TREE PROTECTION

Figure 1. A fallen evergreen tree with decayed trunk. Failure in this free blocked the high- 

 way and disrupted service by wire-using agencies. Inspection could probably have detected the 

 trunk weakness in the decayed tree. Note undisturbed sound evergreen in foreground which 

 was subjected to the same meteorological conditions. Photograph furnished by Boston Edison Co 



Figure 2. Advanced decay in this elm and a sleet storm combined to interrupt wire service 

 in this community. Damage by this fallen tree could have been even more serious; note prox- 

 imity of dwelling house and police and fire equipment. Photograph furnished by Boston Edison Co.
