In the Horticulturist for April you publish an article from your correspondent, C. G. Scrivers, of Cincinnatth on the Gen. Hand Plum. After reading your former notice, (with a drawing attached,) I discovered that you had fallen into an error when you supposed that it originated with Mr. Sinclair of Md., and had written out an article on the subject, but being very busy, had neglected to send you a copy previous to the publication alluded to above.

Tour correspondent gives the true origin, etc, of this plum, as I received it from Mr. Samuel Carpenter, of Lancaster, Ohio, and the notice I first sent you from Ohio in relation to the Gen. Hand Plum, its bearing qualities, size, etc, was predicated upon a tree upon the lot of Mr. S. Carpenter, grown from one of the grafts received from his brother in Penn.

In relation to the Montgomery Plum, I have only to say, that I have as repeatedly seen the fruit and eaten of it, as I have the Gen. Hand, and it is all your correspondent says about it, only that it is called the Montgomery Prune, instead of plum, by Mr. Carpenter.

There is another plum grown by Mr. C. which he ranked, I believe, as superior to either the above, and which he called the "Ground-acre." It is not so large as either the above, but I believe superior in flavor. I have a few trees of each of these plums, brought with me from Ohio, and thinking you would like to test the Mongomery Prune, I have sent you this day a scion of the same. The Ground-acre is far too advanced to cut you a scion for grafting this spring.

If the above is of any service to you, use it as you deem proper. I always think that we cannot have too much light on any new fruit, and I could have given you all the information in relation to these plums when I first noticed the Gen. Hand Plum, as well as now, if I had then felt its importance equally as much.

As soon as the busy season is over I will notice the "Primate" apple. or as it in dubbed by

I regret for the cause of pomology, that men should pick up a fruit and suppose it a seedling at once, and dub it with a new title, and send it forth, saying it must be a seedling, because Messrs. Thomas and Barry do not know it. A sage conclusion truly, showing how easily and upon how trifling a foundation a man will form an opinion, and then promulgate the same, for although Mr. Barry did not know the fruit, it is growing within a very short distance of Rochester. We have names enough for apples if the original ones could be kept sacred, and not re-christened so often.

It is this that creates such confusion in Pomology, and against which we cannot guard too much, and with you I will war continually to suppress it.

We have a seedling Tea Rose raised by myself, light straw with deeper centre, exquisitely fragant, large size, and full double, much like Lamarque, but more compact. It is an acquisition. I will send you a plant after a while, and will leave the opinion of its merits to your unbiassed judgment. A. Fahnestock. Syracuse, April 14,1851.
