to it, and this view seems to gain strength from the observations of 
Sir William Dawson, who recorded in a footnote to his paper published 
in 1893,* that while the latter was in press, he received a specimen 
of a flattened, cylindrical stem of about an inch in diameter. He 
determined the structure to be coniferous, and expressed the opinion 
that it probably represented the wood of Ginkgo pusilla.

This species has been known heretofore, only through its foliage 
and fruit, but in the material from the Queen Charlotte Islands there 
were two specimens of calcified wood which proved beyond all doubt 
to be identical with one another and with the genus Sequoia. One 
represented a small branch devoid of bark. It was 6-5 em. long and 
18 mm. wide in its greatest diameter. It had been flattened some- 
what by compression so as to present an elliptical section. The struc- 
ture proved on the whole, to be in a very excellent state of preservation, 
although regional areas of more or less extended: decay were to be 
observed. The larger and more important specimen was 12-5 cm. 
long and compressed into a narrowly elliptical form 7 X 3-7 em. 
The remains of barnacles indicated immersion in salt water. There 
was no external evidence of a cortex, but the end exhibited a some- 
what definite indication of what seemed to be separate pith, wood 
and bark. A complete transverse section served to somewhat modify 
the opinion formed on the basis of the external features. Decay was 
found to have been carried so far as to involve the greater portion 
of the structure. What had been taken for the pith proved to be a 
region of the wood structure only partially altered by decay. External 
to this the broad zone supposed to be the wood, was found to be an 
area of advanced decay which had involved the woody tissue, and 
nearly obliterated all traces of former structure, so that the resulting 
modifications from decay and pressure had developed an appearance 
which, externally, simulated wood with its medullary rays. Externally
