THE PINE SUB-FAMILY. 183 



A very handsome and graceful tree from Sikkam, Nepal, 

 and Bhotan, where it attains the height of TO or 80 feet, 

 and is found in the former locality growing at an elevation 

 of from 9,000 to 10,000 feet, and in the latter from 0,500 

 to 9,500 feet ; but although it is a native of such high al- 

 titudes, and is quite hardy in England, its success in this 

 country is quite indifferent. 



In Sargent's description, he says : " We are somewhat 

 perplexed in making up our mind about the future 

 cpndition of this charming tree as to its availability. 

 If it succeed at all, it will certainly require a good deal 

 of coaxing. Our own specimen has been very various. 

 It has stood some winters well, and others, not as cold 

 but possibly damper, seemed to have destroyed it." This 

 has been the experience with almost all cultivators of 

 whom we have inquired, so that its ultimate success is ex- 

 ceedingly doubtful; and we would therefore caution any 

 one against undertaking its culture at the North, unless he 

 would be willing to lose a few plants in the experiment. 

 A few degrees further south will, we have no doubt, suit 

 it. The Gardener's Monthly says that although Gordon 

 may class it as " quite hardy and thus deceive American 

 readers, it will be killed easily by 10 below freezing 

 point, according to an American-made thermometer." We 

 believe that, with proper protection and suitable soil, it 

 will withstand a much lower temperature than the above. 



The Indian Hemlock very much resembles the Common 

 Hemlock (A.. Canaclensis) in general appearance, but in 

 the former the under side of the leaves is of an elegant 

 silvery-white color, so that, when disturbed by the wind, 

 they create a curious yet beautiful effect. This tree is 

 liable to the same disparagement as the A. Menziesii, in 

 regard to its proneness to lose its leaves. Dr. Wallich 

 says that " the slightest shake of the branch is sufficient 

 to detach them." We have also noticed this trouble, even 

 on very young plants.
