BULLETIN 304, U. S. DEPARTMENT OF AGRICULTURE. 
a greater proportion of hill water than others, the cost has been shown 
for the assessable area and for the total drainage area of each dis- 
trict. The tables state the number of years of operation the cost 
figures cover, and if not otherwise stated, 1914 is the last year in- 
cluded. Table 13 is for steam-driven plants and Table 14 for elec- 
trically-driven plants. 
It will be noted that the average yearly cost per acre of total 
drainage area for the steam-driven plants is SO. 43, and that the 
variation in cost is from a maximum of SO. 93 for the Coal Creek 
District to a minimum of $0.15 for the Des Moines County No. 1 
District. Of course, great variations in the amount of water pumped 
and in other local conditions tend to affect the relative costs for the 
various plants. Where the pumps are driven by motors the average 
yearly cost per acre of drainage area is $0.88, with a maximum of 
$1.07 for the Pekin-La Marsh District and a minimum of $0.63 for 
the Big Swan District.
