the quarrymen employed, it is possible not a few may have 
escaped observation. My collection there was limited to a few 
which had been acquired previously. It may be noticed, as re- 
gards this particular quarry, the underlying shales were found 
to be quite as barren of these organisms as the Niagara limestones 
or the chert beds themselves. 
THE CITY QUARRIES. 
The writer was glad to find that the corporation intended to 
open another quarry near the Mountain View Hotel, when they 
ceased work on the Webber property. This new quarry, close 
to the Strongman road, proved very disappointing. When 
stripped of the surface soil, there was not the slightest appear- 
ance of glacial clay—nothing but decayed or badly weathered 
chert beneath it, which certainly was unfavorable for fossil 
preservation. There are places in the quarry where the beds 
have not suffered much from water-soakage, but the complete 
absence of Bryozoon shells, ete., there, also seems difficult to 
explanation. One may notice an unusual number of deposits 
called ‘‘Dendrites.’’ Perhaps the manganese oxide may account 
for this utter barrenness apparent. A few Graptolites were 
found in part of the Webbér quarry not handed over to the cor- 
poration, but it produced much less than what was expected. 
The Hancock quarry was reopened recently, I understand, 
to obtain road metal from the chert beds for the county. On 
looking over a portion of the material excavated, I was greatly 
pleased to discover a rare Cephalopod for the Niagara rocks—a 
Gomphoceras. It may be the one already named by the late 
Dr. James Hall, which I have not seen figured. It is not unlike 
one found in still older rocks in Ohio—Gomphoceras ‘‘eos’’—the 
class is not so uncommon in later Palaeozoic times. The specimen 
is an interesting addition to local organic remains. Very recently, 
also, my old friend and fellow-worker, Mr. Nichol, produced for 
acceptance a ‘‘Dendrograptus’’ (new to me) from a decayed 
upper chert bed, which the centre fortunately preserved unweath- 
ered, almost miracuously. Still later, from a lower chert bed,
