the valley of which it swung to Catamaran Brook and the Little South- 
west Miramichi. Its course beyond that it obscure, but the general 
parallelism, sustained by certain features of the smaller streams, would 
suggest a continuation of its course parallel with the present north shore 
of Miramichi Bay to French Cove and thence to the sea through Tabustin- 
tac Lagoon. 
12. The Tabustian Valley. Headed in the North Pole Branch (and 
probably in its Half Moon Lake branch, Note 99), followed the North 
Pole Branch across its big bend to near its mouth (Note 54) where its old 
course was in line with the Little Southwest below, thence along the 
Little Southwest, bending gently noith of its present post-glacial angle 
(Note 54), thence to opposite Little Sevogle and across to that stream, 
along it and across country to Green Brook, thence to Stymests Mill- 
stream and thence to Portage River and into the sea by the present course 
of the Tracadie (Note 94). 
13. The Tracadian Va'ley. Headed in the South Branch Sevogle and 
perhaps beyond in the West Branch of the Main South Branch of 
’Nepisiguit (as will be shown in a later note), and with another branch 
heading in the Lower North Branch (and perhaps beyond in the upper- 
most course of the present North Pole Branchy Note 99), and following 
Mullins Stream, across country south of the _ Square Forks to the 
Eskedelloc iand a part of Tabusintac, across the Tracadie near Head of 
Tide (Note 94), and by Little Tracadie to the sea near Green Point, (or 
possibly through South River, Pokemouche). 
14. The Pokemouchian Valley. Headed in the Main Northwest Mira- 
michi, receiving branches as shown on the map; and by the Main North- 
west, the East Branch Portage River, across to a basin near Meadow 
Brook on the Tracadie (Note 94) and along the Main Pokemouche to St. 
Simons Inlet and Shippegan Harbor to Bay Chaleur. 
15. The Caraquetian Va'.ley. Headed in the Tomogonops (and pos- 
sibly even in a part of the Nepisiguit near Indian Falls), swings to the 
south branch Portage River, thence to the source of the Tracadie and 
across to the Garaquet (Note 94) and thence to the sea. 
Such seem to me the most probable courses of these ancient 
valleys, though here again, while believing in the correctness of 
my explanation in general, I think it likely that considerable error 
may exist in details. Such an arrangement of ancient valleys 
would not only bring this whole series of rivers into homology 
with those in an identical geological formation south of the Mira- 
michi, but at the same time explains the reason for the re-entrant 
directions of the rivers flowing into the Minaqua River, a feature
