432 LAMLASH. GENERAL DESCRIPTION* 



LAMLASH. 



THIS small island may be considered a dependency of 

 Arran, being associated with it no less in structure than in 

 geographical position. At the same time, it presents some 

 interesting peculiarities requiring notice, while the general 

 simplicity of its arrangement will permit that notice to 

 be very brief. 



It consists of a single mountain rising to the height 

 of 1009 feet, as appeared by the barometrical measure- 

 ment, its length being estimated at a mile and a half, and 

 its breadth at less than half a mile. The surface is gene- 

 rally rocky and covered with luxuriant heath and Arbutus 

 uva ursi; scarcely any grass being found on it, except 

 in the lowest situations. The access to the summit is 

 in general difficult, and the acclivity considerable ; on the 

 eastern side, the mountain is inaccessible; the ground 

 descending rapidly by a succession of precipices and steep 

 slopes. 



Frofn the situation of Lamlash with respect to that 

 sinuosity in Arran which it covers, it forms a convenient 

 and capacious harbour. This is the most frequented of all 

 the harbours in the Clyde ; while from its double entrance, 

 its magnitude, depth of water, and the quality and clean- 

 ness of the ground, it is esteemed one of the best in 

 Britain ; being equally adapted for ships of all burthen, 

 and, from its capacity, adequate to the reception of large 

 fleets. 



The geological resemblance of Lamlash to Arran is 

 limited to that part of the latter island immediately oppo- 

 site, namely, the southern division ; which has been shown 

 to consist of secondary strata covered and intersected by 

 various rocks of the trap family. Like this tract, it con- 

 tains neither granite nor primary strata. 



The sandstone may be seen in different places, and in
