Mr. Editor:- It is really amusing to see the various and conflicting notions about the Delaware grape; but, depend upon it, it is nothing else but a North American native grape. Any one who is accustomed to see large collections of the foreign grape (vinifera) growing in the open air, (under glass they do not develop their characteristics,) will see at once that the home of the Delaware is in the Occident.

The grape-vine has been my hobby from my earliest childhood; and I have therefore always paid particular attention to it, not only in my native country, (Germany,) but also in France, Spain, Italy, and Switzerland, as also during my little stay (forty-two years) in Pennsylvania. Here I have cultivated, during the last thirty years, on a piece of ground one acre and a quarter in extent, and trenched throughout three feet deep, several hundred kinds, with the hope to find one variety at least that would suit our climate, but without success. I have one variety, which I imported with fifteen others from the Cape of Good Hope, which does tolerably well, only it is too late for the climate of Pennsylvania. Now among all these, and also those which I have seen abroad, there was not one that looked like the Delaware, or any other American grape; and if that vine in Frenchtown was imported, it does not prove, therefore, that it was a foreign variety. I have myself received by importation from the Baumanns, at Boll-viller, France, and Bronner, Germany, American grape-vines (Isabella and Major Long's) with foreign names.

But I believe that the Delaware grape may yet be found growing in its wild state somewhere on the Ohio, as Doctor Schoepf, (the botanist,) who travelled in the United States during the years of 1783-434, found a grape on the sandy shore of the Ohio River, near Pittsburgh, the description of which corresponds exactly with that of the Delaware grape.

The Catawba, which then was called the Cherokee grape, was cultivated, with many others, at Bartram's Garden, and the York Madeira he found wild near Baltimore.

One of your correspondents believes that the Delaware is a seedling of the Traminer, (of which I have cultivated four varieties, the Red, the Black, the White, and the Spice Traminer;) but that is not the case, as no seedling of the Vitis vinifera will do better in our climate than the parent of it has done in the open air, as I know from many years' repeated experience.

Another judges the Delaware wine "equal to Johannisberg." I am glad to hear it; he must be one of the favored ones if he has tasted true Johannisberger, as that article travels to the cellars of kings and princes exclusively. But to have an idea of the preciousness of that wine, we have only to take into consideration the price which is paid for it: for instance, the king of Prussia obtained a stueckfass, (a cask which holds about 250 gallons,) for which 12,500 florins were demanded, (twelve thousand five hundred florins.) The Riesling, of which that wine is made, is cultivated elsewhere in Germany, but no Johannisberger is produced. It is the favorable locality to the Rhine, with its warm and sheltered exposition, and the great care to press none but perfectly ripe and sound berries, which give that excellence to its wine.

One thing more, and I have done. I do not give this as something new, for there is nothing new under the sun; even the ringing of fruit-trees and grapevines was already practised by the ancient Romans, and later by the French and Germans, as also the renewal system, which was accurately described on the continent of Europe fifty years ago and longer.

[The above we esteem a valuable and interesting contribution to the " grape question." The opinion of a man who has made the grape a hobby from his earliest childhood, and who has travelled through the principal grape countries of the world, is entitled to more than a passing notice. The remarks in reference to the Catawba are of peculiar interest; we have other testimony tending the same way, which we shall lay before our readers in good time. We are obliged to you for the German catalogue; we find in it the Catawba, Isabella, York Madeira, and other familiar names. - Ed].
