Experiments on Steam Flowjhs, with Fowler^s Plough, at Boxted Lodge, 

 August, 1856. 



Length of furrow 506 yards. 



Width of land taken hy the plough (carrying 4 shares) . . Ig .. 



h. m. sec. 



Commenced experiments 1 20 p.m. 



Finished do 2 38 21 ,, 



Time lost in lacing straps of dynamometer .. .. 12 12 ,, 

 (This occurred in experiment No. 2.) 



Time expended solely in experiments 1 6 9 



Time the plough moved 49-58 



Time taken to shift anchors, &c 16-11 



Quantity of land ploughed per hour, 3 rood 1 p. 4 yd. = -842 acre. 



Power taken. Average 21*28 horse. 



COST PER ACRE. 



Cost of Coal. — The consumption of coals, taking the average 

 of the engines tried at Carlisle in 1855, was 5*719 lbs. per 

 horse per hour, and 4 lb. per horse getting up steam. Hence 



H.-p. hours. lbs. H.-p. lbs. lbs. cwt. qr. lbs. 



21-28 X 10 X 5-719 + 21-28 X 4 = 1302 = 11 2 14, 



say at 20s. per ton, will cost Hi. 7^i. or lo'J^d. for 10 hours 



working and getting up steam, ploughing 8-42 acres in d. 



that time = 16-56 per acre. 



Labour arul Oil. — Engineer at 4s. per day, 4 men assistants 



at 2a-. each, 1 boy Is., oil, &c., Is 19-95 ,, 



Wa<(;r.— 2 horses at 10s. ; 2 boys 2s 17-1 ,, 



Interest and Wear and Tear. — A farm of COO acres arable has 

 looo to be ploughed annually. Cost of machinery 5.50/., at 

 15 percent, interest, and wear and tear, 82/. 10s. = Is. 7^/. 19- 75 , ,

Removal, say once for 16 acres. — 4 horses, 1 man, i day 1 1

17 6 = 13-125 ,, 



(Size of fields averaging IC acres) 86-485 



= 7s. 2^(/. per acre nearly.
