(USNM cat. no. 289642; Smithsonian photo 44538-G.) Gurley accepted the offer and that by July 1885 they had begun handling whatever orders for meters Price received. In fact, they seem to ha\e taken over the remaining supply (about 4 or 5) of the 16 meters that Price had manufactured up to that time and sold them for him. A common criticism of the early Ellis meters was that they \vere too fragile for use on large rivers. In his meters Price had attempted to combat that criticism by making them much larger and far more rugged than the 18-inch Ellis meters. His original meter was a little oser 32 inches Jong. Gurley's first production model (their catalog no. 375) was even longer—35 inches. Both were made of much hea\ier inaterials than were the Ellis meters. Price's theory seems to have been that large rivers required large current meters, and the first models built by both Price and Gurley complied with that theory. Before Gurley's first production lot of the no. 375 current meters was completed. Price decided that a smaller meter might be easier to handle when meas- uring small streams. When, therefore, the Gurley firm introduced its new line of Price meters in 1887, that line consisted of two models (figs. 10 and 11)— the 35-inch model with a 7^-inch-diameter impeller (catalog no. 375) and a 24-inch model with a 6-inch- diameter impeller (catalog no. 376). In both in- stances, the impellers had five cups. Between the years 1887 and 1896, when a change in Gurley's model-numbering system went into effect, that firm sold 45 Price current meters, 19 of which were of the larger size (catalog no. 375), and 26 of which were of the smaller size
