Lettuce 
Lettuce, a native of Asia, has been under 
cultivation since remote ages. Introduced into 
England in the 16th century, its culture has 
spread among advanced nations the world 
over. Because of high vitamin content and 
addition of bulk to a balanced diet, its use 
is increasing widely in this country. 
Lettuce presents no particular problem in 
its culture and thrives on any fertile soil. 
Succession planting insures an abundant sup- 
ply during the entire season. For a very early 
crop sow in flats or cold frames about a month 
before planting outdoors. As soon as the soil 
is ready transplant in rows 18 inches apart, 
spacing the plants 15 inches apart. For later 
crops the seed is sown directly in rows and 
covered a quarter to a half inch deep. Plants 
develop better if the young plants at fourth 
leaf stage are thinned to stand 12 to 15 
inches apart in a row. As plants are thinned 
they may be set out in another row. As to 
rate of direct seeding, 2 ounces will sow 150 
feet of row or 3% to 4 pounds to the acre. 
One-fourth pound is sufficient to produce 
plants for an acre. There are 16,000 seeds in 
an ounce. 
Heading Varieties 
BIBB, BLACK SEED (60 days)—In Bibb 
we have a distinct early butterhead type let- 
tuce with thick, tender leaves. The outer 
leaves are a dark green, the interior a golden 
yellow color. For the best quality and flavor 
harvest before heads develop solid. 
BIG BOSTON or TROCADERO, WHITE 
SEED (75 days)—The heads are of medium 
size and compact. A butterhead type shows 
with a reddish tinge on the margins of the 
smooth glossy leaves and the heart develops 
a creamy yellow. 
GREAT LAKES, WHITE SEED (80 days) 
—A prime favorite among the solid-headed 
varieties, it is slow to bolt and remains sweet 
a long season. The glossy, dark green leaves 
are well folded with heavy ribs. Widely adapt- 
ed to commercial and home garden uses.
