Report on Steam Cultivation. 



197 



As plougli-ropes are subject to much friction, and the lar2:er 

 the wire the more friction the rope will stand, the wires should 

 be as lar2:e as the sheaves and drum will permit, and the latter 

 should afford space enough to admit of the rope being made with 

 four strands. 



Again, if very small sheaves and drum be used, the constant 

 quick bending, in coiling off and on, will cause the rope to 

 wear out much sooner than it would were the sheaves and drum 

 of a larger size. 



The ropes in the greatest demand as being suitable for most 

 kinds of ploughing are made of No. 15 gauge wire, with six 

 wires in each strand, and four strands in the rope. 



The principal sizes used are as under : — 



The price of these ropes would be 755. per cwt., delivered 

 carriage paid. 



The subject of " depreciation in value " of apparatus may be 

 studied in the data furnished in the Reports of the steam culture 

 of Mr. J. L. King, of Scole (No. 20), and others. 



As an illustration of the relative extent to which some farmers 

 use their steam apparatus more than others, we give the number 

 of acres to each pair of horses still kept in conjunction with 

 steam in a variety of instances. 



Thus in our light-land section — Mr. Ellman has a pair of horses 

 to each 70 acres; Mr. Lancashire, to 100 acres; Mr. Arnot, 

 to 132 acres arable ; Mr. Smythe, to 100 acres ; and Mr. Woods, 

 to 50 acres arable. 



On medium soil — Mr. J. L. King has a pair of horses to 

 each 75 acres arable ; Mr. Greene, to 133 acres ; Mr. Palmer, to 

 66 acres ; Mr. Battcock, to 70 acres ; Mr. Ruston, to 80 acres ; 

 Mr. Bott, to 84 acres ; and Mr. Cooper, to 90 acres. Mr. Cooper, 

 before the steam cultivation came, had a pair to every 60 acres.
