This evening our condition was in no way improved, except that we heard the sound and felt the presence of a strong current of northerly wind; but it blew as though issuing from a furnace, and afforded no present relief. The sky continued to show "fiery off," and the musquitoes of that ilk did credit to the genealogy my informant ascribed to them: but there is a period beyond which even suffering ceases; this happy insensibility I had attained; and when after midnight we were landed at Utica, I felt as though I could have slept soundly and well even beneath the heated deck of our canal packet. I got an excellent bed at the hotel, however; and at daylight awoke to feel once more the delightful sensation of coolness. In the night heavy rain had fallen; a light but pleasant breeze was blowing; and the past was already a subject for merriment, although it was such matter for jest as I never willingly will undertake to collect again. LITTLE FALLS. SARATOGA.--BALLSTON.--ALBANY.--MOUNTAIN-HOUSE.--CATSKILL.--HYDE PARK.--LYNN. The early hour of six A.M. saw us once more in motion for Schnectady, by way of Little Falls. We pursued what is termed the ridge road, running along the valley of the Mohawk. The day was bright, and not over-warm. The sun's rays being tempered by a delicious north-east breeze, the condition of the atmosphere completely re-invigorated the almost prostrate body, whilst the loveliness of the prospect delighted and cheered the mind. No valley in the world can present charms more varied or more beautiful; even making every allowance for the happy change from musquitoes, swamps, close confinement, and suffocation, to freedom, exercise, and healthful breezes, with the satisfaction consequent upon the re-enjoyment of all these. We frequently ran along the line of cuttings for the railroad now in progress between Utica and Schnectady. The rocky nature of the ridge whose line they pursue, offers formidable impediments; but the work was proceeding with great rapidity notwithstanding. This railway, when complete, together with the canal by whose side it runs, will afford a facility of communication between New York and Utica, which, for speed and convenience, can have no rival. We breakfasted at Little Falls, a small town built on what was, at some period or other, the very bed of a torrent, amidst the huge piles of rock riven from the mountains in its course. Although overshadowed by the steep heights that wall the ravine in which it lies, it is kept cool and healthful by the constant current of air following the rapid fall of the river, which is here precipitated over a series of rocky ledges in a wild and hurried course, giving to the ravine and town the name of Little Falls. A more picturesque, romantic site no painter could desire. I felt vexed to be compelled to leave it after about an hour's halt; and should yet more regret this, did I not hope to revisit it.
