HEADING VARIETIES 
A packet will sow 25 feet of row; an ounce 150 feet. 
CULTURE. Sow in seed bed as early in spring as the ground can be worked and at intervals 
thereafter. When plants have made 2 or 3 leaves, transplant into rows, 15 inches apart and 1 foot 
apart in the row. For early forcing, sow in hot-bed from commencement to middle of winter. Let- 
tuce requires very rich, moist soil, and will do better when transplanted. For general crop, sow 
out doors as early in the spring as ground can be worked, in drills 18 inches apart and thin to 10 
inches apart in the rows. 
Big Boston, 
76 days. Especially valuable for summer and fall use outdoors and for forcing. 
In the eastern states is largely grown on muck ground for shipping to the 
large cities. Leaves comparatively smooth, glossy and crisp; color light green, 
sometimes tinged brown on the edges. Forms a well folded head, buttery 
yellow at the heart and of excellent quality. 
WHITE BOSTON —Special Strain 
We have given this name to our new White Boston selection to distinguish 
its superior quality and type from the regular White Boston popular several 
years back. Plant and head entirely light green, smooth leaves and straight 
edges. Heart buttery and yellow. This strain the best in existence. About 75 
days to maturity. 
HEADING VARIETIES ‘‘SICEBERG TYPES’’ 
CAUTION—All Iceberg types of lettuce are affected by conditions. Minor 
variations in temperature, nutrition, and moisture at critical periods may cause a 
particular strain to head well or poorly. Consequently, it is difficult to produce a 
strain well adapted to a wide range of conditions. The varieties we offer have been 
tried under the variable weather of Eastern States. It seems too great a risk to 
make large plantings of any one variety at one time. Successful growers make 
successive plantings.
