48

inches of white material on top, the base lying on dark grey mud. The writer found the base at 54 inches toward the other end of the deposit. The amount of commercial magnesite is estimated at 4,570 tons.

Area No. 4 covers about 1,500 square yards and the upper layer of puré material has an average thickness of 16°5 inches. Below this in one hole there is 3 feet 6 inches of yellowish hydromagnesite becoming harder and carrying more grit toward the base; the same earth but with more grit and brown colour continued to 8 feet 6 inches from the surface. Under this was 6 inches of reddish earth with freshwater shells and carbonaceous remains of roots and seeds. At the very base a plastic green clay was pence’ to a depth of 15 inches. There are 680 tons of the upper layer

ere.

Area No. 5 covers 8,950 square yards. Three holes in the east half showed fairly pure material from the surface down to 60, 48, and 37 inches, respectively, with black specks showing toward the surface. In one hole a ‘band of yellowish material separated a top layer of white from a 2-foot band of white below. Below to the bottom of the deposit at 7 feet 3 mches, was impure brownish earth. In another of the three holes the material from the base of the fairly pure hydromagnesite became gradually dirtier down to the bottom of the deposit at 7 feet G6 inches. In the third bore- hole, with €0 inches of white material, the underlying earths gradually changed in colour from grey to pink and the bottom of the deposit was at 8 feet 10 inches. The white and pink earths overlay a green clay with freshwater shells. In the west end of this patch a hole showed grey-white material with black specks to 54 inches. From there it was white, but with much silica to 6 feet. Below this there was clayey material. The amount of the upper white material is calculated to be 13,232 tons.

The total quantity of commercial magnesite at Watson lake is in round numbers 23,000 tons. The quality of the upper white layer is expressed in analyses 4 and 5, Table II, and analysis No. 8, Table III. It is uniformly low in lime, but the silica content varies as it does at Meadow lake, and is high in places. |

The Watson Lake deposits are about one mile from the railway grade and below it in elevation. The shipping point would te about 225 miles from Squamish.

Riske Creek.

The area on lot 178, Riske creek, owned by 8. M. Becher, Riske Creek, covers 10,000 square yards. One auger hole showed white to cream-tinted hydromagnesite to a depth of 33 inches; from there down to 4 feet 2 inches the earth became gradually browner. At that depth there was brown clay. The estimated tonnage of the white is 6,900 tons, but this is based on only one opening, and may be much less. An analysis of material from the upper 2 feet in the auger hole indicates magnesite of very good quality, -Table II, analysis 6. |

The deposit on lot 1188, owned by A. E. Carew-Gibson of Vancouver, covers 26,000 square yards, of which 7,775 square yards is covered by white hydromagnesite standing slightly higher than the remainder. Two holes in the pure earth showed white material to depths of 2 and 3 feet, respectively. Below this the earth became browner and dirtier looking. The holes were not bored below 3 feet 7 inches. Analyses made from the material from one of the holes, 0 to 26 inches from the surface, is given in
