Red Juniper (Red Cedar). Valley of the Platte River, eastern 

 Nebraska, eastern third of South Dakota, central, western, and north- 

 ern Iowa, hillsides of southern Ohio, portions of southwest Missouri. 



Russian Mulberry. Sandy valleys of central Oklahoma, central 

 Kansas, and southern part of central Nebraska. 



Black Walnut. Valleys with rich, deep, well-drained soil in eastern 

 Kansas, Missouri, eastern Nebraska, southern Iowa; also valleys of 

 Wabash and Kankakee rivers in Illinois and Indiana. 



Bur Oak. Valleys of Niobrara and Missouri rivers in Nebraska and 

 South Dakota; immediate vicinity of Devils Lake, N. Dak. ; also valley 

 of the Red River of the North. 



Post Oak and White Oak. On waste land of gravelly or sandy 

 nature in eastern Oklahoma, Indian Territory, western Arkansas, and 

 on the same sort of land in Illinois, Indiana, and Ohio.

 Dakota, southeastern North Dakota, southwestern Minnesota, and 

 western Iowa. 



Tamarack. Lake and swamp district of Turtle Mountains, North 

 Dakota; marsh districts of Minnesota, Wisconsin, and Michigan. Not 

 likely to succeed where marshes have been drained in northern Illinois 

 and Indiana. 



Of the trees considered, the Hardy Catalpa has better prospects for 

 success, in its section, than any other. This is due to the ease with 

 which it can be managed, its rapid growth, and its adaptability to a 

 large category of uses. That it thrives in but a limited section is to 

 be regretted. Nevertheless, its territory is large enough for great 

 quantities of it to be produced. 



VALUABLE TREES OTHER THAN THOSE MENTIONED ABOVE. It is 

 freely admitted that there are many trees valuable for planting in the 

 Middle West not included among those given above. All the Elms, 

 Maples, Poplars, and Willows are omitted, and the writer knows well 

 that they have a high silvicultural value; but in a system of forest 

 operations instituted for profit and carried on under competition, such 

 trees can as yet have little place. They have been widely planted and 

 will continue to be planted for shade, shelter, and ornament, but not 

 for profit. In their influence upon the country they have a high value, 

 and as a class they are not to be lost sight of or disregarded in forest 

 planting; but since this article concerns itself only with those elements 

 that lend themselves readily to the immediate extension of forest opera- 

 tions, a general discussion of these trees is not included. 



EXTENT TO WHICH PLANTING MAY BE CARRIED. 



The area for profitable tree planting ten years ago was thought to be 

 limited to the Great Plains. It extends now to sections in the entire
