IRRIGATION  PUBLICATIONS . 
Having  recently  received  inquiries  as  to  where  information 
might  be  secured  relative  to  the  irrigation  of  small  areas,  the  fol- 
lowing publications  are  recommended  as  giving  much  valuable 
data : 
“The  Use  of  Small  Wafer  Supplies  for  Irrigation.”  By  Samuel 
Fortier,  Chief  of  Irrigation  Investigations. 
This  article  discusses  the  possibilities  of  securing  water  supplies 
from  springs,  wells,  and  stored  storm  waters,  and  gives  the  results 
of  the  use  of  such  supplies  in  typical  instances.  The  methods  of 
developing  springs,  and  building  small  reservoirs  are  described, 
and  the  installation  and  operation  of  small  pumping  plants  are  dis- 
cussed. This  article  appeared  in  the  Yearbook  of  the  U.  S.  De- 
partment of  Agriculture  for  1907,  but  it  has  also  been  printed 
separately. 
“Losses  of  Irrigation  Water  and  Their  Prevention.”  By  R.  P. 
Teele. 
The  irrigation  investigations  carried  on  by  the  Office  of  Ex- 
periment Stations  for  the  last  ten  years  have  had  for  their  primary 
object  the  securing  of  the  best  use  of  the  available  water  supply. 
The  measurements  made  have  shown  large  losses  of  water  by 
seepage  from  canals,  by  evaporation  from  fields,  by  percolation 
beyond  the  reach  of  plant  ropts,  and  by  wasteful  use.  This  article 
brings  together  the  results  of  all  the  measurements  of  losses 
made,  and  describes  the  measures  used  to  prevent  them.  It  is 
largely  a compilation  from  previous  reports,  and  brings  all  this 
matter  together  in  a single  article.  It  first  appeared  in  the  An-
