Among garden bulbs, the Gladiolus is perhaps one of the most popular, or at least is in a fair way of becoming so. The introduction of Gandavensis, a few years since, gave a new impetus to their cultivation, and in the hands of the French they have been made to take their place among the gayest flowers of the garden. Not their least recommendation is the easy manner in which they may be grown, any common garden soil suiting them well; though, in common with all other plants, they make a grateful return for any labor bestowed upon them. A very rich soil is not the best for them, as it is apt to make their colors run. Old manure from a hot-bed, with some vegetable mould, thoroughly incorporated with the soil, is about as good as any thing that can be used; the manure, however, should be used sparingly. They may be planted singly, or two or three together, and provided with a stake. The crown or top of the bulb should be about two inches beneath the surface. In the fall the bulbs are to be taken up, and stored in a green-house or cellar, free from frost.

But we only design to give a list We examined last season upwards of a hundred varieties at Mr. Bridge-man's, at Astoria; and, in order to help our readers to make a good selection of those already known, we append a list of twenty-four which we marked best. Some of the new kinds, of which we have just received a fine collection from Messrs. Thorburn, may prove to be even better than those named; there are others also nearly or quite as good as those in our list, and these should not be forgotten. The improvement is still going on, and the best we now have may soon be surpassed. The following, however, can not fail to give satisfaction.
