During the last twelve months a good deal of fish-guano, or 
dried fish, has been sent to England from America. Fish-guano, 
if dry and powdery, is an excellent concentrated fertiliser, ap- 
, preaching Peruvian guano in character. 
, The following analyses illustrate the variation in the compo- 
sition of dried fish, or fish-guano : —

Dried fish, it will be seen by the preceding analyses, is a 
valuable fertiliser, and a very different material from much of 
the stuff which in England is sold to farmers under the name of 
fish-manure, at a low price varying from 21. 2s. to 4/. 4s. a ton.
