Crisp-Head 
Lettuce 
430z. per 100 Ft.; 3 lbs. per Acre 
tender and crisp when quickly 
grown and thus requires a well 
enriched soil, plenty of moisture, 
thorough cultivation and _ cool 
weather. A check in growth from 
lack of nourishment or moisture 
usually prevents heading. Let- 
tuce is quite hardy and can be 
planted outdoors on the ap- 
proach of Spring as soon as soil 
and weather conditions permit. 
Sow 1% in. deep in rows 18 ins. 
apart and thin out to stand 6 to 
10 ins. apart in the row. If the 
larger heads crowd, thin out 
again and use as required. After 
the plants have made some 
growth, a light application of 
fertilizer such as nitrate of soda 
will give that vigor necessary to prevent any check 
in growth. 
Lettuce seldom heads well in hot weather. It is 
best not to plant after May unless special care such 
as irrigation or artificial shading can be provided. 
For full use, sowing can again be made in August. 
BLACK SEEDED ICEBERG 
Bred to withstand Hot Weather 
83 Days—The popularity of this superior strain is 
increasing rapidly since the outstanding merit to 
withstand heat during warm weather has not been 
overlooked by the home or market gardener who has 
tried this variety. The plants are hardy, rugged and 
slow to bolt to seed. The thick leaves are well folded 
producing large frames with solid, hard, well formed 
heads, medium light green in color. Deliciously crisp 
and sweet in flavor. 
NEW YORK No. 12 
75 Days—An early sure heading strain of New York 
used in shipping and well known in all markets as 
the standard Iceberg type. It is well adapted to mid- 
season maturity resisting hot dry weather. Forms 
a solid cabbage-like head with medium light green 
leaves slightly curled on the edges. Seed white. 
ICEBERG

New York, which is commonly called Iceberg by pro- 
duce shippers and green grocers. A crisp heading 
late variety very desirable for home garden and for 
truckers serving local markets. It will not stand 
long distance shipping. Iceberg is large with wavy, 
fringed light green leaves tinged with brown at the 
edges. Heads compact, crumpled, white inside, crisp 
and sweet. Seed white.
