UNITED STATES, CANADA AND MEXICO 265
and
at Parrsborough, N. S. In the Queen Charlotte Islands, B. C, they occur
abundantly at some localities, being derived from the miocene-tertiary
rock.
Beautiful
moss agates are found at Two Islands, CumberÂland County, and near Cape
Split, Partridge Island, also at Scott's Bay, Kings County, N. S.,
where they are exceptionally fine. Chrysoprase of fair color has been
found in the Hudson's Bay district, on Belanger's Island.
Silicified woods are found in the northwest Territories and in British Columbia.
Jasper
conglomerate exists in mountain masses, along with the quartzite masses
of the Huronian series, for miles in the country north of the Bruce
Mines, on Lake Superior north of Goular's Bay, on the St. Mary's River
about four miles west of Campment d'Ours, on the east shore of Lake
George, and on Lake Huron, Ont. It is a rock consisting of a matrix of
white quartzite, in which are pebbles, often several inches across, of
a rich red, yellow, green, or black jasper, and smoky or other colored
chalcedony, which form a remarkably striking contrast with the pure
white matrix. It is susceptible of a high polish, and has been made
into a great variety of ornamental objects. Some very beautiful mosaics
have been produced by using the rock and included pebbles. It occurs in
thick bands extending for miles, and in large boulders, scattered along
the shores of the lakes and rivers. Within half a mile of the northern
extremity of Goular's Bay, Ont., is a ridge containing several
varieties. Large quantities of rich, red jasper are found in Hull, Que.
Yellow and red occur at Handley Mountains, Annapolis, Pictou,
Gulliver's Hope, Blomidon, N. S. ; at Belleisle Bay, Kings County,
Grand Manan, Darling's Lake, and Hampton, near the mouth of the
Washdemoak River; at Red Head and at the Tobique River, Victoria
County, N. B.; at Woodworth's Cove, west of Scott's Bay, and all along
the shore of the Bay of Fundy from Sandy Cove, N. S. Near the head of
St. Mary's Bay lie large blocks of red, yellow, and yellowish-red
jasper, often banded, but generally impure.
Heliotrope (bloodstone) in good specimens is of rare occurÂrence in the North Mountain, Bay of Fundy, N. S.
