covered with checkered spots of thickened brown corky tissue, all of which 

 was hio;hly polished by the rubbing limb. A Baldwin apple which was 

 blown frequently against a sharp stub is shown in figure 57. The effect 

 in this case was that holes were punched in the skin of the fruit. Some 

 of the early wounds healed much as do the scars produced by redbugs, 

 but the later injuries produced a diiTerent kind of scar.
