EXCURSION XV. 181 



marly, attended by the appearance of great dikes of basalt; 

 the stream, issuing by a narrow opening and liable to great 

 floods, would readily disintegrate and sweep off the materials 

 of these fractured beds. The part most deeply imbayed is 

 that immediately opposite the entrance of the stream and its 

 tributary into the existing hollow, below Kilmorie Church ; 

 from this the sweeping currents would be reflected to the 

 heights north of the inn, and thence again towards the point 

 where the stream escapes. The principal dikes fcre at this 

 point, below the bridge. The largest is thirty to forty feet 

 wide, ranges nearly N., and forms the high cliff over the 

 flower-garden; another, farther S., is ten feet broad, and 

 ranges nearly N.E.; a third, nine to twelve feet wide, ranges 

 N. 10 E., and dips W. at 80. Above the bridge there are 

 two large dikes; the lesser stands high above the south bank 

 of the stream, like the side of a former dam, and is seen on 

 the north side in contact with disturbed and altered sand- 

 stone width twenty-five to thirty feet, range N. 26 W., 

 dip E. at 70; the greater, farther up the stream, is thirty- 

 five to forty feet wide, and ranges N. 5 E. The sandstone 

 strata in the hollow dip usually about S. 10 to 20 W., at 

 angles varying from 20 to 30; but there is considerable 

 disturbance. The heights round the basin vary from fifty to 

 seventy feet above the stream. 



85. The beds of Arctic shells most accessible from Lag, 

 and the most satisfactory to examine, are about three- 

 quarters of a mile distant, and on the banks of a tributary 

 to Torlin Water, called the Cloinid or Clenid burn. It 

 joins the Torlin on its right or west bank, a little way N.E. of 

 Lag Inn, coming down from the north-west through a deep 

 rocky gorge, easily passable when the water is low. Another 

 way to reach them is to follow the high road as far as a lane 

 near the Kilmorie school-house, pass by this to the river, over 

 which there is a wooden foot- way, and then to cross the 

 fields, by a cottage on the high bank opposite the church, 

 down into the channel of the Cloinid burn. We are thus
