The  Trials  of  Hop-Drying  Plant,  1909. 
207 
In  connection  with  the  above  figures  I have  to  make  the 
following  observations  : — 
(1)  The  whole  of  these  samples  represent  hops  of  good 
quality  as  measured  by  the  resins.  The  soft  resins — these  being 
to  a large  extent  the  measure  of  the  preservative  value — are 
high,  and  the  hard  resins  which  are  of  little  or  no  preservative 
value  are  low. 
(2)  In  no  case  has  any  considerable  loss  occurred  between 
the  total  resins  present  in  the  green  hops  and  those  found 
in  the  dry  hops,  thus  showing  that  the  methods  of  drying 
adopted  have  been  such  that  no  undue  disintegration  of  the 
hops  with  consequent  loss  of  resins  has  occurred.  In  this 
respect  the  whole  of  the  samples  are  satisfactory. 
(3)  The  moisture  percentage  in  the  dry  hops  is  satis- 
factorily low  in  the  bulk  of  the  samples,  and  assuming  that  for 
the  purpose  of  a good  keeping  hop  it  is  not  desirable  that  the 
moisture  percentage  should  exceed  10  per  cent.,  then  it  will  be 
seen  that  five  out  of  eight  samples  conform  to  that  suggested 
standard.  In  some  of  the  samples,  however,  the  moisture  is 
decidedly  high,  this  being  the  case  most  markedly  in 
“ Partridge  D.  Fuggles,”  in  which  I consider  the  moisture 
to  be  seriously  high,  whilst  it  is  higher  than  desirable  in 
“ Shew  C/13  ” and  “ Partridge  Mathon.” 
(4)  I have  been  requested  to  allot  marks  to  the  samples 
on  the  following  points  : — 
A.  Resins. 
B.  Moisture. 
C.  Arsenic. 
And  taking  perfection  as  10,  I place  the  samples  in  the 
following  order  : — 
(A)  Resins.  Shew  8,  Partridge  8,  Whiting  7. 
These  figures  refer  not  to  the  total  resins  present,  but  to 
the  difference  in  resins  between  the  green  hops  and  the  dried 
hops  and  the  character  of  those  resins. 
(B)  Moisture.  Whiting  10,  Shew  9,  Partridge  8. 
(C)  Arsenic.  Partridge  9,  Whiting  8,  Shew  8. 
The  exact  figures  of  arsenic  are  not  given,  but  the  average 
of  each  of  these  samples  conforms  to  what  I consider  is  a 
fair  standard  of  not  containing  more  than  one-fiftieth  of  a 
grain  of  arsenic  per  lb.
