BOTANY OF LA SALLE COUNTY. 37 



Heavy seeds such as walnuts, acorns, &c, may be 

 carried to some distance by animals, which use them 

 as food and, swept along- by floods. Thus nearly every 

 plant has some means of extending- the area over which 

 It grows and these migrations are continually taking- 

 place. Since 1887 at least seven plant, before that 

 time unknown to the vicinity rf Ottawa, have located 

 here and to all appearances have come to stay. 



Such chang-es are very likely to occur along- lines of 

 railway for plants travel by rail as well as on the 

 wing's of the wind or on horseback. 



Localities of Special Interest to Botanists. 



There are in the county several localities of more than 

 ordinary interest to the botanist. Of these one is 

 located about two miles west of the court house on 

 what is known as the old Reddick farm, and has been 

 mentioned before. It is a part of Sect. 9 of Tp. 33, 

 R. 3, E. 3rd P. M. On this tract there is a great 

 variety of soils, both dry and wet, and as a conse-

Another locality is on the south side of the Illinois 

 river in South Ottawa township, in the woods and 

 along- the foot of the bluff, and just west of the C., B. 

 & Q. R, R., between it and the U. S. Silica Co.'s 

 lands. The ponds once existing- here have been partly 

 drained, and this place presents a less variety of veg-e- 

 tation than formerly, but one still finds much of inter- 

 est in a narrow space. 



A third district of very exceptiona 1 interest is found 

 on the west side of Covell creek, a fourth of a mile 

 south of the stone bridg-e on the river road. The vari- 

 ety of plants is great and some of them not common. 



A fourth and very interesting- locality is the bluff 

 and the narrow slope between it and the Illinois river, 

 in Deer Park township. The variety of plants, espe-
