Chap. XXXV. 1 jabalpur: mansakua 
In their report on the iron deposits of this district Messrs. Martin 
and Louis notice this occurience as follows i : — 
' It contains certain small deposits of iron ores which are ditlcrent in every 
sense from those hitherto described ; they consist of a couple of bands of siliceous 
brown hiipniatito, striking about E.-W., and dipping southwards at an angle of 
about (50" into a low ridge some 000 yards long, rising to a height of about 70 feet 
above the surrounding plain. One of these bands seems to be about 40 feet thick 
and the other about 20 feet, but their persistency has not yet been proved. The 
ore as shown by the subjoined analyses, is of inferior quality, though its physical 
condition is .satisfactory.

' The deposit is well situated, being about one mile from the railway line 
over fairly level ground.

'With regard to these Silondi ores, it can only be said that if such a deposit 
were found close to existing iron works, it might possibly prove worth working, 
but under actual conditions, its highly siliceous character and the small quantity 
available deprive it of all value. ' 
Mr. Bose was led to conclude, as a result of his prospecting opera- 
tions, that at one place about 900 feet west of the Mansakra- Silondi 
boundary there were some 9,000 tons of pyrolusite available. In the 
course of their prospecting operations Messrs. Wynne and Jones, work- 
ing for Messrs. Martin and Louis, cut a trench across the ridge at about 
this point. The length of the trench as I saw it was about 206 paces, 
and the width about 7 feet. It is said to have been 10 to .30 feet deep, 
but by the time of my visit had all been filled up, except for the most 
southern 14 paces of it, where the ore exposed was manganese-ore and
