There are considerable areas of flood-plain along the Galien River, and
except for the recently formed mud bars the flood-plains are heavily
covered with a mixed forest in which the linden, _Tilia americana_,
white elm, _Ulmus americana_, and sycamore, _Platanus occidentalis_, are
conspicuous species. Under this forest there are a few small trees, but
there is very little underbrush. The herbage also is sparse and, though
in a few places there is a considerable growth of ferns, grasses, and
sedges, and of other herbs, there are also many bare areas.

One of the significant features of the flood-plains, so far as the
mammals are concerned, is the flooding to which these areas are
subjected during the spring high-water. At that time the flood-plain for
a number of days or weeks may be covered with several feet of water.

During the period between July 29 and August 28 a total of one hundred
and seventy mouse traps set in the flood-plain forests along the
Galien River took for the first nights' trapping, twenty-two northern
white-footed mice and one house mouse. Short-tailed shrews, more
white-footed mice, pine voles, and a jumping mouse were secured on
nights after the first. Larger traps took during the whole period one
raccoon, one New York weasel, and two woodchucks. Several other
woodchucks and a number of red squirrels were seen. Ridges of moles
were numerous, but no specimens were secured. Tooth marks on an old,
partly fallen linden were probably made, perhaps a number of years
ago, by a porcupine.

Throughout the woods there are a number of small ravines. Thes
