ON TREES AND BIRDS. 



99 



wounds in trees. A few months ago I was in Boston, 

 and went to the parks to see the cement work that had 

 received condemnation. Well it might be denounced, 

 for any school boy could have done it just as well, and, 

 with a few minutes' drill, much better. This photo- 

 graph shows you that cement work is a perfect success, 

 if the work is properly done. This will heal over in 

 about three more years.
