Company, Limited. Aerial ropeways have been erected at Kandri, 
Mansar, and Ramandrug. Of these the Mansar ropeway has been dis- 
mantled and replaced by a gravity-incline. The Ramandrug one has a 
length of about 2,100 feet with seven supporting trestles, and lowers the 
ore about 750 feet. The details as to these ropeways and inclines will 
be found under the headings of the respective deposits. Occasionally 
ore-shoots have been constructed to facilitate the lowering of ore from 
one level to another, as at Manegaon, worked by the Central India 
Mining Company, Limited. The rails used on the mines are usually 
of 2-foot gauge, but are occasionally of 2' 6" gauge, as on the mines 
of the Central Provinces Prospecting Syndicate. 
Mining tramways and ^ i- i 
railways. several cases light steam tramways or light 
railways have been constructed to connect up 
various mines to the railway systems of the country. An account 
of these is given on page 477. 
On the 2-foot gauge lines laid do^vTi by the mining companies, the trol- 
lies or trucks usually used hold from one to two tons, according to the size 
of truck. The New Mysore Manganese Company, however, is using some 
trucks that hold up to three tons of ore. On the 2' 6" and metre- 
gauge lines constructed by the railway companies, wagons holding 6 to 
16 tons are used. 
Samples for analysis are not always taken from ore stacked at the mine 
Sunplin" mentioned on page 570 ; at some mines the 
ore is never stacked. Thus, at Balaghat, the 
ore receives what cleaning it needs near the working face and is then 
charged into mine trollies and conveyed by a series of tramways and 
inclines to the railway wagons. The ore is sampled by taking some 
ore out of each mine trolly as it passes the manager's bungalow. 
At Kumsi the ore is railed part of the way and carted the remainder. 
The chemist takes his samples from the carts on arrival at Shimoga^. 
I do not propose to give here descriptions of how particular deposits are 
worked. For this I will refer the reader to the fourth part of this 
^'emoir. There he will find, at the end of the description of each deposit, 
an accoimt of the way in which it was being worked at the time of my visit. 
The description given on page 570 applies to most of the deposits. But 
in a few cases the work has been carried out on more elaborate lines ; 
for this attention may be directed to the descriptions of the way in which
