TALCHTK SEKIES. 7 



The Boodah nuddee is joined by a tributary north of Gobinpoor, 

 in which the sandstones just mentioned are exhibited from top to bottom. 

 The varieties of colours which they present are most striking ; and many 

 of them being ribboned, they produce, when properly selected and well 

 arranged, a most pleasing eflect. At present (1866) these sandstones are 

 being quarried to a considerable extent for flooring-stones in the barracks 

 at Hazareebagh. 



Mr. Williams, when speaking of the Talchirs in this part of the field, 

 assigns to them a thickness of 1,000 feet. This is far too much, the 

 beds are rolled in several instances, and so become repeated. The dips, 

 generally speaking, are slight, but they vary up to 8°, 14°, and even 25' 

 near the boundary. 



The structure of the series is very simple, and agrees, on the whole, 

 with the section seen in the Jummoonee in the Jherria field. The 

 following" tabulation shows the order and succession of the beds of which 

 it is composed (ascending) : — 



1. At the base, conglomerate, 



2. Fine-grained sandstones witli occasional bands of conglomerate. 



3. Fine-grained sandstones, of varying colours, with intercalated beds of 



' needle-shales.' These make up nearly the entire series. 



4. Fine-grained sandstones, and one or two conglomerate bands. 



5. Fine-grained massively bedded sandstones. 



Some of the boulders in the conglomerate resting upon the meta- 

 morphics are of enormous size. One of the largest which I measured 

 was 42 feet in circumference. Outliers occur beyond the limits of the 

 field in the western portion of our area, just as they do along the 

 northern boundary. They rarely consist of more than the conglomerate 

 which forms the base of the group. 



The lithology of the Talchirs has been so often described, and 



their characters go often dwelt upon, that I
