In the conglomerates are limt^stoue boulders, holding fragments of Trilobites of the genixs Solenople/ini and otlier fossils; but these seem to be of Lower Cambrian age, or considerably older than the beds in which they occur. There can be no doubt, from the stratigraphical position of these beds, that they belong to the Quebec group of Sir W. E. Logan. This is, however, now known to include, on the Lower L>t. Lawrence, beds ranging from the Calciferous (Tremadoc) to the Trenton (Bala), and the beds are so much plicated that it is often dilhcvxlt to unravel their complexities of arrangement.
