5.  Pig  Meal. 
Anything  almost,  as  has  often  been  remarked,  will  “ pass  ” 
as  pig  meal. 
The  following  is  an  instance  of  a waste  material  of  little 
value  so  used  : —

This  was  really  oat  offal,  and  cost  21.  15s.  per  ton  in 
London,  a price  much  in  excess  of  its  real  value. 
B.  Fertilisers. 
The  generally  satisfactory  nature  of  the  supply  of  these 
has  been  commented  on.  The  ordinary  manufactured  fertilisers, 
such  as  superphosphate,  dissolved  bones,  &c.,  have  almost 
always  come  up  to  guarantee.  So,  too,  has  basic  slag,  though 
the  reason  for  this,  in  the  giving  of  a safeguarding  guarantee, 
has  been  referred  to.  Peruvian  guano  continues  to  be  an 
article  that  can  be  obtained,  and  several  very  high-class  lots 
have  been  met  with. 
1.  Basic  Slag. 
High  quality  samples  of  this  were  the  following  — •

“A”  was  a purchase  of  35  tons,  bought  at  Liverpool  at 
21.  11s.  6d.  per  ton,  with  a guarantee  of  12  per  cent,  of  phos- 
phates. It  will  be  seen  that  the  quality  turned  out  8^  per  cent, 
above  the  guarantee. 
“B”  was  a purchase  of  33  tons,  purchased  at  21.  6s.  per  ton, 
delivered  at  Newark,  Notts.,  under  a guarantee  of  38-45  per  cent, 
of  phosphates.  It  came  out  no  less  than  16  per  cent,  above  the 
minimum  guarantee. 
2.  Peruvian  Guano. 
Although  it  was  supposed  at  one  time  that  the  stores  of 
Peruvian  guano  were  worked  out  and  that  no  more  would  be
