From the iirst three lines, or bases, and the horizontalangles observed at the several stations, a very large and ac-curate pl.-.n of the whole survey was constructed, forming amap of 4 feet long by 4 feet broad, which was verified inevery part by ? the measures of the computed lines, both thoseabove-mentioned, and others, and they were generally foundto agree very exactly, according to the scale by which theplan was constructed. The use of this large map was, to re-ceive and admit of the distinct and accurate exhibition of thefigures in their true places, expressing the number of feet inelevation or depression, with respect to each observatory, ofevery point and section of the ground, whose elevation ordepression might be observed. But before proceeding to thecomputation and construction of the points in the sections, wemay here abstract the numbers which express the relative ele-vation of the principal original points in the survey, beingthe extremes of the lines whose lengths are above abstracted.'
