The quantity of fulminating powder must be proportioned to the 
effect intended.—Idem. 
6. Cheap mode by which farmers and others may manufacture 
charcoal.—Provide a hollow cylindrical cast-iron back log for the 
fire place, not so long but that it may become heated throughout its 
length. One end may be permanently closed and the other covered 
with a cap. - Drill small holes in it from one end to the other, about 
a line in diameter. Frill this back log with blocks of wood or chips, 
and put onthe cap. When heated, the inflammable air and tar that 
issue from the holes will aid the fire. In defect of a cast iron log, a 
joint of stove pipe may answer temporarily.—Idem. 
7. Al tried recipe for burns.—Keep on hand a saturated solution 
of alum (four ounces in a quart of hot water) dip a cotton cloth in 
this solution and lay it immediately on the burn. As soon as it shall 
have become hot or dry, replace it by an other, and thus continue 
the compress as often as it dries, which it will, at first, do very rapid- 
ly. The pain immediately ceases and in twenty four hours under 
this treatment the wound will be healed, especially if the solution be 
applied before the blisters are formed. ‘The astringent and drying 
quality of the alum completely prevents them. 
The deepest burns, those caused by boiling water, drops of melted 
metal, phosphorus, gunpowder, fulminating powder, &c. have all been 
cured by this specific.—Idem. 
8. To remove a hard coating or crust from glass and porcelain 
vessels.—It often happens that glass vessels, used as pots for flowers 
and other purposes, receive an unsightly deposit or crust, hard to be 
removed by scouring or rubbing. ‘The best method to take it off, is 
to wash it with a little dilute muriatic acid. This acts upon it and 
loosens it very speedily.—JIdem. 
9. Scotch method of preserving eggs.—Dip them, during one or 
two minutes in boiling water. The white of the egg then forms a 
kind of membrane, which envelopes the interior and defends it from 
the air. This method is preferable to the varnish proposed by Reau- 
mur. 
10. Preservation of skins.—J. Stegard, tanner at Tyman, in Hun- 
gary, completely preserves raw hides from putrefaction, and restores
