The  Theory  of  Rain-making 
Not  long  ago  the  Hope  Farm  man  dis¬ 
cussed  the  possibilitievS  of  rain-making, 
and  stated  his  belief  that  some  day  this 
matter  would  be  at  least  partly  solved  by 
the  plan  of  using  a  very  fine  dust  blown 
out  into  clouds  and  fogs.  The  theory 
upon  which  this  opinion  was  based  is 
found  in  a  recent  book  bv  Prof.  W.  L. 
Moore,  who  states  that  the  ordinary  rain¬ 
drop  is  an  accumulation  of  particles  of 
water  gathered  around  a  speck  of  dust. 
Some  recent  experiments  in  blowing  dust 
into  fogs  seem  to  give  considerable  hope 
that  the  plan  might  finally  'be  developed. 
The  Department  of  Agriculture  now 
issues  a  statement  from  the  United  States 
Weather  Bureau  to  the  effect  that  this 
plan  is  not  feasible.  The  Weather  Bu¬ 
reau  says  that  the  presence  or  absence 
of  dust  particles  in  the  atmosphere  does 
not  have  anything  to  do  with  the  distribu¬ 
tion  of  rainfall.  Over  the  ocean,  where 
there  is  the  least  dust,  it  says,  enormous 
quantities  of  rain  fall,  and  that  the  most 
dust  in  the  atmosphere  occurs  over  dry 
and  semi-arid  regions.  It  has  been  sug¬ 
gested  that  powdered  quicklime  might  be 
employed  in  this  way  to  precipitate 
moisture.  The  Weather  Bureau  says 
that  the  effect  of  the  lime  would  be  to 
dry  the  air.  Unless  exceedingly  fine,  this 
lime  dust  blown  into  the  air  would  ab¬ 
sorb  about  one-third  of  its  weight  of 
moisture,  and  then  fall  to  the  earth, 
leaving  the  air  drier  than  before.  It 
says  that  finely-powdered  marble  would 
be  best  for  carrying  out  this  experiment 
in  rain-making,  because  the  marble  would 
not  rob  the  atmosphere  of  any  of  the 
moisture  present.  On  the  whole,  the 
Weather  Bureau  states  that  these 
schemes  for  developing  rainfall  are  en¬ 
tirely  futile. 
In  spite  of  all  this  wise  pronouncement 
we  still  think  that  something  will  be  de¬ 
veloped  out  of  this  plan.  We  have  lived 
long  enough  to  know  that  most  of  these 
wise  men  disparage  practically  every  new 
idea  in  practical  scientific  advancement 
that  is  not  originated  by  someone  offi¬ 
cially  connected  with  them,  and  we  have 
seen  too  many  of  these  supposed  impos¬ 
sible  things  develop  into  practical  com¬ 
pletion  to  discourage  us  in  the  thought 
that  some  day  rain-making  will  be  pos¬ 
sible. 
Saving  the  Lawn 
An  owner  of  a  rural  home  and  an  auto¬ 
mobile  makes  use  of  the  device  shown  in 
the  picture  to  keep  his  wheels  on  the 
concrete.  Scores  of  drivers  seem  to  be 
unable  always  to  hit  the  Headways,  or 
to  keep  them  on  when  they  do  strike  them. 
Many  auto  owners  make  use  of  two  strips 
of  concrete  for  a  driveway  to  the  shelter-

house  in  the  rear,  leaving  grass  in  the 
center.  This  man  caused  a  gutter  to  be 
molded  in  the  right-hand  treadway.  It 
is  about  4  in.  deep  and  wide  enough  to  al¬ 
low  the  two  right  wheels  of  his  car  to 
roll  without  friction.  In  this  way  his 
wheels  guide  him  into  his  shelter  without 
running  off  one  side  or  the  other,  thus 
preventing  the  cutting  up  of  an  otherwise 
well-kept  side  yard.  j.  L.  GRAFF.

Be  comfortable 
and  save  money 
You  pay  just  as  much  — 
and  sometimes  even  a  trifle 
more — for  an  Exide  Battery 
as  for  an  ordinary  battery. 
But  by  the  time  you  need  to 
replace  an  Exide  you  have 
had  such  long  service  and  so 
few  repairs  that  it  has  proved 
about  the  most  economical 
thing  you  ever  purchased  for  your  car. 
batteries 
As  for  comfort,  an  Exide  does  what  you 
want  it  to  do,  and  it  does  it  when  you 
want  it  done.  You  don’t  worry  about  how 
long  it  is  going  to  take  you  to  get  your 
engine  running  or  whether  there  is  going 
to  be  plenty  of  light  when  you  turn  the 
switch. 
A  battery  to  be  friends  with 
Give  an  Exide  ordinary  care  and  it  will 
give  you  extraordinary  service.  Its  sturdi¬ 
ness  and  its  willing  power  make  possible 
that  solid  comfort  you  have  a  right  to  ex¬ 
pect  from  your  car. 
You  can  check  these  statements  by 
asking  Exide  owners,  and  there  are  mil¬ 
lions  of  them.  Or  you  can  prove  it  to  your¬ 
self  by  driving  to  the  nearest  Exide
