110 PRINCIPLES OF AMERICAN FORESTRY. 



GRADES OF NURSERY STOCK. 



Nursery stock of different kinds has come to be known 

 by such convenient names as seedlings, transplants, street 

 treeS; forest-pulled seedlings, etc. 



Seedlings are young plants, grown from seed, that have 

 never been transplanted, and are generally designated

by their size or age. They form the cheapest class of 

 nursery stock, and are used largely for starting wind- 

 breaks. 



Transplants are seedlings that have been at least once 

 transplanted, and are designated by their size and the 

 number of times they have been moved. They are higher 

 in price than seedlings, but with some kinds of trees they 

 are much more likely to grow, and may be well worth 

 the extra price. Evergreens, especially Pines, will seldom 

 do well unless once transplanted before being set in a per- 

 manent place. 



Street Trees include the trees of large size which are 

 used for street, shade, and ornamental purposes. To 

 be of the best quality they should have been transplanted 

 two or more times and have received some attention in 

 the way of pruning so as to give them a good form. Such 

 trees vary much in quality and price, but the best are 

 necessarily rather expensive. 



Forest-pulled Deciduous Trees of small size can often 

 be obtained at a very low price, and may be as desirable 

 as those that are nursery grown.
