None of these trees are common in our district, and only Celtis niav be regarded as frequent. These relatively southern trees are found not onlv along the Desplaines and its tributaries, where there is supplied a continuous habitat along the river southward, but also along ^J jHBg^ \^n^Hp^ ^m "^ ^^^^WEsA i m Fig. 14. — Flood plain of the Calumet river near Chesterton, showing the beginnings of ter- race formation, indicated more by the falling elm than by the topography, the Calumet and its tri...butary, Thorn creek. The occurrence of the tulip is full of interest, since it has been found thus far chiefly (perhaps onlv) in the vicinity of the dunes. Its occurrence has been noted especially at Chesterton along a small stream which empties into Lake Michigan at that point; the tulip has also been found away from present streams, but apparently in old valleys whose streams have been diverted by dune activity. The confinement of these southern trees to flood plains is not strange, since in such habitats are given the most congenial conditions that can be found in our area.
