stiff and firm,
toothed and blistered; the seeds are white.

The Brown Cos blanches white and tender, and is exceedingly crisp and
well flavored; but the dark-brownish color of the exterior leaves is
deemed an objection, and it is often displaced by really inferior
varieties. In weight and measurement, it differs little from the Green
Paris Cos. Extensively cultivated and much esteemed in England.

GRAY PARIS COS. _Vil._

Head of the form of an inverted cone; green, with a grayish tone about
the top; compact, and forming well without tying. The exterior leaves
are numerous, deep-green, erect, firm, and prominently blistered. The
full diameter of the plant is nearly twelve inches, and its weight about
twenty ounces; the seeds are white.

The Gray Paris Cos is brittle, and of tender texture; but is considered
inferior to the other Paris Cos sorts, and is but little cultivated.

GREEN PARIS COS. _Vil._

Kensington Cos. Sutton's Superb Green Cos. Wellington. Ady's Fine Large.

Head inversely conical, compact; leaves deep-green, erect, firm, hooded
or cowl-formed towards the ends, and serrated on the margin; the ribs
and nerves are large and prominent. When fully grown, the entire
diameter of the plant is fifteen or sixteen inches, and its weight
twenty-four ounces; the seeds are white.

It is considered one of the best of the Cos lettuces; and, though not so
hardy as the Brown Cos, is a good variety for forcing, and furnishes a
tender, well-flavored head during summer. Whether for spring, summer, or
autumn, it is an excellent sort. It attains a large size, is of a fine
green color, and, "from the manner in which the outer leaves cove over
the interior ones, blanches well without having to be tied together."

It has a tender, brittle leaf; is some days earlier than the White
Paris; and is the principal variety employed by the market-gardeners of
Paris for cultivating under glass.

GREEN WINTER COS. _Vil._

Head elongated, somewhat of the form of the preceding variety;
deep-green, and not forming well, unless the exterior leaves are tied
together at the tips; the outer leaves are large, erect, concave,
toothed on the margin, and prominently blistered; the seeds are black.

It blanches well; but the ribs and nerves of the leaves are
comparatively coarse and hard. Well adapted to winter culture; but, as a
summer lettuce, of little value.

MONSTROUS BROWN COS. _Vil._

Two-headed.

Head of remarkable s
