show that “epidotic, chloritic and serpentinous rocks, with crys- 
talline limestones and magnetites, are as characteristic of Upper 
those of Eastern Canada and the New England States.” He ob- 
serves that Sir William Logan has been carrying forward extended 
and thorough investigations in Canada on this point, connected 
with a study of the true stratigraphical relations of the rocks, and 
that he will give a full report as soon as “the necessary examina- 
tions have os completed.” 
The Report also states that boring for water and coal in th 
Northwest Terri itory with a diamond-pointed drill was andoreaki 
the past year, but that there was not time after receiving the ap- 
paratus for obtaining any important results. The boring will be 
resumed this season. 
In his Report on the Northwest Territory, Mr. Selwyn states 
that, going we ees ome Fort ries (or We the capital 
oN, 
of Manitoba, lat. long. 96° 50’ W., only drift—sand, 
clay and pee Bets seen along their course for a distance of 8854 
m The first terrace plain in that direction has an stoic 
average elevation of 1600 feet.” A third prairie level commences 
at the Thickwood — 20 miles west of Carleton; it is 1900 to 
farther west than the Tongitade of Fort Pitt. Sand is the material 
of the deposits, and it is mostly unstratified, becoming imperfectly 
stratified and calcareous to the westward. At Fort Elli ice, the 
valley of the Assiniboine (as stated by Dr. Hector) is 240 feet 
deep: the upper 1” feet consist of this drift deposit, and the rest 
of Cretaceous be 
he watershed eekwek the Quw’ Apelle to the southwest and the 
Saskatchewan and Assiniboine to the northwest, is mostly a great 
salt plain, with many pit-holes and some large salt lakes. 
n the North Saskatchewan River, between doprenenner and 
Rocky Mountain House (138 mi les), several horizontal coal beds 
were observed, one of them 18 to 20 feet thick, aid tavsratie for

Qu’ Appelle valley. The age of the latter is pronounced probably 
Tertiary ; of the former, it is stated to be yet uncertain. The 
plants in the two are the same. The coal-field is stated to extend 
at least to the Athabasca River on the north, and Red Deer River 
on the south, and to have an area of 25,000 square miles. pre 
ses of the coals by Dr. B. J. Harrington are given on pages 63, 64
