other points for example, Fort Collins and Denver are equally 

 thrifty specimens. In many cases, however, the winters prove too 

 severe and the trees die in a few years. Because of its rapid growth 

 and the durability of its wood, hardy catalpa is an exceedingly valuable 

 tree, but it can not be recommended for general planting even in the 

 South Platte country. 



WESTERN YELLOW PINE. 



Western yellow pine is especially adapted to sandy soils and is being 

 planted by the Government in the sand hills of Nebraska. It can be 

 recommended for general planting in both valleys. The wood is hard 

 and fairly durable and is useful for many purposes. 



JACK PINE. 



This tree is native to the north-central and northeastern United 

 States and Canada. It is especially adapted to sandy soils, and is 

 being extensively planted in the sand hills of Nebraska. It is also 

 suited for planting on similar soils in these valleys. It grows more 

 rapidly than most conifers, and is a useful tree for windbreaks and 

 shelterbelts. The wood is slightly inferior to that of western yellow 

 pine. It is used for fuel and coarse lumber and, if treated with chemi- 

 cal preservatives, is fairly satisfactory for posts and ties. 



KOOKY MOUNTAIN JUNIPEK. 



This is the western type of the tree commonly known as "red 

 cedar," from which it differs in size, being generally smaller; but it is 

 even more hardy. It has a wide natural distribution in the foothills 

 of the Rockies and west, and is also found on the bluffs bordering the 

 table-lands in the North Platte Valley. Farther east, in Nebraska, it is 

 found in company with willow and cottonwood in the sandy soils of 

 the Platte River bottom. It will succeed well on the upland soils in 

 these valleys. No better tree can be used for forming permanent 

 windbreaks, for it branches low to the ground, and since it holds its 

 leaves the year round, it is fully as effectual a protection in winter as 

 in summer. It should not be planted adjoining orchards, however, 

 since it is subject to a fungous growth which injures fruit trees. The 

 durability of its wood is well known, and on this account it is planted 

 for fence-post production. It is also used extensively for ornamental 

 purposes.
