Peculiar people, these toilers in the interplanetary voids; flotsam and jetsam; for the most part the very scum of space. Some solar systems contain vastly greater amounts of asteroidal and meteoric débris than did ours of Sol; others somewhat less; but all have at least some. In the main this material is either nickel-iron or rock, but some of these fragments carry prodigious values in platinum, osmium, and other noble metals, and occasionally there are discovered diamonds and other gems of tremendous size and value. Hence, in the asteroid belts of every solar system there are to be found those universally despised, but nevertheless bold and hardy souls who, risking life and limb from moment to moment though they are, yet live in hope that the next lump of cosmic detritus will prove to be a bonanza. Some of these men are the sheer misfits of life. Some are petty criminals, fugitives from the justice of their own planets, but not of sufficient importance to be upon the "wanted" lists of the Patrol. Some are of those who for some reason or other--addiction to drugs, perhaps, or the overwhelming urge occasionally to go on a spree--are unable or unwilling to hold down the steady jobs of their more orthodox brethren. Still others, and these are many, live that horridly adventurous life because it is in their blood; like the lumberjacks who in ancient times dwelt upon Tellus, they labor tremendously and unremittingly for weeks, only and deliberately to "blow in" the fruits of their toil in a few wild days and still wilder nights of hectic, sanguine, and lustful debauchery in one or another of the spacemen's hells of which every inhabited solar system has its quota. But, whatever their class, they have much in common. They all live for the moment only, from hand to mouth. They all are intrepid spacemen. They have to be--all others die during their first venture. They all live dangerously, violently. They are men of red and gusty passions, and they have, if not an actual contempt, at least a loud-voiced scorn of the law in its every phase and manifestation. "Law ends with atmosphere" is the galaxy-wide creed of the clan, and it is a fact that no law save that of the ray-gun is even yet really enforced in the badlands of the asteroid belts.
