seldom planted because of the difficulties encountered in transplanting 

 and raising young trees. 



BLACK LOCUST (Robinia pseuilocana} A rapid growing, short- 

 lived, light foliaged tree standing considerable drought and alkali. It 

 makes a handsome .-hade live and is much used in the Panhandle and 

 West Texas. It has a number of drawbacks, however, since it suckers 

 badly and creates considerable litter with the seed pods. Furthermore, 

 in places it is being exterminated by the locust borer (Cyllene robinae). 

 Where the borers are not present it is a valuable lawn and street tree. 



BLACK WILLOW (Salix nigra) A fast growing tree useful near 

 water. It is not long-lived, and is too susceptible to disease and insect 

 attacks to make it a good shade tree. Moreover, it is untidy in appear- 

 ance and the shallow roots are ,a nuisance, breaking up walks, killing 

 out grass, and when planted too close to ditches the roots tend to 

 fill them up. 



CHINESE TALLOW TREE (Sapium sebiferum)The tallow tree 

 is an Asiatic species which does well in Texas. It makes a medium rate 

 of growth but does not reach any great size. It has leaves similar to 

 cottonwood, making a rather attractive small tree for narrow streets. 



PAGODA TREE (Sophora japonica) An Asiatic tree of medium 

 size which makes a moderately fast growth and stands a dry climate. 

 The pagoda tree is a good tree for narrow streets in West Texas. 



JAPANESE VARNISH TREE (Sterculia platanifolia)The Jap- 

 anese varnish tree is another Asiatic tree which has found favor in this 

 country. It is a moderately fast growing tree with smooth, light green 

 bark and large leaves, resembling those of the sycamore. It does not 

 form a full crown, but the dense clusters of large leaves on the ends of 

 the branches make a satisfactory shade. This appears to be a desirable 

 shade tree. 



BALD CYPRESS (Taxodinm distic'hum)T}ie cypress is a tree best 

 suited to swamps but occasionally excellent specimens are found along 

 road sides and in towns. The cypress is best used where formal effects 

 are desired. It is a rather slow growing tree but a long-lived one, not 

 affected by insects to any extent. 



SALT CEDAR, TAMARISK (Tamarix spp) There are several vari- 

 eties of salt cedar all introduced from foreign countries. They are re- 

 markably hardy and make a good growth. Most varieties are shrubs 

 but with training some may assume tree form. They have light feathery 

 fcliiage similar to the cedars but the leaves are shed in the winter time. 

 Only valuable for street purposes where other trees do not grow, par- 

 ticularly in the Trans-Pecos region. 



BASSWOOD, LIXDEN (TiVn <n,n r'lrana) The linden is a native 

 of East Texas that makes a medium sized tree of good form. It is an 

 excellent shade tree but requires considerable moisture. 



BOIS D'ARC, OSAGK ORAXGE (Toxijlon pomifemm)The hois 

 d'arc is a tough tree, making a slow to average rate of growth. It has 

 dark green lustrous leaves forming a broad rounded crown. The* fruit
