RASPBERRIES   AND   BLACKBERRIES.
These  two  fruits  are  so  near  akin  that  they  are  subject  to
the  attacks  of  the  same  diseases  and  enemies.  The  most
fatal  scourge  of  red  raspberries  that  I  have  seen  is  what  is
called  at  Marlboro'  the  curl-leaf;  and,  if  unchecked,  it  will

eventually  banish  the  famous  Hudson  River  Antwerp  from
cultivation.  As  yet,  no  remedy  has  been  found  for  it  that
I  am  aware  of.  I  believe  it  to  be  contagious,  and  would
advise  that  the  plants  be  dug  out  and  burned  immediately,
and  that  plantations  of  strong,  healthy  plants  be  made  on
new  land  that  has  never  been  in  raspberries.  I  also  sug-
gest the  free  use  of  wood-ashes  and  well-decayed  compost.
As  far  as  my  experience  goes,  this  disease  is  confined  to  for-
eign varieties,  and  almost  wholly,  as  yet,  to  the  Antwerps.
Mr.  Fuller,  in  the  paper  already  named,  describes  a  dis-
ease among  blackberries  that  resembles  the  raspberry  curl-
leaf  so  closely  that  it  may  be  identical,  and  spring  from  the
same  cause.
"  Some  ten  years  ago,  the  cultivators  of  the  blackberry  in  va-
rious parts  of  New  Jersey  noticed  that  the  ends  of  the  young,
growing  canes,  in  summer,  would  occasionally  curl,  twist  about,
and  often  assume  a  singular,  fasciated  form,  resulting  in  an  en-
tire  check  to  their  growth.  The  leaves  on  these  infested  shoots
did  not  die  and  fall  off,  but  merely  curled  up,  sometimes  assum-
ing a  deeper  green  than  the  healthy  leaves  on  the  same  stalk.
