It is curious to see the Bonaventure W. of Carle-
ton standing in edge. Accordingly it should be Devonian
comparable to Point St. Peter series. In character it looks
to me like true Bonaventure, but in structure it is De-
onian. What does appear to be the same strata that
are exposed at Gaeta Point, a thick basal conglomerate
folled[illegible] by the brick-red sandy “snail-shell” clays or
shale. If this is true the Devonian must be next lower,
but I saw none on the shore and inland I had no time
to explore, although the topography south of Carleton appears
to call for upended strata north under rocks since
there are drop-infall like ridges on the rising elevated
beaches earlier referred to.
The Bonaventure cnyl. W. of Carleton and at Gaeta
Point has in certain parts a calcite filling just as found
in the Pointe Peter series. Has this a correlation value?
I do not remember ever seeing it in the true Bonaventure.
The Bonaventure cnyl. W. of Carleton is in the high
basal strata composed of small pebbles under one inch,
but in the older agglutination border beds are commonly
from 2"-4", while many range up to 8". There is a great
variety of rocks but the light blue or dark malle of mine
than 5-10% of the whole, and including the Percé pink
and fellows is does not exceed 15%. All are sub-angular.
