THE FARMER'S INCOME 633 



poultry, honey and wax, and domestic animals sold and slaugh- 

 tered, with the exception of the milk and cream consumed on 

 the farm where it is produced. This latter item is not given 

 in the census returns. Whatever its value it should be added to 

 the farm income. 



The farm is also credited in the table with the total value of 

 all the crops produced except that part fed to live stock. This 

 valuation is arrived at in the following manner : 



The amount of corn, oats, barley, hay, and forage sold is 

 deducted from the total value of these crops, it being assumed 

 that the remainder is fed on the place and accounted for in the 

 live-stock product listed earlier in the table. The value of that 

 portion of these crops which is fed to live stock is then deducted 

 from the total value of all the crops, the remainder being credited 

 to the farm. The farm is thus credited with the butter, cheese, 

 eggs, poultry, honey, meat, fruits, vegetables, bread, etc., con- 

 sumed on the farm where it is produced, and the value of these 

 products thus consumed on the farm is included in the farm 

 income. 



As stated already, any income the farmer may secure by work 

 done outside his farm or from any other outside source is to be 

 added to the net income given in the table. 



EXPENSES 



The only important item of expense not enumerated in the 

 table is the sum expended annually in the purchase of live stock. 

 Of the other expense items the amount for labor, fertilizers, and 

 feed are given directly in the census returns. 



The expense for the maintenance of buildings is placed at 

 5 per cent of the value of the buildings. This is only an estimate, 

 but it is based on rather extensive investigations by the Office of 

 Farm Management and is believed to be approximately correct. 



The cost of maintenance (including repairs) of implements and 

 machinery is placed at 20 per cent of their cash value. This 

 estimate is based on extensive investigations by the Office of 

 Farm Management and agrees with the estimate in Warren's
