They then tried an evaporated decoction of malt. By making 
a wort, or simple decoction of malt (the malt should be put in 
cold w ater, and gradually heated, for boiling water sets it, as the 
term is, T. C.) and evaporating this to the consistence of common 
molasses, they produced a species of mobsses sufficiently similar 
to the common article, and sweet enough to be used witii coffeej, 
at an expence of materials that would amount to about thirty-five 
cents per galloni This experiment deserves to be repeated in 
every family. 
I do not give Mr. Cloud’s method of making Seltzer water, or 
his method of procuring Zinc from the common brown and black 
blende, because I hope he will give these processes himself. 
Gunfiowder.-—! observe in the papers the following advert 
Usement, I know nothing of the improvements suggested, but 
from the advertisement itself ; and I have no knowledge whatever 
of the advertiser. I copy it, as notice of the application of steam 
to the manufacture of gunpowder, which I believe to be practica- 
ble, and also to be a real improvement. Whether it be adopted in 
Eiigland or not, or whether among the numerous patents granted 
for the application of steam to the arts and manufactures of that 
country, any patent has been taken out for its application to gun- 
powder, I know not. I wish somebody would publish a list of 
patents taken out in that country and in this, from the date of the 
first vol. of the Repertory of Arts, in 1794, to the present timU. I 
have not the command of more than 20 volumes. I have no doub^ 
but very many of our home-bred patents would be found in the 
English collection. I will take an opportunity, ere long, of giving 
my opinion on patent rights. But I have at present no intention of 
applying this remark to the subsequent advertisement, for I know 
hot the process. Steam has long been applied in England to the 
warming of buildings, to medicinal baths, to the heating of boiler^ 
4o dying, to bleaching, to soapffioiling, to distilling, to the heating of 
drying-houses, as malt-floors, &g. &C. and also to the drying of gun- 
powder. Mr. Woolf in the description of his boiler, which I shall 
give in my next, expressly notices the application of steam to the 
gunpowder manufacture ; and it is ^ated as being generally in- 
troduced, in the article gunpowder, Rees’s Encyclopedia. Howe- 
ver, as it is certainly a very feasible, and very important improve^- 
inent, I give place to the following advertisement.
