humbbrearnd  “BITTER  OIL’’  INSECTICIDE.  V  BRAND. 
For  Destroying  Caterpillars  of  Winter  Moth;  Apple  Blossom  Weevil;  Woolly  Aphis,  or  American  Blight;  Bed  Spider 
on  Gooseberry  bushes;  Caterpillars  on  Gooseberry  bushes  [ see  Special  Testimonial  from  Messrs.  E.  P.  DIXON  <£■  SONS  on  this  matter]  ■, 
for  Washing  Hop  Bines,  for  preventing  and  destroying  Fly;  and  as  a  Wash  for  Bose  Trees,  Chrysanthemums,  &c. 
‘BITTER  OIL”  has  been  found  a  most  valuable  dressing  for  Fruit  and  Forest-Tree  Nurseries;  also  for  thoroughly  cleansing  the  inside  of 
Vineries,  and  as  a  Winter  Dressing  for  Outside  Walls  on  which  Fruit  Trees  are  trained. 
BITTER  OIL”  mixes  readily  with  cold  water  rain-water  is  to  be  preferred  -forming  a  soft,  milky  fluid;  there  is  no  separation  of  oily  or  soapy 
matter,  and  the  wash  so  produced  will  not  scald  young  and  tender  foliage,  or  growing  shoots. 
“  BITTER  OIL  ”  is  a  certain  and  rapid  exterminator  of  all  Insect  Pests  at  the  minimum  of  cost  to  the  user,  and  without  the  least 
danger  to  the  tenderest  of  plants,  or  injury  to  the  most  delicate  foliage.  It  is  practically  inodorous,  and  does  not  leave  the  slightest  stain  on  plants 
after  spraying  or  dipping  in  the  strongest  solution,  when  the  directions  for  use  for  different  requirements  are  adhered  to.  “  BITTER  OIL  ” 
is  not  only  a  safe  “  killer,”  but  the  proprietors  claim  for  it  the  property  of  rendering  (as  its  title  implies)  those  forms  of  plant  life  subject  to 
insect  and  parasitic  pests  dressed  with  this  preparation,  absolutely  intolerable  to  them,  and  consequently  immured  from  their  ravages. 
TESTIMONIALS  selected  from  many  received,  and  entirely  unsolicited: — 
From  Mr.  J.  Allsop,  Head  Gardener  to  the  Right  Hon.  Lord  Hotham,  Dalton 
Holme,  Yorks. — “  I  am  pleaded  to  say  that  I  find  it  most  effectual  in  destroying  Aphii, 
Thrip,  Green  Fly,  &c.  It  mixes  well  with  water,  and  is  very  convenient  to  use.” 
From  Mr.  j.  H.  Reynolds,  Head  Gardener  to  the  Right  Hon.  the  Earl  of 
Yarborough,  Broc-klesby  Park.  Lincolnshire.— “  After  giving  *he  ‘Bitter  Oil’  a  fail- 
trial  I  have  much  pleasure  in  testifying  to  its  thorough  cleansing  powers  ;  more  especially 
was  this  noticeable  on  a  fine  lit  of  wall  Plum-trees,  which  were  becoming  badly  infested 
with  Green-Fly  and  other  troublesome  insect  pests.  Alter  two  applications  of  ‘Bitter 
Oil  ’  the  trees  and  fruit  were  left  in  a  clean  and  healthy  state,  and  arc  now  furnishing  a 
most  satisfactory  crop.” 
A  further  letter  from  Mr.  Reynolds  reads—*'  Plums  are  showing  well  foi 
fruit,  ‘  Bitter  Oil  ’  keeps  them  beautifully  clean,  and  is  so  simple  to  use,  I  swear  by 
it  for  all  these  sorts  of  pests,  and  mean  to  apply  it  this  time  before  they  get  at 
all  bad.” 
