Improvements in means of transportation, routes and trails to the mines will go on from time to time. Changes in cost of provisions and mining supplies, and in modes of mining will take place. Regarding all this we shall be promptly informed and will, at all times, be in possession of the latest information. Questions regarding routes, cost of outfit, transportation, or regarding any other matter connected with mining or the mines, will be answered by letter, written by experienced miners in our employ here, for a fee of $1 enclosed with each query.
