Formulas for calculating' interest on farm equipment, W. J. Spiixman 

 (U. S. Dept, Agr., Office Sec. Circ. 53 {1915), pp. 4)- — The author believes that 

 interest should be charged on that part of the original cost represented by the 

 estimated length of the original life of the machine yet available. The total 

 interest charge would be one-half the product of the cost of the machine by the 

 interest rate and the number of years of life of the machine plus one. The 

 average interest cost can be obtained by dividing the total interest charge by 

 the number of years in the life of the machine.
