The cedar waxwing probably was responsible for scattering the 

 barberry. The grove of Mr. Hedden was used by Miss Elder to 

 study the bird population of the region because of the interesting 

 species found there. It was not the only grove in that vicinity, 

 since Mr. Elder, who ran a nursery in Concord, had planted a fine 

 lot of trees around his home. The soil of the region is a black prairie 

 soil and fifty years ago was a virgin prairie. It may be of interest 

 to note here the establishment of other shrubs and trees in the 

 Hedden grove. I note first of all the Rubiis odoratus which is

scattered over a rod in the south grove, the elderberry (Sambucus 

 canadensis) in both groves, the snowberry (Symphoricarpos oc- 

 cidentalis), the chokecherry (Pninus virginiana), the black cherry 

 (P. serotina) and the poison ivy (Rhus Toxicodendron). The 

 following trees were found in the grove : Acer saccharinum, Popxihis 

 dcltoidcs, Acer negnudo, Salix alba, Fraxinus viridis lanceolata, 

 Pyrus auciiparia, Juglans nigra, J. cinerca, Larix decidua, PiniiS( 

 strobus, Picea alba, P. excelsa, and P. aiistriaca. 



TIic Wild Barberries at McGregor, Postz'ille and Clermont. — I 

 will only consider these found on the Chapin and Guttheil places in 

 McCjregor. In the former place the plants occurred in the rocky 

 limestone area, 150 feet from an old cellar where once stood a house. 

 There was no evidence here of any barberry ever having been 

 cultivated. It is certain, therefore, that the wild plants must have 

 been brought from some wild plants up further in the hills. The 

 j)lants were seventeen to twenty-five years old. There were a 

 number of young plants around the old bush which was loaded with 

 fruit. 



The Guttheil barberry in McGregor is also of interest. A family 

 by the name of Reynolds lived on the place and when the Guttheils
