104 JOURNAL AND PROCEEDINGS. 
ceeded in getting some few hundred yards up stream, when I 
arrived at a place which was utterly impassable. I had reluctantly 
to return to the station. Here I ascertained the entire party had 
gone off a little while before in the direction of the Ravine. I 
failed to overtake them, and as I had previously ascertained that all 
the ladies had taken to botanizing or ‘‘butterfly-hunting,” I 
naturally concluded I would see very little more of our recreant sec- 
tion on that occasion, so I turned my attention to the (Quarries, 
hoping to intercept a stray member on his return, and 
induce him to assist in conveying to the railway station 
some of the best specimens obtainable. Unfortunately the majority of 
the excursionists passed over to the other side of the stream and re- 
turned by another way, and a few, detained to witness the remark- 
able preservation of some of the Fucoids, could scarcely be ex- 
pected to volunteer their removal when already in possession of 
baskets of provisions, ferns and plant cases, with various other 
things. 
A paper onthe Silurian Rocks of Grimsby must necessarily be 
incomplete owing to the difficulty of a proper examination. ‘There is 
a fair exposure in descending order of the Niagara lower shales, 
the old Clinton (Niagara limestone), the Clinton upper green and 
Iron bands, in the quarries. —The remainder are concealed measures 
except in the brook bed. The shales, unlike ours here, are very fossil- 
iferous, and interspersed through the softer clays are thin limestone 
layers containing many Brachiopods, Coral and Bryozorus. On one 
of the slabs before us you may notice the beautiful little Lzchwaldia 
of the late Professor Billings. It occurs also in our local chert, but 
rarely ; the coarsely ribbed Spirifira Sulcatus is also common to 
both. No collector in the neighborhood of Hamilton has been 
more successful in obtaining such a varied assortment of organic 
remains from what we call in the old country the ‘‘ Wenlock 
series ” than my indefatigable friend of the olden days, Mr. J. Pettitt, 
but unfortunately few were figured or described at the time of the 
Original discovery. The extensive collection of Cambrian and lower 
Silurian forms in the Museum of the Canadian Geological Survey 
Office were almost unknown outside this continent, and I am quite 
satisfied now that Professor Billings acted wisely in confining his atten- 
tion chiefly to the study of our oldest organic remains. His train- 
ing as a lawyer was not time wasted, since it taught him to pursue
