or pear, (rarely losing ten per cent in budding,) and you have a fruit not easily beaten. C. Beagles.
