THE BIYOUAC. 



The Bivouac. 



For a boat or raft, the poncho should be con- 

 structed with an oval ring, two feet wide all 

 round, which can be inflated with air. A wooden 

 or basket-work bottom (anywhere easily con- 

 structed) is then fixed underneath, by cords 

 passing through the eyelet-holes, and a commo- 

 dious raft, capable of containing two people, is at 

 once constructed, and easily worked by paddles. 

 By having the basket-work or wooden bottom 

 some inches larger than the inflated poncho, all 

 danger of the cylinder being pierced by snags of 

 rocks, or branches, is avoided. 



Mr. Cording has my pattern poncho, and fully 

 understands its manufacture.
