This beautiful fir is abundant in the State of Maine, where I made a draw- 

 ing of the twig before you. It grows on elevated rocky ground, often near 

 streams or rivers. Its general form is conical, the lower branches coming 

 off horizontally near the ground, and the succeeding ones becoming gradually 

 more oblique, until the uppermost are nearly erect. The leaves and cones 

 become so resinous in autumn, that, in climbing one of these trees, a person 

 is besmeared with the excreted juice, which is then white, transparent, and 

 almost fluid. The leaves are solitary, flat, emarginate, or entire, bright green 

 above, and glaucous or silvery beneath; the cones cylindrical, erect, with 

 short obovate, serrulate, mucronate scales. It is abundant in the British 

 provinces, the Northern States, and in the higher parts of the Alleghany 

 Mountains. The height does not exceed fifty feet. The bark is smooth, 

 the wood light and resinous. The resin is collected and sold under the 

 names of Balm of Gilead and Canada Balsam.
