transport by endless rope haulage, sorting belts and tables, which are 

 in common use in South Africa and the United States, have hitherto 

 not been employed at Kolar ; the reason given being the cheapness 

 of native labour. 



Headgears. — The headgears or poppet-heads are usually of wood 

 and are of simple design ; but in the case of the New Vertical shaft at 

 Champion Reef and the New Vertical at Nundydroog they are of steel 

 lattice work (see PL 14). The headgears at Ribblesdale shaft, Mysore 

 Mine (see PL 18), and the Champion Reef New Vertical are 50 and 

 54 feet high, respectively, and are provided with two pairs of 

 pit-head pulleys of 10 feet diameter arranged one above the other, 

 one pair being for the cage-ropes, the other for the skip-ropes, The 

 cages in these shafts are double deckers and are chiefly used for 

 raising and lowering men ; the skips at Ribblesdale shaft have a 

 capacity of from i? tons and at Champion Reef of 2\ tons, and are 

 discharged by bringing them to rest on a moveable lip on the head- 

 gear and then withdrawing a bolt which holds a hinged door on the 

 bottom half of the front part of the skip. At the Nundydroog New 

 Vertical there are no skips, the cages being arranged for the 

 reception of the underground trucks, which are run out and tipped 

 over screens at the shaft-head, 



There are no storage-bins at the vertical shaft-heads, the ore 

 being run from the skips through hoppers into the waggons which 

 convey it to the sorting floors or to the storage-bins. 



Transport. — From the shaft-top the ore is transported in waggons, 

 drawn by hand, by bulls, or by locomotive power. The waggons are 

 of steel and are either side-tipping or have a hinged bottom. 

 Side-tipping waggons carry one ton while the larger size with bottom- 

 discharge have a capacity of 4 tons. The ordinary tramlines for the 

 smaller waggons are laid at a gauge of from 18 inches to 2 feet 6 

 inches, and the rails weigh 14 to 24 lbs. to the yard. The larger lines 

 for locomotive transit are laid either at a 2 feet 6 inches or 3 feet 3 

 inches (metre) gauge, and the rails used weigh 36 lbs. to the yard. 



The system in vogue at the Mysore Mine is as follows : —
