 friend of the smaller brook trout in fact, takes him in

 the presence of rainbow trout in large numbers has evi- 

 dently been established. The Pere Marquette River is 

 practically the same, and there are other streams in 

 Michigan where rainbow trout are quite plentiful. They 

 seem to stay in the Michigan streams and do not go 

 out into Lake Michigan. Large quantities, however,
