                                                           Still, James and Wrinkle were not without critics. It was reported that a
                                                           connection of the Savage Mine with the Sutro Tunnel was made by the
                                                           pair, and out of position by one foot. The Lyon County Times, a Silver City
                                                           newspaper, groaned about the “long winded puffs of James and Wrinkle,
                                                           the surveyors, because they were only one foot out of the way in a drift
                                                           270 feet in length.”. Presumably James and Wrinkle were happy with
                                                           the result, while the reporters in Silver City pointed out that a foot was
                                                           nothing to brag about and listed other imprecisions they alleged were
                                                           made by the pair. 13

                                                           In 1881, Ike James relocated to Arizona to take charge of the Conten-
                                                           tion Mine near Tombstone. In 1884, he became Superintendent at the
                                                           Carlisle Mine, in Silver City, New Mexico. But two years later James
                                                           resigned and returned to southern California, where he died in 1887.
                                                           By then, Wrinkle had hung out his own shingle as a U.S. Deputy Mineral
                                                           Surveyor. He surveyed claims around Tonopah, Bodie and points south.

                                                           The local newspapers regularly reported the filing of  mining claims, etc.
                                                           In April of 1881, Wrinkle himself located a ledge in the Virginia Mining
               Wrinkle’s map of the undergound in the Julia Lode,
                        Nevada Bureau of Mines             District, which he called the “Porphyry Lode Claim”. He obtained several
        patents for mineral land in Elko and Mineral Counties,
        Nevada. In February of 1888, Wrinkle and his friend Gotth
        Haist jointly located the “Valentine Claim” near Silver City.
        In the winter of 1899, Wrinkle produced six mineral
        surveys on the northeast flank of Candelaria Mountain, at
        the mining camp of Candelaria, Nevada. There is nothing
        remarkable about those surveys, Nos. 1886-1891, but his
        choice of equipment is noteworthy.

        Wrinkle preferred the Light Mountain Transit, manufac-
        tured by A. Leitz & Company of San Francisco. This instru-
        ment was lighter and more compact than the traditional        Wrinkle’s advertisement, Walker Lake Bulletin,
                                                                          Hawthorne, Nevada, Aug 13, 1884
        engineer’s transit of the day and specifically designed for
        mine or mountain work. Typically, these weighed about twelve pounds with the solar attachment, vertical arc and clamp, as advertised
        in the Lietz Catalog.

                                                     They were used on “extension tripods”, those with adjustable legs, in a day
                                                     when stiff-legged tripods were the rule. They were prized for their portability
                                                     and flexibility in the mountains and underground.
                                                     Wrinkle’s transit was equipped with a Burt solar attachment, similar to those
                                                     used on the Burt Solar Compass. This allowed for the determination of astro-
                                                     nomical meridian by solar observation, although Wrinkle typically included a
                                                     star shot for azimuth. His field notes from the Candelaria surveys report, “The
                                                     courses were turned off from a true meridian line, determined by me from observa-
                                                     tion of Polaris at its upper culmination.”
                                                     Wrinkle’s notes also mention his use of the Grumman Patented Steel Chain.
                                                     This 33-foot chain was a novel improvement over the usual Gunter’s chain. Pat-
                                                     ented by Josiah M. Grumman in 1859, it was made from No. 18 tempered steel
                                                     wire making it lighter and stronger than iron chains. It used a circular eye at one
                                                     end and an oval eye on the other, so as to fold together more readily, thus dis-
                                                     pensing with extra rings typical of iron chains. There was a spring balance and a
                                                     level bubble on one end, for proper horizontal chaining at the right tension, and
                                                     a mercury thermometer on the other, together with a temperature adjustment
                                                     collar. All this was explained in Grumman’s paper, A Short Treatise on Surveyors’
                                                     Chains & Chain Measuring with the Subject of Measurements Generally, in the City
