boulder with six sides, girth altogether not quite 60 feet, and 
height 6 feet. Longer axis W.N.W. Height above sea about 
470 feet; a few faint traces of striae running W. by N. 
Nodules seemed similar to, but not quite the same as, those of 
Elgin and Nairn boulders. 
Croy (Tillage). — About J mile to S.W., and 320 feet above sea. 
A mica schist boulder 17 x 9 x 9 feet. Lies on hill sloping to 
N.W. (Convener.) 
A kaim begins here, which said to run eastward through 
counties of Nairn and Elgin for 30 miles. 
A conglomerate boulder called “ Tom Riach ” (Plate, Sketch 
I.), of following dimensions : — West side, 18 feet; north side, 
21 feet; east side, 24 feet ; south side, 21 feet; height, 20 feet, 
it stands in the middle of a plain or flat valley through which 
River Nairn flows. Rocks in situ are gneiss, and boulder appa- 
rently rests on this rock. A small portion of its under surface, 
resting on the rock, visible. It looks smooth, as if it had been 
pushed over the subjacent rocks ; and there seemed grooves or 
scorings which coincided with axis of valley, which here E. and 
W. This boulder must have come from distance, and been 
carried by ice, of some kind. In higher parts of valley in 
which this boulder occurs, conglomerate rocks in situ exist. 
Not probable that this boulder could come from N.W., as in 
that case it would be carried over Culloden Muir, which 300 
feet higher than boulder. Yeiy probable that brought by 
glacier from westward. Ingredients of this conglomerate 
apparently not same as those in Elgin and Nairnshire. 
On high plateau, 4 miles south of Inverness, at height of 
about 774 feet above sea, another conglomerate boulder, with 
a thin stratum of old red sandstone on top. Grirth about 51 
feet. Height, 9 feet. Longer axis N. and S. Kaim of gravel 
and sand to N. of boulder, about 900 feet above sea, running E. 
and W. being direction parallel with valley of Nairn. (These 
boulders shown to Convener by Mr Jolly, Inverness.) 
Dallanossie (Parish). — Moy Hall estate, Eallry farm, Mr Eraser, 
tenant. Boulder, 30 x 18 x 9 feet, apparently a bastard granite; 
though rocks of adjoining district are also granitic, the boulder 
much darker in colour. Nearest rock in situ S.W. by S. about
