Not illustrated. 1906 Excerpt: ...d, K, and T, for each I, instead of the d (or D) and b = T--K. Make a temporary record of--Q at each I. Check. Between any two places, Ed--2 Q, including + Q at the place nearer C, and--Q at the place farther from C. This applies between C and P. Other checks will appear after some experience. Record all surface lines to each point of survey on the, cross section. 32. Sometimes the center line of the work may run along the face of a steep hill side in such a way that the side stakes for a considerable distance along the line will all come very much above, or below, the surface of the ground at the center stakes, C. In such cases it is convenient to pass from one cross section to the next without returning to the center line to begin the survey of each cross section. It may also be found desirable to carry on the survey of two, or more, cross sections at the various settings of the level. The methods are outlined below. 33. To Stake Out One Cross Section from Another, measure out from the center stake, C, of the new cross section the same distance the tape mark, B, in use on the cross section for which the level is set, is from its center stake, and mark the place on the ground. Hold here the same slope tape reading that was in use there, either--K or-f. K, as the case may be. It will be--K provided a new mark B, which has been set preparatory to moving the level is used for reference, otherwise it will be + K. It may be noted that the distance of any tape mark, B, from its center stake, C, equals Db + (Q, from-(-Qb to--Q for B referred to), or equals S (Q, from-j-Qc to--Q for B referred to), or may be measured directly from C. Measure the distance directly from C and compare this measurement with the same distance obtained in one...
