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: 
Three trees to be planted where nothing else will grow ; easily 
transplanted, growing rapidly, but shortlived, liable to injuries, root-sprouting, 
soon scraggy looking unless specially attended : 
Silver Maple. Carolina Poplar. Box Elder. 
(Acer dasycarpum.) (Poplus monlifera). (Negundo aceroides.) 
Four trees, among the best for street and lawn:
