■only  one  is  to  be  allowed  to  carry  fruit,  the  duplicate  only  re¬ 
maining  until  choice  can  be  made  of  the  best,  and  in  case  of  two 
shoots  being  left,  one  ought  to  be  near  the  stem,  so  as  to  keep 
the  spur  as  short  as  possible.  Weakly  Vines,  however,  may  be 
given  more  latitude,  so  as  to  secure  stouter  wood,  larger  and 
plumper  eyes,  and  better  bunches  in  future. — St.  Albans.

PRIMULA  LEAVES  CURLED  AND  SPOTTED  (F.  H.  P.).— 
The  older  and  large  leaves  are  quite  healthy,  indeed,  very  fine, 
but  the  younger  ones  are  what  is  known  as  rusted,  curled, 
crippled,  and  spotted,  the  brown  spots  and  the  damage  generally 
being  caused  by  a  mite,  not  unlike  a  thrips  in  form,  but  smaller, 
and  not  by  any  means  easy  to  find.  It  is  very  injurious  by  its 
piercing  of  the  tissues  to  abstract  their  juices,  its  action  being 
very  pernicious,  giving  a  stunted  and  rusted  appearance  to  the 
leaves,  prejudicing,  and  often  preventing,  the  flowering.  It  is 
the  same  pest  that  causes  rust  in  Gloxinias,  Gesneras,  and 
Begonias  j  also  other  plants  grown  under  glass,  especially  those 
with  hairy  and  somewhat  thick  leaves.  It  is  a  species  of 
Tarsonymus,  and  because  found  in  Gloxinias,  Begonias,  Pelar¬ 
goniums,  &c.,  has  been  given  the  specific  name  of  the  plants. 
It  is  not  different  from  the  species  that  affects  Box  in  hot 
and  dry  places,  namely,  T.  buxi.  The  best  treatment  is  syringing 
with  tobacco  water  at  intem^als  of  about  four  days,  which  either 
kills  the  pests  or  drives  them  away.  We  have  found  this  better 
than  fumigation  with  tobacco  paper  .or  vaporisation  ivith  nicotine 
compound  at  short  intervals,  though  this  procedure  has  a  very 
decidedly  deterrent  effect  on  the  destructive  creature.  Perhaps 
a  little  fertiliser  would  have  a  good  effect  on  the  plants,  such 
as  a  mixture  of  three  parts  superphosphate,  two  parts  powdered 
saltpetre,  and  one  part  sulphate  of  lime,  mixed,  using  about  a 
thimbleful  to  each  pot,  mixing  ivith  a  little  soil,  and  keeping 
from  the  necks  of  the  plants. 
SPOTS  ON  CHRYS.4NTHEMUM  LEAVES  (Mummer).— The 
leaves  are  infested  with  the  Chrysanthemum  rust  in  the 
uredospore  condition,  and  then  known  as  Uredo  tanaceti,  and  in 
the  telentospore  stage  as  Puccinia  tanaceti,  though  some 
fungologists  consider  the  uredo  as  belonging  to  Puccinia  hieraci, 
probably  from  the  telentospore  stage  not  being  obseiwed  by  these 
observers  in  the  Chrysanthemum,  which  was  generally  noticed  in 
this  country  and  in  France  in  1897,  There  is  no  question  of  its 
being  quite  new  to  the  Chrysanthemum,  and  of  its  being  first 
noticed  on  the  variety  Niveum  in  the  United  States,  and  in  all 
probability  was  introduced  from  America  into  Europe.  It  was 
very  prevalent  in  1898,  especially  in  the  uredo  or  summer  fruit 
condition,  in  which  it  forms  minute,  snuff-coloured  clusters  of 
spores  on  the  under  surface  of  the  leaves,  and  in  badly  affected 
cases  the  pustules  are  often  so  numerous  as  to  cover  the  greater 
surfacial  part  of  the  leaves.  This  stage,  unless  checked,  is 
rapidly  reproduced,  and  extends  itself  throughout  the  summer 
months,  indeed,  throughout  the  year,  owing  to  the  Chrys¬ 
anthemum  plants  being  kept  under  glass  during  the  winter 
months.  When  the  leaves  are  fading  the  telentospore  form  of 
fruit  is  produced,  which  differs  from  the  uredo  form  in  the 
pustules  being  darker  in  colour  and  not  powdery.  The  disease 
may  be  kept  in  check  by  spraying  at  intervals  with  potassium 
sulphide  .solution,  dissolving  loz  of  the  sulphide  in  a  quart  of 
hot  Avater,  then  make  up  to  gallons  with  cold  rain  water.  As 
the  pustules  are  situated  on  the  under  side  of  the  leaves,  the 
spraying  must  be  upivards  so  as  to  wet  them,  or  in  the  case  of 
small  plants,  they  may  be  dipped  in  the  solution.  The  removal  of 
affected  leaves  as  soon  as  the  first  appearance  of  the  pustules  is 
noticed,  and  before  the  cuticle  of  the  leaf  is  broken,  and  buim- 
ing  them,  is,  however,  the  sure.st  mode  of  riddance.  Some 
growers  destroy  all  affected  plants,  and  commence  anew  with 
perfectly  clean  ciittings  or  plants.  This  is  often  impracticable, 
therefore  repressive  measures  must  be  promptly  taken,  and  with 
close  observation  and  persevering  treatment  the  disease  may  be 
overcome.  Veltha  Emulsion,  advertised  occasionally  in  our 
columns,  has  been  used  effectively  for  preventing  or  destroying 
Chrysanthemum  rust,  and  is  also  good  against  other  fungous  and 
insect  pests  to  which  Chrysanthemums  are  liable.

