one of the half dozen other "gangs" in that section of the country which I knew as Pennsylvania and New York States. Wilma cleared up for me the mystery of those flying leaps which she and her assailants had made, and explained in the following manner, how the inertron belt balances weight: "Jumpers" were in common use at the time I "awoke," though they were costly, for at that time inertron had not been produced in very great quantity. They were very useful in the forest. They were belts, strapped high under the arms, containing an amount of inertron adjusted to the wearer's weight and purposes. In effect they made a man weigh as little as he desired; two pounds if he liked. "Floaters" are a later development of "jumpers"—rocket motors encased in inertron blocks and strapped to the back in such a way that the wearer floats, when drifting, facing slightly downward. With his motor in operation, he moves like a diver, headforemost, controlling his direction by twisting his body and by movements of his outstretched arms and hands. Ballast weights locked in the front of the belt adjust weight and lift. Some men prefer a few ounces of weight in floating, using a slight motor thrust to overcome this. Others prefer a buoyance balance of a few ounces. The inadvertent dropping of weight is not a serious matter. The motor thrust always can be used to descend. But as an extra precaution, in case the motor should fail, for any reason, there are built into every belt a number of detachable sections, one or more of which can be discarded to balance off any loss in weight. "But who were your assailants," I asked, "and why were you attacked?" Her assailants, she told me, were members of an outlaw gang, referred to as "Bad Bloods," a group which for several generations had been under the domination of conscienceless leaders who tried to advance the interests of their clan by tactics which their neighbors had come to regard as unfair, and who in consequence had been virtually boycotted. Their purpose had been to slay her near the Delaware frontier, making it appear that the crime had been committed by Delaware scouts and thus embroil the Delawares and Wyomings in acts of reprisal against each other, or at least cause suspicions. Fortunately they had not succeeded in surprising her, and she had been successful in dodging them for some two hours before the shooting began, at the moment when I arrived on the scene.
