haulage is controlled by a brake-gear at the top of the incline, the diame- 
ter of the brake-whoel being {> feet. The vertical drop on this incline is 
lOG feet in a horizontal distance of 750 feet, i.e., the gradient averages 
1 in 7. The capacity of this incline is GOO tons a day, but the amount 
usually transported is less than half this amount. The trucks are then 
run for a short distance along another level with a gradient of 1 in 75, 
past the manager's bungalow to the head of incline No. 1. Another 
gravity incline (No. 3) from the North Bharweli portion of the de2}osit 
feeds, when working, which is only occasionally, about 150 tons a day 
on to the bungalow level. One truck a trip is lowered. The gradient 
is 1 in 5-35, the drop being 58 feet in 300. Thus all the ore from the 
Manegaon, Hirapur, North and South Bharweli, portions of the deposit 
arrives at the top of the incline No. 1. From there the ore is lowered 
down the western slope of the phyllite ridge lying to the west of the ore 
ridge, the bungalow level being on the neck joining the two. The drop 
is 163 feet in 500 horizontal with a very steep gradient (1 in 2-6G at the 
steepest). It is controlled by the usual type of brake-gear, the horizon- 
tal wheel having a diameter of 5i feet ; one truck a trip is lowered, the 
maximum daily capacity being 350-400 tons. As this is not sufficient 
to take all the ore that could be fed to the top of the incHne, another 
incline (No. 4) is being put in alongside of No. 1. It will have the same 
drop, but a less steep gradient, and will be able to lower 2 trucks every 
trip with a daily capacity of 600 tons. The two gravity inclines together 
will then be able to dispose of 950 tons of ore a day as a maximum. 
At the foot of the phyllite ridge the trucks from incline No. 1 are run 
out on rails supported on trestles, and tipped out on to a dumping ground. 
This is at a siding put in by the Bengal-Nagpur Railway. The siding 
is connected by a length of 2 miles of 2' 6" gauge rails to the Gondia- 
Jabalpur branch of the Bengal-Nagpur Railway at a point about a mile 
north of Balaghat station. The ore thus dumped at the mine siding 
is inspected by mates whose special duty it is to reject any ore containing 
quartz or quartzite, such ore not infrequently being put into the bottoms 
of the mine trucks by the mine coolies and covered by the good ore on 
top. The ore is loaded by hand into the railway-wagons. During 
the latter part of 1906 one train a day of 14 wagons, this being the full 
capacity of the siding, was being loaded. Each wagon takes 16 tons 
of ore, giving 224 tons per train. Some 4 or 5 extra trains a month were 
also run, accounting in all for a despatch of some 7,500 tons a month. 
The tonnage of the ore loaded into these wagons is calculated by measure- 
ment, one ton of broken ore being taken as occupying 16 cubic feet.
