1. The hammer-head shall be of solid iron, perfectly round, standard weights, 16 and 12 pounds, exclusive of handle. Length of handle three feet six inches over all. The handle should be made from split white hickory wood.

2. The competitor must stand at the scratch with one foot touching the scratch-mark. He is at liberty to throw with one or both hands.

3. Touching the ground, over the scratch-mark, with any portion of the body before the hammer strikes, shall be declared "no throw," and must be recorded as one of the three trials.

4. Permitting the hammer to carry a competitor from his balance or letting the hammer go out of time must stand as one of the three trials.

5. When the head and handle strike the ground at the same time the head or iron is the measuring mark, at the first break of the ground made by it. Should the handle strike first, one length of the handle, in a direct line with the throw, must be added. The measurement must be from the scratch-mark, midway between the thrower's feet, to the first break, in accordance with above rules.

Note.—In soft or clay bottom there is no difficulty in getting accurate measurement, but in quick or shifting sand close attention is required.
