Glue*

a viscous fluid, which, when dry, preserves its tenacity 
and transparency in every part, and has more solidity, 
colour, and viscidity, in proportion to the age and strength 
of the animal from which it is produced^ 
Glue is of the greatest use in many of our principal 
manufactories, particularly that of hats.

Remarks by the Editor,— Philadelphia the pro- 
cess is this. The cuttings parings, &c<. of skins, and 
other materials that will boil to a jelly, are immersed for 
2 or 3 days in lime water, to take olf the hair. They are 
then washed well. They are put in a coarse canvass bag^ 
suspended by a chain from a large iron arm fixed in the 
brickwork. The bag is immersed in the boiler of water s 
the materials are gradually dissolved. The feculences, 
add to the dung heap. The solution is evaporated till on 
trial being cold, it is gelatinous ; in this state, while hot, it 
is poured into long wooden moulds somewhat broader 
than the usual breadth of a piece of glue. It is then cut 
into lengths while in the box, by children, w^ho take out 
the solid mass of jelly, being a little longer, a little broad- 
er than the usual size of glue- cake, and thick enough 
(the depth of the wooden trough, box, or mould) to make 
half a dozen cakes of glue. It is then earned and placed 
before the man who cuts it. This is done by a square 
frame with brass wires, set at such distance apart, that each 
cutting will make a cake of glue. By one motion> 
pressing the brass wires through the jelly toward his breast 
against which a board is placed, half a dozen, (or if ne- 
cessary, more) cakes of glue, or rather of jelly, are cut 
and separted at once. These are carried away, put upon net- 
ting under a shed, and dried gradually in the air : by 
which means, the jelly is hardened into glue. 
This business, cannot be carried on, but between Sep-
