Autograph Letter Signed “J.

In accordance with your telegram of the 18th Inst. the work on No. 8 was discontinued immediately and that upon No. 6 commenced. We had sunk about 20 feet on No. 8 and struck the crevice. The shaft on No. 6 is down about one hundred and twenty feet, but sunk very badly and if you contemplate working it extensively will require some little repair. There is a vein of iron about fourteen inches wide, the crevice or distance between the wall rocks being full four feet. The iron is by assay very rich...Mr. Keith so far has only run his mill on small scale, and is himself unable to estimate now the cost of extracting the Gold from the ore by the process he now intends adopting. Mr. Kimball of Mess.

Very good condition.
