thick and short jointed; leaves large, dark green, deeply lobed; bunches 
medium to large, loose; stems long, giving bunch a drooping appearance; 
berry long, tapering at both ends, dark blue when fully ripened; flesh solid, 
skin thick; flavor good. Good shipper, and attractive, but can only be 
matured in localities where one can count on six months from frost to frost, 
later than Flame Tokay. 
Flame Tokay.—Vine a strong grower and a heavy bearer; canes strong, 
with long internodes or joints; leaves large, dark green, only moderately 
lobed; bunches large, often weighing five pounds or fnore, fairly compact, 
well shouldered; berry large, oblong with rather a flat tip with pistil scar 
persisting, rather a coppery red, with thin bloom; flesh solid and flavor very 
good. Fruit a good shipper and attractive. Colors best on rather light soil, 
fairly free from mildew and a desirable variety where the season is long 
enough. About thirty days later than Alexandria or (Muscat). 
Malaga.—This variety has been little grown in Colorado. It is a 
white grape maturing only a little later than the Alexandria. A good shipper 
and one of California’s favorite table grapes. California-grown Malagas are 
found on our markets at Christmas time. May be worthy of more thor¬ 
ough trial in’ Colorado. 
Peru (Rose of).—Black Malvoise, and Zinfandel have been planted. 
The last two are rather early and soft, split badly in damp weather and 
mould in shipment. The first is a fair variety, but neither of the three should 
be considered in a commercial vineyard. 
Sultanina (Thompson Seedless).—Vine strong grower and very prolific; 
canes thick, rather long jointed; bunches long and loose, often a foot long 
or longer, shouldered; berry small, oval, light yellow, transparent; flesh 
firm, skin thin, flavor sweet, seedless. Ships well, quite attractive, and 
would sell well in quantities. Can be easily dried and makes excellent 
raisins. Variety well adapted to the longer system of pruning. 
AMERICAN VARIETIES. 
Agawam.—Generally classed as a native grape, although some authori¬ 
ties place it as a hybrid between one of our native grapes and the foreign 
vinifera. A good red grape slightly earlier than.Concord. Has a rich musky 
flavor and is a good market grape. 
Concord.—This is the old standard native grape. It is a black grape 
of good quality. Vine a good grower and prolific. Ripens about with the 
Alexandria. 
Deleware.—This grape is quite commonly grown. It is a good early 
variety with a nice flavor. Bunch and berry small. A good bearer, color 
red. 
Moore (Early).—A good early black grape. 
Niagara.—A good white grape of good quality. A good bearer and 
sells very well. A late grape, requiring too long a season to be adapted to 
higher altitudes. Ripens about with Flame Tokay. 
Worden.—A variety a little earlier than the Concord. Berry slightly 
larger and softer. A black grape of good quality. A good one for home 
use or for market. 
INSECTS AND DISEASES. 
Insects.—Very few insects are troublesome to the grape grower in 
Colorado. Grasshoppers are about the only insect that has been 
reported as doing any serious damage. They generally migrate into the 
vineyard from a nearby field where their food has been cut or destroyed in 
some way, and often in such numbers as to do serious damage before their 
work can be checked. Early in the season it is possible to kill them by 
spraying the vines thoroughly with arsenate of lead. This is not always 
satisfactory, however, as the hoppers work a great deal near the center of 
the vines where it is difficult to apply spray, and they may do serious dam¬ 
age by girdling canes before they get a fatal dose of poison. Then it is 
objectionable to spray late in the season with such a poison. A good plan
