Fish  Guano. — Under  the  name  of  marine  guano,  dried  and 
pulverised  fish-refuse  has  been  imported  from  abroad  of  late  in 
considerable  quantities. 
Dried  fish  or  marine  guano  has  given  much  satisfaction  to 
farmers  who  applied  it  to  cabbages,  mangolds,  autumn-sown 
wheat,  and  all  crops  for  which  Peruvian  guano  is  used  with 
advantage  as  a manure. 
Marine  guano  varies  considerably,  as  will  be  seen  by  the  sub- 
joined analyses,  and  should  always  be  bought  under  a guarantee 
stating  the  price  per  unit  of  ammonia  and  of  phosphate  of  lime. 
During  the  past  season  it  has  been  sold  at  about  16s.  per  unit 
per  cent,  of  ammonia,  and  Is.  Gd.  to  2s.  per  unit  per  cent,  of 
phosphate  of  lime.
