At the suggestion of Dr. Stephen A. Forbes, Chief of the State Natural HistorySurvey, the writer in 1921 attempted to supplement Mr. Baker's studies from a purely entomological view-point. The stream was examined at short intervals, from above the source of pollution near Crystal Lake, Urbana, to just beyond the union of the Salt and Middle forks nearHillery in Vermillion county. Illinois. A total of thirty-three stationsvwere established, corresponding rather closely with the collecting points chosen by Mr. Baker and with the bacteriological stations of the Illinois Water Survey. The collections of insects taken at the various stations are recorded later in this paper.
