D. MILNE HOME ON THE PARALLEL ROADS OF LOCHABER. 617 
The Spey valley, from its summit at Lochan Spey down to Kingussie (beyond 
which I have not examined it), shows everywhere similar deposits of drift 
and similar denudation. Though I did not reach a higher level in my survey 
than 1161 feet above the sea, I saw that the+Y was detritus on the hill sides at

least 200 feet higher. The power of a river and its tributaries in scouring out 
a wide district of its detrital covering is well shown in this valley. All along 
the course of the Spey, there are numerous cliffs, at some distance from the river 
and approximatively parallel with it, indicating the high levels at which the 
river formerly ran, and the large amount of materials removed by it. At Garve 
Bridge, 977 feet above the sea, a tributary called the “ Oig” joins the Spey. 
On the right bank of this tributary there are 3 or 4terraces one above another 
(to a height of about 120 feet above the stream), being the different levels at 
which it has successively run. 
At “ Gathbeg” near Laggan Church in Strathspey, cliffs of detritus face the 
river, reaching to about 324 feet above it. Banks and terraces on each side of 
the river continue down to Kingussie. 
These terraces show that at a former period the River Spey in its course 
between Laggan Church and Kingussie, had formerly flowed at least 200 feet 
higher than now, and must have scoured out the wide valley, at the bottom of 
which the town of Kingussie stands. 
There are similar banks on the west side of the river. I could not make out at this second visit, very 
clearly, whether the base of the banks sloped with the river or was horizontal. If horizontal, they would 
of course indicate a lake, with a river running through it. In a higher part of the river, viz., above 
the Roman Catholic Chapel, there are old river cliffs, which show that the river had formerly ran 180 
feet higher than it now runs at that place.
