BAKU ALA RIDGE. 123 



higher angles; but a little further away, assuming the usually hio-h 

 dips of the southern side of the ridge. These sandstones become cono-lo- 

 meratie with silicious and limestone pebbles, and are overlaid by a broad 

 belt of bright red clays with fewer sandstone bands. (See fig. 9, PI. XI.) 



Diljaba mountain, the south-western termination of the Bakrala 

 _^ ridge, is much more lofty than any other portion 



of it, having a summit elevation of three thousand 

 and fifty-two feet. From the abruptness of its north-west scarp and 

 the occurrence of some of the tertiary sandstones close beneath this, the 

 mountain appears to have been separated from the rocks of the low country 

 upon that side by a continuation of the fracture or fractures seen in the 

 Ghoragali gorge. Having passed the thick covering of detritus close 

 to the foot of the escarpment, the dull reddish-purple sandstones of the 

 group No. 2 in the table are exposed. Over these comes the dark shaly 

 zone No. 3, surmounted by the strong magnesian sandstone group, 

 overlying which is the red and greenish, flaggy, '' salt-pseudomorph 

 zone.^^ This is succeeded by the conglomeratic beds and sandstones of 

 the ^' olive group,^' here containing the remains of Ostrece, and passing 

 beneath the lower beds of the nummulitic limestone, the talus of which 

 probably conceals the coaly shales frequently occurring at that horizon. 

 The stronger beds form cliff-benches, and the ground is in places covered 

 with sunhetta jungle, so that the section is obscured, or is concealed by 

 detrital accumulations on the benches, but can still be made out. The 

 nummulitic Hmestone, just on the ridge, is flat or gently undulating, 

 averaging from fifty to a hundred feet in thickness ; but almost immedi- 

 ately commences to descend the south-eastern 

 South-eastern slopes. 



slopes of the hill with a rapidly increasing dip, 

 The very summit is formed of the lowest beds of the tertiary sandstone 

 lying conformably upon the limestone and stretching up the steep south- 

 eastern sides of the mountain in great sheets, which, placed almost on 

 edge, form ground too steep for cattle or almost for goats to frequent, 

 and consequently a favourite haunt for the " Ooriar,^^ " Meroo,"
