BATHYMETRICAL SURVEY OF 
Loch a’ Bliarpa (see Plate LXXL). — A loch draining into the head 
of Loch Eport, between Lochs nan Eun and Tormasacl. 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 1J° 
per foot of depth, as shown in the following table : —

Loch Tarruinn an Eithir (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 Sunder Basin. — This also contains only two lochs wLich were 
surveyed. Lochs Hunder and a’ Chonnachair. The lower loch is joined to 
a branch of Loch Ejiort on its north side. 
Loch a' Chonnachair (see Plate LXXVII.), though draining through 
Loch Hunder into Loch Eport, is situated close to Lochmaddy. It is of
