This  material  cost  35s.  per  ton,  but  was  very  moist  and  in 
lumpy  condition  ; so  that,  considering  the  difficulty  of  applying 
it,  it  would  have  to  be  regarded  as  decidedly  dear  at  35s.  per 
ton,  the  price  at  which  it  was  offered.

The  above  is  the  analysis  of  a manure  made  from  the  con- 
demned carcasses  of  meat  found  on  the  London  markets. 
This,  it  will  be  noticed,  was  of  a distinctly  rich  nature,  and  its 
condition,  moreover,  was  very  satisfactory.
