Agriculture - of which every idea that he has, as applied to the region of which he discourses, is given by some previously introduced acquaintance, or fellow passenger in the cars - receives a part of his attention; and politics, forms of government, existing institutions, and miscellaneous matters, follow, as drawn from, but not credited to, the books and statistical tables of which he is possessed.

Hailing from Buffalo, where our traveler spent an entire night, he dashes, in imagination, away to the far west, and by aid of the aforesaid statistical tables and maps, and geographies, and Lyell's, and other's American Geology, talks of Wisconsin, and the country about Lake Superior, the "Hog crop," and "Cattle crop" of Ohio, and settles down with a surprisingly "clever" act of "a gentleman introduced to him at Syracuse, but whose name he did not know," who invited him to spend the night at his house, two miles out of the city, which he declined, owing to the brief stay he should make, but who, nevertheless, furnished him unsolicited, with free lodgings at the "American Hotel." This is noted "as an instance of the proneness of our trans-atlantic cousins to the virtue of hospitality," as also the truth of his own reiterated remark, that "blood is thicker than water."

Stepping in, while at Buffalo, at a butcher's, after asking him sundry questions, which were duly answered, and then answering the butcher's questions in turn, he writes. - "Well, sir, says he, (the butcher,) we live in a great country here - we are a great people." Now we dare risk our veracity against that of Professor Johnston, that the aforesaid butcher never said any such thing; or, if he did say so, that he was a foreigner of British birth. "It is unpleasant to a stranger to be always called upon to admire and praise what he sees in a foreign country; and it is a part of the perversity of human nature to withhold, upon earnest request, what, if unasked, would be freely and spontaneously given." Then a fling at the "brag and swagger among individuals in the United States." An amiabh man, too, is Professor Johnston.

Leaving Buffalo on the morning of the 16th, for the Falls of Niagara, he tarried a full twenty-four hours at the latter place. He viewed the falls from both sides of the river, and treats us to a few trite remarks of moderate admiration, and a borrowed cut of the geological formation of the rocks at that point. He then hurries off to Lewiston, on the 17th, and takes the boat, where "we steamed through the mouth of the Niagara river." We really wish, for the reputation of all concerned, that our Professor had informed us whether it was himself and his companions who did so much steaming. - whether it was simply the tea-kettle steaming up the water for their whiskey-toddy, or, only the innocent boat itself, driving her paddle-wheels by aid of steam through the water - for this word "steaming" has sometimes an equivocal meaning on both shores of Lake Ontario, among "our trans-atlantic cousins."

On board the boat on the way to Oswego, another conversation was had "with a practical farmer from Syracuse." The result of this conversation was, a drawn conclusion as to the profits and hopes of farming as a business. Yet he was impressed with the opinion that the New York farmers knew much more of the geological formation of their own soils, than the English farmers did of theirs. From six to half past ten o'clock in the morning, our author waited at Oswego, where he found that "the flouring mills were the chief source of the prosperity of the town."The extensive commerce with the upper lakes and with Canada, which that thriving town enjoys, he did not hear of. Thence to Sackett's Harbor, which "shows nothing to attract attention, beyond its hotel, and some signs of increase in size."From Sackett's Harbor "we steamed" again through the Thousand Islands, to Kingston, Upper Canada, and "at 6 P. M. we landed on the pier." "I almost felt myself at home again, as I set my foot on shore in sight of longer time than he spent in the whole region of the United States from New-Haven to Niagara, in which prolific tour he drew the material for half a volume of speculation and theory, on matters and things in general.

We here leave the author for several months, to talk to his countrymen at home, as he may, of the advantages of "the Provinces" over the United States, regretting only, as we close this part of his travels, that his good taste could not have dictated a better story than the shabby slur upon the housekeeping virtues of our Yankee women, which he has chronicled: "I'll go over to Canada for a wife when I marry," said a young South Shore farmer to his friend. "When I come home at night she'll have a nice blazing fire on, and a clean kitchen, and a comfortable supper for for me; but if I marry a New-Yorker, it '11 be, when I come home, 'John", go down to the well for some water, to make some tea,' or 'John, go and bring some logs to put on the fire, to boil the kettle.' No, no; a Canadian woman 's the wife for me." Vol. 1, p. 263. His "South Shore" hero probably wanted a drudge, instead of a companion.

On the 24th of the following December, our author again finds himself, amid the discomforts of winter travel, entering the north-east point of Maine, in a journey from St. John to Boston and Albany, at which latter place he was engaged to deliver a course of lectures on "the general relations of Science to Agriculture," before the members of the Legislature, and the New York State Agricultural Society. On the 28th he is again domiciled at the hospitable quarters of his young friend, Professor Norton, in New-Haven. Here he makes a stay of several days; and although he observes a studied silence regarding it, we have no doubt he was introduced by Mr. Norton to several of the learned and accomplished faculty of Yale College, had free access to the extensive and richly stored cabinets of Professor Silliman, and that all the geological, mincralogical and chemical treasures of that highly reputable University were opened to him; but whether he felt bound by considerations of delicacy to say nothing of either, or all of them, or whether he found himself, on comparison with men of real attainments, altogether out of position, is no business of ours; yet, as a characteristic acknowledgment of the kind attentions and hospitality he must have received at New-Haven, he sneakingly records a dirty slander of Fenimore Cooper, an American author, on the meanness of Connecticut hospitality! And it is with such creeping inuendoes at his heels, that we have followed him thus far on his journey in the United States. At so fitting an opportunity we cannot forego the relation of a private anecdote, slightly touching the good manners of this Agricultural Professor: During his stay at one of our cities, where he gave lectures, he was invited by a gentleman residing some miles out of town, to dine with a party, among which were several gentlemen of distinction, and an ex-president of the United States. A highly respectable Scotch gentleman, resident in the neighborhood, was of the party, and presuming that both he, and Mr. Johnston, would be mutually pleased at meeting, as fellow countrymen, their host introduced them to what "he hoped," as he led them together, "would be an intimate acquaintance." But our Professor, after slightly noticing his countryman, abruptly turned away, and continued a conversation with his host.
