Lake Brook heads so close to Green Brook, and there is so little 
rise between, that it would be a very easy matter now to turn 
the South Branch waters out through the Shiktehawk, and it 
is possible that in pre-g‘lacial times a part of these South Branch 
waters did thus empty. Elliot Brook is evidently the real 
morphological head of this branch, as it shown by the fact that 
it is continuous in direction with the valley of the united streams 
below it. Furthermore, the directions of the heads of the 
M unquart and the Shiktehawk are such as to imply that formerly 
they also emptied into Elliot Brook, and I am told that the 
country is low in places where such connections would be. 
Finally the directions of streams suggest a possible old outlet 
of this Branch into the Nashwaak, and perhaps across by Nash- 
waak Lake to the Northwest Branch of Napudogan. But this 
is merely a speculation. 
The North "Branch .* 
The extreme source of this Branch, which is the extreme 
source of the Main Southwest Miramichi, I failed, despite deter- 
mined effort, to reach ; but I am told that it heads in large springs 
two miles from River de Chute, as shown on the map, flows 
through an open barren, receives a branch from an elevated 
mass of “ black peaks," and has a fall of eight feet. Finally, as 
* This Branch figures somewhat prominently in the history of railroad 
building in New Brunswick. It was first surveyed for seven miles from the Forks 
by Jacob Allen in 1831, and thence to the head of the principal deadwater by 
H. M. G. Garden in 1837 ; and their maps are the foundation of the subsequent 
cartography. (MS. in the Crown Land Office at Fredericton). In 1844 the valley 
was surveyed by Lieutenants Simmons and Wood, of the Royal Engineers, in 
connection with a proposed military road from Halifax to Quebec, but no reports 
or maps of theirs are known to me, although there is some reference to the survey 
in Alexander’s L’Acaclie (1849, II, 81, 201, 237). In 1846 it was again explored 
in connection with the proposed first Intercolonial Railway, as mentioned in Major 
Robinson’s paper on the Quebec and Halifax Railway in Papers on Subjects con- 
nected with the duties of the Corps of Royal Engineers (II, 1852, 47, 51, 52) ; 
but reports and maps of this survey are likewise unknown to me. It was again 
surveyed in 1864 for a central route for the present Intercolonial Railway, as 
mentioned in Flemings Report on the Intercolonial Exploratory Survey (Edition 
of 1868, 17, 24), and in his “History of the Intercolonial Railway.” (Montreal, 
1876). Finally in the winter of 1904-1905, it was again explored in the search 
for the best route for the new Transcontinental Railway, and its relations with
