The methods of measuring water in natural streams in a systematicand economical manner have been developed within the last twentyyears, largely by the efforts of the United States Geological progress has been made in simphf)dng details and in adapt-ing them to methodically carrying on work over a wide extent ofcountry. There has been a gradual evolution of the instrumentsemployed, especially along the Une of lightness and portability. Briefly stated, the work consists of measuring and recording thetotal quanti
