200 BATHYMETRICAL SURVEY OF 



Locli a 1 Bharpa (see Plate LXXL). A locb draining into the head 

 of Loch Eport, between Lochs nan Eun and Tormasad. It is fully a mile 

 long, by nearly half a mile in greatest breadth. The western half is 

 narrow and shallow, with several narrow inlets. The eastern half is 

 expanded and forms a simple basin of some depth. The 10-feet and 

 20-feet contours follow the shore-line. The area over 30 feet in depth is 

 narrow, occupies the centre of the loch, and is divided into two parts, with 

 maxima of 35 and 37 feet. 



Loch a' Buaille (see Plate LXX.). Loch a' Buaille, on the north side 

 of Loch Eport, between that loch and Loch Scadavay, is half a mile long, 

 but exceedingly narrow. It is shallow on the whole, but depths occur of 14 

 feet near the south end, and 23 feet (the maximum) near the north end. It 

 drains south, through a smaller loch, into Loch Eport. The surface on 

 June 4, 1904, stood 20-35 feet above the sea. The range of temperature 

 was unusually high, amounting to 14J in the 20 feet of water, the fall 

 between the depths of 15 and 20 feet exceeding 7 a fall of nearly lj 

 per foot of depth, as shown in the following table :

Loch Tarruinn an EitJiir (see Plate LXX.). A loch of very irregular 

 form, lying between Loch Eport and the southern extremity of Loch 

 Scadavay. It is half a mile in length by one-third of a mile in greatest 

 breadth, and consists of a number of very narrow branches of little depth- 

 The widest part, in the north, has a heap of stones in the centre. In this 

 part the maximum depth of 23 feet is found. The principal islands are of 

 rock, the shores of rock, mounds of gravel, boulders, and peat. The 

 loch drains directly by a stream some 50 yards long into Oban Sponish, 

 a branch of Loch Eport. The surface on June 4, 1904, was 16*1 feet 

 above sea-level. The temperature had the high range of 14J, as in 

 Loch a' Buaille, and here also the greatest fall was observed between 15 and 

 20 feet, viz. 6, rather less than in Loch a' Buaille, but still exceeding 1 

 per foot of depth :

The Hunder Basin. This also contains only two lochs which were 

 surveyed, Lochs Hunder and a' Chonnachair. The lower loch is joined to 

 a branch of Loch Eport on its north side. 



Loch a' Chonnachair /see Plate LXXVIL), though draining through 

 Loch Hunder into Loch Eport, is situated close to Lochmaddy. It is of
