would  amount  to  41.  7s. ; phosphate  of  lime,  2010  per  cent.,  or 
450  lbs.  in  a ton,  which,  at  three  farthings  per  lb.,  would  amount 
to  1 1.  8s.  2d.  On  this  calculation  the  total  value  of  a ton  of  the 
manure  would  be —

We  are  by  no  means  sufficiently  advanced  in  our  knowledge 
of  the  action  of  manures  to  determine  their  relative  value  with 
great  nicety ; and  however  useful  in  a general  way  a money  test, 
such  as  that  we  have  employed  above,  may  be,  as  a safeguard 
against  serious  errors,  we  must  be  content  at  present  to  allow  a 
considerable  latitude  for  its  application  in  special  instances.  It 
will  be  enough  to  say  that,  in  reference  to  other  manures,  espe- 
cially Peruvian  guano,  the  price  of  this  “animal  manure”  has 
not  been  chosen  far  from  the  mark."*  It  is  greatly  to  the  ulti- 
mate interest  of  the  farmer  that  all  attempts  to  make  such  sources 
of  manure  available  should  be  encouraged;  and  it  is  to  be  hoped 
that  we  shall  more  frequently  hear  of  importations  of  this  kind. 
Mr.  Hudson,  acting  upon  my  advice,  has  passed  five  tons 
of  this  manure  through  a riddle.  The  finer  part,  consisting  of 
dry  flesh  with  the  smaller  particles  of  bones,  he  has  sown  for 
wheat,  whilst  the  larger  fragments  of  bones  retained  by  the 
screen  will  be  dissolved  in  acid  and  kept  for  the  root-crops  of 
next  year. 
Box-Manure. — The  following  is  the  analysis  of  a sample  of 
manure  from  the  cattle-boxes  of  Mr.  Charles  Lawrence,  of  Ciren- 
cester. It  need  hardly  be  mentioned  that  such  an  analysis  only 
applies  with  correctness  to  the  sample  actually  analysed,  since 
the  composition  of  manure  from  cattle,  produced,  as  it  is,  from 
different  kinds  of  food  in  different  proportions,  and  mixed  with 
more  or  less  of  straw,  cannot  in  any  two  cases  be  the  same.  A 
careful  analysis  is,  however,  at  all  times  worth  recording. 
The  sample  is  from  a mixture  of  the  manure  of  bullocks, 
horses,  and  pigs.  “ The  bullocks,”  says  Mr.  Lawrence,  “were 
eating  mangold  and  mixed  hay  and  straw  chaff,  moistened  with 
4 lbs.  of  linseed-cake  dissolved  in  boiling  water,  and  3 lbs.  of 
barley-meal  per  head  per  diem.  The  horses  similar  chaff,  with 
a bushel  of  beans  and  a bushel  of  oats  per  head  per  week.  The 
pigs  were  fed  with  mangold  and  pollard. 
The  first  column  of  the  succeeding  table  gives  the  analysis  of 
the  ash  of  the  manure;  the  second  that  of  the  manure  in  its 
natural  state. 
* Before  1 had  learned  at  what  price  the  manure  was  ottered  for  sale,  I had  advised 
Mr.  Hudson,  on  the  grounds  of  its  chemical  composition,  not  to  bring  it  to  a much 
higher  price  than  5 1.  a ton.
