Fence.
Patent for a new and improved fence. This design calls for two spring-bars to be driven into the ground alongside two crossbars and laced between the latter. This lacing of spring-bars allows for "much additional bracing strength" for the crossbars and enables barbed wire to be stretched along where the spring-bars intersect (line 33).
