life to man. What tremendous viticultural possibilities, therefore, lie in 
store for the United States, which, so far as is known, has more native 
species within her confines than all the rest of the world. Considering her 
native species and that the vinifera also finds congenial conditions in this 
country, we should rapidly develop a great viticultural industry, makef 
choicer wines and raisins and other products, and a larger and finer assort- 
ment of them than any other country. In fact, tyiis country has already 
developed three broad, distinctive viticultural regions: 
1. A region in which improved varieties of the more northern native 
species and hybrids of them and other species are grown for table, wine, 
unfermented juice, and other purposes. This irregularly covers the entire 
United States from the Atlantic Coast to the Rocky Mountains. Of late 
years, quite a few plantings have also been made in parts of Oregon and 
Washington, the industry being most extensive in the states west of the 
Hudson and north of the Ohio River and that border on the Great Lakes, 
and in the Central Mississippi Valley States. The sparkling wines and un- 
fermented juice produced from them are rapidly establishing a reputation 
for themselves. 
2. The Muscadine region of the South Atlantic and Gulf States. This 
includes the entire southeastern Coastal Plain, reaching well up into the 
Blue Ridge Mountains and Gulf Coast States and extending from the Potomac 
to Florida, thence to the Rio Grande River, and thence extending along the 
Mississippi into the Great Central Plains to southeastern Missouri and the 
Tennessee River. In this region, improved varieties of the rotimdifolia and 
munsoniana species are grown for various purposes. These grapes are 
relished when eaten in a fresh state. They make excellent preserves, and 
wines from them find admirers. 
3. The vinifera region, in which vinifera varieties are grown for all 
the various purposes. This is located almost entirely west of the Rocky 
Mountains and so much of it in California that it might be called a California 
industry. Nearly 100% of the raisins and grape brandies produced in this 
country, and at least 75% of the entire grape output of the country, come 
from California. 
Department Researches. 
The U. S. Department of Agriculture, through its Viticultural Investiga- 
tions, is endeavoring to make itself useful in a broad way in assisting in the 
proper development of the industry of the entire country. 
These researches are demonstrating in the Eastern States that the 
failures made by the grape growers in the past were mostly due to lack of 
knowledge; that the causes of the failures were specific; and that these 
can now be overcome, thus encouraging them to again become interested in 
planting vineyards. The investigations are assisting in the reestablishing 
of what was formerly a pretty extensive grape industry in the American native 
grape regions. This had been gradually declining for years on account of 
failure to apply the proper cultural, training, pruning, and spraying methods, 
to overcome the prevalence of grape diseases and insect pests. The growers’ 
lack of experience and knowledge as to the best means of counteracting 
and eradicating such evils has been supplied in part and a vast change is
