LETTUCE. 
Next to the Tomato the Lettuce is the most 
important under-glass crop, some authorities 
even placing it first. The following are the 
most approved forcing varieties in use at the 
present time. Our strains of these are most 
carefully selected. 
Emperor Forcing Lettuce. A small early 
yellow variety, compact growet, very crisp and 
tender, solid and beautifully colored; a favorite 
sort for forcing. Packet, .05; oz., .20; J 4 tt>, .50. 
LETTUCE PHILA. EY. DUTCH BUTTER. 
Hittinger’s Belmont Forcing Lettuce. A 
carefully selected strain of the Boston Market 
or white-seeded Tennis Ball, a distinct improve- 
ment and strongly recommended on account of 
its quick growth and firm heads. Packet, .5 ; 
oz., .10; 30. 
Big Boston Forcing Lettuce This variety 
succeeds better in a cool house or a cold frame 
than any other forcing sort, producing large 
heads, 12 inches across, beautifully bleached, 
and of fine quality. It has also become popular 
in the South to grow for the Northern markets.

Wheeler's Tom Thumb Forcing Lettuce. 
A small, hard-heading variety, very solid and 
crisp and an excellent under-glass sort. Centres 
finely bleached and of a rich buttery yellow. 
Packet, .5; oz., .15; -40- 
Deacon Lettuce. While this is usually 
considered a summer Lettuce, there is nothing 
better for under-glass where extra large heads 
are wanted, and we strongly recommend it for 
that purpose. The most sure heading of any 
large buttery variety. Packet, .5; oz., .15; 
y< tb, -40.

leaved sort, largely grown under glass in the

mended. Packet, .5; oz., .10; J 4 tb., - 3 °-
