The sloughs of the Little Miami and Miami rivers are similar in 
many respects to ox-bow cut-offs. They differ from them, however, in 
mode of origin, and in their almost universal connection with the river 
at both ends, at least during high water. Between the swampy depres¬ 
sion which may cross the landward side of a wide shore (fig. 4/), and 
the slough of almost river dimensions, there are all gradations.. 
The water of the slough flows very sluggishly, if at all, during dry 
seasons, but in times of flood is swift. In very quiet places, the water is 
covered with duckweed (Lemna minor) and floating species of Riccia are

occasionally found. The shallower parts are occupied by Sagittaria lati- 
folia, Eleocharis, Typha latifolia, Leersia oryzoides, and Echinochloa Crus- 
gain (fig. 51). 
Whether the slough is full of water, or merely swampy, and occu¬ 
pied by swamp herbs, the margins are bordered by the typical marginal 
vegetation of rivers. In this respect, the sloughs resemble rivers with 
their well drained margins, much more than they resemble ox-bow lakes,