From  Messrs.  E.  P.  Dixon  &  Sons,  the  Yorkshire  Seed  Establishment,  Hull ;  and 
Gardens  and  Nurseries,  Burton  Constable,  E.  Yorks. — ‘‘A  few  days  since  we  sprayed 
several  thousands  of  young  Gooseberry  trees  [we  are  authorised  to  state  that  some 
15,000  bushes  were  dressed]  which  were  heavily  attacked  with  caterpillars,  with  the 
most  gratifying  results.  Myriads  of  these  destructive  pests  were  instantly  destroyed,  and 
after  the  third  day  not  a  single  one  could  be  found  alive,  and  though  the  operation  was 
performed  under  a  burning  sun,  not  the  least  damage  was  done  to  either  fruit  or  foliage. 
We  have  used  ‘  Bitter  Oil  ’  largely  the  past  two  years  in  our  Fruit  and  Plant- Houses  and 
Nurseries,  and  have  found  it  thoroughly  effectual  iD  destroying  Scale,  Thrip,  Red-spider, 
and  Mealy-bug,  without  the  slightest  injury  to  the  most  tender  foliage.” 
Well  shake  the  Oil  before  measuring  off  quantity  required.

This  Preparation,  used  according  to  printed  instructions,  will  effectively  eradicate  all  Insect  Pests  to  which  Plants  are  liable,  and  ivithout  in  any  way 
injuring  the  foliage,  or  leaving  any  unpleasant  smell.  From  the  peculiarly  cleansing  nature  of  this  preparation,  Plants — particularly  in  towns — have  their

Opinion  of  a  PRACTICAL  GARDENER  on 
From  Mr.  George  Picker,  Head  Gardener  to  Francis  J.  Pease,  Esq,  J.P., 
Haslewood,  Yorks. — “  I  duly  tested  the  ‘Humber  Brand’  Plant  Cleanser.  I  have 
been  waiting  to  see  results  before  I  replied  respecting  Mildew  on  Rose  bitshes  ...  I 
mixed  1  to  8  and  syringed  on  to  Stove  Plants  for  Mealy  Bug,  which  we  are  greatly  troubled 
with.  Results,  instant  death  to  Bug,  without  the  least  injury  to  roots  or  foliage— all 
the  “HUMBER  BRAND"  Plant  Cleanser, 
that  Plant  Growers  can  wish  for  ;  then  I  syringed  Rose  bushes  for  Mildew,  where  foliage 
was  covered  with  the  spores  .  .  .  waited  to  see  if  the  spores  covered  the  foliage  again,  up 
to  the  present  they  are  quite  free  from  the  pest ;  also  the  Stove  Plants  remain  free  of  the 
Bug.  .  .  .  The  death  of  insects  is  assured  without  injury  to  tender  foliage  ...  I  believe 
that  it  |H.  B.  Plant  Cleanser]  will  do  all  that  any  reasonable  person  may  desire.” 
Further  opinion  of  a  Practical  Gardener. 
Mr.  Picker  writes  further— “  The  safety  that  it  can  be  applied  over  tender  foliage,  Red  Spider,  White  Fly,  &c.  ;  and  1  par£  insecticide  to  8  parts  of  water  will  kill  Mehly  Bug. 
and  the  certain  death  of  all  insect  pests,  places  the  Humber  Brand  Insecticide  in  the  The  foliage  should  be  thoroughly  wetted  either  by  dipping,  or  syringing  under  and  over 
front  rank  of  all  insect  eradicators.  It  is  a  capital  insecticide  for  cleansing  trees  (Fruit  the  foliage.  The  insecticide  will  take  4 parts  more  of  water  when  th9  water  is  heated  to 
trees)  of  the  American  Blight  ft  to  8  of  water]  .  .  .  For  winter  dressing  Vines,  Peaches,  145deg.  Fahrenheit,  or  even  to  ISOdeg.,  and  at  this  temperature  will  not  hurt  leafless 
and  Fig  trees  it  will  be  invaluable.  I  find  1  part  of  insecticide  to  12  parts  of  water  to  trees.  If  all  cultivated  Plants  and  Trees  could  be  syringed  over  once  a  fortnight  with 
iradic.ite  Mildew  and  Green-Fly  ;  1  part  insecticide  to  10  parts  of  water  to  kill  Thrips,  Humber  Brand,  they  would  always  be  clean  and  pleasant  to  look  upon.”
