 wild than cultivated varieties. Following is a list of 

 the various seeds which were found : Blackberry, 

 chokeberry, juniperberry, pokeberry, partridgeberry, 

 greenbrier, Virginia creeper, bittersweet, holly, stra\v- 

 berry bush, false spikenard, wild sarsaparilla, sumac 

 (several species), rose haws, sorrel, ragweed, grass, 

 and asparagus. This list shows how little the bluebird 

 depends upon the farm or garden to supply its needs, 

 and indicates that by encouraging the growth of some 

 of these plants, many of which are highly ornamental, 

 the bird may be induced to make his home on the 

 premises.
