OBSERVATIONS  UPON  THE  SORGHUM  SACCHARATUM.  109 
finishing  this,  the  two  preceding  had  formed  a  thick  opaque  mass 
of  good  crystals. 
Filled  one  mould,  weight  20  flbs. — weight  of  mould  4f-  lbs. 
net  weight,  15i  Sbs.  Filled  one  mould,  weight  14|  lbs. — weight 
of  mould  4j  fibs.,  net  weight  10  lbs.  Total  weight  25£  ft>s. ;  and 
next  morning  set  them  on  pots  to  drain ;  also  boiled  down  the 
juice  from  the  tops,  4|  gallons,  which  produced  with  the  scums 
13|  33bs.  of  molasses. 
Nov.  2d.  Knocked  out  the  proceeds  of  this  experiment  with 
the  following  results,  viz. 
1st  mould  yielded  sugar     7  lbs,      molasses      8|  lbs, 
2nd    "        "  sugar     4£  lbs.    molasses      5-1  lbs„ 
Tops  "  molasses     13^  lbs. 
Total  product  of  arow  200  ft.  long,  sugar  11-50 lbs.,  molasses  27-25  lbs, 
Fifty  rows  of  cane,  four  feet  apart, 
and  218  feet  long  constitutes  an 
acre.    Hence  200  ft.  is  18  ft.  less 
than  l-50th  of  an  acre;  therefore 
add  pro  rata  1-03  "  2-45 
Products  of  l-50th  of  an  acre       sugar     12-53  lbs.,  molasses  29-70  lbs. 
Which  multiplied  by  50 
makes  the  product  of  an  acre       sugar  625.50  lbs.  molasses  1485-00  lbs. 
A  gallon  of  molasses  weighs  12  lbs.  ;  therefore,  1485  Bbs. 
equals  123|  gallons ;  for  the  acre,  625  lbs.  sugar,  and  123 J 
gallons  molasses,  produced  from  18,148  canes,  yielding  1,737 
gallons  of  juice,  weighing  9  lbs.  per  gallon,  or  15,633  lbs.,  being 
4  per  cent,  of  sugar,  and  9  per  cent,  of  molasses,  or  13-50  per 
cent,  together. 
This  sugar  is  of  a  yellowish  brown  color,  about  as  dry  as,  and 
about  the  color  of,  2nd  quality  Cuba  sugar,  such  as  is  used  by 
refiners. 
[Thus  far  we  have  given  all  the  details,  and  mostly  in  the 
language  of  the  author  of  these  experiments.  In  what  follows 
we  propose  as  nearly  as  possible  to  give  the  general  results  in 
as  brief  a  manner  as  possible. — Ed.] 
3rd  Experiment,  Oct.  23d,  temp.  36°  to  55°  F.  Encouraged 
by  the  favorable  progress,  the  author  decided  on  a  more  extended 
trial ;  and  as  the  weather  threatened,  he  had  500  feet  of  cane 
cut  and  stored  in  the  barn.    Nearly  a  month  having  elapsed
