BLACK SPKUCE. 



Picea nigra, Link. 



Picea mariana, (Mill.) B. S. P. See Britton & Brown, Vol. I, p. 55. 



Somewhat smaller than the red spruce. It prefers "sphagnum- 

 covered swamps." Propagation is same as for the red spruce. 



HEMLOCK, HEMLOCK-SPRUCE. 



Tsuga Canadensis, Carr. 



The cones of the hemlock mature in one year. They are small and 

 egg-shaped, drooping from little foot stalks when ripe. Gather in 

 October. After the seeds haA^e been removed from the cones, keep 

 them in a dry, cool room until spring. Sow broadcast in well pre- 

 pared beds. Rotten wood mixed with the soil will no doubt insure 

 better success. Moisture and shade are necessary for the young 

 plants. In two years they may be set out finally or transplanted 

 and set out when four years old. While the tree is found in moist 

 and cool places it seems to do well in other situations. The hemlock 

 is, when young, perhaps the slowest grower of all our forest trees und 

 will be the hardest to perpetuate as a forest tree. 



BALSAM FIR, BALM OF GILEAD FIR. 



Abies balsamea, Miller. 



Frequently found in the northern and colder parts of the State. 

 It makes a fairly rapid growth in well drained soil and can be used 

 for planting along roads or walks. The cones may be gathered in 

 autumn and dried slightly. The scales of the cones will have to be 

 separated from the seeds. They can then be treated as those of the 

 black spruce. 



LARCH, TAMARACK, HACKMATACK. 



Larix Americana, Michx. 



Larix laricina, (Du Roi) Koch. See Britton & Brown, Vol. L p. 54. 



The tamarack is a northern tree and is found only in the cooler 

 parts of the State. While it may be grown on dry soil it prefers and
