 was hauled in from Guaymas, fud draft horses were imported especial ly 10 bring it in. The old Maria company was apparently a "plunger. Tor there is a handsome house. % by 40 feet, made of hand-faces stone, which cost them $2O.OOO. and their other improvements were made regardless Of cost. In speak ing of the geology of the Carmen and of the camp in general, Mir. van Siclen, who is chief engineer. stated to me: The country generally is
 rbyolite and rhyolite tuffs and ande- site tuffs, covered in places by more recent lavas. The Mercedes IS located in a hin of cretacious
 hmeStone suTlounded by igneous rock. like an island in an ocean. and there are several of these in this region. In the deep shaft of the Carmen we found what was di- agnosed as a ''porphyrite," but 1t is really a rhyolite tuff. The veins are true Assures; all run northeast and southwest and have an almost yer. tical trend. Some of tho veins show movement-that they were fault ifs sures. The veins are filled with
 secondary quartz and secondary Csl- cite. The ore-bearing minerals are argentite, polybasite. stephanite, proustite. Most of the veins carry little gold. There are 300 veins | between Carmen and Chispas, a dis tance of four miles, and these in clude the Carmen. Granaditas, Bs- bacanori, Wm. Tell, Chispas, these being the main and producing veins. All run in the same direction, al,
 have the same filling, and all are in The same country rock"
 Chispas Power Plant
 The Chispas power plant at the mine includes two Ingersoll-Sargeant cOmpressors. a l-ton ice plant, two Sterling boilers, well equipped ma chine shop, small dynamo generating i electricity for lights. This also is the terminus of the tramway, eight miles in length which brings wood and supplies from the terminal of the wagon road. At the mill, a mile from the mine. there are four small
 boilers and 110-h. D. Corliss engine
 An air compressor is used by tho riveters in putting up the steel tanks and will be used for agitation in the cyanide plant when it is com pleted. There is one 10 kw dynamo generating no volts and one 40-kw dynamo generating 250 volts, the latter directly connected to 8 Buff falO Forge Co automatic engine. This latter will furnish lights for the camp and for some of the power Fl. w Austin is master mechanic.
 The telephone service is excellent, with one longdistance line to Car men. foUr miles and one six miles 10 the terminal Of the tTamway, the latter being a common return sys- tenn, having thirteen phones. The ringers are for 500 to 2000 ohms- The construction is a 3inch pipe having a wooden head and bolted arms and pins and insulators; using Nos 9 and 10 wire. The crossarms are of native wood. The service is excellent.
