Canada and the adjacent regions, including the other British provin- 
ces, and parts of the United States,” eight sheets, each 24x20^- 
inches ; scale 25 miles to one inch, 1886. Although dated 1863, 1865 
and 1866, the complete work was not issued and distributed until the 
spring of 1867. In taking 1865 for the year of publication of the 
work, it is a fair average of the dates inscribed on its three different 
parts. The bulky volume in 8vo, contains observations on the vicin- 
ity of Quebec in chapters ix, x, and xi, frompp. 196-296; in chap, 
xxii, pp. 861-864. On both the geological maps, the vicinity of Que- 
bec is colored as Chazy and Calciferous formations, with a band of 
Hudson river groups, extending from the rear of the citadel to 
Montmorency. The author described a great fault or break, made 
by “an overturn anticlinal fold with a crack and a great dislocation 
running along the summit, passing just north of the fortress.”
