and compact habit, and the C. I. gracilis is another of a different 

 type, said to be more graceful even than the common form. These 

 seem likely to be the best adapted to small grounds. 



THE NOOTKA SOUND CYPRESS. Cupressus nootkaensis, Thuiop- 

 sis borealis. This strongly resembles the Lawson cypress, but is 

 more compact and less graceful ; about midway in general appear- 

 ance between it and a Siberian arbor-vitae. The form at the 

 bottom is globular in young trees, and the top conical. The lower 

 branches are not disposed to rest on the ground, like those of the 

 hemlock, Norway spruce, or even so much as those of the Siberian 

 arbor-vitas, but curve upwards more decidedly. The foliage re- 

 sembles that of the Siberian arbor-vitae, dark, but bright. Young 

 wood a dark purplish-brown. Growth more rapid than that of the 

 arbor-vitaes, but less than the Lawson cypress. When young it 

 closely resembles the latter, but may be readily distinguished by 

 handling the foliage, which is prickly, while Lawson's is soft to the 

 touch. The tree grows to great size northward of the Columbia 

 river, and has proved hardy, as far as we can learn, in all the States. 



THE WHITE CEDAR CYPRESS. Cupressus thyoides (Chamotcy- 

 paris). We have never seen this native species in cultivation, from 

 which we infer that it does not do well out of its native swamps. 

 Hoopes, however, mentions having seen very beautiful trees of it, 

 and one very perfect hedge ; and Emerson, in his " Trees of Massa- 

 chusetts," speaks of it as " this graceful and beautiful tree." As it 

 grows naturally in wet places, it is probable that it will develop its 

 beauty only in soil that is cool and moist. 



THE GOLDEN CYPRESS OR CEDAR. C. variegata. This, Sar- 

 gent thinks simply a beautiful variety of the white cedar, one that 

 is highly valued in England among variegated trees, and believed 

 to be hardy here. 



THE FRAGRANT CYPRESS, OR OREGON CEDAR. C.fragrans. 

 This tree is described in the proceedings of the California Academy 

 of Natural Science as follows : " This species bears the nearest 

 resemblance to Cupressus Lawsoniana, but differs from it most
