Kerr Lake Mine
 News Is Excellent.

ore discoveries at the Kerr Lake mine appeared to justify an advance in the price of the stock, but it oid not ma terialize. It was reported that in the course of trenching on the lake bottom the company had uncovered some re- markedly rich ore in a series of veins. These veins were identified as the Nc 10 vein system, which have been 50 profitable to the company at deeper levels.
 To date 300 feet of the No. 10 has been uncovered. averaging four to five inches of 1000 ounce ore. These veins have been traced up to the Grown Re- serve line. The extension in Grown Reserve ground is known as No. II system. The No. 10 vein has been stopped up to but not above the l40-foot level. It is at the l4O-foot level net work of rich stringers, which makes It possible to carry stope for thirty or even forty feet in width. Nowhere. however, on any of the levels is the No. 10 vein as rich as it it has been now discovered on the surface by strip ping. This is but repeating the ex- perieuce of the Kerr Lake ID regard to their East Main vein.
 During the year ending August 3l. 1913, stopiny on the No. 10 vein yield cd 363,8l4 ounces.
 A discovery has also been made in the diabass at No. 3 shaft at the second level in tho course of exploration. It was made in raise from long cross cut. The vein varies from one and a half to five inches. Where 1t is mar row it runs 4,200 ounces to the ton. At the sixth level, or a distance below the surface of about 300 feet, a vein of two inches of high-grade ore has been cut in the keewatin below the diabase. As this keewatin is at tine same hori- zon as the keewatin wherein the Beaver and the Temiskaming mines have mined most of their ore, this dis. covsry may be very interesting. Geol- ogists have always considered the chance of the Kerr Lake finding good ore in the keewatin under the diabase at No. shaft as good and this vein tends to confirm their prognostica. tions.
 With both pumps going, the mud is being drained out of Kerr Lake much more rapidly. To aid in dropping the level of the mud it has been determin- ed to put in a six.inch pipe for the pur- pose of hydrauicking, Experiment has shown that even when the mud is rendered more liquid by the admix- ture of water 1t can be pumped out at a much greater rate. There is now sufficient water pouring into the lake to permit of this process being carried on, as all the supply now comes from the rock house of the Kerr Lake. Without hydraulicking the mud can be lowered at the rate of 2,500 gallons a minute: with the installation of the hydraulicking operations. it is estimat- ed that it will be possible to increase this to 6,000 gallons minute, a very material difference.
 All the debris left on the dry slopes of Kerr Lake will be hydraulicked clean so that it will be possible to pros pect every inch of the surface. It is estimated that at the pumps where the the mud is deepest there is yet about thirty feet of the lime, but it rapidly grows more shallow toward the west end of the lake. Very curious is the collection of relics sucked to the grat- ing in front of the suction pipe by the big pumps. A big moose evidently was drowned in the lake at some time, and every bone has been recovered, so that if it were desired practically the complete skeleton could be reconstruct. cd. A number of crucifixes have also been found. It is supposed that these were lost by men and boys when they were bathing. The trenching opera tion on the Kerr Lake slopes have been so successful that it has been de- termined to clear off every foot of the surface as soon as possible. York Mining Age.
