It will be my object to show in this series of papers, not only that the absence of the climatic and atmospheric conditions essential to organic life as we understand it, must have rendered the previous existence of any living beings impossible, but also that the completeness of the Animal Kingdom in those deposits where we first find organic remains, its intelligible and coherent connection with the successive creations of all geological times and with the animals now living, affords the strongest internal evidence that we have indeed found in the lower Silurian formations, immediately following the Azoic, the beginning of life upon earth.
In the European ocean of the Azoic epoch we find five islands of considerable size. The largest of these is at the North. Scandinavia had even then almost her present outlines; for Norway, Sweden, Finland, and Lapland, all of which are chiefly granitic in character, were among the first lands to be raised.
Now, most of these Canadian rivers are Azoic in character; hence their grim and formidable beauty. But my river has nothing the least Azoic about it. It belongs to a more recent, a more comfortable, more placid, more satisfying a formation. It is as idyllic a stream as any English one that Tennyson noted in a contemplative ramble to work up later into the "Brook."
At what rate these materials would be distributed and precipitated in regular strata it is impossible to determine; but that volcanic materials were so deposited in layers is evident from the relative position of the earliest rocks. I have already spoken of the innumerable chimneys perforating the Azoic beds, narrow outlets of Plutonic rock, protruding through the earliest strata.

Lawrence, with the grim Azoic rocks, the turbulent rapids and the somber pines. What a superb river system it is! Tell them off on your fingers and you'll have to go on borrowing from them afterwards and then all over again. Think of all those rivers that cluster in the French Canada and feed the mighty Gulf of St. Lawrence.
To crown all, the work of separation wrought so surely, yet so slowly, by the hand of Time, is now reversed in our own day, and "Manahatta" and "Seawanhaka" are joined again, as once they were before the dawn of life in the far azoic ages. "It is done! Clang of bell and roar of gun Send the tidings up and down. How the belfries rock and reel!
In the Silurian epoch following the Azoic we have the first beach on which any life stirred; it extended along the base of the Azoic beds, widening by its extensive deposits the narrow strip of land already upheaved. I propose ... to invite my readers to a stroll with me along that beach. With what interest do we look upon any relic of early human history!
The Laurentian rocks were at first spoken of as representing "Azoic" time; but in 1846 Dawson found a formation deep in their midst which was believed to b e the fossil relic of a very low form of life, and after that it became customary to speak of the system as "Eozoic."
The past is in the hills, the true, the only "everlasting hills of time"; for they are of the old, the immeasurably old, azoic rock of the Laurentians, which forms the roots of other mountains, and which here alone appears to-day, on the face of a young Earth, the same as at the birth of Life itself.
