A walled city will long, we trust, be a novelty to our people; but it is a curiosity, and this sight alone would repay a visit. Historical interest of no common kind attaches to it, but our business is with its surroundings, which space compels us to make brief account of.

John Gilmore, Esq., has a large and beautiful spot at Wolfe's Cove, so named because it is the scene of Wolfe's landing. Evidences of its former history are displayed in a pile of large cannon balls in front of the piazza, taken from the battle-field. The Plains of Abraham are between the mansion and Quebec, and beneath a fine bluff flows the majestic St. Lawrence, with busy men loading numerous huge ships with lumber and produce, for distant European markets. Mr. Gilmore has everything about him in the best and most liberal condition. His stables are models of extent and comfort. The garden, large and well filled, displays a variety of elegant flowers, fruit and vegetables. As much as thirty bushels of gooseberries have been picked from his bushes in one season. They certainly are remarkably fine. Potatoes are produced here of a superior quality, free from the rot. The planting is excellent. For evergreens, there are the black and white spruce, of great age and beauty. Take the views, the cultivation, and the the extent of improvement, with the refinement within doors, and add the kindness and suavity of the host and hostess, and every one who visits Wolfe's Cove must come away delighted.

James Gibb, Esq., at Woodfield, possesses one of the most charming places on the American Continent. ' Thoroughly English in its appurtenances and laying out, its views of the St. Lawrence, its lawns, trees, and superb garden are together a model of what may be accomplished. The whole scene was enchanting. The traveller felt as if he was transported to the best parts of old England, and our whole party united in an exclamation of pleasure and gratification. Here is everything in the way of well-kept lawns, graperies and green-houses, out-buildings for every possible contingency of weather; gardens, redolent of the finest flowers, in which bulbs of the best lilies make a conspicuous figure, and every species of fruit that can be grown. Mr. Gibb is a self-made man, is now President of the Quebec Bank, and a very useful citizen. The traveller who does not see Woodfield has not seen Canada in its best trim.

Thomas Gibb, Esq., at Bellevue, occupies the place originally laid out by his brother James, and is in possession of a house with few compeers. His garden is well taken care of, and eminently beautiful and successful, as are his graperies and green-houses, no less than his peach, nectarine and apricot house. In describing the place, our kind cicerone might well say, "There is everything at Bellevue except dirt? The front view from the house is obstructed by shrubbery and trees, which if removed would add greatly to the effects. Where lumber is so cheap as at Quebec, one need not wonder, at the amount of outbuildings we find at all the first-class places. They furnish sheltered occupation for the long winter months. The best melons, conspicuous among which is the great Lisbon, and grapes were ripening under glass, the quantity of which is quite astonishing. The drive of a mile or more into the grounds here, is through one of the best avenues in America. It is planted with the native evergreens, white birch, mountain ash, and other good trees; and the road being of excellent shale, it compares favorably with a noble drive in Europe. We must not omit Mr. Gibb's large collection of the choicest standard roses; these are very superb and well-trained. Many of the newer and rarer plants, described lately, are found here.

The St. Foy and Carouge Roads reveal a succession of excellent mansions, with well-kept grounds. We can only name those of William Atkinson, Henry Burstall, and William Price, Esqs. Suburban residences of great beauty are met with at every turn. New roads, and streets, and houses are everywhere in progress, and attention is specially given to the garden.

The vicinity of Quebec, on both sides of the river, is well-settled. As you ascend towards Montreal, the country and climate both improve - the summer is a month longer. The first frost is expected at Quebec by the 10th of September, and they are consequently cut off from growing many things that at Montreal are successful; nevertheless, there is much to enjoy. Apples in some situations are abundant.

The Falls of Montmorency are easily reached by a carriage drive, during which an excellent opportunity is presented of seeing the French habi-tans, and their peculiar houses and mode of life, but these must not detain us. We will, however, look in upon Dr. James Douglass, adjoining the Lower Canada Lunatic Asylum, of which he is the founder and co-proprietor. Dr. "Douglass is emphatically a man of taste, and of that universality of admiration for the beautiful which makes a country home like his a perfect thing. Evergreens of great beauty and considerable age, make the first impression; next, a mansion eminently well-furnished with all that Europe can sell, including books, statuary, mosaics, etc, is ensconsed between a first-class conservatory, with the plants in the ground, on one side, and a noble grapery on the other. The view from the drawing-room, through two plate-glass doors, struck us as the finest thing of its kind. The rarest plants in full perfection, the best runners mounting the roofs, and fuchsias, twenty feet high, in perfection, gave an air to the place beyond describing. Altogether Dr. Douglass deserves the highest award of admiration for what he has accomplished, in our power to bestow.

Note. - In all such establishments, one may be allowed the expression of satisfaction always to see the Horticulturist a valued drawing-room guest.

The Lunatic Asylum contains nearly five hundred patients; so well conducted is it, that it is patronized by the State to the number of about two hundred. Everything that alleviates misfortune is here applied; modern science and practice are so thoroughly combined, that not a single patient was under restraint. The place is as clean and neat as any hospital in the world.

Up to this point, and still further into New Hampshire, every public table has been supplied with abundance of the small wild strawberry. It is good, but not equal to the cultivated kind, which in time will be more plentiful. The ample native supply seems to discourage cultivators from attempting the sale of improved varieties, but they must and will introduce such as the Albany seedling. Mr. William Brown at Montreal is successful with the improved varieties.

It would be unjust not to record the very kind attentions of Edward Glackmeyer, Esq., himself a good horticulturist, and the esteemed President of the Association of Lawyers, who gave us his time unstinted to the examination of Quebec and its neighborhood.
