Pettidale Water. 



(Examined April 23rd 1897.) 



Examined about 2 p.m., weather fine. Granite rocks fringe the shore ; 

 the north end of the Buirgs " forms one side, the other being broken 

 ground, with moss and heather. Animalcule seemed scarce and minute. 

 The loch has an altitude of between 400 and 500 feet. 



Innis Loch. 



(Examined April 23rd 1897.) 



This is a small, shallow-margined pool, with a good deal of mossy sedi- 

 ment about the sides and bottom, and with a number of watercourses 

 draining into it from the gently sloping surrounding ground. The banks 

 were high and steep, which rendered the work of examination rather 

 difficult. 



(3) Bressay. 

 Loch of Kirkabister. 

 (Examined May 15th 1897.) 



Examined about 4 p.m., the day being mild and warm. This is a 

 rather small and shallow lochj lying half-way between the beach of Ham 

 and Bressay Lighthouse, and about 48 feet above sea-level. The bottom 

 and sides are boggy, especially the southern shore, which was so soft and 

 spongy as to be unapproachable. Some algae were growing all round the 

 loch, and fauna seemed plentiful, the hand-net being used round the 

 whole of the loch except the southern shore. 



(4) Lochs in Yell. 



Lochs of Colvister. 



(Examined June 4th 1897.) 



This large, irregularly-shaped loch was examined about 5 p.m., under 

 favourable atmospheric conditions. The hand-net was used all along the 

 north-eastern shores, which are rocky or gravelly, with very little vegeta- 

 tion. The outlet is by a burn that flows eastwards into Bastavoe. Its 

 altitude is 71 feet. 



Loch of Lumbister, Yell. 



(Examined June 4th 1897.) 



The examination of this loch, which was made between 6 and 7 p.m., 

 was confined to the eastern end, where the shores and bottom are covered 

 with fine red sand. The water is clear, and the loch has a pretty 

 appearance. Very little plant life was visible, and fauna did not seem 

 to be so numerous as in the neighbouring loch of Colvister ; but as the 

 loch is a large one, the examination could not be regarded as very 

 complete or satisfactory. It is 64 feet above the level of the sea, and a 

 burn flows westwards fyom it into Whalfirth.
