through a chasm of two hundred yards, in one suc- 

 cession of cascades, rapids, and caldrons. For a 

 great part of this length it is at such a depth, and 

 the rocks so nearly meet over it, that it is not possi- 

 ble to see the water, though it announces its presence 

 hy a noise that stuns the ear. One of the caldrons, 

 haying a noise something like that of a mill, is called 

 the Devil's Mill, because it is at work on Sundays 

 as well as on lawful days. On the lower part of the 

 chasm are two bridges a new and an old one. A 

 little above this is the Crook of Devon, where the 

 river makes a remarkably acute angle ; having pre- 

 viously run in a glen of the Ochills, of the most 

 picturesque beauty, in a direction towards the north- 

 east, it suddenly turns and runs by the base of the 

 same hills, in a south-westerly course, so that, 

 though it runs nearly forty miles, the direct distance 

 from its source to the point where it joins the Forth 

 is little more than five miles.
