The incline from the oldworks was run on the vein with an average pitch of 21 degrees, and hasbeen stoped for five hundred and eighty feet in length. The tunnel wasdriven in from the surface five hundred feet, cutting the vein at abouttwo hundred and ninety feet on the incline. The new shaft has beensunk at a pitch of about 20 degrees one hundred and eighty feet in depth,which will strike a line through the incline one hundred and fifty-sixfeet from where the stopes terminate. This gives a vertical depth oftwo hundred and sixty feet from the top of the old incline shaft. It ithe opinion of all in this branch of mining that in stoping this one hun-dred and fifty-six feet large returns will reward the lessees, which theyundoubtedly deserve. During the period of fifteen months ending July,L890, this property has produced in bullion $198,764. ■

The mine is opened by a tunnel about two hundred feet in length, and near its face the l
