tures, and along roadsides and railroads throughout the state except in 

 the northern counties where it may be rare or absent. Some authors 

 believe this species to be adventive from the south. Our earliest authors 

 list it and Dr. Clapp in 1852 says : "Very common in the vicinity of New 

 Albany." I am considering it a native, at least in the southern part of 

 the state.

 quent to common on the muddy shores of sloughs, ponds, and our larger 

 streams. It is to be noted that this species is rapidly migrating. I have 

 known well the shores of the Wabash River near Bluffton for a distance 

 of five miles since 1880. The first colony of this species was noted in 1897 

 and it is now common all along the muddy shores and on the muddy bars 

 in the river. In the early history of the state our streams were clear and 

 when the forests were removed the streams became muddy and sediment 

 was deposited on the shores and on the gravelly and rocky bars which 

 made a suitable habitat for this species. This same thing is true of several
