But I shall not permit this point to be determined by a mere assertion, though the record proves its correctness. Mr. P. complains that I have not quoted from some of his letters. To maintain ray position and refute his, it is not necessary to draw upon all his epistles; but to gratify him I will venture upon an additional quotation or two. In a letter dated June 10, 1859, he takes me to task for having, as he alleged, sent him, in the fall of 185V, one dozen vines purporting to be Delaware, which had proved spurious. How the error referred to occurred, is explained in his last article. In that letter, in endeavoring to rebut my positive denial that spurious vines had reached him through me, he says': "The specimen vine from you and the one I had layered all have entire leaves, and all from Dr. Grant and others have divided leaves"and continues: "Let me know whether your vines have divided leaves. Both vines are true natives, in spite of what my friend Dr. J. B. Garber says to the contrary" Thus it will be seen, that no longer ago than June, 1859, Mr. Prince was as well satisfied that the Delaware is a "true, native" as he was in November, 1855, when he declared he did not "think" it was, but" knew" it to be such.

This extract, I think it will be admitted, totally upsets his pretense that he was led to err in judgment and express an erroneous opinion in consequence of confounding the Delaware and the Ramsdell. His first positive assertion, that he knew it to be a native, was not the result of the error referred to, because the error did not occur till two years after the assertion was made; and had it really been so, the more recent and equally positive declaration that both the Delaware and the Ramsdell "are true natives" would dispose,of the first and conclusively settle that point. Our friend is clearly at fault as regards this matter; the facts are against him, hence his position is utterly untenable; and the best and only consistent course left for him to pursue is to gracefully back down, acknowledge his error, and, if he still deems it prudent or profitable to adhere to his present position of antagonism to the Delaware, find some other explanation than the one offered for the inconsistency of his conduct.

Mr. P. is any thing but tolerant toward those who declare their belief that the Delaware is an indigenous vine. In a letter dated February 6, 1860, he says:• "If any man is to be found so bold as to take the simple primary position that the Delaware possesses the various characteristics of an indigenous grape, which I believe no one has yet fully dared to do - although it forms the actual starting point - he would by this one act prove himself to be utterly ignorant and most remarkably stupid." And again, in a letter dated September 18, 1860: " If I had a child that could not distinguish quickly its foreign origin, 1 would not bring him up." I leave it for Mr. P. to reconcile these declarations with those quoted, and will simply remark, that had the same rule in bringing up children been applied to him that he proposes applying to his children, he (W. R. P.) would now, if engaged in demolishing the Delaware, have to transmit his hostile missives from spirit-land rather than invite them on this mundane sphere.

When Mr. P. was in Delaware, after returning from our visit to Mr. Campbell's garden, I introduced him to Hon. C. Sweetser, in front of the hotel, within half an hour of the departure of the train on which he left, and went to my office. I was not aware, till he so stated in his article, that he embraced that brief interval to visit the garden of Mr. S. This garden is the most thoroughly protected of any in the place, there being high brick walls on the west, north, and east sides. Mr. S. had at the time but a single Delaware vine on his premises, and that but a small one, hardly large enough to have fruit, and Mr. Prince saw no vine of any kind in that garden that was not protected by being trained against a south or east brick wall. His visit to this garden, therefore, does not in the least aid him in making out his case, or conflict with or weaken any statement made in my first article.

The point as to whether he saw one or three vines at Mr. Campbell's, trained against the south and north walls of his house, and which were in fruit at the time, is of little importance. If it were of any consequence, a personal examination, or the testimony of Mr. C, or of his lady, who in his absence picked the fruit for us, if called for, would show there are three vines - two on the south side, one on the west. Such is the case now - such was the state of affairs then.

The intimation by Mr. P., that I have named a "foreign vine" the "Delaware, in order to impress the public with the belief that it originated" here, is wholly gratuitous, and entirely uncalled for, and, I am constrained to add, unworthy any gentleman as well informed on that point as he must be. It demands notice at my hands, and none the less so because of its being accompanied by a professed disclaimer of intended offense. In introducing the Delaware to notice before the Ohio Pomological Society, in the fall of 1851; in an article published in the Ohio Cultivator in 1852; in a communication in the Horticulturist for November, 1855; and in a letter to the editor of Hovey's Magazine of Horticulture, and published in the number of that work for November, 1855; and, I believe, in all my subsequent communications, I stated clearly and explicitly where the vine came from, and how it got here. I never wrote a line or uttered a sentence to mortal man that would warrant even an inference that I supposed it originated here. All this is pure and unadulterated fiction, utterly void of foundation in fact. Neither did I name it "Delaware" as intimated.

It was brought to notice here, had no name, and all efforts to have its identity fixed having been unsuccessful, it acquired the appellation complained of by common consent and usage, in reference to the place from which it was disseminated, without any agency of mine, or that of any other particular person, so far as my knowledge extends.

It is not "notorious," nor is it even true, that " Joseph Heath, living just out of town, brought the first vine there [here] from Bordentown." It is, however, true, that Richard Warford, living some six miles from town, in the year 1841, brought from Frenchtown, N. J., for his neighbor, Benjamin Heath, the first two vines, one of which Mr. W. received for his trouble, ana the other was planted by Mr. Heath. Both are still flourishing, though growing in a thoroughly exposed situation; and from these two vines originated ail the genuine ' Delawares " that have been disseminated from this locality. These are notorious facts - matters of record, with which intelligent horticulturists are familiar, and I should not have again adverted to them but for the ungenerous innuendoes indulged in by Mr. P.

I have recently been informed that a distinguished Cincinnati horticulturist has had a number of Delaware seedlings fruit, and the result is such an unmis-takable tendency toward the Fox grape as to pretty clearly indicate a close relationship to that family. This would certainly indicate native origin; and facts that have come under my own observation are strongly corroborative. Two years since I purchased of Mr. Heath two seedling vines, which he assured me were beyond the possibility of mistake from the seed of the Delaware. It was in the fall after the foliage had fallen, and the wood had a very close resemblance to that of the Delaware. Neither has yet fruited, but though clearly distinct from each other, the leaves of each are decidedly foxy. If the Delaware is, as Mr. P. and those who agree with him contend, really an exotic variety, why is it they can not tell what foreign variety it is? It is a fruit that certainly would be deemed worthy of "a local habitation and a name" in any country; and hence there should be no difficulty in fixing its identity; and to do so is clearly incumbent on these gentlemen.

I believe I am not mistaken in saying that Mr. P. now claims it is the Traminer. If so, it has certainly undergone a remarkable change since it left its native country, and it is strange and unaccountable that recent importations do not show any aptitude for a similar metamorphosis, but persistently follow in the wake of all other foreign vines thns far tested. The position of Mr. P. is beset with numerous and formidable difficulties, which must be overcome before he can hope to make much headway in his present undertaking. Not one of those difficulties has he yet succeeded in disposing of; they all still stare him squarely in the face, and most effectually block up his pathway.

[Mr. Thomson has presented his points so clearly and comprehensively, that Mr. Prince will now have no difficulty in comprehending the precise* issue between himself and Mr. T. This will save a great deal of unnecessary circumlocution. - Ed].
