Sinopsis
Excerpt from Methods of Mine-Timbering
Before Deidesheimer's square set system came into use, the ingen ious placing of posts, caps, and stulls constituted the only method of timbering, the multitude of conditions met in the mines making the combinations almost endless. Where veins occur in firm, solid rock, being perpendicular, or near it, the danger of caving is greatly lessened, and the amount of timber required is reduced to a minimum, but these conditions are exceptional.

Excerpt from Methods of Mine-Timbering
There is no attempt in this Bulletin to present a complete treatise on methods of mine timbering, but simply to give consideration to those systems ordinarily used in, or adapted to, the gold mines of California. Both in the lode and deep gravel mines of this State, those systems in use have been selected from the best practice and applied in various ways according to circumstances. In collecting the material herewith presented, many mines have been visited and the details of timbering work noted, so that those who have not an opportunity of comparing methods for themselves may be enabled to learn the practice of others.
It has been thought proper also to give some detailed account of systems of mine timbering used in other States where extensive ore-bodies are worked, since these are adapted to use here under corresponding conditions.
