| View Cart ⇗ | Info

“In water—lining a stream of varying width, the lines are not to be crowded so as to be carried through the narrow portions, but corresponding lines should be brought together in the middle of the stream as illustrated. Care should be taken to avoid any spots of sudden increase or decrease.” —French, 1911
