other
objects, maintaining the value of all the slave property in the
country, and supplying the people with an article of general
use and prime necessity, has actually diminished the price
one-half in twelve years.

"In paper A, it will be seen that the prices in 1818 ranged
from $14 to 15, and that in 1829 they had fallen to $7.50.

"In paper marked B, it will be seen, that the brown of Havana
has fallen 3 cents in 6 years, from 10 to 7 cents, while the
sugar of Louisiana has varied from 8-1/2 to 6-1/2. The price
of sugar has in that time depreciated more than the duty, and
will produce still greater effect. The general average of
Havana brown, for six years, is 9-3/4, which now sells at from
7 to 8. The general average of Louisiana for the same period is
8-1/4; the present price ranges from 6-1/2 to 7-1/2. The sugar
of Louisiana now sells in New-Orleans at 5-1/2; freight, &c.
will bring it to 6-1/2 in the Atlantic ports."

Mr. Johnston has no doubt of the capacity of the sugar region of the
United States to supply all our demands for it, for a long period to
come.

"Without entering into any exact calculation, I can with
confidence assure you, that Louisiana alone can produce enough
for the consumption of the country for twenty-five or thirty
years, and including Mississippi, Alabama, Florida, and Georgia
south of the 32d degree, will supply it for twice that period.

"It thus appears, that the people of Louisiana, under a
confidence in the permanency of the policy of the government,
have embarked their fortunes in the production of an article of
extensive use; that they are now in the course of successful
experiment, which promises, in a few years, to supply the
consumption of the country; that they have opened a new field
of agricultural industry and enterprise, requiring a vast
amount of labour and capital; that they have actually reduced
the price of the article one-half, and have saved the country
an expense of six or seven millions a-year, and will reduce the
price still lower, when the experiment is complete."

Having found in our "History of Louisiana," the feeble commencement of
the culture of the sugar cane in that country, we thought it not beside
our purpose, and likely to be agreeable to our readers, to trace it to
its present strong and f
