ing wear and tear, interest, and all expenses, is from fifteen to forty 

 cents per ton per mile. 



By reference to Figure 10 a general idea is conveyed of the working 

 of this system. The distance such a line can work is limited only by 

 the capacity of the power employed and the strength of the rope. Its 

 most economical application would bo for lines of above three miles, but 

 there is no reason why lines of fifteen or twenty miles in length, with 

 the steel wire ropes of the high tensile strength now made, would not 

 work to advantage. 



I conceive this of so much importance to the public generally, espe- 

 cially the mining public, that I ask for it your careful attention. 



It is applicable to many uses other than for conveying ores from the 

 mine to the mill, as for instance: carrying agricultural produce to tho 

 nearest depot, especially to ships in an offing; for conveying coal to gas 

 works, or beets to the sugar mill; for carrying sand or rock to fill 

 embankments, or grade lands; for conveying light material or passen- 

 gers over any difficult road. And it has these advantages: no grading 

 or road building is required; it can work under all circumstances of 

 weather, with great depths of snow on the ground during heavy storms 

 and freshets; it can run constantly without rest, as well during a dark 

 night as a clear day; it can cross deep gorges and chasms; it, can pass 

 around precipitous bluffs and perpendicular cliffs; the rope can never 

 leave the posts or sheaves; it can furnish and transmit power when 

 there, is sufficient descent, by its own gravitation, or by an engine 

 attached to either end. It can be constructed and worked cheaper than 

 any other system or road can be constructed and worked.
