Nature Bulletins Pub. by the Forest Preserve Dist of Cook County

Many years ago, the Forest Preserve District of Cook County published a series called "Nature Bulletins". Recently we gained access to a large number of them which we hope to reprint here. Some may be typed, and some uploaded as JPG. They were written by Roberts Mann, then Supt. of Conservation and they date from the late 1940s thru the middle 1950s. While they are old, the information contained is still factual and relevant. I think nature lovers will be happy to see these entertaining and informative entries resurrected.
