LETTUCE for ool Crisp Salada 
Great Lakes 
MAY KING. W.S. 63 days. Cabbage- 
butterhead; medium small, light green, 
tinged slightly at edges with brown. It 
is early and especially good for out- 
door culture. 
Pkt., 10c; 14 0z., 20c; 0z., 30c. 
PENNLAKE. A cross between Great 
Lakes and Imperial No. 847. A very 
fine uniform head with a dark green 
color. Quality excellent. 82 days. 
Pkt., 10c; 144 0z., 40c; oz., 75c. 
PROGRESS. A new crisp heading let- 
tuce in the Imperial class; developed 
by the U.S.D.A. in co-operation with 
the New Jersey station. It is an early, 
dark green, thick-leaved, heavily sa- 
voyed, tip-burn resistant, crisphead 
lettuce, of good flavor and high qual- 
ity. As compared with Imperial 44, 
Progress is a darker green, thicker 
leaved, more savoyed; heads are more 
dense, more resistant to tip-burn, and 
of superior quality. 
An ounce will produce from 3000 to 4000 plants. 
Lettuce thrives on nearly all soils, but because the growth 
should at all times be rapid to insure crispness and best flavor, 
the soil should be heavily enriched and well worked before 
planting. Lettuce being quite hardy, seed may generally be 
sown as soon as ground can be fitted, as while prolonged or con- 
tinued freezing will kill the plants, they are but little injured 
by an ordinary frost. Seed may also be sown in hotbed in gentle 
heat, and the plants, if well hardened by having been often ex- 
posed to the air, may usually be set in the open ground very 
soon after the time suggested for sowing outdoors. 
OAK LEAF. A loose leaf variety, fine for the home garden and 
of high quality. Very tender leaves; fine for growing in hot 
weather. Pkt., 10c; 4 02., 25c; oz., 45c. 
BLACK-SEEDED SIMPSON. Much larger than the preceding, 
but not so much curled. Forms a large, loose cluster of leaves 
rather than a head; leaves light yellowish green. 
Pkt., 10c; 144 02z., 20c; oz., 30c. 
xBLACK-SEEDED TENNISBALL. More extensively grown in 
New England than any other variety both for first outdoor crop 
and for main crop, the medium sized heads being the size most 
liked by gardeners, while its compact form allows it to be grown 
more closely together than others. 
Pkt., 10c; 144 oz., 20c; 0z., 30c; %4 1b., 65c. 
CRISP AS ICE. A midsummer variety, surpassing all of this class 
in crispness, tenderness and fine flavor.

BIG BOSTON WHITE SEEDED. Probably the most generally 
used in cultivation. It is a cabbage-head, butter type, medium 
large, finely shaped, globular, medium light green with slight 
tinge of brown on margins of outer leaves. 
Pkt., 10c; 14 0z., 20c; 02z., 30c; % lhb., 65c.

% l1b., 65c. 
GRAND RAPIDS. One of the easiest 
varieties of lettuce to grow. It forms 
no head but produces an abundant 
crop of pale green leaves, slightly but 
closely crumpled, which have an ex- 
cellent flavor. Pkt., 10c; 
YQ OZ, 20c; oz., 30c; %4 lb., 65c. 
GREAT LAKES. 82 days. Bronze Medal, 
1944. The finest Iceberg yet! Superb, 
crisp heads even during the hot, dry 
weather of midsummer. The crinkled 
dark green leaves fold inward, blanch- 
ing the heads to a cool, crisp white- 
Grand Rapids ness. Pkt., 10c; 4% 02z., 35c.

IMPERIAL No. 847. (Long Standing Iceberg.) This fine 
lettuce will do well in spring and fall, and is outstanding 
as a summer heading variety, even during hot weather 
most every plant will produce a fine solid head.
