B. Nickle, Hoycville, Mich. on the above szated farm. To eszablish this standard, I proceeded as follows: Compared a 100 ft. engineer's chain with the stan- dard at the Michigan Agriculaural College, and found the chain tc be 1-2 inches too lcnge Placed two 6" x 6" x «' sound oa« timbers «ertically in the ground with the tops flush, and approximately 10G ft. apart; then drove a bolt in each timber and markec the i100 ft marx upon the bolt heads, by comparing the 100 ft. chain tested at M. A. ©. and making, allowance for the error of |].z". Also placed a smailer tir- ber midway between the 10t ft. marass for use in testing a a 108181 50 fte chain. investigation of section corners. Collection of e=iderce. Received irom the state land office, Laising, Mich., a copy cf the field nutes of the original ,overnment survey made in 1627 by Urange kisdom, surveyor. Mace in\es- tigation for monumer.t at the correr of sections 14, 1b, ll, a.d 1C, but could find no trace of the land marks as stated in the tield notes ot the original survey. Spent consiuerable o!; tine In dig, ing at the incersection of roads where | thought the monument would be lecated, but found no indicavions of the original monument except a decayed log which according to. an Old settier had be piaced along besiue the monument. Made investivation tor 1/4 section post between sections 10 and 11, but could find no evidence of witness trees as stated in notes o1 the orginal survey. Located approximactely by line fences wnere the monument should be ano Cus Gown in the middle of the road, anu found an iron bur 1" x 1" inside of a 3" tile. Suspended a plumb bob di- rectly over the bar, end removec the bar ard tile: urder- neath tiese, | founda a circular spot cf aitierent colored earth which I concluded was the remains of the original stake as it was directly below the plump boke Then placed tne tar ana tile carefully back in the originai position, ard arove u small wooaen siake directlv o'er the monument forluiure relierenceée in,esctigated 1/4 section post beiwwan 10 and lt, and found the top of a large stone at tne iniersaction of fences and roac. this stone was, according to vu. be Nickle, placec direct)y over the original monument by county sur- veyor Davis in 1557 (was never recordea). ihe stone was originall, marked by a cross on the highest projection, but unfortunately, the portion bearing the cross became ex- posed to trafiic, and was chipped oif. i ;laced another cros: upon the stone rhcre | thourht it should ce and feel ccn- fident that it 1s not in error more than 1 1/2". this stone is at the S. We. corner of the &U acres under consiueration, and is station © for ail levelirg ara coltour work. Mace no rurther dnvestigation for monuments at section cozrneis, bu: concludeac to agsune one cf the pounda- ary lines, of tne acreo.e stated &U acres, as a meridian. “Investigation_of land cerners. Ac the S. E. cornei in the middle of the road, found « ti.e shaped piece of crockery placec there by Lavis, country surveyor. Toor the center of the same as the land COrNnere At the N. E. corner. | found a 4" x 5" oak post droie at ihe inversection of the fences. Ac tne Ne. We. cornei. Il found a small staxe ut the intersection of the fences. -- Le.eling -- Locaziie_stations: Located all sations by means or rectangular co- ordinates, dividing the entire SU A~w ino £O' squares. As- sumed east ana west line between SG. We and S.- Be corners as -9- axis of abscissee and N. znd S. line berween S. We. ard Ne. #. corners as exis of ordinates: the origin being mon- uiert av the S. WwW. corner. Points on the axis 0: abscissas are are desig- nated ty O, A, LE, Cy etc., ana on the axis oi ordinates by C, 1, 2, 5, etc. Thus to locate stae H - 15, we would find it 400 ft. E. ard 900 f{+t. N. of sta. O or the oriyin. Ali fields are approximately rectangles, and hence measured the boundaries of the field and set poles FC it. apart paraliel to the fences ana corresponding to stations along the axes. Thus fcr the rodman to locate any station, iit was necessary for him to line himself up with the proper poles. ihis method proved very satisfactory ana convenient as all the stations were located on Lk. and We lines: thus the rodman would start out at Sta. O - 10 and walk directly toward the corresponding pole on the BE. side of the field, stopping every 5O ft. wher. in lize witn the N. and S.- poles and allowing the leveler to taxe a reading. The stations -]Q- would read in field notes, 10 - O, 10 - A, 1G- 15, etc. . Blevations ‘11 ele.aticns were taken with trapsit on en- gineer's levels; special care being taker to keep the in- strument in adjustment. All readings on turning points and bench marks were taken carefully to the nearest O.001 of a foot, and «ll those cf regular stations were read to the nearest O.l of a foot, with le'eling rod placed airecily upon the Bround. Ir sume cases this necessitated the scrap- ing of snow orf.the siaticn. bench marks Took as principal b. hk. cross on stone window si:l, Ne window or the W. side of brick residence ol J. Db. Nickle.
