It is estimated that during the period of this study ending in 1939-40 about 7,500 red foxes were caught annually in Illinois, table 8, roughly 75 per county, or an average of about 1 to each 7 or 8 square miles. An immature red fox is pictured in fig. 14. Income From Red Foxes.—The av- erage annual income from red foxes for the period of this study ending in 1939- 40 is estimated to have been about $30,- 000, table 8; or about 50 cents per square mile; roughly, $300 per county. This annual income from red foxes is estimated to have averaged slightly more than $1 per Illinois fur-taker. Numbers of Gray Foxes Caught.— The average annual catch of gray foxes for the period of this study ending with 1939-40 is estimated to have been about 3,800, table 9; or 1 to each 14 or 15 square miles. Most of the catch was concentrated in the hilly and timbered areas along the Mississippi and Ohio rivers. Gray foxes are now present in relatively few counties in Illinois; they were once more widely reported. Income From Gray Foxes.—The average annual income from gray foxes for the period of this study ending with 1939-40 is estimated to have been $8,600, table 9; or 15 cents per square mile. LONG-TAILED WEASEL Distribution. — The average annual catch of weasels per Illinois fur-taker, according to fur-takers' monthly reports, is greatest in an area extending from the northeastern corner of the state southwest- ward toward Knox County, fig. 15. Zones of moderate catches lie on either side of Table 10.—Weighted per cent of Illinois fur-
