 during the summer months. 



In cases where, owing to unavoidable

 west are rather close, provided there is no 

 drip on the garden from their branches, much 

 may be done to overcome the root trouble. 

 A narrow trench sunk rather deeper than the 

 roots of the trees descend, and filled with rough 

 concrete, will form an effectual barrier. 



Now, having decided that the site must 

 not be overshadowed nor shut in by trees, 

 the next point to be considered is the aspect. 



This is all-important. The problem is to
