Abies Eiiglemanni, Pany. In the liiglier Alpine regions, about Alpine prairies, etc. 

 A stately tree of small diameter, growing so densely in its peculiar habitats, that no 

 trunk can fall to the ground alone. Circular areas of an acre or two are frequently 

 seen in the Alpine heights where tlie entire growth has been prostrated and lies a 

 l;il)yrintli of trunks that have apparently fallen in every direction, evidently caused by 

 the action of a circular wind, no eifects of which are to be seen outside of the pros- 

 trated areas. This tree in fruit, etc., much resembles A. Me)iziesii of the coast/egion, 

 and is probably no more than a high mountain form of it. 



Abies Menziesii, Dougl. This tree abounds in the coast regions to a limited extent 

 where it fruits abundantly. It is not known to be of much importance to the country. 

 Ta,vus hrecfulid, Xutt. Grows nearly or (juite upright and attains a diameter of a 

 foot or over, but is low and scraggy, with spreading, drooping limbs. The foliage is 

 bright green and ornamental. It is used for fence posts chiefly on account of its dura- 

 bility, but it is scarce and of no great value to the country on that account. The berries 

 are red and edible when ripe in September. 



Juiiiperus rommimis, L.. var. alpinm, Pari. This is a trailing form of the species, 

 never rising from the ground but trailing and rooting from its limbs, forming large 

 clumps 10 to 20 feet in diameter. Occurs at the limit of trees on Mt. Hood. 



Oipressus JSfutkanus, Hook. A low branching shrub in the Alpine regions of Mt. 

 Hood. Identification doubtful. 



Thuja gi(/antea,l>intt. Called cedar by the inhabitants. Is a tree of average size 

 and height, 1 to 4 feet, generally 2 to 8 feet in diameter and 00 to 150 feet high. In- 

 habits the mountain ranges, reaching the Williamette valley at some localities. It is 

 much used for shingles and split boards, being remarkable for straightness of grain and 

 facility of sjilitting, often to very long lengths of even proportions. It is a valuable 

 tree, but now nearly all the region where it plentifully abounds has been run over by 

 the fires and it only exists as dead, blackened stumps, standing or prostrate, soon to be 

 lost to the country. This destruction of forests in Oregon by fire seems to have been re- 

 cent. The huge standing or prostrate dead trunks, now almost universal in the Coast 

 rano-e and over large areas of the Cascades, testify to the millions the country has lost 

 by this destructive element. — Elihu Hall, Athens, lil.

Rocks in a ravine, near Bethlehem, Pa., Rev. F. Wolle. 



Somewhat intermediate between Barbula ccKspitosa' and Didyinodoii cylindricus. 

 From the former it diflers in its longer stems, rather broader less carinate less undulate 

 and more fragile leaves, not uniformly recurved-pateut when moist, less pellucid at the 

 base, and with the costa neither pellucid when moist ncn- shining on the back when dry. 

 Very near the latter, but dittering in its more robust habit, shorter and broader leaves 

 rather less pellucid at the base and more or less contracted at the apex into a dagger- 

 shaped canaliculate point.
