 | "Methods of lowering ore. After the completion of the Sutro Tunnel the ore may be sent down the tunnel level into bins and cars by means of chutes as shown in the right-hand illustration; or it may be lowered in cars, E, placed on a cage with rope, D, attached, reaching to the surface, which is regulated by a breaker, B, controlled by one man, as shown on the left. The ore lowered from above in one compartment may be made to hoist men or timbers to any level in another compartment." Drawing. Copyright holder unknown. In Robert E. Stewart, Jr. and Mary F.

 | "A pilot tunnel was driven ahead at maximum speed by one crew while the enlargement and timbering were carried on by another. Candles attached along the wall in the pilot bore must have been duplicated in greater number behind the camera. This exposure must have taken a long time, as no men or mules can be seen. Economy of the operation is indicated by the wooden rails with thin strap iron on the running edges of the track. This was a method used in many of the 'depression' gold mines just a few years ago."

 | "Heat was always a problem on the Comstock. Long after the advent of Sutro's tunnel, it was the cause of cessation of deep mining. Good ore was left in the deeper levels when live steam and boiling water forced miners away. Miners are descending one of the shafts. The Comstock Lode, near Virginia City created one of the largest mining camps." Here Adolph Sutro tried to develop a perfect process for refining quartz ore. Copyright holder unknown. In Robert E.
