I did not intend to obtrude my thoughts again on the pages of the Horticulturist, as I very well know the great majority of its readers care very little, be it native or foreign. All they care to know is, Is it good? is it hardy? and does it succeed well without extra care?

These questions, however, it is needless for me to answer, as that has been done time and again from all sections of our country.

In reply to your "Buffalonian" correspondent, however, it seems meet that I should say a few words. He admits " that it appears the fact is established, that the Delaware grape was not found in a wild state in the localities visited by him, (me,) but still does not see the impossibility of its originating somewhere in the country!" I am perfectly willing to concede that it originated somewhere! that its place of origin, however, was not any where on " Uncle Sam's potato patch!" but that, in company with many others, it was brought across the "big pond!" If it had originated any where in the section of country where the advocates of its nativism so positively asserted "that they could show us at least twenty places where it was growing wild, as truly aboriginal as the rocks around it," why can't they show us at least one wild vine? I think we have already fully proved that such is not the fact. Then it remains for those who call it a native - a Labrusca, forsooth! - if they could do so, to show us where that somewhere is, where it grows wild.

That, they will say, "is more than they bargained for 1" So with the following remarks we drop the subject, at least till some more palpable proof of its nativism is brought forth than has yet appeared, or some new " mare's nest" is discovered where it was hatched!

Your humorous "incog." correspondent has no objection to me " dosing him with Delaware grapes ad libitum; the discussion of the subject on paper being somewhat less juicy," (dry as parchment,) " I shall not give him (me) the same liberty, but reserve the privilege of crying enough if I (he) see occasion." Hold on, MacDufF, and-!

Well, the best I can do under the circumstances is to say, if you, Mr. Editor, and unknown friend, will give me a call next September, 1 think I can promise you both a real old-fashioned allopathic "dose" of Delaware grapes, and a few others intermixed, for the sake of variety - and to prevent griping!

It is an old and trite saying, " that to convince a man against his will, he is of the same opinion still," which is truly verified by the many remarks published in relation to this grape.

In your. " note" to my article in the September number, you, Mr. Editor, call on me " to trace the Delaware to a time antecedent to the advent of any American grapes superior to Alexander." This I can easily do to the satisfaction of my own mind, but may not be so convincing to others.

A gentleman of undoubted veracity, and who has made extensive inquiries along the Delaware River, writes me that "There are persons yet living in Bucks County, Pennsylvania, who knew the Delaware grape in 1823!" This was several years anterior to the advent of either Catawba or Isabella. In the year 1823, Mr. John Adlum, of Washing., on, published " A Memoir on the Cultivation of the Vine in America," and does not even mention either Catawba or Isabella, though he gives a list of grapes in his vineyard at Georgetown, of twenty-two varieties, native and foreign; and yet Mr. Adlum is the person who first introduced into cultivation the Catawba! About the same time, or soon after, which must have been from the year 1825 to 1828, Mr. Prince, of Flushing, first advertised the Isabella.

A correspondent from Bucks County, Pennsylvania, writes me, " I feel sorry that Mr.-made that mistake in ' Gardener's Monthly; The Delaware, or, as it is called here, the i Ruff,' or the ' French wine grape,' is not a native grape; it is a true foreigner. Mr. Provost, of Frenchtown, New Jersey, imported it among a lot of other foreign grapes." My correspondent further says, " A Mr. Bergstrasser of New Jersey, who was a great fruit man, got the Delaware grape from Mr. Canoa, of New Jersey, and Mr. Canoa got it of Mr. Provost, and all the Delaware vines that are in the northern part of Bucks County came from the late Mr. Bergstrasser of New Jersey, who spread it extensively; but he had no name for it except the French wine grape, because Mr. Provost was a Frenchman. Then a Mr. Ruff also brought it from New Jersey, and having no name for it, people called it the 'Ruff grape,'." etc.

These authorities, if they prove any thing, certainly go pretty far toward making out a clear case / That the Delaware and the Ruff are identical, I have the proof before me, growing side by side; and that all the vines of this variety came originally from Mr. Provost's garden seems clear, he being a Frenchman, and known to import vines from France; and that the Delaware is one of them appears equally clear; and that so early as 1820 or 1823, it could not well have originated and borne fruit in his garden, and been scattered over New Jersey and Bucks County, Pennsylvania, either as a cross between native and foreign, nor yet as a true seedling of a foreign kind, because, as we stated before, "persons are yet living who knew it in 1823!" Indeed, it is doubtful if Mr. Provost would plant any native grape, at least until by sad experience most of his foreign vines failed.

I have no more interest in proving it a foreign grape than my worthy opponent says he has in proving it a native grape, and am quite as anxious as he, or any other person can be, " to claim all the good things for America /" Still I am always willing "to render unto Caesar the things which are Caesar's," &C.

I think, Mr. Editor, you will concede that we have now traced the Delaware grape "to a time antecedent to the advent of any American grape superior to the Alexander," and also that it can be neither an American seedling, nor yet a cross between native and foreign, but a true imported Vitis vinifera.

[We agree with you, Doctor, that the questions in regard to the quality, hardiness, and productiveness of the Delaware have been pretty well answered from all sections of the country, and we hope all are now satisfied on these points; but do you not see what the settlement of these three questions involves? We leave "A Buffalonian" to take care of himself; but we want to be on hand when the "dosing" with Delaware grapes comes off; "and to prevent griping" - of course something of that kind will be .good; we understand, and will come. We do not think you have proved your point, Doctor; for it is easy to trace the Isabella back to 1810 at least, and we think we can go back of 1822 for the Catawba. We are sifting the testimony, and you and the rest of our readers shall soon have the benefit of our investigations in that quarter. We do not, however, now lay any special stress on this point, aside from its historical interest, as we think the question must be mainly decided by internal evidence alone. We are somewhat distrustful of that kind of testimony which runs back by decades, of which we can give you some amusing examples. But possess yourself in patience, and we shall soon have this whole question settled, one way or the other.

It can not, however, be done in a "note." - Ed].
