In recent years the common che<;tnut, formerly a conspicuous feature of forests and road- 

 sides in the northeastern United States, has almost disappeared, owing to the ravages of 

 chestnut blight (Endothia parasilvM), a disease for which no remedy has been discovered. 

 In an etTort to obtain blight-resistant chestnuts the Department of Agriculture has intro- 

 duced from China a number of interesting species. The one here shown is a large tree, about 

 100 feet tall, with a trunk 5 feet in diameter. The edible nuts are small, but J. F. Rock, 

 through whom the introduction has been made, reports them to be of sweet flavor. (Photo-
