Why Davey Tree Surgeons only are 
good enough for You 
The trees that beautify the grounds of the 
U. S. Capitol and other public places are too 
valuable to be practiced upon or experimented 
with. 
The government officials want assured 
results. After a careful official investigation 
the Davey Tree Experts have been entrusted 
with this important work. 
The result of the policy of employing real 
Tree Surgeons is seen in the following conspicu¬ 
ous fact. 
The latter part of last July there swept 
over Washington the worst storm in fifty years. 
While thousands of beautiful trees were torn 
to pieces, not one tree which had been treated 
by Davey Tree Surgeons was materially injured.
