, erroneously known in New England as the "White Portugal,"
is unquestionably the true Silver-skin, as described both by English and
French authors. The application of the term "Silver-skin" to the common
Yellow Onion, as very extensively practised by seedsmen and market-men
in the Eastern States, is neither pertinent nor authorized.

STRASBURG. _M'Int._

Yellow Strasburg. Flanders. Dutch. Essex.

This is the variety most generally cultivated in Great Britain. Its form
varies from flat to globular, or oval; bulb large, three inches wide,
and full two inches in depth; outside coating brown, of firm texture.
Divested of this, the color is reddish-brown, tinged with green. Flavor
comparatively mild. It is a very hardy sort, succeeds in cold
localities, and keeps well.

The Strasburg and Deptford Onions much resemble the common Yellow Onion
of New England; and the difference between the sorts is not great, when
English-grown bulbs of the first-named varieties are compared with the
bulbs of the Yellow Onion, American-grown: but seeds of the Strasburg or
Deptford, raised in England and sown in this country, almost invariably
fail to produce plants that form bulbs so generally or so perfectly as
American-grown seeds of the Yellow Onion.

TOP OR TREE ONION.

Egyptian.

Bulb large, a little flattened; producing, instead of seeds, a number of
small bulbs, or onions, about the size of a filbert, which serve as a
substitute for seeds in propagation. The flesh is coarse; and the bulbs
are very liable to decay during winter, unless kept in a cool and dry
situation. The variety has been considered rather curious than useful.

_Planting and Culture._--"Either the bulbs formed in the ground, or the
small ones upon the stems, may be planted out in April or May. The
former are set one foot apart in each direction, and the stem-bulbs four
inches apart in rows eight inches asunder. Stems that bear heavily
require to be supported. When ripe, the stem-bulbs should be dried, and
kept free from damp in a cool place."

TRIPOLI. _Thomp._

Flat Madeira. De Madere Plat. _Vil._

This is one of the largest varieties. The bulb tapers abruptly from the
middle to the neck, and almost equally so to the base. It is five inches
and upwards in diameter; color light reddish-brown,--beneath the skin,
pale brownish-red, tinged with green.

It requires the whole season, and in some localities is considered
excellent for a late crop. The fle
