Size, medium. Form, obovate pyriform. Color, dull greenish russet. Flesh, juicy, melting. Flavor, rich sub-acid. Ripens in November.

Among others whose characteristics give tokens of excellence, may be named: Doyenne de Nerckmunn, ripening in November - Beurre Scheidwiller, in October - Calinka, a fine large yellow fruit, in December - Beurre Benoist, in October - Beurre Giffard, in August - Baronne de Mdlo, in October - Fondante de Millot, in November - Bon Parent, in October - and Marechal de la Cour, in November.

The above are all worthy of consideration, and to which I might add others; but under

Before closing this article, which has now been extended beyond my original design, permit me earnestly to recommend the practice of raising new varieties from seed, a practice which I am happy to inform you, is becoming quite general in this region. When this branch of cultivation shall be more perfectly understood, I entertain no doubt but we shall be able to produce varieties rivaling in excellence the most celebrated foreign fruits. In support of these views, we might name among the instances which have been crowned with success, the efforts of Mr. Francis Dana, of Roxbury, who has the past year, from promiscuous seed, Trailed three varieties of pears of good character - two of which are entitled to particular commendation; one an early, the other a late sort. The Messrs. Hovey have also presented this season, a native variety of great beauty, and of fine quality, which promises to rank among the best of our early pears.

Unfortunately, the passion for new fruits, has placed so many under cultivation, that we are scarcely able to do justice to all. Instead of transferring, at once, scions of foreign varieties to healthy and mature trees for trial, our conclusions are too often drawn from imported trees, which are not fully established, or perhaps not adapted to the stock upon which they have been grafted.

During the past two years, we have witnessed the disastrous effects of unfavorable atmospheric influences. These are chiefly beyond our control; but cannot the other ills which vegetation is " heir to," be provided against? Cannot the tendency to deterioration, now so generally complained of, be arrested, and the pristine beauty and perfection of those fruits which were once the pride of our gardens, hut now remembered only as "out-casts," be restored, and perhaps maintained? Science has wrought wonders in other departments of knowledge, and why should it not aid the pomologist, as well as the manufacturer or the mechanic? Doubtless it can; but our efforts must be governed by the laws of nature - for, if there are scientific principles upon which terraculturc is founded, then no practice which is not based on these principles, can be depended upon with any certainty for success.

Tour readers will excuse this digression, but in view of your being about to address the good people of the Empire State on the great subject of Agricultural Education, I cannot refrain from expressing the hope, that not only New-York, but other stales, will take up this matter in earnest, and establish such systems of instruction as shall enable the cultivator, whether in the garden or in the field, to take his place by the side of the most favored class in the progress of improvement, for which our age is so distinguished.
