[Gordon leaves] Grand Sere - Aug 15 - Tuesday, Crawled rock all day on the bare track. Collected a lot of material from two layers within two feet of each other. Mostly all bivalves. Many ostracods were noticed with a few mollusca and some trilobites. The rock is very hard and flinty and as the shells stand at all angles many fine specimens cannot be secured, yet the faunule is very interesting. Also some lightly colored material from a few feet higher. Gordon arrived during the morning and left for Gaspe Basin at about two in the afternoon. He will return to Campbellton on Thursday morning on the Lady Eileen. The main Sere of this Grand Sere faunule, I am inclined to be either the very highest Ordovician or clearly Cam-er dian, probably rather the latter. Many of the Ordovician species held over here but in general only species are of Camberan affinity.
