356 ARBOR DA Y MANUAL. 



NEW YORK STATE PROGRAM, 1889. 



Summarizing the elements of success in tree planting, they are : 



1. Trees suitable to soil and surrounding conditions ; 



2. A well-developed root-system, kept in living condition ; 



3. Wide holes and mellow soil ; 



4. Firm packing of soil around the roots. 



Choice of kinds. Leaving out conifers which require more careful handling 

 and better situations than are as a rule to be had on occasions like that in view 

 there are over one hundred indigenous species to choose from for planting on 

 the Atlantic side ; of these thirty to forty might deserve attention for Arbor Day 

 tree planting, according to climate, soil, and situation, or object. It is best to 

 limit the choice for this occasion to trees of recognized merit native to your 

 locality ; opportunities will vary the choice. It is only possible here to name the 

 following selections, which admit of a wide application in the Atlantic States :
