THE CAROLINA POPLAR. 253 



relatively broader, and the teeth are coarser. Of this Western Cotton- 

 v/^ood there is but one species in Nebraska, contrary to the belief of 

 some of the old settlers. The names "White Cottonwood" and Yellow 

 I ottonwood" are not the names of different species. When the tree is 

 young and growing vigorously its wood is whiter and tougher, but as 

 it becomes older the wood takes on a yellowish color, and loses much of 

 its toughness, so that it can be worked much more easily. The iirst is 

 what has been called "White Cottonwood" and the second "Yellow Cot- 

 tonwood." 



CONCLUSIONS. 



'Name. — What shall we call our Carolina Poplar in view of the fore- 

 going discussion? To the writer of this paper the answer seems to be 

 quite evident that we can do no better than to give it the name by 

 which it was universally known in this country for nearly a hundred 

 years, and by which it is still generally known in Europe, viz., Populus 

 angulata. Apparently the tree as generally planted is staminate only. 



Shall We Plant It for Shade? — In spite of the fact that it is said to 

 be shorter-lived than the common Cottonwood, the Carolina Poplar can 

 be recommended for planting where shade and protection are wanted in 

 the shortest possible time. The fact that only the staminate trees are 

 propagated assures planters that they will not be troubled by the dis- 

 agreeable "cotton" which the pistillate trees of this genus produce. So I 

 answer Yes, to this question. 



Shall We Plant It for Fuel? — As in the foregoing question this may 

 be answered safely in the affirmative where the quickest returns are de- 

 sired. It must be remembered that this tree requires a good deal of 

 moisture, and that it will not thrive on dry soil. For fuel it should be 

 planted where it can obtain all the water it needs. Here again I 

 answer Yes. 



Shall We Plant It for Lumber? — From present information, the answer 

 to this question should be negative. The common Cottonwood will pro- 

 duce a larger tree in a given time, and is apparently longer lived, so that 

 where lumber of this quality is desired, it will be wiser to plant th« 

 Western Cottonwood, Populus occidentalis, rather than the Carolina Pop- 

 lar, P. angulata. So to this question I answer No.
