THE FATJNAL POSITION 
shoulder of Ben Chaoran. Thence it continues along the sky-line 
to Meall-a-chuail, overlooking Loch Griam, and across the high- 
road between Lochs Merkland and More, and, mounting the 
shoulder of Ben Hee, turns abruptly from a hitherto northerly 
course to one almost south-east. Up to this turning-point it has 
separated the water systems of Moray in the east from West 
Eoss, but if we follow it now in its eastward progress we find that 
it separates the water systems of Moray and Sutherland, or the 
rivers which run south to the Moray Firth, from those which run 
north to the Pentland Firth. Before following this line, however, 
we will notice the spur which separates the water systems of West 
Eoss and Sutherland. From a point on the forest road which 
leads close past Ben Hee towards Goberneasgach shooting-lodge, a 
sinuous sky-line passes among the great hills of the Eeay Forest, 
skirting the summit ridge of Sabhal Bheag and Sabhal Mohr, and 
then keeping down the left of the Dionard basin crosses the high- 
road near Gualin shooting-lodge, close to Lochan-tarbhach-more, 
and thence pursues an almost direct and straight line to Cape 
Wrath, its elevation gradually lessening after passing the summit 
ridge of Craig Eiabhach (1590 feet), until at Cape Wrath it passes 
out at the cliff edge at an elevation of only 370 feet. 
The south-easterly course of the watershed separating the 
"Moray" and " Sutherland" faunal areas continues in a somewhat 
irregular line towards the Crask Inn, on the high-road between 
Lairg and Altnaharrow. Thence it follows the sky-line or higher 
ridges of Ben Armine, turning northwards between Lochs-na-choir 
and Badenloch, near the sources of the river Helmsdale. Then its 
course is again easterly by Ben Eossal and Ben Vaddu to the 
Highland Eailway at Forsinard, after which it follows the county 
march between Sutherland and Caithness south-eastwards to the 
coast above Helmsdale. 
We do not intend to insist upon the faunal importance of the 
three areas of which our district claims so large a share ; but as 
these watersheds do occur frequently at high elevations, and as 
climatic change, temperature, and soil are in no small degree 
co-existent, and as geological considerations cannot be overlooked.
