collect  the  bnvk  ns  a commercial  article.  The 
common  forms  of  wattle  (A.  melaiio.tzjilon  aiul‘ 
A.  doalbata)  are  more  plentilul  on  the  Nilgiris 
than  the  .species  A.  decurroift  and  P.  pjfcnantha, 
which  yield  ricli  tanning  barks;  but  wherever  the 
better  species  have  been  planted  they  have  grown 
vigorously  and  w(;ll,  and  the  bark  is  ecpially  rich 
in  tannin  as  tliat  from  trees  growing  in  Australia. 
A sample  of  bark  from  A.  decHrre)ix  grown  on  the 
Nilgiris  was  forwarded  to  London,  and  it  was 
stated  that  the  sample  was  in  good  condition 
and  rich  in  tannin,  ilr.  Hooper  also  made 
e.xtracts  or  “Tannage”  from  tliese  wattle  bark 
preparations  which  hold  the  virtues  in  a con- 
centrated form,  and  is  much  bettor  tlian  tlie  crude 
bark  tor  e.vporting.  There  is  a good  nnirket 
in  Kurope  for  well-prepared  wattle  bark  extract, 
and  the  demand  has  been  on  the  increase  during 
the  last  few  years.  The  following  are  the  tables 
referred  to  : —

cular names  by  which  they  are  known  in  Ceylon),

♦The  common  name  of  this  is  given  as  the  “Manilla  Tamarind”  and  the  botanical  synonym  as  Iiwa  dulcis 
commonly  known  in  Ceylon  as  the  " Madras  Thorn,”  which  is  evidently  the  tree  meant  and  not ' the  sensitive  plant 
(.Jimos.i  pudica).  ' ‘ 
PREVENTION  OF  PLANT  DISEASES. 
In  all  civilized  countries  the  respective  Govern- 
ments have  thought  it  fit  to  enact  laws  to  prevent 
the  introduction  or  spread  of  animal  diseases, 
particularly  epizootics.  There  is  no  doubt  that 
these  acts  and  laws  are  based  at  least  in  their 
principle  on  laws  regulating  the  preservation  of 
the  health  of  man.  The  necessity  for  the  in- 
troduction of  laws  for  protecting  animals  from 
disease  has  been  greater  than  e.xists  in  the  case 
of  man,  since  man  is  able  to  act  for  himself,  and 
where  he  lajcoguises  danger  he  usually  takes  the 
iirst  opportunity  to  avoid  it.  In  the  case  of 
animals,  there  is  little  doubt  tliat  if  they  are 
allowed  to  have  their  own  way  their  instinct 
would  guide  them  and  (as  far  as  that  is  possible)  to 
jirotect  tliemselves  from  the  r,.viges  of  epizootsie.
