TRAVELLING BAGS. 



Numerous kinds of these are manufactured of different gum-

 suitable in general for the common kinds. They may be made 

 up with the needle, and secured by different kinds of fastenings,

apron or mouth attached to the top, which may be dropped

 handle in the middle, and a cut the whole length, into which the 

 mouth of the bag is slipped. This tube is equally well adapted 

 for traveling bags made of other materials besides gum-elastic ; 

 it will be found one of the most simple and convenient fasten- 

 ings, and may be made quite secure by a padlock at the end.

INCOMPRESSIBLE BAGS. 



The incompressible bag, which is designed to pack in the 

 smallest compass when collapsed, is made of gum-elastic plated

 by means of the valve tube described on page , and 

 their inflation prevents their contents being damaged by pres- 

 sure. They are well adapted to carry light articles, such as
