Character of 

 jood glue. 



Judgement of 

 the tikes. 



AJtT OF MAKING CLUE,. 



thought to be ftrong enough (which is known either by the 

 length of time a certain quantity of water and materials have 

 boiled, or by its appearance during ebullition), it is poured 

 into frames or moulds of about fix feet long, one broad, and 

 two deep, where it hardens gradually as the heat decreafes: 

 out of thefe troughs or receivers it is cut when cold by a fpade, 

 into fqnare pieces or cakes, and each of thefe placed within a 

 fort of wooden box, open in three divifions to the back; in this 

 the glue, as yet foft, is taken to a table by women, where 

 they divide it into three pieces * with an inflrument not unlike 

 a bow, having a brafs wire for its firing ; with this, they ftand 

 behind the box and cut by its openings, from front to back : 

 the pieces thus cut are taken out into the open air, and dryed 

 on a kind of coarfe net work, fattened in moveable (beds of 

 about four feet fquare, which are placed in rows in the glue- 

 maker's field (every one of which contains four or five rows of 

 net work) ; when perfectly dry and hard, it is fit for fale. 



That is thought the belt glue which fvvells confiderably 

 without melting, by three or four days immerfion in cold water^ 

 and recovers its former dimenfions and properties by drying. 

 GIqe that has gotfroft,, or that looks thick and black, may be 

 melted over again and refined, with a fufficient quantity added 

 of frefli to overcome any injury it may have fuftained ; but it is 

 generally put into the fettle after what is in it has been purged 

 in the fecond boiling. To know good from bad glue, it is 

 neceflary for the purchafer to hold it between his eye arid the. 

 light, and if it appears of a ftrong dark brown colour, and free 

 from cloudy or black fpots, the article is good.

With great refpecr,
