two of the purposes to which it is put. He says : "Next morning, 

 looking about our neighbourhood, we re-entered our canoe, hollowed 

 out of Cwpressus nutkaensis, the mats we sat upon being made of the 

 fibre of the same tree, ropes of the same material, and occasionally of 

 Thuya plicata." 



Cliamsecyparis nutkaensis is perhaps not to be seen in Danish 

 gardens much older than 30 years, and of some 20 feet in height. 

 One plant, just now measured, has attained a height of 27^ feet 

 and a girth of 1 foot 6 inches. It was planted in 1870. This species 

 thrives at Christiania, and even at Upsala (59° 52^).

Very large plants of Chamsecyparis pisifera are not to be found 

 yet in Danish gardens ; still a specimen, planted in 1879, has attained 

 a height of 12 feet.
