A COLLECTION OF INTER-GLACIAL WOOD. 529 
5°. rom buried forest, Mur glacier. 
Consists of a piece of bark 18™ long, 11°" wide and about 
4 thick. It is not the least changed by water action and pre- 
sents the same bright reddish appearance as a piece from a living 
tree. It is also accompanied by a number of fragments of wood 
that are very light, yet appear very little changed. The larger 
piece is riddled by a number of worm holes, showing that the 
wood had been exposed for a time to the attack of insect larve, 
before being entombed. 
6. A piece of stump on east side of Mur Inlet, near Camp Muir ; 
uncovered only at very low tide. 
A thin chip, evidently cut from a large stump, having a thin 
bark still closely attached to it. It has been very little changed 
by the action of the elements. 
A single specimen from under the eastern moraine, obtained by 
Miss E. R. Scidmore. 
This represents a branch or stem 30°" long and about 5°™ in 
diameter. A thin bright-colored bark still adhered to most of 
the piece, while the wood is very little changed, being bright 
colored and fresh. 
The living woods mentioned above were accompanied by 
only three kinds of leaves, which have been identified as follows : 
Picea Sitchensis, Carr., Tsuga Mertensiana, Carr., and Chamecyparis 
Nutkensis, Spach. 
PICEA SITCHENSIS, CARR. 
The tide-land spruce is a tree of very large size, found from 
Alaska south to Mendocino county, California, not extending more 
than fifty miles from the coast. The wood is light, soft, straight- 
grained, compact and satiny. The bands of summer cells are 
narrow and inconspicuous, and the resin passages are few and 
obscure. The medullary rays are numerous and prominent. 
The color of the wood is light-brown tinged with red, but the 
sap-wood is nearly white.
