mation to the southeast. While attending an excursion at Blue- 
berry Point a few obscure fossils were found in the Chazy shales 
- which are exposed on the shore of the lake ; and at Hull near the 
Cement Works the Trenton limestone was studied and some fos- 
sils collected. The erratics and clay deposits of this place present 
an interesting field for study. 
Several of the members attending the general excursion to 
Chelsea joined the geological party and had a good opportunity 
of studying the garnetiferous gneiss and other Archzean rocks 
exposed in the railway cuttings, also the boulder clay, Leda clay 
and Saxicava sand and the marine shells found in the two upper- 
most formations. About two miles west of King’s Mountain 
Mr. Joseph Keele discovered a pot-hole in the gneiss near the 
edge of the cliff which faces the south. — This cliff is at about the 
same height as King’s Mountain and is therefore 1100 feet or 
more above sea level. The pot-hole is perfect in form and is 
eighteen inches in diameter and about the same depth. How this 
was formed at that height is a very interesting problem. A kettle 
hole near tlie east end of Meach’s Lake has also been noted. It 
can be easily found as a hotel has been erected on its southern 
rim. This is no doubt an old valley of erosicn. 
BESSERERS, ONT. 
On the 26th of October, a party of ten, in conjunction with 
the Geological Branch of the Club visited Besserers Grove, down 
the Ottawa river some eight miles, and searched the shore for 
concretions containing fossil organic remains. A fire was built 
and the concretions collected were heated and opened, some of 
which revealed the well-known and much-prized fish, Wallotus vil- 
losus, Cuvier, the modern capelin of the Lower St. Lawrence. 
Fragments of stems of plants, of leaves of deciduous trees, of 
algae or sea-weeds, of water-plants, were also obtained, besides a 
number of shells, Sexzcava rugosa, Linnzus, and Macoma Balthica, 
Linneus, being the most prevalent. There was an unusually 
large number of concretions visible on the clay shores of the Ot- 
tawa river along that portion of the south bank between the Grove 
and the mouth of Green’s Creek. These concretions occur at 
different horizons in the clay formation skirting the south shore 
of the Ottawa at this point and four distinct layers containing
