THE GRAND JUNCTION SEED CO., Grand Junction, Colorado 
Lettuce 
A valuable commercial crop when grown under 
proper conditions. Thousands of cars of Lettuce 
are shipped annually from the mountain states 
and California. A commercial acreage of Lettuce 
requires good, rich soil, no check in growth, care¬ 
ful weeding and thinning and cool weather during 
the heading season. These requirements must all 
be met to have a real success and to make big 
money from Lettuce. Soil can, of course, be fer¬ 
tilized to make it rich, but it is better to use a 
field which has been in alfalfa or some such soil¬ 
building crop, or the rich natural soils of the 
high mountain valleys. The growth must never 
be checked or the plants will quickly shoot to 
seed and the crop lost. Under irrigation the 
growth can bp generally controlled by watering. 
Careful weeding and thinning give the plants the 
full advantage of the fertility of the soil and also 
plenty of room for the heads to form and develop. 
Cool weather is necessary at heading time; some 
varieties will stand hot weather, but the large 
heading varieties used by commercial shippers 
will not head in hot weather. In lower altitudes 
these varieties are only used as Spring and Fall 
crops and not used to head in the Summer. 
MOUNTAIN GROWN LETTUCE SEED 
Because of the importance of the Lettuce in¬ 
dustry we are growing our Lettuce seed on our 
Mile High Farms. Here the crops are cared for 
through the season by our trained men, only per¬ 
fect plants are allowed to go to seed, so that the 
crops from this seed will be as near perfect as 
our care can make them. This mountain growing 
of the seed also tends to make the varieties early 
in maturity and gives the seed strong vitality.

Lettuce. 
Culture. One oz. to 100 feet of drill; 2 to 4 lbs. 
per acre. Mountain Iceberg and New York or Won¬ 
derful require only y 2 to 1 lb. per acre. Lettuce is 
quite hardy and may be sown before danger of frost 
is over. The seed should be sown thinly in rows 18 
to 30 inches apart. When the plants have developed 
four leaves they should be thinned to 6 inches apart 
on the smaller varieties and 14 inches apart on New 
York or Wonderful and Mountain Iceberg. The qual¬ 
ity of the crop depends to a large degree upon the 
moisture conditions and the plants should never be 
allowed to become checked in growth for want of 
water. Any such checking is apt to cause many 
plants to go to seed or produce unmarketable heads. 
Head Lettuce requires frequent, shallow cultivation 
and plenty of attention, so that one man should not 
attempt to handle more than 3 to 5 acres. 
544 Special Strain New York. (80 days.) Our strain 
of this popular variety was grown on our Mile 
High Seed Farms at 5,000 feet elevation. We have 
never seen any finer, harder heads of Lettuce than 
those in our seed fields which we selected 
for seed last Summer. The field was thor¬ 
oughly rogued so that you can bank on this 
seed being absolutely true to type. Pkt, 5c; 
oz, 20c; 44 lb, 60c; lb, $1.65, postpaid. Not 
prepaid, 5 lbs, $7.00; 10 lbs, $13.00. 
537 Special Strain New York (2-year-old seed). 
Pkt, 10c; y 2 oz, 20c; oz, 30c; 44 lb, 85c; lb, 
$2.40, postpaid. Not prepaid, 5 lbs, $10.00; 
10 lbs, $19.25. 
543 Extra Early 5084 New York. (70 days.) A brand new 
strain of New York Lettuce selected for extreme earliness. 
It produces well rounded, tight, solid heads about two weeks 
earlier than any other known strain, and the top of the head 
has a well grown leaf which protects greatly from sunscald. 
Pkt, 10c; 14 oz, 15c; oz, 25c; 14 lb, 65c; lb, $2.00, postpaid. 
Not prepaicl, 5 lbs, $7.25; 10 lbs, $14.00. 
541 Mountain Iceberg. (80 days.) Very similar to New York 
,or Wonderful. Our mountain grown strain of Mountain Ice¬ 
berg is unexcelled for high altitude Lettuce growing. A 
hardy, rapid grower, deep rooted and drought resistant. Will 
stand in cutting condition for several weeks. Pro¬ 
duces closely folded, solid heads of immense size, 
often weighing 2 or 3 lbs. The inner portion is 
beautifully blanched to a creamy white. The 
heart is solid, sweet, tender and crisp. 
Pkt, 5c; oz, 20c; 44 lb, 60c; lb, $1.65, post¬ 
paid. Not prepaid, 5 lbs, $7.00; 10 lbs, 
$13.00. 
542 Mountain Iceberg (2-year-old seed). 
‘ Pkt, 10c; 44 oz, 20c; oz, 30c; 44 lb, 85c; 
lb, $2.40, postpaid. Not prepaid, 5 lbs, 
$10.50; 10 lbs, $20.00. 
539 Improved Hanson. (80 days.) The 
most reliable variety for general plant¬ 
ing; stands hot weather better than any 
other type. Sure heading even in mid¬ 
summer. Good sized heads. Large, crum¬ 
pled leaves. Pkt, 5c; oz, 15c; 44 lb, 35c; 
lb, $1.00, postpaid. Not prepaid, 5 lbs, $4.00. 
538 Iceberg. (80 days.) Crisp and brittle, too 
brittle for shipping, but excellent for home gar¬ 
dens. Curly leaves and fine flavor. Will stand 
considerable hot weather. Quite distinct from 
the variety known to the produce markets as 
“Iceberg.” That variety is “New York.” Pkt, 
5c; oz, 15c; 44 lb, 45c; lb, $1.35, postpaid. Not 
prepaid, 5 lbs, $6.00.
