New York, Feb. 10th, 1881. Editor of Gardener's Monthly - Dear Sir: - From a review in the Temps, Paris newspaper, I gather that M. Tisseraud, at present one of the French Ministers of State, owner of an experimental farm at Vincennes, near Paris, traveled some time ago in Sweden and Norway, and published a rather interesting "memoir" on vegetation in high latitudes. M. Tisseraud has found that wheat sown at Vincennes, imported from Norway, has ripened twenty-nine days before the regular French wheat; other cereals fifteen to twenty-five days sooner. This tendency to ripen early will last for some time, until the imported kind has got "acclimatized." Another remark of M. Tisseraud is that vegetables and flowers when forced in manure beds, greenhouses, etc, lose very much in flavor and odor, and sometimes by over cultivation even get insipid. That these same vegetables gain in intensity of their aromatic properties when cultivated in high latitudes, he instances onions, parsley, horse-radish, etc, and suggests that Norway seed grown in France could, for some time, produce as good results in France. That both qualities, however, aroma and early ripening, would gradually die out again.

Please, Mr. Editor, give us your opinion, and tell us if similar good results might not be obtained in this country by using seed from Canada, or Oregon, or Washington Territory, or even Norway.

[These facts are well known, and turned to profit in the United States. Peach trees forced for a few years in a hot-house, will attempt to bloom earlier when removed to a cooler climate, and the same variety of peach taken from the North to the South, will not bloom at the same time that a tree of the same variety will, raised in the South. Farmers continually have to get fresh seed of oats and other cool-country plants, as in time the kinds give out, and seedsmen usually grow their pea and some other crops far in the North, as they retain their best characters only for a few years. In short, it is as true of motion in all departments of nature as in the motions we see everyday about us. A wheel goes round for some time after we take our hands from it, and these life movements in plants show some results some time after the first impelling cause is out of the way. - Ed. G. M.]
