46 GOODYEAR ON G U M- E L AS T I C. 



FLOOR CLOTHS. 



Are made of the plated or fibrous fabrics, either of cotton or 

 wool, and printed with oil like other floor cloths, or with callen- 

 ders and in lithography, like other India rubber fabrics. 



When printed with oil, the pattern does not wear off so soon 

 as from the common floor cloths, because the ground of the 

 carpet is softer, and when printed in lithography is still moi'e 

 durable, because the ink penetrates the gum. It is also softer 

 to the feet, does not crack under any circumstances, and 

 possesses this very great advantage, that, when the pattern is 

 worn off", the goods are hardly less valuable than when new. 

 They can be re-stamped or re-printed, and may be applied to 

 other purposes, such as tarpaulins, &c. When the gum is applied 

 to one side only of the woolen fibre, the other side being printed, 

 a woolen winter carpet, as well as a gum-elastic summer carpet, 

 is obtained from the same article. The same result is obtained 

 where one side of the goods is napped with flocks. 



MOSAIC CARPETING. 



This is made like the carpeting already described of the same 

 materials, with this difference ; the pattern is worked in or laid 

 on, the colors being mixed with elastic compound cement, and 

 laid on during the process of manufacture, while the goods are 

 in a soft state, by which means the figure becomes part and par- 

 cel of the carpet, and like mosaic, durable as the carpet itself. 

 Marbled and simple patterns are formed in this way by sten- 

 ciling. More elaborate patterns are formed by printing in 

 colors by lithography ; and when these goods are finished by the 

 method described under the head of Indelible Fabrics, (of which 

 mosaic carpeting is considered one of the most important,) as
