LOCHS OF THE LEVEN BASIN. 
The area draining by the river Leven into Loch Leven, a branch of Loch 
Linnhe, is an extensive one, and includes four lochs which were sounded 
by the Lake Survey, viz. Loch a’ Bhaillidh, Lochan na Salach Uidhre, 
Lochan Inbhir, and Loch Eilde Mor (see Index Map, Fig. 6). These 
four lochs receive the drainage from nearly 60 square miles of mountainous 
country, some of the peaks approaching 3000 feet in height, while 
Binnein Mor, to the north-east of Loch Eilde Mor, attains an elevation of 
3700 feet above the sea. Loch Eilde Mor is situated in Inverness-shire, 
draining by the Allt na h-Eilde into the river Leven, while the other three 
lochs lie on the boundary-line between Inverness-shire and Argyllshire, 
and may be looked upon as merely a series of expansions of the river 
Leven. The fishings in the lochs are preserved. 
Loch a Bhaillidh (see Plate XXVI.). — Loch a’ Bhaillidh (or Vallie) 
lies about 6 miles from Rannoch station on the West Highland Railway, 
and equi-distant from Loch Laidon in the Tay basin, and Loch Ossian in 
the Lochy basin. It is irregular in form, trending nearly east and west, and 
exceeding a mile in length, with a maximum breadth of about half a mile, 
the mean breadth being over a quarter of a mile. The loch is comparatively
