thoroughly melted. The melted mass should he poured into a canvass bag, made 
in the form of a jelly bag, with a draw-tape or string at the top, and then be sus¬ 
pended over a tub or pan of cold water. The strings of the bag being tightly 
drawn, the expression may be effected in various ways. Some press the bag 
between two strong round sticks, tied or strapped together at their ends, so as to 
resemble a pair of nut-crackers, with which two persons may by repeatedly strip¬ 
ping down the sides of the bag, express the whole of the wax. Others express it 
by making an inclined plane of a boaid, about four feet long, placing one end of 
it in the tub or pan of water, and tbe other against the breast of the assistant, who 
puts the bag on the board, and passes a round stick firmly down it, as long as thet 
wax will run. A screw press, made hot, would of course answer the purpose bel¬ 
ter than either of the above modes. 
“The crumbled combs might be put over the fire in a steam kettle, with water 
under it, and the wax which runs through might afterwards be melted again, and 
passed through the bag. The new combs will melt almost entirely, but the old 
ones, owing to their cells having received so many linings, will preserve their 
form, the wax running from them, but in small quantities. 
“The vessel used for melting wax should be capable of containing a good deal 
more than is put into it, as the contents may boil up suddenly, and occasion loss 
and inconvenience, as welt as danger. The wax having been separated from the 
water in which it was melted, should be re-melted with just water enough to pre¬ 
vent burning; and having been well skimmed, may be poured out into proper 
moulds for forming cakes, the vessels being first rinsed with cold water to prevent 
the wax from adhering to them. The melted wax should be placed near the fire, 
and covered over, to cool gradually, or the cakes will be liable to crack. If it 
be desirable to have the wax in a very pure state, it may be boiled over and over 
aarain with fresh water.”
