The growers of this region are organized into selling associations so that estimates of acreage and yields are obtainable. At present writing, 1918, there are in this belt in New York about 35,000 acres of grapes; in Pennsylvania and Ohio, about 15,000 acres, much the greater part of which is in Pennsylvania. The average yield of grapes to the acre for the region is about two tons. The average total production for the past five years has been about 100,000 tons, of which 65,000 tons are shipped as table-grapes, and 35,000 tons are used in the manufacture of wine and grape-juice. Among varieties, Concord reigns supreme in the Chautauqua belt. The writer, in 1906, made a canvass of the region, vineyard by vineyard, and found that 90 per cent of the acreage of the belt was set to Concord, 3 per cent to Niagara, 2 per cent to Worden and the remaining 5 per cent to a dozen or more varieties of which Moore Early and Delaware led. The manufacture of grape-juice on a commercial scale began in the Chautauqua belt and most of this product is still produced in the region. Here, only Concord grapes of the best quality are used for grape-juice. The growth of this industry is most significant for the future of grape-growing in the region. Twenty years ago grape-juice was a negligible factor in the grape industry of this region; at present, the annual output is in the neighborhood of 4,000,000 gallons. Grape-juice-makers now determine the price of grapes for the region, and while the quantity used is less than that for table-grapes, the time is not distant when it will be greater. _The Niagara region._ Fifty miles due north of the Chautauqua belt, across the end of Lake Erie and the narrow isthmus of Niagara, is a smaller belt on the southern shore of Lake Ontario so similar in soil, climate and topography that in these respects the two regions might be considered as identical. This is the Niagara region, Canada's chief grape-producing area. It is bounded on the north by Lake Ontario; on the south, at a distance of one to three miles by the high Niagara escarpment; to the east it crosses the Niagara River into New York; and in the west tapers to a point at Hamilton on the westward extremity of Lake Ontario. Here, again, is the influence of climate distinctly manifested. As this belt passes into New York, it widens and the influence of Lake Ontario is less and less felt to the eastward, and in consequence grape-growing becomes less and less profitable.
