 direction. Now it is plain that the section of the root system affected 

 by the water was unable to supply the corresponding section of the 

 branch system with food, and the latter consequently died. The soil 

 conditions on the left of the tree are somewhat better — the result of the 

 proper working of the drain on that side, although it Avill be observed

 growth for six or seven years. By this time the roots have become 

 firmly established in the subsoil, but as winters of heavy rainfall are
