MR. AND MRS. RICHARD HOGER HONORED 
This summer two members of The Illinois Audubon Society receive 
the unusual distinction of a letter of commendation from the Presider 
of the United States. 
For many years the Hoger family has maintained Willowbroc 
Wildlife Haven, a zoo and nursing home for native Illinois birds ar 
mammals on Park Boulevard in Glen Ellyn, one mile south of Roos 
velt Road. The Haven is now part of the DuPage County Forest Pri 
serve District. The Hogers began their mission of rescuing wi 
animals and nursing them back to health a dozen years ago at tI 
Calumet Cinder Flats south of Chicago, where they undertook to sa\ 
the lives of hundreds of poinsoned shorebirds. Richard Hoger serve 
in 1961-1962 as a Director of the I. A. S., and the couple has receive 
an I. A. S. Conservation Award. 
The story of their wildlife rescue work was published in a ni 
tional magazine this summer, and as a result President Nixon se 
the letter reproduced on the opposite page. 
TROUBLE IN MINNESOTA 
Lake Superior, largest of the Great Lakes, is “beginning wrinkles of 
says A. F. Bartsch, director of the Pacific Northwest Water Labora 
The pollution of the lake is largely the result of the activities of the 
serve Mining Company of Silver Bay, Minnesota, which each day dischi 
about 60,000 tons of taconite tailings into the lake. 
At a recent convention on water pollution, the Minnesota Conserv 
Department and the state’s Pollution Control Agency turned out to be 
main apologists for the mining company. However, it is hoped thai 
Army Corps of Engineers will not renew the company’s permit to ¢ 
in the lake. : 
Another gloomy note—exploration for minerals began this summ( 
large sections of the Boundary Waters Canoe area, a million-acre fe 
Wilderness preserve. Under the Wilderness Act, all mining in Wilde: 
area will be banned after 1983; however the Government did not buy 
mineral rights to the area; so mining could legally be carried out. To 
vent mining, Congress would have to pass a special appropriation uD 
up the mineral rights.
