1 oz. for 2000 plants or 100 ft. of drill; 
1 to 2 lbs. per acre 
CULTURE: It is not difficult to grow good head 
iettuce, but it is necessary to first have good seed of 
the proper variety and suited to your conditions. Also 
necessary is good soil and water so as to insure steady 
growth from the time the seeds are planted until the 
heads are ready to use. Unless the soil is rich, we 
recommend liberal amount of manure or commercial 
fertilizer. 
For large acreage, the most successful and best way 
is to plant 2 rows of beds 16 inches wide and 6 inches 
high with 24 inches between the beds for irrigation 
ditch or can be planted in single rows 20 inches apart. 
Two weeks after it comes up it is usually large enough 
to be thinned to single plants to a distance of at least 
14 inches. Keep crop clean of weeds at all times. Culti- 
vate thoroughly but not deep. Ground should not 
become dry but care must be used in irrigating.

20 THE WESTERN SEED COMPANY, DENVER, COLORADO © 
GREAT LAKES (SHIPPERS STRAIN). A recent 
development of Great Lakes with somewhat 
crinkled leaves. It is the best strain for average 
conditions, such as heat adversities. Selected 
for its resistance to tipburn and sunheat. Heads 
large, uniform, well-rounded, bright green color. 
NEW YORK PW 55. One of the surest heading . 
varieties and unusually resistant to tipburn and 
slime. It is the result of many years of selection. 
Both in summer and fall will produce a high 
percentage of beautiful hard, symmetrical, well- 
rounded heads of medium to large size when 
grown on good, fairly rich soil. 
NEW YORK 315. An excellent strain of New York 
for mountain, high altitude crops as it is a good 
header and slow to tipburn and bolt to seed. A 
rapid grower; heads large, well formed and slow 
to slime. At heading time it likes liberal amount 
of water. 
NEW YORK 199. An early variety; resistant to tip- 
burn. Heads medium large, compact, attractive. 
NEW YORK 12. An early variety; heads light 
green, rather flat. Now seldom used. 
‘ 
NEW YORK 515 IMPROVED. Similar to New York 
12 in habits and type of plant, but produces a 
larger percentage of marketable heads. Espe- 
cially suited for warm weather. 
IMPERIAL 815. A sturdy, robust strain selected 
from 847, One of the best strains for Colorado 
but must be grown with care as it is a tight 
header and if weather is hot may tipburn and 
slime. Will not stand long in the field when ready 
to harvest. We recommend at least 2 or 3 cut 
tings. Don't wait until the entire. crop has ma- 
tured. It produces a surprisingly high per cent 
of No. 1 heads which are large, solid and of fine 
appearance. Likes frequent and light waterings. 
Best suited for early summer and late fall crops. 
IMPERIAL 44. Heads medium large, slightly flat 
tened, compact, one of the best hot, dry weather 
varieties, used extensively in the East and in © 
Arizona for an early crop. Fd

IMPERIAL 615. A variety that does best in cool 
weather. Withstands frost and cold better than | 
other varieties, not especially recommended for © 
Colorado but does well in Arizona and California © 
during the winter months. 5 | 
IMPERIAL 847. Heads uniform, good size; solid and 
usually round. Does unusually well in cool wea- 
ther. ; | 
PROGRESS. A new variety crossed with Imperial — 
No. 44 which has proven very favorable and — 
fitted to western climatic conditions, but does not — 
meet adversities like Great Lakes. Produces | 
a high percentage of marketable heads which © 
are medium large, well formed, and not as rough — 
as Great Lakes. Leaves, thick, dark green, and — 
heavily curled.
