of  that  State.    It  is  as  follows,  viz  : — -

The  pamphlet  of  Mr.  Lovering  concludes  with  the  following 
synopsis  which  we  copy  without  abridgement,  viz  : — 
1st.  That  it  is  obvious  that  there  is  a  culminating  point  in  the 
development  of  the  sugar  in  the  cane,  which  is  the  best  time  for 
sugar  making.  This  point  or  season  I  consider  to  be  when  most 
if  not  all  the  seeds  are  ripe,  and  after  several  frosts,  say  when 
the  temperature  falls  to  24°  or  30Q  F. 
2d.  That  frost,  or  even  hard  freezing,  does  not  injure  the  juice 
nor  the  sugar,  but  that  warm  Indian  summer  weather  after  the 
frost  and  hard  freezing,  does  injure  them  very  materially,  and 
reduces  both  quantity  and  quality. 
3d.  That  if  the  cane  be  cut  and  housed,  or  shocked  in  the  field 
when  it  is  in  its  most  favorable  condition,  it  will  probably  keep 
unchanged  for  a  long  time. 
4th.  That  when  the  juice  is  obtained,  the  process  should  pro- 
ceed continously  and  without  delay. 
5th.  That  the  clarification  should  be  as  perfect  as  possible  by 
[*This  amount  is  probably  too  great ;  see  experiment  4th  .—Ed.]
