The quartzite of Montmorency fall is called gneiss, and the lime- 
stone of Montmorency and Beauport is referred to the carbonifer- 
ous limestone of English geologists, 
1829 — Baddeley (F. E.). — On the geognosy of a part of the Saguenay coun- 
try (Trans. Lit. and Hist. Soc. Quebec , vol. 1, p. 79). With a 
sketch geological map from Cape Rouge and Quebec to Lake St. 
John. The limestone of Montmorency is referred, with doubt, to

1829 — Green (William). — Notes on the country in the neighborhood of the

Beauport limestone is referred to the Trenton Limestone ; the sand- 
stone and conglomerate, fifteen to twenty feet thick, directly below

ceder pour faire une exploration geologique de la province,” is 
dated, 6 Dec. 1842. Atp. 20 of this preliminary report, the author 
says that he does not know the exact place in the stratigraphic 
scale of the folded rocks at Pointe-Levis, but he inclines to regard 
them as below the horizontal strata of the St. Lawrence limestone 
(that is to say the limestone of Beauport and Montmorency) . But 
acting under the influence of advices received, shortly after, from 
1 The order is chronological even in each year, when several papers were 
issued during the same year.
