the scales blunt, roundish, very thin, and 

 when ripe, ragged and torn at the margin. 

 Black spruce. Native of the Northern and 

 Middle States. 



In its native localities this tree often at- 

 tains seventy feet in height, though its 

 diameter is never great. It much resembles 

 the Norway, but is not pendulous. It 

 spreads horizontally like that species, but 

 has a darker hue. It will grow alike in the 

 lowest or the most elevated situations ; on 

 the rocky hill-side, or in a spot nearly 

 swampy. It seems to thrive best in a cool, 

 light loam. There are no very fine speci- 

 mens now at Bartram, the largest is thirty- 

 four feet high by twenty -four inches in cir- 

 cumference. 



For propagation, &c., see No. 1.
