L. P. GUNSON & CO., ROCHESTER, N. Y. 27 
LETTUCE—(Continued) HEADING VARIETIES 
Big Boston, Special! Select 
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 
76 days. Similar in growth to the Big Boston but entirely light green in color 
without the brown tinge. Heads are solid, compact and of excellent quality. 
Our strain is the result of years of painstaking selecting and breeding and we 
believe is superior to any other strain on the market. 
HEADING VARIETIES ‘‘ICEBERG TYPES’ 

IMPERIAL No. 44 
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. 
CORNELL 456 
A cross of Brittle Ice with Imperial! 152. This lettuce is more resistant to 
tipburn than older strains of Iceberg, therefore better adapted for mid-summer 
conditions in this State and similar sections. Due to the Brittle Ice parent, it 
is lighter in color than other strains of Imperial. This new strain is meeting 
with favor and fills a needed space in plantings of Iceberg.
