THE following pages duly explain themselves, I judge, as to the Author's point of view and his relation to his subject; but I prefix this word on the chance of any suspected or perceived failure of such references. My visit to America had been the first possible to me for nearly a quarter of a century, and I had before my last previous one, brief and distant to memory, spent other years in continuous absence; so that I was to return with much of the freshness of eye, outward and inward, which, with the further contribution of a state of desire, is commonly held a precious agent of perception. I felt no doubt, I confess, of my great advantage on that score; since if I had had time to become almost as -fresh- as an inquiring stranger, I had not on the other hand had enough to cease to be, or at least to feel, as acute as an initiated native.
