Excerpt from Geological Survey of Louisina: Notes on the Geology of the Winnfield Sheet
It is very evident that when any kind of work is carried on by different organizations, State and National, for somewhat different purposes, the results obtained will be of a different kind and of varying general value or accuracy. It seems, therefore, highly desirable that one organization, or one government bureau, should at least set the standard if not actually control the constructional work. Economy demands this. All cannot map the same area to advantage to the State or Nation. In Winn Parish, a part of which forms the subject of the present Bulletin, the State Survey, the United States Geological Survey, and the Soil Survey have each made a substantial contribution towards the final mapping of the region. First the State Survey mapped with detail six townships in the immediate vicinity of Winnfield, townships as a rule known to contain mineral wealth, or points of unusual geologic interest. The topographic map herewith given (Pl. I) indicates the class of work and the area covered. Notice that the scale is the same as that used in the majority of work done by the United States Geological Survey, 1/62, 500. The contour interval is also the same (20 feet). Heights are expressed in feet above mean sea level. But that this work might fit into the general scheme of quadrangular 15' maps published by the United States Geological Survey, the writer suggested to that organization the desirability of accepting such portions of the area shown on Pl. I as could be used in a 15' area and making such additions laterally as would serve to finish out a sheet of the ordinary standard type. This work is already well under way. The writer also urged the United States Soil Survey to study the distribution of the various soils in this region, the inducement held out to that organization being the detailed completed topographic map of at least six townships in the central portion of the area to be studied. This in turn led the Soil Survey to make further demands on the United States.