Trade  Notes. 
To  the  nurseryman  who  hugs  the  outskirts  of  large  citie* 
(and  for  obvious  I'easons  most  firms  are  under  this  necessity), 
the  builder  and  the  prospector  for  a  suitable  site  for  a  suburban 
residence  are  a  continual  dread.  From  the  latter  cause  the 
firm  of  Mr.  John  DoAvnie,  Beechhill,  Murrayfield,  N.B.,  were 
about  a  year  ago  relieved  of  the  ground  which  they  had  leased 
adjoining  their  Beechhill  Nursery.  Simultaneously  with  this 
loss,  however,  they  had  contracted  for  a  long  lease  of  Belgrave 
Park,  situated  on  the  high  grounds  of  Corstorphine  Hill,  over¬ 
looking  the  village,  and  immediately  above  the  new  station, 
from  which  it  is  about  ten  minutes’  Avalk.  This  ground,  which 
is  laid  out  in  the  usual  cojuvenient  nursery  system,  is,  from  its 
situation,  exposure,  and  soil,  admirably  suited  for  the  produc¬ 
tion  of  hardy  well  rooted  stock.  This  comprises  fruit  rtees 
and  bushes  in  great  Amriety,  including  the  neAver  ones,  such  as 
Comet,  Red  Currant,  Victoria,  and  Boskoop  Giant  Black 
Currant;  May  Duke,  Langley  Gage,  and  Beauty  Gooseberries; 
Apples,  Allin^on  Pippin,  BoAvhill  Pippin,  James  Grieve,  Charles 
Ross.  Roses  also  appear  to  be  about  to  receive  careful  and  exten- 
srte  cultiA'ation ;  a  fine  lot  of  several  thousands  which  were 
budded  last  autumn  appear  to  be  in  good  condition,  and  from 
the  healthy  and  vigorous  look  of  the  stocks  should  make  splendid 
plants  by  autumn.  A  general  nursery  stock  of  trees  and  shrubs, 
large  and  small,  too  numerous  in  variety  to  mention  by  name, 
occupies  the  remainder  of  the  ground.  An  office  and  packing 
shed  is  built  in  a  convenient  part,  and  behind  these  are  several 
ranges  of  frames  filled  with  cuttings  of  Conifers,  shrubs,  &c.  As 
already  mentioned,  the  nursery  is  within  easy  access  of  Corstor¬ 
phine  Station,  on  the  new  suburban  raihray,  which  is  to  be 
opened  by  the  beginning  of  February.  It  is  also  to  be  con¬ 
nected  by  telephone  Avith  Beechliill,  Avhieh  is  at  present  in 
communication  with  the  offices  at  144,  Princes  Street.  This 
extension  of  telephone  should  have  been  completed  some  time 
ago,  but  the  increased  demand  made  upon  the  Telephone  Com¬ 
pany  through  the  laying  of  underground  Avires  has  made  it  im¬ 
possible  for  them  to  overtake  their  usual  extension  work.—

cation  of  Native  Guano  in  field  and  garden.  The  booklet  for  1902 
is  to  hand.  Reports  are  included  from  every  part  of  England,

berries,  Vines,  Chrysanthemums,  lawns,  Roses,  and  Cucumbers. 
Writing  from  Rocester,  Mr.  T.  Titley  (fourth  order)  says:  “Used 
for  Roses,  Pansies.  Gladioli,  Sweet  Peas,  &c. ;  vegetables:  Pota¬ 
toes,  Kidney  Beans.  Celery,  &c.  ;  fruit :  Apples,  Gooseberries, 
Raspberries,  Strawberries.  Splendid  results  in  every  instance. 
Vei'y  large  crops  Potatoes,  Beans,  &c.,  flowers  splendid.  I  have 
used  no  other  kind,  and  am  more  than  satisfied  with  your  Native 
Guano.  I  sold  some  to  my  neighbours,  and  they  all  speak  very 
highly  of  it  and  intend  using  it  again.”
