crown. The entire diameter of a well-grown plant is
about twelve inches, and the weight from ten to twelve ounces. The seeds
are white.

It is one of the best sorts for summer cultivation, as it not only forms
its head readily in warm and dry weather, but remains long in head
before running to flower. For forcing, or for sowing early in the
season, some other varieties would succeed better. Though sometimes
slightly bitter, it is crisp, tender in texture, appears to be adapted
to our climate, and is recommended for cultivation.

TENNIS-BALL.

Green Ball. Button. Capuchin. Hardy Hammersmith. _Vil._

One of the oldest and most esteemed of the Cabbage lettuces. The head is
below medium size, dark-green, remarkably solid if grown in cool
weather, but often loose and open-hearted if cultivated during the
summer months; the surplus leaves are few in number, deep-green,
slightly curled, and broadly, but not prominently, blistered; the seeds
of the genuine variety are black.

The Tennis-ball Lettuce is remarkable for its extreme hardiness.
Winter-grown plants, or those raised in cool, moist weather, will
measure about ten inches in diameter, and weigh eight ounces; whilst
those raised under opposite conditions rarely exceed seven or eight
inches in diameter, or weigh more than four or five ounces.

It is slow in running to seed, and the head blanches white and tender.
"It requires little room in frames in winter, and yields a great return
in spring, as almost the whole plant is eatable." A large Cabbage
Lettuce, tinted with brown about the head, is erroneously known in some
localities as the "Tennis-ball."

TURKEY CABBAGE.

Similar to the Imperial Head; the principal if not the only difference
consisting in the color of the seeds, which are black.

VERSAILLES. _Vil._

Swedish. Blond Versailles. Sugar-lettuce.

Head pale yellowish-green, large, long, and compactly formed; the
exterior leaves are large, numerous, wrinkled, and coarsely blistered.
When in its greatest perfection, the extreme diameter of the whole plant
is about fourteen inches, and its weight twelve or fourteen ounces. The
seeds are white.

This variety forms its head quickly and uniformly; cabbages white and
crisp; is slow in shooting up to seed; flourishes in almost every
description of soil, and at all seasons, except, perhaps, in extreme
cold; and, though sometimes slightly bitter to the taste, is crisp,
tender, and of good quality.
