Abstract	Sextant angle graphs are w idely used by hydrographic surveyors for plotting on large scale surveys; the principles governing their geometrical construction and use need not, therefore, be discussed here, and it w ill be assumed that the reader is familiar with the usual methods o f preparing such graphs. In certain cases, particularly when very large scales are chosen for a survey, the straightforward method of drawing up circles by beam compass cannot be used because of the large plotting distances involved. Normally in such cases points along the arcs of circles are computed, plotted and the arcs drawn with splines or railway curves. There are several methods of computing and constructing graphs in this manner, but all involve a certain amount o f laborious calculation and plotting as a preliminary to the actual drawing o f the arcs of constant angle.
