The northbound wagon road along the western side of the Port Daniel 
barrachois is also on “Ordovician” strata in its terminal half mile or more 
beside Middle river, and here soft, smooth, blue-green shales with some 
thin sandstones are exposed. These strata looked as if they should have 
fossils, and several attempts were made to get them, but none was found. 
It was less than a mile farther up the Middle branch of Port Daniel river 
that Logan, in 1843, found graptolites of seemingly unmistakable Ordo- 
vician age. 
The most easterly area of Ordovician strata seen by the writers was 
along the banks of the North or East branch of Port Daniel river beyond 
the tidewaters of the barrachois. Here the well-exposed “Ordovician” 
consists largely of greenish sandstones, and more than one mile up the 
tributary known locally as Ruieseau du Lac k l'Appelle, crinoid columnals 
and poor bivalves were seen in sandstones that resemble the Upper 
Ordovician. In the Pleistocene wash near this place were found much 
decomposed, limy sandstones having an abundance of Dalmanella 
r ogata; these strata, therefore, appear to be well up in the Ordovician. 
Since the Ordovician is well developed in Perc4 region, where the senior 
author collected Richmond fossils, the chances are good that the graptolite 
beds of Port Daniel river are also of Upper Ordovician. 
No Ordovician is seen between the Silurian and the Macquereau east 
of Gascons, and according to Elis’ map none appears until 3 miles northwest 
of An se- Ala- V ieille , following along the contact of these two series of 
strata. 
MIDDLE SILURIAN OR CHALEUR (NIAGARAN) SERIES 
The very thick Silurian development about Gascons and Port Daniel, 
to Indian point, a distance in a straight line of 9 miles along the north 
shore of Chaleur bay, Gaspe peninsula, was first reported on by Sir William 
Logan in 1846. This information was later incorporated in Logan’s 
“Geology of Canada, 1863,” pages 442-445. It is now seen that Logan 
was fortunate in his reconnaissance trip in coming upon this well-exposed 
seashore section from the east, and tracing it westward into higher strata. 
His determined section, which is restated below, extends from Anse-Ala- 
Vieille (a name now forgotten along this coast) to Anse-Ala-Barbe. Far- 
ther west one learns of no new formations until cape l’Enfer is reached, 
but here the closed syncline, mainly of limestones, is so repeatedly faulted 
as to give no clear idea of the detailed succession of the strata, nor of the 
actual thickness, which is far greater than that of the cape. To get this 
information, one must go farther west and study the fine cliffs from West 
point westward to Indian point. Logan made out a thickness of 3,340 
feet, but the work done by the writers determines the thickness to be more 
than 5,000 feet. This discrepancy is due to the very thick, upper limestone 
series, which at West point is three times thicker than at the Gros Morbe, 
where about 500 feet of the lower limestones are still present. 
Logan says that the vertical strata of the Macquereau series extend 
along the coast toward An se- Ala- V ieille , where they are overlain by the 
inclined strata of the Silurian limestones, which, in their turn,
