Digging Compared with Chemical Treatment 
A.— Barberry sprouts of about three years' growth near Marshall, Dane County, Wis. (1921). 
These bushes had been cut down twice. Thev were cut down a third time in the spring 
of 1922 
B.— Portion of a hillside pasture near Galena, 111. Here many sprouts were treated with salt, 
evident as white patches on the ground. The outcropping limestone and the trees and 
stumps made effective digging almost impossible
