We gladly welcome the new issue of this very useful and now famous guide. The continual changes that take place in public taste, the ever altering claims of varieties to general favor, the capital, the worthless, the useless new sorts, the results of experience in cultivation itself and many other matters most interesting to the grower, require as much vigilant attention and careful pruning as a first class rose-bush itself. We are glad to see that Mr. Rivers has used his editorial hoe to some purpose by weeding out weeds, and well stirring the ground about the sterling varieties; nor has he been less attentive to rendering his instructions so clear and precise, that even those who run may read. There is a good deal of novelty about roses in pots, and much useful information concerning stocks, the most debatable and perhaps least satisfactory question that the rose grower has to consider. That the eternal Dog Rose is a very bad stock for some kinds is undeniable, as rose buyers know to their cost.

But what is there better ? Upon this point Mr. Rivers writes as follows: -

" The Celine stock, a very old hybrid Bourbon rose, is a most excellent stock for Bourbon, Noisette (particularly the Cloth of Gold), and many other roses; if planted in a rich, moist soil, it will make shoots from four to five feet in height, fit for low standards.

"The Rosa Manetti is a rose I received some twenty years since from Como, from Signor Crivelli, who recommended it as the very best of all roses for a stock. It was raised from seed by Signor Manetti, of the Botanic Garden at Monza.

All the roses I bare budded on this stock have succeeded admirably; above all the Hybrid Perpetaals, which scarcely seem to know when to leave off growing and blooming in the autumn; indeed it is remarkable for its late growth, for it may be budded during the whole of September. Another excellent quality is, that it never gives any suckers from its roots at long distances from the plant, like the Dog Rose. It seems to flourish equally in light and dry as well as in stiff soils; and it will, I trust, be of much value to the rose amateur, who, if the soil of his rose garden be light and dry, is so often troubled with the numerous suckers thrown up by the Dog Rose. I am, indeed, now fully convinced that the only method of cultivating dwarf hybrid perpetual roses in soils that are gravelly, sandy, or resting on chalk, is to employ the Manetti Rose as a stock.

"Since the above paragraphs were written, more experience with this has been gained. Although so vigorous in growth, it does not form good standards; the stems with their side branches left on increase rapidly in bulk, but when they are budded at the height proper for standards, and the side branches cut off, the bark becomes indurated, the sap apparently ceases to circulate freely, and the stems in a year or two shrink, and the head becomes stunted in its growth and unhealthy.

" Some of the vigorous growing hybrid China roses make good half-standards on this stock, but its great eligibility is for dwarfs; these should be budded close to the ground, and, when transplanted from the nursery, should be planted so as to cover the junction of the bud with the stock, placing that part about one inch and a half or two inches below the surface of the border.

" The annexed figure will illustrate my meaning better than a host of words: a, junction of the bud with the stock; b, the height to which the stem should be covered with earth. Treated in this way the covered part of the stock increases rapidly in bulk, the sap flows freely through it, and most vigorous and healthy growth is the result. I have observed a peculiarity in this stock worthy of notice; under certain circumstances the sort budded on it will entirely overpower its suckers, so that in a year or two the plant from the bud will gain the ascendency, and the suckers, without being removed, will languish and die. This has occurred here in several instances with stocks planted out, for stocks for propagation, in a stiff clayey soil; some of these had dormant buds in them, which had not put forth their shoots with the usual crop of plants, and were thrown on one side as stocks. Now the curious part of the matter was, that immediately these stocks were planted out for stocks in a stiff soil, and so deeply that the dormant buds became slightly colored with earth, they pushed forth most vigorously; and, although the stocks at the same time put forth suckers which were suffered to grow, they have, as may be seen now in most instances, overpowered them, and now form vigorous bushes of hybrid perpetual roses, from three to six years old.

" To what a great extent in this respect it differs from the Dog Rose stock will be at once apparent to rose-loving readers; for we all know that the Dog Rose carries on a fierce war with its bud in graft, and, unless most carefully attended to, destroys it by its suckers in one season. A method of growing standard roses in dry, unfavorable soils, with the aid of the Manetti stock, may be practised by those who really love rose culture; some robust-growing, hybrid China roses - Madame Pisaroni and Duc Decazes are two vigorous growing varieties - should be budded on strong Manetti stocks below the surface of the soil, which should be removed for the purpose; from each bad one shoot should be encouraged and supported with a stake, and all others carefully removed. The second season of growth the stems thus formed may be budded with hybrid perpetual roses and others; they soon form nice healthy stems".
