"You have cut off the supply from the top." 



Good conclusion, drawn from a self-evident fact, 

 Bessie. Here is the photograph of the top of the same 

 tree that you have in the last lesson. The dead branch

 large trees that are transplanted where the main roots 

 have been destroyed; a "dead center" often follows. 



"Lots of trees have their roots cut off in laying 

 sidewalks in the cities, do they not? "

 is best, in narrow streets, to plant the shade trees inside 

 the sidewalk on the lawn, and they should not be less 

 than four feet from the sidewalk, nearer than that
