The  differences  in  yield  as  between  the  varieties  is  very 
significant  if  it  is  remembered  that  to  each  division  of  the 
state  the  five  varieties  believed  to  be  the  most  suitable  for  the 
district  were  sent.  When  the  averages  for  each  of  the  twelve 
divisions  are  brought  together  there  is  shown  an  average 
difference  between  the  highest  and  lowest  variety  sent  into 
each  division  of  over  four  and  a half  bushels  per  acre,  equal  to 
over  10  per  cent. 
It  should  be  also  noted  that  each  of  the  figures  in  this  table 
represents  the  average  of  the  combined  results  obtained  by 
from  six  to  thirty-one  different  farmers,  whose  names  and 
locations  are  given  in  the  report,  and  their  neighbours  are 
therefore  in  a position  to  obtain  seed  from  them  of  those 
races  which  appear  likely  to  be  most  profitable  in  the  several 
districts. 
Each  grower  also  notes  in  his  report  the  variety  which  he 
considers  best  adapted  to  his  farm,  which  is  generally  but  not 
invariably  that  which  gives  highest  yields  in  his  particular  case. 
The  United  States  Department  of  Agriculture  in  its  reports 
has  frequently  claimed  that  the  enormous  expenditure  of  public 
money  involved  in  its  operations  is  more  than  justified  by 
practical  benefits  which  it  would  be  impossible  to  obtain  through
