will describe only the most important ones.
 A very large zone of replacement
 is found at the junction of the north 20 degrees west with a north 45 de-
 gress west fracture which occurs on
 the Rincon near the common endline with the Jupiter. This one shoot is in places fifty feet wide and has an approximate length of two hundred feet The hanging-wall streak of cal cite and quartz here approximately fills the entire fracture, being ho-
 homogeneous mass on the hanging wall
 and fragmental as it hears the foot wal, where the replacement has been less complete.
 Ore deposition from this point fol-
 lows the north 45 degrees west frac- ture while the north 25 degrees west fracture is barren for several hundred feet until it cuts north 65 degrees
 west fracture known as the New York vein on the Comet claim, at which
 point small shoot of ore is formed
 in the east and west vein.
 The large north 45 degrees west vein, with varying width of calcite
 and quartz along the hanging wall
 and numerous east and west fractures
 joining it, continues through the Ju-
 piter and w. R. Hearst claims.
 From near the center of the Jupi-
 tar cln nt nf int
 with strong north 65 degrees west
 Assure entering from the footwall, or
 west side, forming a large replace
 ment deposit of calcite and quartz
 from ten to thirty feet wide and at
 least one hundred feet long; to the
 common endline ofthe w. R. Hearst
 and Hot time claims, distance of
 about fifteen hundred feet, three very
 large deposits have been formed.
 The deposit just described being the
 first; the second, which is connected
 to it by continuous vein of calcite
 and quartz, is located about two hun
 dred and fifty feet further northwest
 erly, being fully three sundred feet
 long and extending across the com
 mon endline of the Jupiter and w.
 F. Hearst, a distance of about one
 hundred and fifty feet. It is form
 ed by the intersection of a north 20
 degrees west fracture of secondary
 magnitude with the main north 45 degrees west vein in conjunction with
 small vogesite dike and accompany
 ing contact Assure which enters from
 the west with bearing of south 65
 degrees east at the southeast end of
 the. ore shoot on the Jupiter and a
 north 65 degrees west fracture, it. self much altered by replacement along it's walls, which enters from the east at the northwest end on the w. , R. Hearst. There are numerous small parallels to these which enter but have not been shown on the plat as they would only tend to confuse rather than aid the understanding of l the system. The third body is found at the common endline of the w. R. Hearst and Hot Times claims, at which point the north 45 degrees west vein meets and unites with the second north 25 degrees west main regional frac-
 ture (B) and the deposition is again , changed to the course of the latter. : It IS at this point that the New : York vein north 65 degrees west en- : ters and unites with the main frac- lures, evidently ending at this point, although extending east apparently
 for several miles. This orebody, from twenty to fifty feet wide and two hun . ,dred feet long, continues for fur . ther distance of five hundred feet as r & hanging-wall vein with an average width of ten feet, at this point it is joined by a strong north 65 degrees west fracture and a small vogesite dike, having the bearing of north 65 largement of zone of replacement.
 From this point the vein is hidden : for distance of three hundred feet l below the detritus of wash, outcrop-
 ping again strongly near the common , endline of the Hot Times and Yellow } Spar. It is near this point that frac- 7 ture co converging with (B) having bearing slightly more northerly than l the latter Ci. e., north 20 degrees . west) unites with it. It is apparent , that a short north 45 degrees west fracture joins the two at this point
 and the deposition follows the frac- ture to the union with co again form ing a moderate sized shoot.
 A this point we encounter a mem- l Der of the reversed system, fracture , having a bearing of north 20 degrees east together with more recent fault } having a bearing of north 45 degrees
 east which has slightly displaced the Assure. What is known as the Tango } vein outcrops to the north of this fault ors the Yellow Spar claim and } has bearing of north 20 degrees east } is twenty feet wide and is continuous from the fault through a saddle in , narrow ridge of hills, distance of | ,bo,,t f;ua bnpdred fact to wbara if
