636 D. MILNE HOME ON THE PARALLEL ROADS OF LOCHABER. 
Aneroid) of 1120 feet, 1165 feet, 1175 feet, and 1489 feet above the sea. With 
regard to the uppermost, I extract the following from my notes. “It is com- 
posed of detritus, with boulders on top. At west end it is a terrace nearly 
horizontal, but towards east it separates from hill side and becomes an eskar 
or kaim. The rains and rivulets descending on it from the higher part of the 
hill, may have scooped out the trench along the south side, which lies between 
it and the hill. Towards east, this kaim ceases to be horizontal, and slopes 
down rapidly towards the plain, still retaining the form of a bank.” On the 
top of this highest flat, as well as on the lower flats, there are several large 
boulders. But above the highest flat we saw other boulders on the hiil ata 
distance, which we had no time to visit, apparently about 1800 feet above 
the sea. | 
On a lower part of Spean Valley there are similar banks of detritus up to 
even greater heights. CHAMBERS characterized them as “sea beaches.” Messrs 
JAMIESON and JoLLy look on them as the lateral moraines of a glacier which 
descended from the valleys of the Treig and Laire. I examined several of these 
banks, and agree that they are in no respect “ Parallel Roads.” Mr JoLty in 
his paper admits that they have a great resemblance to ‘“ kaims,”—that is to the 
well-known long banks of gravel which abound elsewhere in Scotland. On Ben 
Chlinaig, at the lower part of Glen Spean, where the valley is exceedingly 
narrow, there are several of these kaim-like banks running along the side of 
the hill. Mr Jouty describes them correctly when he says that these banks 
are continuous only “for short distances.” ‘They are not absolutely 
horizontal, but rise and fall on the hill sides (Jotty MSS. p. 15). One of 
these “ kaim-like banks” on Ben Chlinaig, opposite to Craig Dhu, I found 
by aneroid to be 1253 feet above the sea. I crossed several others up to a 
height of about 1700 feet above the sea. When not horizontal, they seemed to 
slope down slowly towards the east.” 
Between Ben Chlinaig and Loch Treig, there is the wide valley of the Bruach, 
in which there are many eskars or kaims running in various directions. Some of 
them are straight, others are curved. A view of these is attempted to be given in 
fig. 2 (p. 668). There is another long eskar, immediately above Tulloch House, 
which runs on an elevated plateau in a direction north-east and south-west. At 
its lower end, next the River Spean, there is on it a huge boulder, at a height 
of about 1057 feet above the sea. As the general surface of the district rises 
towards the south-west, this eskar rises also and forms a continuous bank, with 
steep sides, for about a quarter of a mile inlength. Its south-west end is 1200 
feet above the sea. The eskar is composed of fine sand and small gravel.* 
* Mr Jamieson admits that in this valley the gravel is water worn. He says “ at a deep section 
of one of these banks at the mouth of Corry Laire, I noticed that the mass consisted of coarse water 
worn gravel, very pebbly; the pebbles indicated a certain amount of water rolling.”
