In rich loams, where the solution of the minerals of the soil is
rapid, and where 10 to 20 per cent, of vegetable matter is
incorporated in the earth, tobacco may be obtained for many years, but
it is always an exhausting crop. It has been stated that 170 Lbs. of
mineral matter are removed in less than three months from one acre of
land, by a crop of tobacco. This is very much more than wheat or other
grains abstract from the soil in eight or nine months.

Tobacco is now very extensively cultivated in France and other
European countries, in the Levant, the East and West Indies; and a
little is grown at the Cape and in the Australian Settlements.

A good deal of tobacco is raised in Mexico, but only for home
consumption, as its export is prohibited. It forms an article of
culture in Brazil and some of the South American republics, and is
grown to a small extent along the Western shores of Africa. It is from
North America, however, that we derive the bulk of our supplies of
this great article of commerce, which, with cotton, forms the chief
agricultural wealth of the United States.

In 1821, the tobacco exported from the Brazils amounted to 29,192,000
Lbs., but its cultivation was greatly injured by the siege of the
capital in 1822-23. Fresh seed was subsequently obtained from Cuba,
and in 1835 the exports were 6,051,040 Lbs.

131 cases of Princeza snuff were shipped from Bahia to Lisbon, in
1835; about 60,000 Lbs. per annum of this snuff being now manufactured
at Bahia, with the aid of two steam-engines. The exports of tobacco
from Bahia increased from 2,048,000 Lbs. in 1833, to 6,051,040 Lbs. in
1835. The average shipments are about 21,000 bales and rolls.

The army of smokers in Great Britain and Ireland consume yearly about
six millions of pounds worth of tobacco. The duty alone paid upon
snuff and tobacco for the people of Great Britain, averages
four-and-a-half millions sterling a year! The quantity
consumed--smoked, snuffed, or chewed--during the same period, is about
28 millions of pounds weight, or about four pounds weight per an
