the work has been well done, enough fibrous roots will be 

 formed in this soil to render transplanting successful. 



American Chestnut (Castanea dentata). This tree grows 

 to the greatest perfection in many sections of the United 

 States, and in soils where the elm, maple, ash, and oak 

 do not thrive. It is free from disease * and the attack 

 of insects, rapid in growth, with a beautiful dark green 

 foliage, and its abundant flowers in July make it an attrac- 

 tive feature of the landscape. Its fruit, too, is valuable 

 and might be made a source of some profit if properly 

 managed. Like the oak, it is difficult to transplant, and 

 it has the same tendency to branch low when planted 

 in full exposure, but these objections can be remedied in the 

 same manner as with the oak, and its broad-spreading 

 habit with proper treatment makes it a close rival of the 

 American elm. 



White Hickory or Shagbark (Gary a ovata). On very 

 heavy soils this tree may become a very good street-tree, but 

 on light land it would be of no value. Its habit of growth 

 is tall and upright. It has bright green foliage, changing to a 

 bright golden color in the autumn, and is generally free from 

 insect or fungous attack. It is even more difficult to trans- 

 plant than the oak or chestnut, but it may be started from 

 seed where it is to grow or be prepared for transplanting in 

 the nursery or fields, as is the oak or chestnut. 



Black Walnut (Juglans nigra). No grander tree can 

 be found among those native of the United States than the 



* Since this was written the chestnut bark disease has appeared in 

 many sections of the country, and those who have made the most care- 

 ful study of it are fearful that it may spread so as to do serious injury. 

 This disease attacks the bark of the trunks, main branches or small 

 twigs, stopping growth and killing all parts outside of that attacked. 

 The foresters of the States where the chestnut is abundant are watching 

 the development of the disease and have issued bulletins as to its prog- 

 ress and the best remedies. Send to your experiment station or to the 

 Department of Agriculture at Washington.
