mately, an inch in diameter, and several smaller fragments, 
which all appear to have come from the same trunk. The large 
piece is slightly worn on one side, but the rest of the specimen 
appears freshly broken, as do the smaller pieces. This wood 
is very light and is the most metamorphosed of any of the 
specimens. It can be easily rubbed to powder between the 
thumb and fingers, appearing in this respect like wood affected 
with what is known as ‘‘dry-rot.” There is no evidence, how- 
ever, of the presence of attacking fungi, and its softness is 
doubtless due to its prolonged masceration. It is very dark 
brown, almost black, in color. 
As already stated this specimen has been badly changed, so 
much in fact that it has been impossible to identify it with satis- 
faction. It is the only one left undetermined. 
2. From the buried forest, Mur glacier. 
A piece evidently cut from near the root, which is 20™ long 
and about 40°" in diameter. It is without bark, yet is only 
slightly abraded. One end is much split and “broomed”’ as 
though by action of water. The wood is very hard, and is but 
little changed. 
3. Found on surface of gravel deposits south of Camp Mur, very 
abundant. 
A segment cut from a trunk or branch 8™ in diameter. It is 
without bark and bears evidence of having been exposed. The 
wood is compact and shows little if any change from the normal 
condition. } 
4. From buried forest, Mur glacier. 
A number of small water-worn branches, the largest being 
less than 2™ in diameter. The woody structure is very little 
changed, being still compact and bright where freshly broken. 
5. Lrom buried forest, Mur glacier. 
This consists of two pieces of bark 20°" long and 10™ wide, 
without trace of wood. This bark, which is less than 1™ in 
thickness, is but very little abraded and is indistinguishable 
from recent bark.
