We have lately been shown some sheets of a new work under this title, by Dr. C. W. Grant. A more expressive title, perhaps, would have been Pomological Landmarks, as the work will be devoted to pomology. The sheets that we have seen are devoted to the Strawberry, and the subject is treated in a manner that is highly interesting. There is a degree of freshness in the style and manner that has been adopted that makes very pleasant reading. The Doctor's own experience is given somewhat in the style of a diary, the dates forming landmarks of historical value. As an example of the style and manner of treating the subject, we give an extract, from which the reader can gather an idea of the Doctor's preferences and mode of culture at the end of twenty years' experience :

"I should, perhaps, state at the conclusion of my twenty years' experience what kinds and how many I now cultivate for my own use, so that, all things consider. ed, I may have the largest measure of enjoyment from strawberries for the longest time, early and late.

"I cultivate only Bartlett and Triomphe de Gand. If Buist's Prize, Long-worth's Prolific, Boston Pine, Fillmore, Downer, Vicomtesse Hericarte de Theury, and Constante were added, I should get no addition in the way of variety, and perhaps much difficulty in keeping separate beds; and, in making them ready for use, constant care and trouble will be required to keep them separate.

"But, supposing this all done, nothing desirable is gained. The first two (Buist's and Longworth's) are to every palate far from giving as much enjoyment in flavor as those named; and of the whole number, Boston Pine is the only one that can come into competition with the Bartlett; but it has no superiority over it in any respect, and is not nearly so tolerant of negligent treatment. The others may all be brought into comparison with Triomphe de Gand, and offer no distinct sensation in the way of flavor, and no advantage in any one point. Two of them may be found to be equals - Vicomtesse and Constante.

"I am in expectation of admitting one more, that promises to continue the season later than Triomphe de Gand, with fruit of largest size, having the wild strawberry flavor in full, and borne very high from the ground. It must sustain one season more of trial, when, if its promises of three past seasons are fulfilled, it may be admitted for having a distinct delight in flavor and high merit in all respects. Some would admit Burr's New Pine, but with those who have cultivated it, and myself included, it has gone into disuse.

"When grown by the curious amateur, the number may, with interest for a time be indefinitely extended. They are all beautiful and interesting to make up the variety for an occasional party, but not those that one would choose to make every day life with; and when the interest that for a moment only attaches to variety has passed, the only difference which they will be found to have from one or the other of our duo will be very nearly measured by their degrees of inferiority. I would remark, in reference to the Bartlett, that for the year past I have entertained some suspicion that it may be a Boston Pine so changed by circumstances as not to be recognized by the best judges who are most conversant with both. Its characteristic differences are, much darker color, less firmness of flesh, more abundant foliage, bearing more abundantly than any other variety under negligent treatment, which is the reverse of the Boston Pine. In carrying its fruit high above the ground, Boston Pine is in some degree superior to the Bartlett, bat the latter carries its fruit always well up from the ground on strong, woody scapes.

"1 have grown strawberries in every variety of soil, from heavy clay to light gravel and pretty open sand, including a reclaimed alder swamp, and have found but little difference, so far us crop is concerned, but the difference in cost of prep aration is very great In every garden that is fit to be called such, the conditions of a strawberry bed are always present. This is not inteuded to say that all good, rich garden soil is fit at once for the reception of strawberries, but the contrary; for soil that has been well cultivated for a series of years, although it may be rich and deeply worked, is not to be planted with strawberries without amendment, and the compost which I have named, or sods, or muck, including leaf mould, with some stable manure, are the suitable materials for this purpose. Without this, failure will be likely to occur. In fitting the ground for the best results in the one, it is fitted for the other, and a well-prepared strawberry field, after ceasing to use it for that, has undergone the best possible preparation for any kind of fruit, be it trees or vines, provided the ground has been worked to sufficient depth.

But much less depth will give very satisfactory results with strawberries than would be thought permissible for a more permanent planting, as for a vineyard or orchard of standard pears. Under favorable circumstances, eighteen or twenty inches of depth will answer very well for strawberries; but no one who aims at good success and permanence with standard pears, will plant on ground that has been worked less than three feet. Still, the strawberry culture has been one great step in the preparation; and when the vines are dug under, the ground will from them alone have received more enrichment than it will have lost by two good strawberry crops, which, if well managed, have enriched the pockets of the owner also.

"Out of the number that I have tried, only few have been named, but those have been the most noteworthy, and generally both the best and the types of classes. La Constante and Vicomtesse Hericarte de Theury, after several years of trial, may be said with certainty to he excellent in all respects, but the utmost hope that can be fairly entertained of them is, that they may equal Triomphe de Gandi which may be taken as the representative of them.

"Every year hundreds of seedlings are produced in this country, and as many thousands in France and Belgium, by good cultivators who know how to prepare them for exhibition, and consequently every exhibition is teeming with those that make a beautiful show, and many of them are really very good; but now, when the strawberry appears to have approached to near perfection, it must be one of rare excellence that will equal even our three or four best kinds. But the effort to produce better is just as laudable now as it was in the days of Keens, and the means with which to do it ample and well ascertained.

"In my next number I shall give precise directions for the preparation of the ground for fall and spring planting, for garden and field culture, and tell how to grow seedlings, and also describe some of the most important kinds, and in a subsequent number give directions for late and early forcing".
