 Richmond is a skillful assayer. having spent much of his life in that line of activity. Approaching the future of the Mansfield he considered it worth while to plan for permanency and has therefore equipped an assay office, perfect in every detail and much bet ter than many little plants of the same size doing a custom business. He has all the facilities as well as the inclin- ation for knowing just what comes out of the ground. Just above this is the pump house where the water is raised fl om a good well on the creek bank to a tank on the hillside from which the camp Is supplied.
 On the gentle slope of the hill above the boarding house, on the two sides of a street are two double tents. boarded. with corrugated iron flies and fourteen single tents of similar construction. Four more tents down the wash oc- cupied by MeXicans, complete the structures belonging to the company, the total furnishing homes for the 65 miners and other employees of the camp as well as the families of some of them. To complete a description of the settlement mention is made of a dozen or so tents in the nearby wash. occupied by the families of Mexican woodhaulers and contractors so the population of the little village will number approximately hundred people. The construction of the Mans field buildings is chiefly of wood and corrugated iron except the tent houses in which these materials also figure While not fireproof it is the nearest approach to it of any available style O. architecture and the ample room at hand makes unnecessary the crowding of buildings. Should one structure burn the rest of the camp need not be destroyed except high winds prevail.
 This Is concise general descrip- tion of the camp facilities. Ore is not mined in buildings but a complete camp equipment is as necessary to large mining operations as a reduction plant. It is a heavy initial ex- pense and too often operators seek to avoid it by makeshift structures that cost but little less and need constant replacement. There is no sign of ex- travagance in the Mansfield construc- tions yet everything built has been with an eye to permanency and con- venience. Money has been expended but judiciously, and like the develop ment work to date, it will not have to be done over again.
 MANSFIELD CANYON.
 Next in order Is a description of the mineral development, and a little words" eye view of the topographi- cal situation will perhaps aid the reader in following the writer Ima- zine the little stream known all over that section as Mansfield canyon. on both sides of which are the workings Of the Mansfield corhpany which takes Its name from the canyon. The gener- al course of this stream is almost ex- actly from west to east though it winds to the north and south of this general course, alternately and re- peatedly, matter of perhaps 200 yards, twisting like a snake as it fol- lows a straight road. On either side Of this canyon rises a range of hills several hundred feet high and very precipitous. Standing at the mouth of the canyon, near the camp, and look Ing to the west, one sees to the right the hills rise range on range until the summit of the Santa Ritas or Mount Wrightson appears several miles away. All the intervening country from the Mansfield is covered with pine and oak timber. On the left or south the mountains also continue with alter Li-ting range and gulch, but their all titude grows less and less until several miles away the range fades into de- sert It is only with the Mansfield canyon and the first range on either side, that this article has more to do, for the properties of the Mansfield company, some 27 claims of full size, approximating $50 acres, lie up this gulch and the two rows of adjacent hills. In a general way the claims run parallel with the gulch; that is their greatest length being up and Gown the creek and the property vary ing from one to two or three claims in width at different places. The claims are in two groups. the lower one nearest the camp being known as the Mansfield group and the upper claims being known as the Ruby group It is c matter of about three miles right up the canyon, from the camp to the west ern end of the Ruby group; but in tervening is a spot of ground about tcree claims in size that belongs to neighborinE operators. This upper or Ruby group is also known locally and in camp as the canyon" group, the appellation being significant and used to distinguish these workings from those on the original Mansfield. White, black and other varieties of oak. as we'll as mesquite trees and the many species of desert brush. cover the low Ter end of the canyon and the surround ing hills, clear down to the edge of the desert. About midway between the two groups of claims the pine tim Der begins. so the upper group is quite heavily forested with pine. juniper and the various kinds of oak.
 A SULPHIDE DISTRICT.
 As usual with mineral deposits in mountainous countries, the values ap- pIoach more nearly to the surface the further up the canyon one travels or the higher the ground. This is par ticularly true in a sulphide district which the Mansfield is almost exclu- sively. Oxidized ores are encountered only on the surface and then in but small quantity. though huge iron dike: crop at frequent intervals all along the canyon. Large parallel veins TUT lengthwise with the canyon, some-
