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, Ulmiis 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
