to  “The  Editor,”  12,  .  Mitre  Court  Chambers,  Fleet  Street, 
London,  E.C.  It  is  requested  that  no  one  will  write  privately 
to  any  of  our  correspondents,  seeking  information  on  matters 
discussed  in  this  Journal,  as  doing  so  subjects  them  to  unjustifiable 
trouble  and  expense.

DISEASED  LEAVES  OF  TUBEROFS  -  ROOTED 
BEGONIAS  (Surrey). — The  leaves  are  infested  with  rust  mite 
(Tarsonyinus  begoni),  which  is  one  of  the  most  pernicious  pests, 
as  it  is  very  injurious  by  its  biting  of  the  tissues  and  mode  of  life 
of  the  young  in  their  early  stages,  causing  the  leaves  to  have  a 
rusted  appearance,  completely  checking  the  growth  and  often 
causing  the  falling  of  the  leaves.  The  best  preventive  and  repres¬ 
sive  treatment  is  to  spray  the  plants,  on  the  under  side  of  the 
leaves  particularly,  as  well  as  on  the  upper  surface,  with  tobacco 
water,  loz  of  the  strongest  shag  tobacco  being  placed  in  a  vessel 
and  a  quart  of  boiling  water  poured  in  it,  then  covering  over 
closely  allow  to  stand  until  cool,  then  strain  and  apply  by  means 
of  a  spray  diffuser,  the  simple  article  used  by  hairdressers,  and 
costing  about  2s.  6d.,  being  very  suitable  for  the  purpose,  repeat¬ 
ing  at  intervals  of  a  few  days. 
DECAY  IN  WOOD  OF  PEACH  TREES  (Gardener).— The 
pieces  of  wood  cut  from  Peach  trees  are  affected  by  gummosis,  or 
gumming,  a  disease  assigned  to  various  causes,  some  authorities 
referring  to  the  fungus  named  Coryneum  Beyerickii,  and  others 
to  Cladosporium  epiphyllum,  and  others,  again,  to  Gloeosporium 
fructigenum.  In  .your  case  it  appears  to  arise  from  attack  of  the 
very  common  Cladosporium  epiphyllum,  a  minute  fungus.  The 
disease  is  indicated  by  the  appearance  of  tearlike  drops  of  almost 
colourless  gum  oozing  from  the  branches,  and  the  part  above  and 
adjacent  becomes  brown  and  dead.  Diseased  branches  should  be 
removed  to  sound  wood  immediately  below  the  dead  or  affected 
part,  and  the  ground  given  a  dressing  of  air-slaked  lime,  applying 
as  much  as  to  make  the  soil  quite  white  all  over,  even  a  quarter  of 
an  inch  thick.  In  the  autumn  the  trees  should  be  lifted  carefully 
and  replanted,  and  some  lime  rubbish  added  to  the  soil,  say  a 
sixth,  making  the  soil  very  firm  under,  about  and  over  the  roots. 
The  gummosis  is  aggravated  by  the  excessive  vigour  of  the  trees, 
and  you  would  do  well  to  take  out  a  trench  now  one-third  the 
distance  from  the  stem  the  branches  cover  of  trellis,  and  cut  off 
all  roots  there,  the  opening  being  made  down  to  the  drainage. 
This  trench  may  remain  open  a  fortnight  or  three  weeks,  and 
then  be  filled  in,  deferring  lifting  until  the  leaves  commence 
falling. 
INSECT  TO  NAME  (Idem). — The  insect  is  the  Potato  bug 
(Lygus  solani),  which  is  found  on  various  plants,  commonly  on 
the  Potato,  and  does  some  injury,  though  not  usually  material, 
by  sucking  the  juices.  It  is,  however,  rather  uncommon,  though 
sometimes  appearing  in  great  numbers  in  late  summer,  especially 
in  the  South  of  England,  and  often,  associated  with  the  Hop  bug 
(Lygus  humuli),  is  found  on  Chrysanthemums. 
GROS  C'OLMAN  GRAPES  BACKWARD  IN  RIPENING 
(Ripener). — You  cannot  do  better  than  admit  a  little  air  con¬ 
stantly,  and  maintain  a  gentle  warmth  in  the  hot-water  pipes 
so  as  to  promote  a  circulation  of  the  air  in  the  house  and  cause 
the  moisture  to  be  condensed  on  the  glass  instead  of  on  the 
berries,  increasing  the- ventilation  early,  especially  on  fine  morn¬ 
ings.  W©  do  not  advise  forcing  treatment,  as  this  hinders  rather 
than  forwards  the  colouring  process,  and  lack  of  this  is  the 
greatest  defect,  therefore  we  should  give  the  Vines  plenty  of 
time,  not  keeping  a  higher  temperature  at  night  than  65deg,  and 
if  it  fall  to  GOdeg  in  the  morning  all  the  better,  but  from  the 
early  part  of  the  morning  gradually  raise  the  temperature  of  the 
house  to  70deg,  and  keep  between  that  and  7odeg  from  fire  heat 
through  the  day  and  until  late  in  the  afternoon  or  early  evening, 
then  allow  to  gradually  cool  down.  A  temperature  of  80deg, 
8odeg,  or  90deg  may  be  allowed  through  the  day  from  sun  heat, 
and  a  free  circulation  of  air.  Beyond  these  temperatures  we  do 
not  consider  it  safe,  for  though  the  Grapes  may  be  ripened,  they 
will  be  almost  worthless  from  appearing  unripe  through  lack  of 
colour.  The  top-dressings  of  Peruvian  guano  and  sulphate  of 
ammonia  will  not  help  the  Grapes  in  colouring,  but  a  mixture  of 
three  parts  dissolved  bones,  dry  and  crumbling,  and  two  parts 
double  sulphate  of  potash  and  magnesia,  known  in  the  trade  as 
refined  kainit,  mixed,  and  4oz  of  the  mixture  applied  per  square 
yard,  scratched  or  very  lightly  pointed  in,  is  likely  to  help  the 
Vines  in  the  current,  or  certainly  in  the  future  crop.
