deuber: soil fertility and root development 
75 
A tree needs good anchorage and feeding for the development of a 
deep and a well extended root system is the most satisfactory solution. 
Even in the case of trees growing where deep rootage is impossible, it is 
often feasible to obtain a considerable extension of the roots by feeding 
and a corresponding increase in stability. 
Do not allow the more brittle trees to grow where they are likely to 
jeopardize public safety or property interests. 
Healthy trees and therefore strong trees can be secured only by pro¬ 
tecting the various parts, especially the leaves from attack by insect 
pests and fungous diseases and the trunk and branches from invasion 
by borers. The work of the last greatly facilitate invasion by the 
dangerous wood rots. 
The shade tree needs care throughout its existence in much the same 
way as the fruit tree. 
There are numerous excellent articles in current publications on the damage 
caused by the hurricane. No attempt has been made to list these. There are a number 
of special illustrated booklets covering various phases of storm damage and since 
these are not readily located, they are listed below:

SOIL FERTILITY AND ROOT DEVELOPMENT 
By Carl G. Deuber, Yale University , New Haven, Conn. 
The New England hurricane completely destroyed many thousands 
of shade trees, it also left a greater number severely injured and weak¬ 
ened. The shade tree problems in the next several years will un¬ 
questionably be complicated by the greatly increased number of weak¬ 
ened trees with various degrees of damage to the top and root systems. 
The trees blown down and reset and those which were blown to a leaning 
position and which have been pulled upright will have many large an¬ 
choring and supporting roots broken as well as numerous smaller roots 
torn off or dried out. The extent of the damage to the roots of trees 
that withstood the storm but were fiercely lashed and rocked by the
