No shipments have yet been made from Squak Creek, Raging River, or Snoqualmie Mountain, but active developing work has been in progress since September last at the Gilman Mines (forty miles from Seattle), and shipping will begin shortly. A switch of only 600 yards in length is required from the main line of railway to reach the outcrop of the coal, and there is every natural advantage for mining. [Sidenote: Seattle Coal and Iron Company.] [Sidenote: Seven seams.] [Sidenote: Details.] The Seattle Coal and Iron Company own this property, which consists of 1,300 acres underlaid by seven coal seams, five of which will be mined ultimately, three in the beginning. I was able to examine three seams which will be mined at first, and give the following details. Top Seam, No. 4, descending: Roof, rich Bituminous Black Slate, containing streaks of-- FT. INS.

[Sidenote: Good coal.] This is a good seam of coal, five feet six inches of which can be depended on for shipping. The coal is dull-black in color, and easily mined. The bottom is soft sandstone. Overlying the roof-slate, is sandstone. The seam here is said to be one foot thicker than it is at Newcastle. [Sidenote: Another good coal seam.] Seam No. 2 has been uncovered by the diggings on the railroad, and happens to be at an [Illustration: COAL-BUNKERS OF THE SEATTLE, LAKE SHORE AND EASTERN RAILWAY, ON SEATTLE HARBOR.] unfortunate place for showing the coal. A stump, partly silicified, with part of its bark lignified, had been taken out of the coal bed, and on each side of it was a tapering band of "Nigger-head," tapering from eight inches at the stump to nothing at the distance of five feet six inches from the stump. Selecting an average place, I got the following section, descending: Good roof of Argilaceous Sandstone. FT. INS.
