In addition to this expenditure, 10 per cent, on the prime cosfi 
was included in each year's account for depreciation, without, 
however, the residue being regarded as realised profit.; 
The calculation of 10 per cent, was adopted as the '^usual 
allowance made on machinery ; but, as Mr. Wells has well 
shown in his paper on Steam Cultivation,* the agricultural 
locomotive engine is exposed to an unusual amount of wear 
and tear. 
1st. From the horizontal position of the piston, " which, 
without great care, rapidly becomes oval-shaped." 
2ndly. From the concentrated form of the boiler, the tubes 
of which are difficult to clean, and wear rapidly away, 
3rdly. From the injurious effect of bad roads during removals, 
and the constant oscillation of the engine when at work.

of Booth Ferry House, Howden.
