"But even this is nothing compared with the great social and moral effects of this system, a subject admirably treated, in many of its aspects, in a sermon by Dr. Gannett, which has been kindly given to the public. All important also are its political effects in binding the States together as one family, and uniting us to our neighbours as brethren and kinsfolk. I do not know, Sir, [turning to Lord Elgin,] but in this way, from the kindly seeds which have been sown this week, in your visit to Boston, and that of the distinguished gentlemen who have preceded and accompanied you, our children and grandchildren, as long as this great Anglo-Saxon race shall occupy the continent, may reap a harvest worth all the cost which has devolved on this generation." [Cheers.] Other speeches followed, which would not now interest my readers. In due time the assemblage broke up, and the guests streamed away over the lovely Common in all directions, forming even in their departure a wonderful and pleasing spectacle. We Canadians remained in Boston several days, visiting the public institutions, presenting and receiving addresses, and participating in a series of civic pageants, the more enjoyable because to us altogether novel and unprecedented. Our hosts informed us, that they were quite accustomed to and always prepared for such gatherings. CHAPTER LXIII. VESTIGES OF THE MOSAIC DELUGE. In chapters xlvi. and l. of this book, I have referred to certain conversations I had with Sir Wm. Logan, on the existence of ocean beaches, extending from Newfoundland to the North-West Territory, at an altitude of from twelve to fifteen hundred feet above the present sea level. Also of a secondary series of beaches, seven hundred feet above Lake Ontario, at Oak Ridges, eighteen miles north of Toronto; and a third series, one hundred and eighty to two hundred feet above the Lake, which I believe also occur at many points on the opposite lake-shore. In chapter xlvi. I mentioned the fact of my finding evidences of human remains at the very base of one of these lower beaches, at Carlton, on the Weston and Davenport Roads, near Toronto.
