The present paper is the third of a series of brief notes on the yearly changes in the re-vegetation of a soil area exposed by the building of a new levee in Des Moines in the spring of 1914. In the first paper the general character of the plant pioneers during the season of 1914 was discussed, with speculations as to their probable modes of travel. In the second, note was made of the replacement of the first year's dominating plant, Amaranthus retroflexus, by Chenopodium album, which gained the leadership through its earlier germination, and of the threatened overthrow of the latter by Lactuca scariola.
