THE SAGAR DISTRICT. 53 



about the central point of Sdgar is from 1800 to 2500 feet, and that in 

 a northerly direction the land declines considerably,^ — and much more in 

 that direction than it*does towards the east or towards the west. In addi- 

 tion, if it be observed that the primitive range skirting the alluvium of the 

 Nennada, south of Hasmiabad, was found to be on a general equality as 

 to heighth, with the trap and sand-stone rocks of Sugar, whilst the granite 

 range of Bundelkhand, on the northern limits, is at least 1000 feet lower than 

 those rocks of Sdgar, si point nearly midway between the two-named pri- 

 mitive ranges, all is said, it is hoped, that need be, to assist the idea as 

 to what is the general elevation above the level of the sea of the trap and 

 sand-stone under review. 



There exists so strong a family likeness between all the trap rocks of 

 this formation, that it may safely be said, was chemical analysis resorted 

 to, a nearly similar result would, in almost every case, be obtained. It 

 is always every where an earthy homogeneous deposit, by which is to be 

 inferred that there does not occur in it any rock of a definite, or nearly 

 approaching to a definite, crystalline structure : neither a coarse-grained 

 basalt will be found, nor a syenite, nor a green-stone, shewing distinctly 

 its constituent simple minerals, nor is there indeed either a clink-stone or 

 clay-stone. It appears as a closely allied family of basalts of a very fine 

 grain, of wackens and amygdaloids, all others, of the long list of trappean 

 rocks, may be thrown out of consideration, as of no alliance and of no 

 occurrence here. 



No. 1. — Of the few varieties there is one basalt which has been said* 

 to be similar to the Roivleij Rag, and it certainly does agree very closely 



with
