Academy of Science, Dr. Engelmann has gone more extensively into 
the different questions relating to the North American species of Abies.” 
Until this very needful revision appears, the following characters, 
drawn from my own specimens, may serve to designate more particularly 
our welcome newcomer from the mountains. 
Abies subalpina Eng., n. sp. Tall and slim, 80 to 100 feet high, 
often 50 feet without branches; bark smooth, white, and covered with 
vesicles to near the base ; leaves 6 to 12 lines long, less than a line broad, 
hot twisted near the base, bisulcate and somewhat glaucous on the lower 
(outer) side, short-pointed, obtuse or slightly emarginate, those on the 
lower branches 2-ranked and spreading, those on the upper scattered, 
crowded, and more or less appressed, shorter on fertile than on sterile 
branchlets ; cones 21 to 3 inches long, 1} to 2 inches thick, solitary, 
erect, ovate or oblong, obtuse, greenish ; scales 6 to 10 lines long and 
about as broad, horizontal and close-pressed, broad-cuneate, unguiculate, 
the rounded upper margin somewhat reflexed and resinous, pubescent ; 
bracts short, white with a dark base, erose-dentate all round, their 
slightly elevated summits furnished with a strong mucro; seeds large, 
the wing covering nearly the whole surface of the scale; sterile aments 
2 inches long, 3 lines in diameter, marked longitudinally and somewhat 
_Spirally by the dark centres of the otherwise light brown mucronate

Hasits or rae Wurre-Foorep Mouse. — The white footed mouse 
(Mus leucopus) sometimes takes up its abode in deserted bird’s-nests 
Audubon, in his work on the Quadrupeds of North America, speaks of 
this peculiar habit. He says it has been known to take possession of 
deserted bird’s-nests, such as those of the cat-bird, red-winged starling, 
Song-thrush, and red-eyed flycatcher. One day toward the end of Au- 
gust, 1875, I found one of these mice in the deserted nest of a red-eyed 
flycatcher (Vireo olivaceus) ; it was on the border of a thick forest in the 
Blueridge Mountains, Monroe County, Pa. The nest was situated near 
the extremity of one of the limbs of a sapling or young tree, a few feet 
em the ground. The mouse had completely stopped up the inside of 
hest with dried grass, leaving just enough room to squeeze itself
