in one case than in the other, and it is therefore admissible 
to consider that my reference of Celluloxylon primevum to 
Nematophyton crassum was not only correct [in a former 
paper, Trans. Roy. Soc. Canada, Vol. VII., Sec. IV., 1889, 
p. 29], but that it receives striking confirmation from these 
specimens.” * 
Five years after the write*’s visit to this locality it was 
studied by Dr. Heinrich Ries who gave the following account 
in his “Report on the Geology of Orange county: “About 
one and one-half miles northwest of Monroe, on the south- 
west base of the mountain [Skunnemunk], and 300 feet lower 
than the Davidson quarries, are several small quarries on the 
tand of O. H. Cooley. The rock is a thin bedded sandstone, 
with shaly layers, which have been polished to a high degrée 
by shearing. Concretions occur in the shaly layers and 
also in the coarse sandstone ledge to the northeast of Cooley’s 
largest opening. The shales contain abundant remains of 
plants, commonest among which is Psilophyton. Several 
of the others were submitted to Prof. Knowlton, but they 
were too fragmentary for identification. Prosser notes the 
finding of Celluloxylon primevum, as identified by Knowl- 
ton. The specimen found ty Prosser represented the end 
of a stem protruding from the sandstones of Cooley’s quarry. 
At the time of the writer’s visit in September, 1895, Mr. Cool- 
ey had uncovered the specimen to a length of twenty-nine 
feet. The ‘fossil tree’ has a diameter of fourteen inches at the 
upper end and eight inches at the lower end. To this point 
it dips about thirty degrees along the bedding; the stem 
then makes a sharp turn, and can be seen extending downward 
several feet more at an angle of about seventy degrees.’’+ 
Dr. Ries has written me as follows regarding this subject: 
“I did not hear of any other specimens of Celluloxylon in 
neighboring quarries. At the time of my visit there were 
several large pieces at the opening which Cooley said he 
had removed from the end of the trunk. I believe these were 
obtained by Dr. Hollick for Coiumbia. I had an idea that the 
pieces which Mr. Nevius got had been removed. from the
