Excerpt: "Some of the flowers described are found along every country highway. It is interesting to note that these wayside flowers may usually be classed among the foreign population. They have been brought to us from Europe in ballast and in loads of grain, and invariably follow in the wake of civilization. Many of our most beautiful native flowers have been crowded out of the hospitable roadside by these aggressive, irresistible, and mischievous invaders; for Mr. Burroughs points out that nearly all of our troublesome weeds are emigrants from Europe. We must go to the more remote woods and fields if we wish really to know our native plants. Swamps especially offer an eagerly sought asylum to our shy and lovely wild flowers."
