An allowance has been made for fuel used in starting, lubricating 
oil, and supplies, amounting to 25 per cent of the assumed cost of fuel 
oil. While the prices of fuel oils are so unstable these assumed prices

are probably as good as any others. Figure 6 has been arranged with 
oil prices varying from 1 cent to 10 cents per gallon, so that corrections 
may easily be made for changes in fuel costs. 
Figure 7 shows the labor costs per acre per year for pumping plants. 
The basis on which they were computed is shown in Table 41.
