22 KING: KADAPAH AND KARNÜL FORMATIONS. [PART i. 
The reader may now possibly make out from the foregoing descrip- 
ی‎ ot tions that any section run across this area of 
CORLEY country would present a tolerably general form of 
outline. Thus, starting from the sea-ward side, a run of low country 
(the Nellore District) up to a ridge of hills (the Yellacondas) ; then, with 
increasing elevation, a short series of flats with separating ridges? 
succeeded by a mountain range (the Nullamullays), beyond which comes 
a wide depression (to the north of Cuddapah, the valley of the 
Khoond-air, and the chain of valleys to the south-east of it), which is 
again flanked by a more or less irregular series of elevations (the Yerra- 
mullays and their southern extensions) until the section ends in a 
scarped face to the west, below which is the upland terrace of the edge 
of the Mysore plateau. 
The general elevation of the country showing this east and west 
Cice QUE cues superficial profile never rises over 1,750 feet; but 
O ye there are plateaux, mountain ranges, and peaks 
which are much higher, the loftiest of these last being over 3,000 feet. 
shown bylprd: Perhaps, a few examples of profile sections, like‏ و 
file sections. the general one sketched in the last paragraph,‏ 
may best illustrate the different elevations of the country. The accom-‏ 
panying sections (Fig. 1, Nos. 1, 2, 3, 4) are taken across the most illus-‏ 
trative parts of the area, and are at right angles to the longitudinal‏ 
axis; while north and south sections may be easily built up by the‏ 
reader from these and from the map of the country which accompanies‏ 
the present report.
