In looking over Mr. Prince's new catalogue, he says: "The above Magnolia conspicuasare grown from seed, seven years old, well branched, very vigorous, and perfectly hardy, and are splendid specimens* They are the only ones of this character ever offered for sale - all others being grafted and weakly"

As an offset to grafted or budded trees being weakly, I send you an account of my tree, which is six years growth from the bud. It measures over sixteen feet high from the ground; width of branches, eleven feet in diameter, which commence at twenty inches from the ground, and it has on now (May 4th) nine hundred and eighty perfect blossoms and is a beautiful sight. If Mr. Prince, or any other person, can show as large and perfect a specimen grown from seed in six years, or even twelve, I hope they will give some notice of it My experience is, that Magnolia conspicua and Solangeana grow twice as fast budded on M. acuminata stock as they do from seed. and nurserymen would find it to their advantage to propagate them in this manner. These Chinese Magnolias are yet scarce and in demand, and will find ready sale at good prices far many years to come. Char. Downing. - Newburgh N. Y

Magnolia Conspicua #1

The finest blooming specimens of this glorious tree are grafted on the acuminate; this gives them a compact habit, and with abundance of flowers. The last spring was particularly favorable to the blooming of the Conspicua; the cold retarded it, and a profusion of flowers were entirely uninjured. St Patricks day in this neighborhood usually produces flowers, and between the Saint and his wife and the snow and blow that are all but universal, we have this favorite often terribly knocked about, but if it bloomed but once in five years, we should consider it indespensable.

A correspondent who has a deep glen near his mansion inquiries how he shall best fill the deepest parts so as to present to the eye an evergreen appearance in looking down upon it Inequality of ground is often one of its greatest beauties, and care must be used not to obliterate it entirely. Trees grow taller in the valleys than on the hills and will therefore not answer. A green, grassy appearance may be effectually produced in a deep ravine by planting it with American Arbor vitae, placing larger plants in the deepest parts, and the smaller on the sides; occasional shearing off the tops to keep them nearly on a level, will produce the desired effect; the plants brought from Maine may with care, and a year or two preparation in nursery rows, be procured at very moderate cost, and they will prove not only cheap but better than any other description. Planted young with nothing to interfere with its side shoots, the American Arbor vitae forms a charming screen or hedge in a few years, of eighteen feet in height A slight objection to this plant is that it becomes brown in winter, but its spring and summer aspect is highly gratifying. It will be well not to neglect our native productions for semi-hardy evergreens which have given little satisfaction during the late hard winter.

Where the valley is large and deep, the Norway Spruce may be substituted; this tree, the gardeners say is on the whole the most generally satisfactory evergreen to the purchaser that they sell. The next that comes into full fashion we hope may be the Hemlock, respecting, the treatment of which we shall hereafter allude.

Will you please to inform me if Paeonies will come up the first season planted in May, or when is the right time to plant, or if they require to be frozen before they will germinate, and give me a few items about cultivating them. Please to give me imformation through the Journal, Richard Speid. - Centreville Iowa, May 20th 1855.

The seeds should be sowed as soon as ripe, and after one season's growth in the seed bed may be transplanted into place for flowering. They are easily managed.
