Application of Steam Power 
liorses, and- only \hs. by steam. The general average cost of the 
steam-ploughing has been a little over 8s, an acre, yet it is 
2 inches deeper than the farm-teams have hitherto done it. Mr. 
Redman has kept accurate memoranda of all the expenses, &c. ; 
and from these items I have been enabled to form tlie following 
estimate of the expenses for one week : — 
£ s. d. 
Labour— 2 men at 20s 200 
„ 1 man at 12s 0 12 0 
„ 2 lads at 6s 0 12 0 
Water 110 
Coals, 3 tons at 20s., oil, &c 3 3 0 
Eemovals twice a week, each requiring four liorses, 
&c., for a quarter of a day 070 
, 7 15 0 
Wear and tear and interest, say 20 per cent, on the 
first cost of engine, and all the machinery (equal to 
750?.) charged on 200 days in the year 4 10 0 
12 5 0 
£ s. d. 
The working expenses on 30 acres per week arc thus 0 5 2 
Wear and tear, and interest 0 3 0 
0 8 2 
Mr. Fowler's own estimate of the annual cost of keeping the 
apparatus, &c., in complete repair, replacing the wire-rope as it 
wears, &c., is not far different from the above 20 per cent. ; and 
it is based upon very extended experience of such wire-rope and 
machinery : — 
per annmn. 
£ s. d. 
I'enewal of the steel rope per year 35 0 0 
Maintaining the windlass and tackle in order .. 25 0 0 
Ditto boiler and engine .. 15 0 0 
75 0 0 
Contingencies 25 0 0 
Expense of preserving the efficiency of the whole 
machine 100 0 0 
Interest of outlay 5 per cent, on 750Z 37 10 0 
137 10 0* 
* The items of interest, and wear aiul tear, liave lieen coiisideralily lowered 
since the a1)()vc fifrures were calculated, owing to the simpler and cheaper coustruc- 
tion of the apparatus.
