I examined the section at Drummore, and found that it exhibited 
a considerable depth of sand, beneath which the shells occurred 
in a bed of blue clay. Similar shells in similar blue clay are found 
near the sea coast at Ardersier, Fort George, about 8 miles due 
north from Drummore of Clava, and at an elevation of about 50 
feet. It is evident from the occurrence of these shells in two 
separate localities, that this part of Scotland had once been covered 
by a sea of a temperature similar to that now washing the coasts of 
Arctic America, Finmark, and Spitzbergen. I also inspected 
the two famous boulders of the district, both of them huge con- 
glomerate blocks, “ Tom Riach ” (the stone of the grey hill), 
measuring 27 feet x 22 feet x 15 feet, near Croygorstan, and the 
11 Duke of Cumberland's stone ” on Culloden Moor.* Probably 
neither of these are far travelled, conglomerate rocks being found 
in situ in proximity to them. The valuable papers by Messrs. 
Thomas D. Wallace and James Fraser of Inverness, in volumes 
III. and IY. of the Edinburgh Geological Society's Transactions , 
treat fully of the Boulder phenomena and geology of this interest- 
ing district.

1. Split conglomerate boulder, in the burn below Mid-Lairg 
Farm, in Upper Strathnairn. 
2. Clach-a-nid (stone of the nest) lies on the U.E. shoulder of 
Meal-Mor, a hill 1207 feet high. The boulder is 950 feet above 
seadevel. It is composed of gneiss, and measures 28 x 24 x 14 feet. 
3. Broivnie Stone. A very large conglomerate boulder lying on 
the moor, half a mile north of Bunachton. 
4. Clach-na-h-ulaidh (stone of the hidden treasure). A large 
block of gneiss, 12x12x5 feet, resting on the brink of a cliff of 
old red sandstone, overhanging the east bank of the Nairn River, 
a few yards from Nairnside House. It is about 40 feet above the 
river, and 400 feet above sea-level. 
5. Gneiss boulder, measuring 6x5x4 feet, much rounded, lies 
* The “ Tom Riach ” boulder is between 300 and 400 feet above the sea-level; 
and the “ Cumberland stone ” is 487 feet above the sea.
