SKETCH OF THE 



which the vertical strata are very generally observed. Still, however, 

 detached groups and hills here and there present themselves. North of 

 Nasirahad, these plains are bounded by the great central range, which 

 here takes a turn to the N. E. — East of Nasirahad, and proceeding from 

 that cantonment through Jaypur towards Biana, we have still the usual 

 level plains with their detached hills and groups. These latter, in many 

 instances, appear to form detached portions of two hill ranges, which we 

 meet with about half-way betwixt Nasirahad and Biana, and which 

 run parallel to, and at no great distance from each other. Frequent 

 secondary ranges pass off from them, generally in pairs, running 

 parallel to each other, and nearly at right angles to the parent ranges. 

 These parallel ranges are separated from each other by perfectly level 

 plains, with the usual detached hills, which are, in this district, generally 

 topped by a fort or a strong-hold, and which rise abruptly from the surface, 

 often exhibiting an almost perpendicular crag. South of the most south- 

 ern of the two ranges above alluded to, we have also plains of large extent, 

 the route in this direction running through the south of AJmer and Jaypur 

 and crossing the fertile jageer of Amir Khan near Tonk. This portion 

 is also characterised by hill groupes and detached ranges, some of consi- 

 derable extent. The height of these detached groupes, hill ranges, &c. is 

 very inconsiderable ; but the plains themselves are situated high above the 

 level of the sea, as may be seen from the measurements made by Captain 

 Dangerfield ; and there appears to be a gradual slope as we proceed east 

 towards Bliaratpur. The hills composing the central range, rise higher, 

 and their altitude appears to become more considerable as we proceed 

 north, — none, however, I believe, rise higher than twelve hundred feet 

 above the level of the plains; very few, indeed, so high, and their 

 general average may be estimated at between six and eight hundred 

 feet.
