Very shallow planting is urged by Mr. Bright, as of great importance in grape-culture, as well as in all other branches of horticulture. While we do not believe in very deep planting, we also look upon very shallow planting as a thing to be avoided in grape-culture as an evil, the consequences of which are more disastrous than that of very deep planting.

The advocates of shallow, or surface planting, as we must call it, say that, if the roots of the vine are allowed to penetrate the cold, wet subsoil, that it will languish, and the roots will decay, the vine become sickly, etc In the first place, vines should never be planted upon soil that has a cold, wet subsoil, for in such cases they will fail, whether planted on the surface,, and soil heaped over them, or a foot below. If soil is properly prepared, say at least two feet deep, there will be found to be little danger of the roots remaining too deep in the soil, even if they were placed there at first; for it is well known to every one who has examined a grape-root, that the great tendency of the working roots is to the surface, and if they are allowed to take this position, and hold it, the lower roots having nothing to do, soon decay.

Now these surface roots are exposed to every change of weather; if it is dry, they feel it first; if a warm shower comes, and 60on after great heat, the tender rootlets are exposed to such a degree of heat that they are scalded, the effect of which is soon seen by the shrinking of the fruit and drooping of the leaves. In cool climates this will not often take place; but then, again, the roots, when very near the surface, are exposed to the cold, which often destroys them.

Keeping the working roots of the vine several-inches below the surface, was considered in olden times a thing that must be accomplished; and to effect this, end, the operation of ablaqueating the vines was resorted to, which we find described in all the ancient works on agriculture. To be sure, they had a somewhat warmer and drier climate than we have; and, again, they never thought of planting vines on ground that had not been thoroughly paginated (pulverized) to the depth of from two to four feet This operation of ablaqueation was the removing of the surface soil around the stock every autumn, and cutting off all the surface roots close to the main stem, to the depth of six to eighteen inches; some writers recommending more, and others less - differing according to locality, soil, etc. - but all speak of its importance.

In this latitude no working root of the vine should be allowed to come within six inches of the surface, and at the south a still greater depth will be required for perfect security against the changes of the climate. Our best and most experienced vine-growers at the present day understand the importance of having a dry,porous soil, and then compel the vine roots to work below, instead of on the surface.

We asked Mr. Schneike, of Cincinnati, (who is certainly authority on this question,) what was his object in trenching his ground three feet deep, and putting the surface soil at least two feet below the surface. His answer was, that he wanted the food for his vines below the surface, because he wanted the roots to work there, and not on the surface. Mulching is recommended by Mr. Bright, as a protection for the roots in surface planting. This will answer very well for vines or other plants the first season; but to continue it for an indefinite period, and have it successful, is very doubtful, besides being very troublesome. It is making a safe harbor for all kinds of vermin; and further, the most that can be said of it is, that it is the most slovenly mode of cultivation in appearance that can be recommended.

Mr. Bright claims you, Mr. Editor, as well as Marshall P. Wilder and P. Barry, as favoring this system of surface planting; but if either you or they have ever practised or commended the system, we have failed to discover it.
