existence was looked upon as almost impossible? On this account, 
the writer hesitates to assert the Webber Quarry is less fossiliferous 
than the other which had previously been opened by the City Cor- 
poration. ‘The few graptolites discovered there during the last two 
collecting seasons were generally in good preservation and differ from 
any found in the other quarries in several instances. Some were 
discovered at the base of the chert, and most probably may be new 
to science on this continent. 
In the Webber quarry the men employed by the corporation 
have worked back the Macadamizing chert very nearly to the level, 
where rock material was removed formerly from the adjoining quarry, 
before it was worked out, and which I found contained large num- 
bers of graptolites, differing from all found in well-known layers 
beneath. ‘There was something in the glaciated bed—an irregular 
thickness in places—which reminded me of the abandoned quarry, 
and although many years have past I perfectly recollected everything 
relating to the point of the old beds where I had discovered so many 
specimens. ‘The general appearance at present was such as led me 
to believe we were approaching the locality of a graptolite colony, 
and when some few specimens were recently obtained it tended to 
confirm the opinion. However, later research induces me to fear 
these may have been merely outliers from the older one. This is a 
matter which may soon be settled if quarrying is kept on a little 
longer. Indeed, there is every appearance of that, for the writer 
noticed men removing the overlying soil, and so far back that we 
may be afforded an opportunity of examining ten or twelve yards of 
rocks which had not been laid bare or examined in the other quar- 
ries. At the rock cutting on the Grand Trunk Railway I was only 
able to examine a few feet of the glaciated chert formerly, when I 
discovered the sponges and sponge sections 27 s7zu. 
On returning to-day, October 28th, from an unsuccessful hunt 
for glaciated flint flake fossils, I paid a visit to the quarries, which I 
generally examine every day, wet or dry, when the Superintendent 
employed by the city, Mr. Nichol, informed me he had a little time 
before my arrival obtained a fine graptolite from a bed in the blue ~ 
building Niagaras, lower down than he had ever seen one before. 
On pointing out the place and position it was clearly shown that
