TSUGA CANADENSIS. 463 



" Gardeners' Chronicle " loc. cit. supra, together with the figure of 

 a tree sketched in Nepal : 



"I first met with this graceful tree on the hanks of the Tambur river 

 in eastern Xepal and have described it in my Journal as a beautiful 

 species forming a stately blunt pyramid with branches spreading like 

 the Cedar but not so stiff, and drooping gracefully on all sides ; 

 its surrounding scenery is as grand o,s any depicted by Salvator Rosa; 

 a river running in sheets of foam, sombre woods, crags of gneiss rock, 

 and tier upon 4ier of lofty mountains flanked and crested with groves 

 of black Fir, Abies Webbiana, terminating in snow-covered rocky peaks. 

 Here one individual was measured and found to be 20 feet in girth 

 at about five feet from the ground; on another occasion in the Lachen 

 valley of Sikkim, I measured a Hemlock Spruce that was 120 feet in 

 height and 28 feet in girth, nor were these very exceptional dimensions 

 though they greatly exceed what prevails in the Darjeeling district. 

 The Himalayan Hemlock Spruce does not extend westwards beyond 

 Kumaon where, according to Maddon, it attains a height of 70 to 80 feet 

 and yields inferior timber ; eastwards it extends into Bhotan where 

 Griffith met with it at 6,500 to 9,500 feet, which is a considerably 

 lower elevation than it affects in Sikkim where its inferior limit is 

 about 8,000 feet, and its superior 10,000 feet. The wood in Sikkim 

 is but little used, not being durable, but the bark is employed for 

 roofing huts." 



Seeds of Tsuga Brunoniana have been frequently received in this 

 country ; the experience of the past forty years has, however, but 

 too surely shown the futility of attempting to acclimatise this fine 

 tree in Great Britain unless, indeed, a hardier race can be obtained 

 from seeds gathered near the superior limit of its vertical range or 

 from the few trees that have become established in this country.* 

 In exceptionally favoured localities such as are to be found in 

 Devon, Cornwall and the south of Ireland, Tsuga. Brunoniana lives 

 on for a number of years but rarely shows anything like the 

 stately form it assumes in the Himalayan valleys. 



The species was dedicated by Dr. Wallich, for many years Director 

 of the Botanic Garden at Calcutta, to his contemporary Dr. Robert 

 Browri, the most eminent British botanist of his time. 



Tsuga canadensis. 



A tall graceful tree with a pyramidal crown, at its greatest 

 development 75 90 feet high but usually much less ; in the dense 

 forests of Canada free of branches for three-fourths of its height, in 

 more open places furnished with branches nearly to the ground. Bark 

 of old trees ash-brown with broad longitudinal fissures exposing a pale 

 inner cortex, and narrow transverse fissures by which the outer cortex 

 is broken up into irregular plates. Branches slender, spreading, the 

 lowermost sometimes more or less deflexed by the weight of their 

 appendages : ramification lateral. Branchlets flexible and drooping at 



* The largest known to the author are at Dropmore and Strete Ralegh.
