and only small quantities of gravels were obtained in the drifting opera-

along the south side of Slough creek above the mouth of Nelson creek were
also known to have produced considerable quantities of gold, and, as the
higher benches do not extend below the mouth of Nelson creek, it seemed
reasonable to suppose that they have been cut away and that the deep
ground in Slough creek opposite the mouth of Nelson creek has been enriched
by the gold from the benches. Probably nearly $500,000 in all was spent
in attempts at mining the deep gravels at Slough creek, with practically /
no returns. The following account of the mining operations is based on
information obtained from Mr. John Hopp, manager at the mine for several
years, from Mr. Laurent Muller, foreman, and from the reports of the
