Low Water (see fig. 6) is a tarn 1786 feet above sea-level, imme-

 and is certainly so 

 for some distance 

 near the margin. 

 No rock is seen in

 of a former valley 

 to the south of the 

 present one which 

 joined it at no great 

 distance beneath 

 the present exit 

 from the tarn. This 

 valley is moraine- 

 filled, and in it is 

 situated another 

 small tarn, about 

 15 yards across 

 and quite shallow 

 (nearly filled up 

 with vegetation), 

 which lies in a *'- : /'f/A'' "*..*•'

Goatswater is a small tarn lying between the Old Man and Doe 

 Crags. I did not visit it this year, as my recollections of former 

 visits were fully confirmed by an examination from above. The 

 valley is blocked by the screes (probably at one time assisted by 

 material sliding down snow-slopes) which have fallen from Doe 

 Crags and from the cliffs on the other side of the tarn. These 

 screes are most marked at the exit of the tarn, but they are gradually 

 filling up the tarn itself. 



Blind Tarn, farther south, at a height of 1840 feet, has no exit, 

 from which circumstance it derives its name. There are indications 

 of a former stream-valley (now dry) beneath it. This valley has 

 been blocked by moraine, or, to speak more exactly, by snow-slope 

 screes falling from the cliffs above. 



Seathwaite Tarn, on the west side of the Old Man range, is a
