kind, is its native adhesive properties and plastic nature, before 

 being subjected to the process of vulcanizing. It is so very 

 plastic, that the labor and expense of working it into almost any 

 article, or form, becomes barely nominal, for which reason, when 

 substituted for many other things, such as shoes, heavy harness, or 

 leather trunks, where the leather has to be stitched to form the 

 article, this material has a very great advantage on the score of 

 economy. The facility with which it is thrown into any form, 

 or moulded in any shape, is not surpassed by wax, or by lead, 

 or any other of the soft metals. The parts of any article made 

 of it, and of all the fabrics before being vulcanized, adhere upon 

 the slightest touch, and upon slight pressure with hand tools, or 

 the fingers even, the parts become one mass, so that the seams, 

 without a stitch, become the strongest part of the article, for the 

 reason that they are the thickest. The labor of manufacturing 

 some ptain articles, is often less than the pasting of paper would 

 be. The reader may form an idea of the readiness with 

 which it yields to the will of the operative, from the fact that 

 one girl will make up twenty, and even more, pairs of shoes, or 

 five coats, in one day.

 with types, without requiring to be dampened like paper,

10th. FACILITY 



OF BEING ORNAMENTED BY PAINTING, BRONZING, GILDING, JAPANNDfC, AND 

 MIXING WITH COLORS. 



It is printed in oil or block printing, with much greater facility 

 than oilcloths, because it is softer, and it retains oil-painting
