is always doubtful whether the portions exposed on the spurs and lower 

 eminences are ew sitic or not. 



In the Samli hills, south of Sardi and near Morghaug, the talus of the 

 nummulitic limestone cliffs conceals the beds 

 immediately below them ; but a thick band of lilac 

 and variegated clay, very characteristic of the upper part o£ the '^speckled 

 sandstone" group (No. 5) is exposed to a depth of 150 feet, and is even 

 thicker to the westward near Matan. Beneath this are fully 300 feet of 

 the speckled reddish sandstones, some of which are used for mill-stones, 

 they are less alternated with red shale bands than to the eastward ; a 

 few of the rocks are white and conglomeratic, with hard quartzose and 

 crystalline-rock pebbles, and ripple-marks are very common on the sur- 

 faces of the finer beds. 



The magnesian sandstone group is also represented by about 150 feet 

 of light-coloured sandstones and darker shales, overlying a black shaly 

 zone of 90 feet, representing the silurian band. Under this are 300 feet 

 of the purple sandstone series, and then, at the base of all, the salt-marl 

 is seen. 



In this neghbourhood, the rocks beyond the escarpment have a slight 

 „ , t d" to- tendency to dip towards the plains, but they have 

 wards plain. ^11 been SO affected by slips that this appear- 



ance cannot be trusted as original. Over the lower hills, the harder 

 grey sandstones and their fragments are more exposed than in the cliffs, 

 while great masses of the nummulitic limestone and other beds have 

 been transplaced, in some instances having slipped down to the very 

 foot of the hills (see Bg. 29, Plate XIX). 



The red marl is seldom seen on the outer sides of these land-slips, along 



the edge of the boulder-zone, but appears in the valleys between the fallen 



masses. The lines along which these slips have 



an -s ps, taken place, though apparent enough upon the sur- 



face, can seldom be followed downwards so as to discover their " hade ''
