He dealt also with the geology and mineralogy of New Brunswick and Prince Edward's Island.
The Gulf of St Lawrence with its much indented shores and the coast of Nova Scotia and New Brunswick supply endless harbours, the northern ones closed by ice in the winter, but the southern ones open all the year round; and on the Pacific British Columbia is deeply fringed with islands and fjords with well-sheltered harbours everywhere, in strong contrast with the unbroken shore of the United States to the south.
The " maritime provinces " of eastern Canada, including Nova Scotia, New Brunswick and Prince Edward Island, may be considered together; and to these provinces as politically bounded may be added, from a physical point of view, the analogous south-eastern part of Quebec - the entire area being designated the Acadian region.
The province of New Brunswick exhibits approximately parallel but subordinate ridges, with wide intervening areas of nearly flat Silurian and Carboniferous rocks.
In New Brunswick the Carboniferous rocks occupy a large area, but the coal seams so far developed are thin and unimportant.
