I send you a specimen of a dreadful weed, which we think was introduced in seed grain a few years ago. There seems to be no way of getting rid of it. It is called here "stink weed," I suppose from its disagreeable odor when pulled, or "French weed," much to the disgust of the French people, who call it "laviolette." Each plant produces immense numbers of seeds and it grows two crops in a season. People have tried leaving the field fallow for several years and have then several times had to plow up the green crop on account of the weed. It is all through the French half-breed settlements, and in some cases it has taken entire possession of the farms.

[The weed is the field penny-cress, one of the mustard tribe, which has great circular pods almost as large as a penny. It is known to botanists as Thlaspi arvenoe. We have never known it to be a serious pest before. It is a European weed which is sparingly naturalized in many parts of the country. It is an annual, and it would therefore seem that close and persistent culture, with a good rotation of crops, ought to hold it in check. - Ed].
