I must apologise for this seeming digression. However, as I have not entirely abandoned my photographic impressions, I take it for granted that I have not presumed too much on the good nature of my readers, and will now endeavour to further develop and redevelop the Hudson, and point out the many phases of beauty that are fit subjects for the camera which may be seen on the waters and highland boundaries of that beautiful river in all seasons of the year. Albany is the capital of the State. It is a large and flourishing city, and one of the oldest, being an early Dutch settlement, which is sufficiently attested by the prevalence of such cognomens as "Vanderdonck" and "Onderdunk" over the doors of the traders. About six or eight miles above Albany the Hudson ceases to be navigable for steamers and sailing craft, and the influence of the tide becomes imperceptible. Troy is on the east bank of the river; and about two miles above, the Mohawk River joins the Hudson, coming down from the Western part of the State of New York. For about two hundred miles the Hudson runs almost due north and south from a little below Fort Edward; but, from the Adirondack Mountains, where it takes its spring, it comes down in a north-westerly direction by rushing rapids, cascades, and falls innumerable for about two hundred miles more through some of the wildest country that can possibly be imagined. We did not proceed up the Upper Hudson, but I was told it would well repay a trip with the camera, as some of the wildest and most picturesque scenery would be found in tracking the Hudson to its source among the Adirondack Mountains. I afterwards sailed up and down the navigable part of the Hudson many times and at all periods of the year, except when it was ice-bound, by daylight and by moonlight, and a more beautiful moonlight sail cannot possibly be conceived. To be sailing up under the shadow of the Palisades on a bright moonlight night, and see the eastern shore and bays bathed in the magnesium-like light of a bright western moon, is in itself enough to inspire the most ordinary mind with a love of all that is beautiful and poetical in nature. Moonlight excursions are frequently made from New York to various points on the Hudson, and Sleepy Hollow is one of the most favourite trips. I have been in that neighbourhood, but never saw the "headless horseman" that was said to haunt the place; but that may be accounted for by the circumstance of some superior officer having recently commanded the trooper without a head to do duty in Texas.
