GRAIN FARMING IN NORTH DAKOTA. 35 
The increase in the value of farm machinery is 40 per cent, but ad- 
ditional information (1918) indicates that even greater advances 
have been made. 
Concerning work stock, feed costs are the only costs that have ad- 
vanced recently, so that depreciation in work stock may be considered 
as indicated on page 15. The difference in annual cost of work stock 
between $105 and $145 represents the increased cost of feed.
