316  Report  to  the  Annual  General  Meeting, 
from  time  to  time,  to  members,  for  their  private  information, 
accounts  of  cases  of  adulteration,  misrepresentation,  or  over- 
charge which  had  been  brought  to  the  notice  of  the  Chemical 
Committee,  has  been  received  with  much  satisfaction.  Three 
of  such  circulars  have  been  issued  during  the  year,  and  have 
aroused  great  interest,  and  been  productive  of  much  good. 
It  is  well  to  record  that  the  practice  of  adulterating  Sharps  and 
other  offals  with  sawdust  and  g3’psum — exposed  in  the  circulars 
referred  to — has  now  entirely  ceased.  At  the  same  time  other 
cases,  such  as  one  of  “ Locust  and  Oil  Cake  ” containing  6^  per 
cent,  of  sand  ; of  linseed  cake  with  per  cent,  of  sand  ; of 
the  occurrence  of  castor-oil  bean  in  feeding  materials  ; and  of 
a “ Patent  Fertiliser  ” sold  at  70s.  per  ton  but  not  worth  40s. 
per  ton,  have  been  duly  notified.  In  the  general  work  of  the 
laboratory  the  large  increase  in  sales  of  Soya  bean  and  cake 
has  to  be  specially  mentioned,  and  the  advent  of  this  new  and 
useful  feeding  material  is  to  be  welcomed.  At  the  Seventh 
International  Congress  of  Applied  Chemistry,  held  in  London 
in  May,  the  Society  was  represented  by  Mr.  Bowen- Jones, 
Chairman  of  the  Chemical  and  Woburn  Committee,  and  by  its 
Consulting  Chemist. 
21.  The  work  at  the  Woburn  Experimental  Farm  and  Pot- 
Culture  Station  has  progressed  well.  The  official  visit  of 
inspection  was  held  on  July  29,  and  on  the  day  following  a 
visit  of  members  of  the  Society  was  organised  ; this  practice, 
which  has  been  in  abeyance  for  some  years,  thus  being 
reverted  to.  In  addition,  several  other  visits,  ffuch  as  that  of 
the  Northamptonshire  Agricultural  Society,  the  Glamorgan- 
shire Agricultural  Society,  and  others  by  private  individuals, 
have  taken  place.  The  Field  Experiments  have  included  an 
extensive  series  on  the  relative  value  of  the  new  nitrogenous 
manures.  Calcium  Cyanamide  and  Nitrate  of  Lime,  in  com- 
parison with  Sulphate  of  Ammonia  and  Nitrate  of  Soda  ; also  a 
further  trial  has  been  given  to  “ Nitro-bacterine,”  and  other 
methods  for  inoculating  leguminous  and  other  crops,  and  the 
experiments  with  Magnesia  on  different  field  crops  have  been 
carried  a stage  further. 
At  the  Pot-Culture  Station  all  the  above  investigations 
have  been  duplicated,  in  addition  to  the  Hills’  Experiments 
and  other  work  of  enquiry.  The  appendix  to  the  Report  of 
the  Royal  Commission  on  Sewage  Disposal  contains  a full 
account  of  the  Experiments  conducted  at  the  Woburn  Pot- 
Culture  Station,  which  have  been  very  material  in  fixing 
the  value  to  be  attached  to  sewage  sludge.  An  exhibit  from 
the  Pot-Culture  Station  was,  as  usual,  sent  to  the  Gloucester 
Show,  Mr.  Freear,  the  resident-in-charge  at  the  Station, 
attending  throughout  the  meeting.
