FOR AMERICAN VINES.

joined to it by an iron bar. With an 8 H.P. engine working 

 at 150 revolutions per minute the drum performs eight 

 revolutions, and the cable travels at the rate of 69 feet per 

 minute. 



This machine is simple, strong, well constructed, and works 

 satisfactorily; the only drawback is the difficulty of anchoring 

 the fixed pulley. 



Its cost is 92 without cable or plough. The cable, 0*55 

 inch in diameter, costs 4d. per foot ; the plough, which is 

 the same as for the horse-gin, costs 30. The whole plant, 

 therefore, exclusive of the engine, costs 140. With an 

 8 H.P. engine costing 220 to 240, the whole plant costs 

 360 to 380.
