Hay slips, or hay skids, are used on the old smooth fields in the eastern states. They are usually made of seven-eighths-inch boards dressed preferably on one side only. They are used smooth side to the ground to slip along easily. Rough side is up to better hold the hay from slipping. The long runner boards are held together by cross pieces made of inch boards twelve inches wide and well nailed at each intersection with nails well clinched. Small carriage bolts are better than nails but the heads should be countersunk into the bottom with the points up. They should be used without washers and the ends of the bolts cut close to the sunken nuts. The front end of the skid is rounded up slightly, sled runner fashion, as much as the boards will bear, to avoid digging into the sod to destroy either the grass roots or crowns of the plants. Hay usually is forked by hand from the windrows on to the skids. Sometimes hay slings are placed on the skids and the hay is forked on to the slings carefully in layers lapped over each other in such a way as to hoist on to the stack without spilling out at the sides. Four hundred to eight hundred pounds makes a good load for one of these skids, according to horse power and unevenness of the ground. They save labor, as compared to wagons, because there is no pitching up. All hoisting is supposed to be done by horse power with the aid of a hay derrick. [Illustration: Figure 149.--Double Harpoon Hayfork. This is a large size fork with extra long legs. For handling long hay that hangs together well this fork is a great success. It may be handled as quickly as a smaller fork and it carries a heavy load.] [Illustration: Figure 150.--Six-Tined Grapple Hayfork. It is balanced to hang as shown in the drawing when empty. It sinks into the hay easily and dumps quickly when the clutch is released.] WESTERN HAY DERRICKS
