near Baltimore, have a capital of 100,000 
doilars, and make 450,000 pounds of a 
guality, said lately to be equal to any 
imported. There are several other 
powder-mills in Pennsylvania, and other 
places; but the total amount of gun- 
powder made in the United States is not 
ascertained, 
Larthen and Glass Ware.—A_ sufii- 
cient quantity of the coarser species of 
pottery is made every where; and infor- 
mation has been received of four manu- 
factures of a finer kind lately established. 
One at Philadelphiay with a capital of 
11,000 dollars, manufactures a species 
sinilar to that made in Staffordshire in 
Envgland; and the others, in Chester 
county in Pennsylvania, in New Jersey, 
and on the Ohio, make various kinds of 
queen’s-ware. 
Information has been obtained of ten

the extension of the domestic manufac- 
ture, which suvplies precise!y one-half of 
the consumption, being prevented by the 
want of workmen. 
Some of those manufactures make also 
green bottles, and other wares: and two 
works, employing together six glass- 
blowers, have been ‘lately erected at 
Pittsburgh, and make decanters, tum- 
blers, and- every other description of 
flint glass, of a superior quality. 
Chemical Preparations.—Copperas is | 
extracted in large quantities from pyrites 
inVermout, Ne dersey; and Tennessee, 
About 200,000 pounds of oil of vitriol, 
and other acids, are annually manufac- 
tured in a single establishment at Phila- 
delphia. Various other preparations 
and drugs are also made there, and in 
some other places; and the annual 
aimount exported, exceeds 20,600 dollars 
in value. 
Salt. —The salt-springs of Onondago 
and Cayuga in the state of New York, 
furnish about 300,000 bushels a-year ; 
and the quantity may be increased in 
proportion to the demand. Those of the 
western states and territories supply 
ahout an equal quantity; that known by 
the name of the —— Saline, which

belongs to the United States, making 
now 130,009 bushels. Valuable disco- 
veries have also lately been made on the 
banks of the Kenhawa. But the annual 
impurtation of foreign salt’ amounts to 
more than three milhons of bushels, and 
cannot be superseded by American salt,. 
unless it be made along the sea-coast. 
~The works in the state of Massachusetts 
are declining, and cannot proceed unless 
the duty on foreign salt should again be 
laid. Itis necessary to shelter the works 
- from the heavy summer rains by light 
roofs moving on rollers. This conside~ 
rably increases the expense; and it ap- 
pears that the erection of ten thousand 
superficial square feet, costs one thous 
sand dollars, and that they produce only 
two hundred bushels a-year. A more 
favourable result is anticipated on the 
coast of North Carolina, on account of 
the difference in the climate; and works, 
covering 275,000 square feet, have been 
lately erected there. 
Miscellaneous.— Respecting the other 
manufactures enumerated in the former 
part of this report, no important or cor- 
rect information has been received, ex- . 
cept as relates to the two following: 
Straw bonnets and hats are made with 
great success; and a small district in 
Rhode Island and. Massachusetts an- 
nually exports to other parts of the 
Union, to the amount of 250,000 dollars, 
Several. attempts have been made to 
print calicoes, but it does not seem that 
the manufactures can, without additional. 
duties, stand the competition of similar 
foreign articles. The difficulties under 
which they labour are stated in the p-e- 
tition of the calico-printers of Phiiadel- 
phia to Congress. A considerable ca- 
pital has been vested im an establishment 
near Baltimore, which cai print 12,000 
yards a-week, and might be considerably, 
extended, if the profits and the demand, 
afforded cai amte nie encouragement, 
From this sketch of American manu- 
factures, it may with certainty be inferred. 
that their annual product exceeds one 
hundred and wwenty millions of dollars. 
And it is not improbable that the raw, 
materials used, and the provisions and. 
other articles consumed, by the manu-, 
facturers, create a home wikia for agri- 
cultural products not very inferior to that 
which arises from foreign demand. A 
result more favourable than might have. 
been expected from a view of the natue 
ral causes which impede the introdaction, 
and retard the progress, of manulactureg
