To be precise and in order: Professor Johnston arrived at Halifax on the 7th day of August, 1849. On the 4th of September he took the steamboat at St. John, and arrived the following morning, at Portland, in the state of Maine, in time for the railway to Boston, where he arrived at 2 P. M., and after two full hours of keen observation, (a largo share of it at the dinner table,) in that promising little town, again took the cars for New-Haven, where he arrived at 11 o'clock the same night.

"In this rapid run through New-England, only three things made a permanent impression on my mind. These were, first, that the general rudeness of the people which travelers speak of [what travelers? we would humbly inquire,] is not perceptible in New-England generally. It may be more strikiag in the western states." But after all, our Professor doubts that even in Old England, if all classes of travelers were indiscriminately mixed up by fifties and sixties together in a train of cars, the passengers might not behave so well as those of New-England do. A precious, although a grudging confession, truly. "The second thing was the numerous country boxes or cottages, of all fashions and sizes, with their white painted walls and green jalousies, which skirted the railway during the last veled author suppose that the untutored Yankees dwelt in wigwams outside the cities, and lived by hunting, instead of growing farm crops, garden fruits, and vegetables? . "And my third observation was, that though the drouth of Nova Scotia and New-Brunswick had extended into Maine, its effects became less perceptible as I advanced westward into the other New-England states, till, in Connecticut, the fields looked as beautifully green as I had seen them last at the mouth of the Mersey." It must have been a "permanent impression" truly, that in a range of four hundred miles, from the fog-ridden banks of Nova Scotia, and through a declining latitude of five degrees, he should have discovered that New-Haven weather had been quite as irreverent in its imitation of a "drouth" in the provinces, as its people are regardless of some of the practices of their provincial "kindred."

Spending four days in New-Haven, which gives him material for some eight pages of comment on what he saw in and around the city, and Connecticut in general, he started on the 10th for Syracuse in company with Professor Norton. On his way uptheHousa-tonic valley to Albany, whirling along in a rapid railroad train, he remarks on the "drift" and geological formation of the country, which he obtained, of course, from his intelligent informant and traveling companion. At Albany a stay of one night is made, and in the next half day's ride up the Mohawk, his geological observations continue, coupled with a dash of agricultural remark, and a running commentary now and then, neither new nor profound, on soils, climate, and crops. By way of variety, also, are interspersed the stereotyped remarks of foreigners upon the odd names of our towns and villages, and some equally original reflections upon our manner of elections, fondness of titled names, and popped corn, in particular. Rather annoyed at the accession of Mr. Clay, to the traveling train at Utica, our author proceeds in his commentaries through Rome, not "the Niobe of nations," but little Rome, on the Mohawk, then full of enthusiastic curiosity for a sight at the great statesman; then to Verona, where no "two gentlemen" bid him "good morrow;" thence to Syracuse, where he arrives "at half-past three, distance 178 miles from Albany."

As Syracuse - to which place he had been invited by the State Agricultural Society, to deliver the usual address made before the multitude assembled to attend its annual jubilee - is to be a point in his travels and observations, a full chapter of thirty-three pages is devoted to the discussion of sundry matters and things appertaining thereto, and the country by which it is surrounded. As it was the theatre of his own personal display, too, for the time, we shall follow him somewhat closely for the two and a-half days - we like to be precise in some things - that he remained. With a like originality of remarks as before, he finds that Syracuse is "a new city of 16000 inhabitants, large hotels, numerous churches, and skeleton streets, which, if its prosperity continue, will soon be built up," - "so late as six years ago, the wilderness still surrounded the residence of the m: yor - to whose hospitality I was indebted during my stay at Syracuse - where his garden now extends, and plum and peach trees and vines are in full and luxurian' bearing."

Our author's notes are accurate, no doubt; but we would give a trifle to learn the wonderful method of transforming a wilderness "into the sites of noble mansions and dwellings, with highly ornamental gardens, towering shade trees, and paved streets, which extend far beyond the fine premises of Mr. Leavenworth, within the brief period of six years, and meekly inquire whether, if the word, twenty, were prefixed to the "six," it would not be nearer the ark? Such is our own recd ection.

Professor Johnston goes with his attentive friend, Mr. Norton, into the show yard. Things here are, very naturally, compared with the show of the English Royal Agricultural Society, and as they agree with that, is the exhibition more or less deserving. Some things he commends, other things furnish him a text for commentary, and as the people, in a country where the best of unimproved lands can be had for fifteen to twenty dollars an acre, have not as yet under-drained all their swamps, at an expense of twenty to thirty dollars the acre, he has made up his mind (another original idea) that as "yet in New-England and New-York, there is no such thing as local attachment - the love of a place because it is a man's own - generally speaking every farm, from Eastport in Maine, to Buffalo on Lake Erie, is for sale!" Accommodating people, most truly! Thence follows a homily on the superior production of land where the owner of the soil and its cultivator, hold the relative attitudes of landlord and tenant, upon which his remarks are quite as profound as a stickler for the cast-off feudal usages of Europe may be supposed, winding up by an equivocal compliment to "our respected Yankee cousins."
