and is of excellent flavor. It succeeds well in frames; but, on account
of its large size, is not a profitable sort for forcing.

A variety, known as the "Tennis-ball" in some localities, is very
similar to this; and the "Boston Cabbage" of New England, if not
identical, seems to be but an improved form of the White Silesian.

WHITE STONE CABBAGE.

Large Golden Summer Cabbage.

Head of medium size, yellowish-green, stained with brownish-red, firm
and solid. When fully developed, the entire diameter of the plant is
about fourteen inches, and its weight sixteen ounces. The seeds are
white.

This lettuce is brittle, of tender texture and good quality, though it
is sometimes slightly bitter. It is hardy, heads readily, is slow in
running to flower, succeeds well in warm and dry weather, and is also
well adapted for frame-culture or for forcing.

YELLOW-SEEDED BROWN DUTCH. _Vil._

White Dutch. American Brown Dutch.

Head of medium size, yellowish-green, variegated with red, rounded at
the top, and tapering to a point at the base; compact; seeds yellow.

A half-early sort, of good quality, hardy, and well adapted for winter
culture, or for sowing early in spring. It somewhat resembles the
Black-seeded Brown Dutch: but, apart from the difference in the color of
the seeds, its foliage is more blistered, and more colored with red; and
the plant produces numerous sprouts, or shoots, about the base of the
head.

COS LETTUCES.

These are quite distinct from the Cabbage lettuces before described. The
heads are long, erect, largest at the top, and taper towards the
root,--the exterior leaves clasping or coving over and around the head
in the manner of a hood, or cowl. As a class, they are remarkable for
hardiness and vigor; but the midribs and nerves of the leaves are
comparatively coarse and hard, and most of the kinds will be found
inferior to the Cabbage lettuces in crispness and flavor. They are ill
adapted for cultivation in dry and hot weather; and attain their
greatest perfection only when grown in spring or autumn, or in cool and
humid seasons.

_Varieties._--

ALPHANGE OR FLORENCE COS (BLACK-SEEDED). _Vil._

In the form of the head, and in its general character, this variety
resembles the White-seeded. Both of the sorts are remarkable for size,
for hardiness and healthy habit, for the length of time they remain in
head before running to seed, and for the b
