limestone wall Is not so well defined. as the ore fades into the lime from the main bodies. The ore occurs in lenses and irregular masses. with garnet, epidote, feldspar, and altered lime- stone. It contains from to , per cent copper and sl.50 to g gold per ton. generally in ehalcopyrite. Streaks and Jumps oi moly adenite are observed in the garnet and limestone. It does not ION appear to be of commercial value. Tie .. . bodies are opened by g series oi aCi.s or levels, most of which cut the ore st the surface. The vertical distance between the highest and Invest of these levels is 500 fl. The several higher levels are connected by chutes with the main working levels, which connect with the tram way. h all there is said to be about l. O00 fl. of workings. Faces of ore and stoped-out chambers show ore-lenseS 50 10 50 it. wide. The ore is hard, snd drills used in it dull rapidly; it stands well and requires little timbering. The Temple air electric drills are in use. but a Sullivan compressor and air.drills have been ordered to sup plement them. The compressor will be installed at the mine and will be electrically driven. The mineral zone, in its strike southeast, cuts the sum- nit of the mountain, which rises 2000 ft. higher than the mine workings. Following the contract northwest erly 200O it. or more from the hase ot operations the belt is seen to contain bodies of magnetic with some copper. Eight of the company's claims on this part of the mineral zone have been leased for five years to the Tyee Cop per company. R. G. Mellin has been sent there with diamond drlls to inspect the ground.
 The Nit. Andrew mine is situated on the south side of kasaan peninsula. It belongs to the Mt. Andrew Iron and Copper company having headquarters at Seattle. Sam Lichtenstadter is manager with W. c. Freeburn as sup erintendent. The property was form erly under lease to the Britannia com pany but is now being operated by the owners. Since November 1906 P. 600 tons of ore have been shipped and the company is now shipping at the rate of 1j00 tons pc month. The ore Is sulphide. assaying four and half per cent copper forty-two per cent iron and sl25 per ton in gold ana silFer. There are ore bins and a wharf on Kasaan bay. and from this place a 3050 foot Ribiet aerial tram way extends up to the mine. There are also two air compressors at the beach from which pipe conveys air 10 the mine. There is strong out crop of copper-iron ore OF the surface along contact of limestone and syenite the ore being in irregular bodies.
 ! main working level has been driven from the side of the mountain. cutting 100 feet off below the main croppings: :: and from this level numerous drifts have been driven to open the ore bod ies within large area, the level and drifts aggregating 1000 feet.
 At various places on the drifts raises have been made to the surface, con- necting with open pits. The ore is blasted in these pits, or gloryholes, and sent down through chutes to the drifts, thence conveyed in ore-cars to the bins at the tramway terminal. There are 10 of these glory holes, not all of which are being actively worked as present. Sinking is in progress on the main level, where a compressed air hoist is being installed. The Mamie and 5teyenstown mines are situated a short distance north of the Mt. Andrew but these have been inactive for some time.
 The IL Mining Co. has shipping
 mine farther west on Kasaan bay. r. C. Strong. C. H. Black and John C. Barber are the principal interested parties, Mr. Barber is in direct charge. The ore is chsIcopyrite in limestone. X bout 4OO0 tons have been shipped since last November, a-saying 10 per cent copper at the shelter. l. is stated, also, .hst ore with 10 per cent copper carries fi gold and l1l oz. silver per
