LETTER OF TRANSMITTAL. 



To Hon. J. T. Rothrock, Commissioner of Forestry: 



Dear Sir: I have the honor to submit herewith the following notes 

 on the "Propagation of Forest Trees Adapted to Pennsylvania." 



Recognizing the needs of our farmers, I have endeavored to pre- 

 sent in a brief and clear way such facts and methods as will bring 

 reasonable success 'to 'the inexperienced planter, without making 

 necessary any large expenditure of money. The nurseryman or the 

 forester may find nothing new and may even take exception to many 

 statements. 



The botanical names of the trees and their order, for the greater 

 part, is in accordance with Gray's "Manual of Botany," sixth edi- 

 tion. In addition I have added those given by Britton and Brown 

 in their "Flora of North America and Canada," when differing from 

 the nomenclature of Gray. 



Very respectfully, 



GEORGE H. WIRT, 



Forester. 



Harrisburg, Pa., February 1, 1902.
