 wasp's. Mr. Reaumur thought that this was 

 the stuff out of which the wasp made paper, and 

 it has since been found out that he was right. 

 The animal wets its little bundle of bruised 

 wooden fibres or threads with a kind of glue 

 that it has, and this makes it stick together 

 like pulp or paste; and while it is soft, the 

 wasp walks backwards, and spreads it out 

 with her feet and her tongue, until she has 

 made it almost as thin as the thinnest paper. 

 With this she lines the top of the hole in 

 which she is going to build her nest, for she 

 always begins at the top. But this is so thin
