VELLUM CORD. 211 



COVERED CORDAGE. 



This is made of different kinds of thread, twine, rope, or 

 annealed wire, according to the use for which it is intended. 

 These are first coated with Hquid compound cement, and then 

 wound or rolled with a covering of vellum or tissue, tissue 

 being used for the lighter, and vellum for the heavier kinds. 



It has been suggested by nautical men, although it has not yet 

 been proved by trial, that it would answer well for standing rig- 

 ging, and other purposes on ship board. It is also designed for 

 canal drag-ropes, seine twine, clothes-lines, and, briefly, for all 

 uses where ropes are much exposed to wet, and where the first 

 cost is not a'consideration, which will, for this article, be greater 

 than for common rope. 



This description of cordage is used for some articles described 

 hereafter, where great strength is required, instead of the cord 

 composed entirely of vellum. 



VELLDM CORD. 



There are two methods of manufacturing this article : one is 

 that of cutting either by hand or machinery, and rolling up strips 

 of gum-elastic tissue or vellum into cord of any size desired. 

 The other is that of pressing the vegetable leather of a suitable 

 thickness, by grooved call^nders, into cord of the size required. 

 It has not sufficient strength to be used for many purposes by 

 itself, without combining with metal wire, or flax, hemp or cot- 

 ton twine. Its chief use is for the covering of glass and earthen 

 ware, for the manufacture of cord ware, and other articles here- 

 after described among the numerous applications.
