consideration of the question, I have no hesitation in asserting that
all the so-called syenite (except some intrusive dykes) is simply a
rather granitoid variety of the Hebridean gneiss, and that its junc-
tion with the calcareous series is a faulted one. The fault descends
the right bank of the vaUey, striking about E.S.E., changes its direc-
tion before reaching the river to a little E. of S., and while crossing it
appears to change again, and emerge, striking about midway between
S.W. and S.S.W. (fig. 1). "^^ " " """ tT.i.,,;^.„ ;.. ..^ i..

foUowed along the hill-side, and traced to within a short distance of
the newer series ; but I could not, though I searched carefully, find an
actual iunction. On this side also I observed a case of very distinct
foliation in the " syenite," dipping at about 45° to S. 20° W. Below
this spot the ordinary Hebridean gneiss can be traced by the river-
side at intervals, obviously forming part of the same series, to a sheep-
fold at the mouth of the glen. It is overlain by Torridon Sandstone,
which occupies, I believe, all the undulating shoulder between the
