plutonic rocks, with a few of porphyrite. The pebbles, which are not always well 
bounded, hare a remarkable tendency to arrange themselves in groups in some of the 
^onglojQeratic sandstone beds — a disposition which may possibly bo owing to their 
aving been dropped in heaps from the lloating roots of trees, but much more likely to 
oeir having been dropped from floating ground-ice. Large isolated boulders of granite, 
which could hardly have been brought to their present positions except by glacial 
^tion, occur here and there in the midst of strata of fine sandy or muddy material, 
^''wons of the trunks of coniferous trees are occasionally found lying horizontally in 
strata. 
The bands of ferruginous sandstone are storehouses of marine fossils, which 
°ccur also, though more sparingly, in the shales and grey sandstones. In the latter the 
^ ells are almost always calcareous, and contrast strongly with the siliceous and 
ispathic sandstone matrix. In the ferruginous sandstones, on the other hand, the 
^^ssils are always in the form of casts. About fifty feet of pebbly sandstone strata on 
onehumpy Creek are absolutely crammed with shells, especially Stroplialosia Olarkei, 
ii- Another sandstone bed, at least one hundred feet thick, in the Bowen River, 
^^out two and a quarter miles above the old crossing at Beasley’s, is also full of 
*'opJialosia Clarkei. Derbyia senilis, Phillip.s, is abundant on Coral Creek ; and on 
mean Creek, one mile above the Bowen and Sonoma Road, and near the Diamond 
111 Bore. Froductus, Spirifem, and Martinia are common throughout the whole 
®®ries. Xhe shales and grey sandstones are frequently pierced by rootlets in the 
l^osition of growth. The marine shells prove that the strata were mainly deposited 
y a sea, of which the Clarke Range formed the eastern shore; while the upright 
wets in the grey sandstones and shales indicate the occasional appearance of land 
surfaces.
