The evidence
“The extent to which operations, have been carried on necessitates going further up the stream for available timber, although there is yet what may be termed an abundant supply. The first cutting of lumber on this stream, of ■which there is any record, was by government soldiers, in 1828, at the building of Fort Winne- "bago. In 1831, a mill was built at Whitney's rapids, below Point Bass, in what was then Indian territory.”
