Mr. Knox of Pittsburg has been testing a number of varieties, of which three have given entire satisfaction, viz.: Concord, Delaware, and Hartford Prolific. The Concord and Hartford Prolific are entirely free from disease in the vine and in the fruit also, while they ripen their fruit early and well. The Delaware is a very superior grape, and ripens in Pittsburg by the 6th of September, and is a very superior wine grape without the addition of sugar to its mice. Concord generally ripens its fruit well, and is probably destined to be the great grape of this country. Hartford Prolific ripens its fruit by the 1st of September; but although the grapes readily sell for twenty-five cents per pound, he would not plant it very largely, as the fruit has a tendency, under some circumstances, to drop from the bunch. Had found that the Catawba produced much more abundantly if laid down and whole vine covered with earth each winter. The Concord vine stands more hard usage than any grape that I know of, but repays well for good cultivation. The vine bears early and abundant crops of the most beautiful grapes that I know of Adopts the renewal system, planting a thousand vines to the acre, and training upon trellis eight feet high.

Obtains twenty-fire pounds of grapes from each vine after the third year.

Dr. II. II. Farley, of Union Springs, finds Diana to be one of our most valuable hardy grapes, and it is his decided favorite. Delaware does not suffer at all from mildew, and we think a great deal of it. Concord will prove our most valuable native grape, the vine being as hardy as an oak, and not killed by cold nor variable weather. Isabella has proved valuable for vineyard purposes, but of late years has been winter-injured. Catawba can not be ripened to perfection in Western New York. The renewal system of pruning and trimming is unquestionably the correct one, as all vines bear their best fruit from young wood.

Mr. Langworthy spoke of Delaware, Concord, Diana, Hartford Prolific, Union Village, and Rebecca, as the best six for family use, and Clinton and Delaware as the best two for vineyard purposes in this climate.

In answer to several questions, Dr. Farley stated his vineyard to be high and dry land, originally poor and clayey, with the subsoil all clay. He plowed it from eighteen to twenty inches deep, by using three teams; then underdrained it all, and the tile discharge water now. Then applied muck in its crude state pretty freely, plowing it in; and planted the vines upon the land thus prepared.
