USE OF DDT MAY BE CURTAILED 
Persistent pesticides, DDT and dieldrin in particular, have been suspected in 
the mortality of coho salmon fry in Lake Michigan. On July 31, conservation 
officials of Michigan, Indiana, Illinois and Wisconsin (the four Lake Michi- 
gan bordered states) got together and made an agreement to try to bring about 
better control of pesticides. They will work for more research, adoption of 
new laws and further water quality standards. Noting the coho fry problen, 
they warned that the control of pesticides must improve to prevent disasterous | © 
consequences for Lake Michigan. The Michigan Department of Conservation, 
under Ralph A. MacMullan as Director, was prominent in bringing about this 
agreement. 

In july, 1968, the Illinois Natural History Survey dropped its recommendation 
of DDT for Dutch Elm disease. A slip was stapled to page 15 of its Circular 
53, "Dutch Elm Disease in Illinois", which reads: "The Illinois Natural | 
History Survey no longer recommends the use of DDT in Illinois for the control 
of Dutch Elm disease and elm phloem necrosis. Because of its long residual 
effect, DDT can be hazardous to animal life. DDT is a possible contaminant 
of agricultural crops adjacent to treated areas and of streams flowing* 
through or near treated areas",

RIDGWAY BIRD CLUB HAS INTERESTING PRQGGRAM 
The members of Olney's Ridgway Chapter of the I.A.S. had the opportunity 
to examine the three volume work by their chapter's namesake, the ornitho- 
logist Robert Ridgway. One of their members, Wayne Taylor, was fortunate 
enough to find a copy of "North American Land Birds" by Baird, Brewer and 
Ridgway in a Chicago bookstore. Taylor explained the methods used in print- 
ing the plates and hand-coloring the illustrations. 
; Vera Shaw, gave a report on the I.A.S. meeting in Kankakee and told about 
the two properties in southeastern Illinois which have recently been ac- 
quired by the Illinois Chapter of the Nature Conservancy. The two areas are 
the Ica Marks Preserve in Edwards County and Big Creek Woods, which is 2% 
{ miles south of Olney on Route 130. 
Dick Thom displayed some maps he has made of Big Creek Woods that show the 
topography and vegetation in the area. He also showed some slides that he 
took on a canoe trip in northern Minnesota and a back-packing trip to the 
Porcupine State Park in Michigan's Upper Peninsula.
