This leads up to a broader proposition, which may be stated thus: That the general tendency of surveying organizations is in the direction illustrated by that of the "French Staff." Organized originally for map-making, they progress little by little in the direction of devoting their energies to geodetic work, while at the same time the topographic work proper, for which they were created, is belittled and neglected. As a consequence the latter depreciates in quality and diminishes in quantity; the main purpose of the organization is lost, and a mere means becomes the ultimate end of the work. This tendency should be recognized in map-making organizations. The weakness of our modern maps is seldom in the primary control. It is easy to do triangulation of sufficient accuracy for the control of maps upon such scales as that above considered, little knowledge or experience being required beyond that gained at our engineering schools; while the more accurate triangulation, generally known as geodetic work, requires merely better instruments, more time, and more experienced observers. The weak features of maps are generally the details, the part of the work that, strange to say, is usually relegated to the lowest grade of professional men. This weakness consists in an insufficiency of minor locations for the control of the sketch and in unfaithful sketching. It is the sketching that requires the most careful attention and the best and most experienced men. The instrumental portion of the work is the least difficult; the artistic portion, or sketching, is the most difficult. It would seem more logical and would doubtless produce better results to reverse the {252} usual order of promotion and place the topographer above the triangulator. Moreover, the triangulation should be regarded as merely a means for the correction of the sketching, and it should be required only that it be of sufficiently high grade to meet this condition. The minor locations should be sufficiently numerous and well distributed to fully control and correct the sketching; and finally the sketching should be as faithful a representation of the topography as is consistent with the necessary generalization of the surface features.
