The fetid limestone which overlies micaceous schist at St. Paul’s 
Bay, we have conjectured to be a transition rock, On Lake St. 
John, secondary limestone (of the carboniforeus order ?) forms, 
with clay-slate, the southwest portion of the shore of the lake, 
from Pointe Blue to within three miles of the Post of Me- 
tabitshuan.* At page we have considered this to be a 
secondary rock in the limited sense of the Wernerians, and were 
surprised in consequence, to find it alternating with clay- 
slate. This opinion is now no longer entertained, as the very 
circumstance of the existance of such an alternation, together 
with its characterestic imbedded fossils, prove the rock to 
belong to the transition class or earliest of the secondary class 
of MacCulloch. It is thought that no secondary limestone 
(in the limited sense) was met with, without the horizontal 
rock at Mal-Bay be of that class, which is not improbable. 
Information indeed has just been received, that a large depo- 
sit of bituminous coal, in association with limestone, has been 
discovered in the parish of St. Urbain, in rear of St. Paul’s 
Bay, but we do not know what degree of credit to attach to 
the report. Believing the latest rocks in that neighbourhood, 
to be of the transition class, and consequently below the coal 
fields, we think it not likely that any considerable quantity of

* Sir Alexander Mec Kenzie states that the narrowest part of Lake Winipic 
is not more than two mi'es broad, at which place the west side is faced with 
rocks of nearly borizootal limestone about thirty feet high, while the east side 
is more elevated, and is composed of a dark grey granite. Immediately af- 
terwards, he observes, that all the great lakes of the country are to be tound 
between these extensive ranges of granite and limestone. Keating appears 
to think it probable that the excavation of this lake was occasioned by the 
easier decomposition of the strata at the junction of the two formations. It 
is certainly deserving of attention thatthe Lakes, Slave, Bear, Arthabasca, 
Winipic, Superior, Huron, Ontario, St. John and Mistassiny, have large 
deposits of secondary timestone on their shores, whilst some portion of these 
lakes in either granitic, syenitic or trappose. The limestone of Lake St. 
John must be either isolated or connected with the same formation at St, 
Pauls or Murray Bay. A considerable degree of probability is given to the 
latier conjecture, by the cximence of @ fine level country at the back of these 
setulements.
