The district around Chicago might seem toone not personally acijuainted with the countryas a poor one for botanical collection, consistingmainly, as it does, of Hat prairie; but our citybotanists familiar with the region, have foundit ((uite fruitful in species. Taking the city as a centre, within the areaof a circle swept by a radius of thirty miles, Iam inclined to think a greater variety of plantsmay be collected than within the same space inany other portion of this State. In the barrensandy soil along Lake Michigan we find plantssuggestive of the sea shore, including a numberof species limited elsewhere to the Atlanticcoast, or the neighborhood of saline deposits inthe interior. Passing to the prairie within fiveor miles of the city, along the lines of severalrfiilroads, where a strip of land has been rescuedfrom tillage and protected Ironi cattle, we
