[no. 4, new series, 
From a few samples I have seen of various stones said to have been 
brought from the Oodagherry Talook ; and from the report of Natives, I 
shovdd consider that the country in that direction was far superior to the 
country about here, in a geological point of view. Some of the stones 
which are said to come from Oodagherry, certainly look very like ordi- 
nary mountain lime : but as I am at present without any of the various 
chemicals requisite for proving limestone, I arrf'vmable to speak positively 
on the point. 
* * * Upon shov.'ing a small piece of " Blue Mountain limestone," 
which I generally carry about in my poc«ltet, to a Native while out ex- 
ploring about nine miles West of the town he informed me, that he had 
seen stone of the same " caste," either in the hills between Dootaloor and 
Oodagherry or in the mountains, West of latter town ; and that it was ge- 
nerally used for making images, and pillars of small temples." 
We have much pleasure in subjoining the following Report by 
Mr. Wall, the Mineral Viewer, upon the several specimens forward- 
ed by Mr. Powell. 
The minerals are chiefly of volcanic origin, consisting of specimens of 
chrystallized schorl and mica ; there are also several pieces of sedimenta- 
ry rocks, micaceous sandstones and cherts, ferruginous sandstone, two or 
three pieces of chert, probably silicified wood, and samples of nodular 
limestone or kunkur. 
The series indicate a volcanic district with sedimentary deposits, the de- 
bris of those in the neighbourhood ; none are at all connected with the oc- 
currence of coal. The black substance looked upon by Mr. Powell as coal 
is schorl, this substance is readily distinguished from coal by its non-com- 
bustible properties. 
Besides the minerals enumerated above there is a combustible substance 
amongst them, asphaltum, this differs much in appearance from coal and 
when heat is applied to it, it will be found to melt very readily. 
The following is a list of the minerals forwarded : — 
Volcanic Rocks. 
Chrystallized schorl. 
Do. mica black and white. 
Schorl and mica imbedded in compact quartz. 
Granular quartz. 
Varieties of granite in a state of decomposition. 
Kaolin or decomposed felspar.
