There are two bog or water plants in our moraffes, which produce 

 much vegetable fibres attached to their feeds, one of thefc is the ty-- 

 pha, or cat's-tail ; and the other eriophorum, or cotton-rufli. The 

 fibres of the former are (hort and coarfe, but might ferve perhaps to 

 fluff cufh ions, or even coarfe beds; thofe of the latter are longer, 

 and perhaps fine enough to fpin. And as both thefe only grow on 



bogs or in water, where we at prefent cultivate no ufeful vegetables, 

 one, or both of them, might poffibly be worthy the attention of 

 thofe, who poffefs aquatic or marfhy fituations. The cultivation of 

 the cotton plant belongs to warmer climates, and may probably re- 

 quire abundant water for its vigorous growth, as well as the typha 

 and eriophorum of this country.
