"For want of a better, we use this term to designate all those Roses that bloom only once in the season, and that strongly resemble each other in habit and flower. It includes those classes called, by rose-growers, French, Provence, Hybrid Provence, Hybrid China, Hybrid Bourbon, White and Damask Roses." We refer our readers to Mr. Parsons' work, for many interesting particulars in relation to this classification, and for a select list of Roses, coming under this head. During the season of the flowering of the Rose, we noted a few varieties as being very fine, among which were the following : White Roses. - White Unique, Madame Hardy, Madame Plantier, Ball of Snow, and Princess Clementine. The old-fashioned White Rose should not certainly be forgotten, as it is associated with childhood. It is one of the three first Roses that opened their buds to the writer. Who can forget the old White Rose, as it was trained up the side of the house ? We have seen a rose-bush, of this variety, trained fifteen feet high.

White Roes, Striped, Mottled, or Shaded. - Painted Damask, Margin Globe, Modeste, New Village Maid, Old Village Maid.

Rose-colored. - Franklin Provence, Las Casas, Caroline Mignonne, Triomphe of Breslau, Perpetual de Angers.

Deep-red. - Velours Episcopal, Cerise Superb, Fulgens, 29th of July, Brennus, La Fontaine, etc.

Purple and Dark Roses. - Mirabella, Gen. Thiers, Gen. Lamarque, Bell Thurette, Madame Camper, etc.

This list might be extended, but I have given enough, proba-oly, to select from.

Moss Roses. - This is a well-known and elegant class of

Roses, of which the common Moss is about the only one that is very familiar. The Luxembourg Moss has dark crimson-cupped flowers, and is a vigorous grower. Perpetual White Moss is handsome only in bud. It produces a large cluster of beautiful mossy buds, but the flowers are inferior. It is not properly a perpetual, but produces a long succession of buds. The White Bath Moss has fine white flowers, which are sometimes lightly striped with pink.

Princess Adelaide is one of the most vigorous-growing Moss Roses, and would be one of the varieties we should recommend.

Cristata, or crested, is a singular and beautiful variety. Excepting when in bud, it does not have the appearance of a Moss Rose. The calyx has a beautiful crested appearance. "In a rich soil, this fringe-like crest most beautifully clasps and surmounts the bud, and gives the rich clusters a truly elegant appearance. Its form is globular, and its color rose." Other varieties recommended are, Alice Leroy, Crimson, Catharine de Wurtemburg, Celina, Eclatante, Lancel, Prolific, Unique de Provence, and Zoe.

Scotch Roses. - This class of Roses are distinguished by their small leaves, prickly stems, abundant bloom, delicate habits, early bloom. They flower about two weeks before the summer Roses. They are suitable for growing in masses, or borders, and the shrubbery. The original, from which all the varieties sprang, was found growing wild in Scotland and the north of England. In some of the catalogues two or three hundred varieties are described, but many of them are so near alike, it would be difficult to see the difference. Mr. Parsons says there are scarcely forty or fifty, distinct; and of these he recommends, as the three best, the Countess of Glasgow, Queen of May, and William the Fourth.

Brier Roses. - "These Roses are distinguished by their small, rough foliage, and brier habit. They include the Sweet Brier, the Hybrid Sweet Brier, and the Austrian Brier."

The Sweet Brier is a native of Europe, and found abun dantly in some parts of this country. Mr. Emerson supposes that it was introduced into this country, and now has become naturalized; the seeds having probably been disseminated by birds.

The Double Yellow Provence Rose is supposed to have had its origin from the Austrian Brier. It is an old inhabitant of some gardens, but a very shy bloomer, showing its flowers very sparing, and, some years, none. We have seen the bushes bending with their load of flowers. They are large, very double, of a pale-yellow. On account of its peculiar habits, it is not worth its room in the garden. Copper Austrian "is a very singular-looking Rose, blooming well in this climate, is of a coppery-red, and the outside inclining to pale-yellow, or sulphur." It has single flowers, but they are truly beautiful. The Yellow Harrison Rose v\as considered a great acquisition, a few years since, but this is now entirely eclipsed by the Persian Yellow. Its flowers are more double, and of a more brilliant yellow, than the Harrison; and this is the only hardy yellow Rose we know of, really worth growing, except the Copper Austrian. The flowers of the Austrian Roses are produced on short joints all along the stem; they will not, therefore, bear much pruning.

The common Sweet Brier is worthy a place in every garden, on account of its exquisite fragrance. In pruning this section of the class, the old wood only should be cut out.

"Double-margined Hip is a Hybrid Sweet Brier, of luxuriant growth, almost adapted to a pillar. Its form is cupped, and its color creamy-white, shaded.with pink."

Climbing Roses. - The Climbing Roses may be divided into four or five sub-classes, viz., Boursalt, Ayrshire, Prairie, Hybrid China, Noisette or Bourbon, and Miscellaneous. In the Miscellaneous class, the old-fashioned Cinnamon may be placed, not knowing where else to put it; and it should most assuredly have a place somewhere, "for auld lang syne," nothing more. It deserves a place in the shrubbery, on account of its early flowering and profuse bloom. It opens its rose. 289 blossoms the last of May, in this climate, and, with a little attention, will make a bush ten or twelve feet high.

Boursalt Roses. - The Boursalt Roses come next in bloom after the Cinnamon. They are all desirable on account of their hardy character and vigorous growth. "Their smooth bark renders them desirable for stocks to bud upon." For the extreme north, this whole class, next to the Prairie, are the most desirable for pillars and trellises.
