If the regulations regarding passports that are enforced in Italy, were adopted in America, probably fewer persons would be found behind our locomotives. In the town of Bologna, at this moment, says the last Quarterly Review, no man can have a passport to leave his home, unless his wife, in person, or by letter, signifies her permission that he should go; if he is single, an attestation from his curate of "stato libero" is required. A gentleman cannot visit his property, and a domestic cannot go to see his family, a few miles distant, without a passport, to obtain which, in proper form, requires attendance at different places. Nor can any servant be dismissed without informing the police whither he is gone, and whence his successor comes.

What a contrast our country exhibits. The passport system is not much better in other European countries, while here we follow every whim, and trot about with as little consideration as if there was nothing to do at home; home, in fact, there is none to a large portion of our population. But, if we are ready to question what objects are taking the numbers travelling on steamboat and railroad, whom one meets in every direction, let us remember they have the same right, if right there is, of inquiry regarding ourselves. So we had better proceed to business.

Mr. Sargent's kindness arranged excursions for our horticultural party, by rail-road, to the successfully planted places up and down the river: these were per-formed with comfort and ease, in consequence of the regularity and rapidity with which the managers of the road contrive to run their cars. The first was to the grand establishment of Rockwood, the seat of Edwin Bartlett, Esq., near Tarrytown, about thirty miles above the city of New York. We found Mr. Bartlett in possession of a princely mansion, having a facade of nearly one hundred and fifty feet, several hundred acres of land finely situated on the banks of the Hudson, with a beautiful reach of river view, and with sufficient native trees on the front to screen it from obtrusive observation. The planting round the house is new; there are, however, a few of the original shade trees left, to break the glare of the southern front. Mr. Bartlett has just arranged for extensive conservatories and greenhouses, under the management of Mr. Leucare, a builder of these structures of great experience. His other improvements employed, at the time of our visit, about eighty men.

There can be little doubt that, with Mr. B.'s means and liberal expenditure, and the great interest and taste shown by both Mrs. Bartlett and himself, Rocbwood will become one of the most ornate and. beautiful country-seats in America.

At Mr. Bartlett's, we had a discussion on the merits of the lawn mower, highly favorable by comparison to- that instrument, and we are confident that, when it is introduced on these extensive lawns, their appearance will be greatly improved. A good lawn is so much the foundation of beauty in a country residence, that there can be no perfection without it. The dream of Downing regarding the perfection of our country-seats, will never be realized until, by deep trenching, we provide for the sustenance of the roots of the grass in our long summers, and, by this or some other mower, we shall be able quickly to remove the growth, and roll the surface. We are rapidly coming at this point., and by no means so rapidly as through the use of Swift's lawn mower. A single inspection of a highly kept place, will convince the most sceptical that no other expenditure is so important as the careful keeping of the grass. And yet, strange to say, there is no expenditure that country gentlemen hesitate more about than the frequent cutting of their lawns.

There is many a place we know of, where one to two hundred thousand dollars have been spent, and yet, where the owner hesitates about cutting his lawn once in ten days, on account of the expense, and refuses to keep the grass short in the park by feeding, because he can't afford to lose his hay; and yet this same gentleman will sigh over the beauty and keeping of English places, when, if he would do as the English do, his own place, would be every whit as fine. Where do you see, in England, a park in hay? *
