while  the  packer  assorted  and  graded  all  the  fruit  received,  and  so 
was  able  to  establish  uniform  brands.  The  price  for  the  raisins  in 
the  sweat-box  has  varied  considerably.  It  has  been  as  low  as  four 
cents  a  pound,  but  with  the  increase  in  production  and  the  widen- 
ing of  the  market  there  has  been  a  steady  stiffening  in  prices,  and 
last  year  from  five  to  six  cents  was  paid. 
The  greatest  raisin  county  in  the  State  is  Fresno,  where  the  soil 
is  peculiarly  adapted  to  grape  culture.  That  county  last  year  pro- 
duced about  625,000  boxes  of  raisins  of  the  best  quality.  River- 
side came  next,  with  225,000  boxes.  Twenty  years  ago  there  were 
less  than  1,500  grape  vines  in  all  San  Diego  County.  Now  there 
are  3,000,000.  Yolo  was  the  scene  of  some  of  the  earliest  raisin 
making,  and  its  output  last  year  was  130,000  boxes.  The  most 
carefully  prepared  statistics  show  the  entire  raisin  product  of  the 
State  to  have  been  in  various  years  as  follows:  1875,  222,000 
pounds;  1 880,  1,500,000  pounds;  1885,  9,500,000  pounds;  and  in 
1889,  32,678,000  pounds.  What  the  yield  of  the  present  year  will 
be  cannot  be  estimated  as  yet  with  any  accuracy,  but  it  will  prob- 
ably reach  45,000,000  pounds,  for  the  increase  in  acreage  is  very 
great.  Last  year  there  were  less  than  60,000  acres  of  vines  in 
bearing,  but  planting  was  carried  on  extensively.  Perhaps  10,000 
acres  of  new  vineyards  are  in  bearing  this  year,  and  next  year 
nearly  95,000  acres  will  be  in  full  bearing.  This  should  swell  the 
output  of  raisins  in  1 891  to  at  least  55,000,000  pounds. 
LIQUID  KINO.1

Angophora  intermedia  (D.C.),  the  narrow-leaved  apple  tree,  is  a 
tallish  tree,  which  extends  from  Victoria  to  Queensland,  and  is  the 
only  species  of  the  genus  which  is  found  in  the  southern  colony. 
In  the  following  respect  it  is  perhaps  unique  amongst  Australian 
trees.  Frequently,  when  an  incision  is  made  into  the  bark,  and 
more  particularly  when  the  knobby  excrescences  sometimes  found 
on  this  tree  are  cut,  there  exudes  a  watery  liquid,  which  occasion- 
ally is  almost  as  clear  and  as  colorless  as  water,  and  at  other  times
