124 THE ADVENTURES OF A NATURE GUIDE 



On scores of occasions during my years of camp- 

 ing over North America lightning appeared to see

 I once held the common and preconceived notion

Lightning strikes every known species of tree. 

 It not only strikes trees that stand on summits but

In this connection it is said that trees rich in
