One large boulder angular, 16 x 14 x 7 feet, named “ Clach 
Chinean,” or “ Stone of Doom.” These boulders all rest on 
heaps of drift, much resembling a moraine. On the opposite 
or south side of the valley there are similar masses of drift, 
containing, however, stratified beds of sand and gravel. 
2. About 2 miles north of Tullypowrie village, near the hills, 
two very large boulders of mica slate occur, about 1500 feet 
above sea. They rest apparently on a heap of drift. They 
are both cubical in form, and with sharp angles, as if never 
exposed to friction. One of them measured, and found to be 
71 feet in girth and 17 feet high. The hills are more than J 
mile distant. They must have been brought by ice of some 
kind, and let down without violence ; for a fall from any height 
would have probably caused such large masses to break in 
pieces. The adjoining hills form a range to N. and W., reach- 
ing fully 700 feet above the boulders. But to N.W. (magn.) 
of the boulders, and within a J mile a passage occurs through 
the hills, the level of which is only about 200 feet above the 
boulders. They might have come through this passage, carry- 
ing the boulders and stranding them where they now lie. 
These boulders, called “ Clach M‘had,” or “ Stones of the 
Fox.” 
3. Above Pitnacree House, a boulder of schist resembling 
hypersthene, 15 x 111 x 4 feet above ground. It is called 
“ Clack odhar,” or “ Dun Stone.” No hills are near it, and 
it differs from all rocks in situ near it. (Reporter — Mr 
M‘Naughton, merchant, Tullypowrie).
