LETTUCE 
CULTURE—One ounce will sow 150 feet or drill, two pounds 
an acre. Lettuce is a hardy plant and will stand a low degree 
of temperature; however, a moderate temperature is desirable 
during the growing period. Lettuce stands cold much better 
than heat, making it impossible to produce lettuce of good 
quality during the hot summer months. Hot weather causes 
the plants to go to seed instead of heading. 
Lettuce required considerable soil moisture; however, an

LETTUCE, GREAT LAKES 
GREAT LAKES—Bronze Medal award for 1944. This is of the 
Imperial type which is so largely used by truck gardeners. 
What chiefly distinguishes Great Lakes from other varieties 
of the Imperial type is its increased resistance to tip-burn 
injury and greater ability to produce solid heads under 
adverse conditions. The leaves are large, relatively thick, 
folding well over the head so that when unwrapped they 
give large pieces desirable for salads. 
We offer four strains for this season. 
Strain No. 428—This strain is about ten days earlier than the 
Standard, very uniform in maturity; adapted for early 
spring or late fall. Small rib, excellent strain for shipping. 
Postpaid (Pkt. 25c) (Oz. 75c) (14 Ib. $2.00) (Ib. $7.50). 
Strain No. 407—This strain was developed primarily to stand 
the heat, it has large protective wrapper leaves, fine cut 
edge. Matures about a week later than No. 428. 
Postpaid (Pkt. 25c) (Oz. 75c) (44 Ib. $2.00) (Ib. $7.50).

selected for earliness, smoothness, lack of ribbiness and uni- 
formity of heading. It is 7 to 10 days earlier than regular 
Great Lakes.

excess of moisture may cause stem rot. A light, loamy soil, 
enriched with well-rotted manure, is best adapted for the 
successful growing of lettuce. If planted on poor soil the heads 
will be small and leaves tough. 
As soon as the ground can be successfully worked, sow in 
drills 15 to 20 inches apart, one-half to one inch deep. Thin 
the plants 8 to 15 inches apart in the row. Large headed vari- 
eties, like New York Wonderful or Iceberg, thin to 15 inches 
in the row.
