RUSSIAN OLIVE. 



The Russian olive while not a large tree is desirable on ac- 

 count of its hardiness and adaptability to trying conditions. 

 The best one at Ogallah is twelve feet high, branches low, and 

 with its soft, silver-gray foliage makes a very attractive tree 

 picture. For lawn planting it is a very desirable addition to 

 the list of hardy species, and when planted in groups near 

 Osage, ash or other species with dark green leaves makes a 

 very striking contrast. 



COTTONWOOD. 



The cottonwood and other species of the poplar group have 

 not been particularly successful when planted upon the heavy 

 soil of high prairies. At Ogallah and at Dodge City the poplar 

 group is represented by a few dying trunks from which a few 

 sprouts are growing. 



At the Hays Station the young cottonwoods have made a 

 very strong growth during the few years since planting, and 

 furnish protection for species that succeed best in partial 

 shade. Along the creek bank and in ravines where the soil is 

 always moist the cottonwood is very valuable, producing in 

 some cases very good sawlogs in twenty-five years. In sandy 

 soils the cottonwood succeeds very well, and all along the val- 

 ley of the Arkansas and its tributaries the cottonwood is mak- 

 ing forests more rapidly than any other species. At Dodge
