I CAN PRESERVE YOUR OLD TREES 



Mount Vernon 



One of my expert crews is now working on the 

 hisioric trees of Mount Vernon 



Proper feeding- of an old tree to give fresh vig^or 

 is an important part of my method of treatment. 

 After decay has been at rested and all dead or use- 

 less limbs removed, I give special attention to 

 starting- new growth. 



The art of tree surgery is ccmparatively new, 

 but it is based on scientific principles of plant 

 growth and a knowledge of the causes of disease 

 and decay. 



/ undertake the management of orchards, as 

 well as all kinds of crnamental plantations, 

 grading, surveying; making flower gardens 

 and herb aceous borders; and give profess 

 sional advice on estate management. My 

 crews consist of 75 expert workmen

 ion, based on years

 crowned and weakened branches bolted to a reinforc 

 ing rod. The tree now has a new lease of life
