APPENDIX. 389 



The Norway Spruce (Abies excelsa), and Austrian Pine (Pinus 

 Austrica), are great acquisitions for our climate, being perfectly 

 hardy ; and with these and our native Pines, Cedars, Hemlocks, 

 &c., we must content ourselves until it can be ascertained, for a 

 certainty, what others may be depended upon. The Silver Fir 

 (Picea pectina) is a beautiful tree, much handsomer than our 

 native species, rather tender when young, but proves hardy when 

 well established. The young trees are imported from Europe, 

 and grown in our nurseries. They are not, however, very plenty 

 yet, as they are more subject to perish on their passage than the 

 Norway Spruce and some other young evergreens. 



The Chinese Arbor Vitas. Thuya Orientals. This is a 

 handsome evergreen tree, and has proved hardy, having stood un- 

 protected for the last three winters. The foliage is very beauti- 

 ful, and of a more lively green than the American species. The 

 only objection to it is, that, during cold weather, the foliage 

 assumes a brownish hue. 



Thuya aurea has singular foliage, of a bright yellowish-green 

 color. T.filiformis has weeping, pendant branches. T. varie- 

 gata has variegated foliage. All three varieties are novelties, 

 and, having been planted in my garden last spring, I shall have 

 an opportunity of witnessing the effects of the present winter 

 (185G) upon them. As the great body of snow on the ground 

 has given them a good protection, I hope to see them come out 

 bright. 



Taxus baccata and T. Hibernia, the English and Irish yews, 

 with the Thuyas, and some other evergreens, are in the process 

 of acclimation, and I hope I shall be enabled hereafter to report 

 them hardy.
