56 CHANNELS AND GLENS OF AYRSHIRE. 



Annick Water. — The Annick above Stewarton has scaurs of 

 boulder-clay. It leaves the old valley, and, at the north end of 

 the town, cuts through white crumbling sandstones. The old 

 valley is some distance to the east of the rock-bound cut. Below 

 the town it cuts for a bit into lower limestone strata. 



Fenwick Water. — On the Fenwick ("Finic"), above and below 

 Dalmusternock, there is a thick clay-and-stones deposit over 40 

 feet deep — base not seen. Lower down the burn has cut through 

 rock for a bit, having left the line of the old valley, which is 

 probably further to the east. 



Crawfordland Water. — Some distance below Craigendunton 

 the Crawfordland leaves the old valley and cuts through trap 

 rocks, ash-beds, amygdaloids, and at a small waterfall there is a 

 solid trap-sill in clean-cut columns. At parts the drift is seen on 

 top of the trap — more in force on the south side of the burn — 

 showing that the old glen lies to that side. At Craigendunton 

 Water Works the old glen was got in the puddle trench, with the 

 following section — 



Boulder-clay, up to - - - 40 feet thick. 

 Sand and gravel, 5 „ 



Laminated mud, - - - 3 ,, 



Rock, amygdaloidal trap. 



A considerable quantity of fine water flowed from the sand-bed 

 in the puddle trench, which shews that it (the sand-bed) must 

 extend for some distance, and outcrop from beneath the boulder- 

 clay, probably further up the valley. 



The scenery about Crawfordland Bridge is rather pretty, the 

 stream here having left the line of the old drift-filled glen, and cut 

 mostly through sandstone, the tree-shaded defile with its deep, 

 sullen, rocky pools forming a great contrast to the one-side scaur 



landscape or grass-grown slopes of the " drift " formation. A 



short way below the bridge, a sandstone bed is to be seen which, 

 in a distance of eight yards, thickens from a " knife-edge " up to 

 six feet. 



Hareshawmuir Burn. — This stream leaves the old channel or 

 glen above Langdyke and cuts through various rocks, including a 

 40-yard trap-dyke, not shown on the one inch survey map. On the
