GRADES OF NURSERY STOCK. 99 



or age. They form the cheapest class of nursery stock and 

 are used largely for starting windbreaks.

Transplants are seedlings that have been at least once trans- 

 planted and are designated by the size and number of times 

 they have been moved. They are higher in price than seed- 

 lings 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 permanent 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, bat 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. 



Forest-pulled Evergreen Seedlings may also be desirable but 

 too often they have poor roots or have been so injured by 

 poor handling that they are generally worthless. 



Forest-pulled Shade Trees sometimes grow very well, but they 

 are always inferior to good nursery-grown trees. They are 

 greatly improved by having their roots shortened two years 

 before they are to be removed, and when so treated grow very 

 well. 



TRANSPLANTING. 



Transplanting is simply the removal of the plant. It may 

 be to some permanent place as a park, lawn, or street, or it 

 may be done for the purpose of improving the root system 

 and to give the tree more room to grow. By shortening the 

 long roots the root system is made more compact and better 

 able to withstand subsequent removal. This may be done by
