Mountain Iceberg 415 (New) 
ICEBERG AND NEW YORK VARIETIES 
Culture: Conditions necessary to grow good head lettuce 
are rich soil, plenty of moisture, and steady growth from 
the time the seeds are planted until the heads are ready to 
use. A check in growth from lack of nourishment, mois¬ 
ture or adverse conditions, usually results in total or par¬ 
tial crop failure. For most satisfactory results plant 
New York varieties so they mature in cool weather. 
After the soil is thoroughly plowed and prepared, drill 
in rows on a compact seed bed two feet apart, planting 
seed one-half to one inch deep, and from one-half to one 
pound of seed to the acre. 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. Cultivate thoroughly but not deep. 
Ground should not become dry but care must be used in 
irrigating. When weather is cold use water very sparingly 
as crop can be stunted by too much water. If the weather 
is inclined to be a little too warm, it is possible at times 
to save the crop by an abundance of water. This crop 
requires from 75 to 97 days for maturity from seeding 
time to harvest. 
NEW VARIETIES OF LETTUCE 
We doubt if any variety of vegetables has had the per¬ 
sistent and intense breeding as has been done with the 
New York and Iceberg types of lettuce. In fact, the past 
few years the development and introduction of new va¬ 
rieties has been so fast that but few seed houses or planters 
have been able to keep up with the progress. 
We have devoted a large acreage in the mountains of 
Colorado—on our farm south of Denver; also in Arizona 
and California, to the trials and development of new va- 
FOR ARIZONA 
We found I-H Improved, also No. 152 outstanding for 
crops to mature in the fall. 
Early spring crop, March and early April, Imperial D. 
and No. 615. 
For late spring crops, No. 515, No. 12, but best of all 
No. 415. 
FOR IMPERIAL VALLEY, CALIFORNIA 
We recommend Imperial D, No. 13, and Imperial 615. 
FOR SALINAS VALLEY, CALIFORNIA 
We recommend No. 152, 415. 
rieties and strains, often as many as twenty different 
varieties grow side by side in one field. We do this work 
not only for ourselves but for other large dealers in Seed 
as well as the Department of Agriculture. 
Each year new varieties with outstanding merit have 
been introduced. The latest introduction of merit has been 
Imperial 847 and No. 415. We are very much enthused 
with No. 415. In our estimation and trials it is better than 
No. 12 and No. 515. 
FOR COLORADO 
Vicinity of Denver, for early summer, June and July, 
No. 415. (See description.) 
We like next best the New Imperial 847. (See descrip¬ 
tion.) 
No. 12 was best for transplanting and early June crop, 
but we also recommend No. 415 for transplanting. 
For fall crop vicinity of Denver, use I-H Improved. 
In the mountains of Colorado, No. 415 did best, also 
No. 847, but I-H Improved for late crop. Arizona Special 
and “F” were very good. 
TWO VARIETIES BRED TO HEAD AND WITHSTAND WARM WEATHER 
Imperial 847. The past year this variety was brought out 
by Dr. Jagger of the Department of Agriculture. It was 
bred so as to head during warm weather. Our trials, 
as well as the trials of growers in Arizona and Cali¬ 
fornia, proved this to be a lettuce of exceptional merit. 
It withstands the heat and is a very consistent header. 
Our supply of seed is limited. Pkt., 10c; oz., 25c; Vi lb., 
85c; y 2 lb., $1.50; lb., $2.25; 5 lbs., $10.00, postpaid. 
Mountain Iceberg 415. This new introduction was especi-. 
ally developed with the idea to produce a variety that 
would head with the least or no tip-burn or slime. Our 
trials, both at Denver and in the mountains, proved 
this a splendid variety, we grew an excellent crop of 
clean, good sized heads, which we harvested July 12th. 
Withstands heat even better than such varieties as 
New York No. 12 and New York No. 515, which varieties 
are especially noted for withstanding hot weather. Pkt., 
10c; oz., 20c; Vi lb., 80c; y 2 lb., $1.50; lb., $2.50; 5 lbs., 
$11.00, postpaid.
