than my little carbine size .22 Hornet, another gun that Westley Marks probably would have sneered at but which I wouldn't have traded for all the automatics you could shake a stick at. I didn't take much else; no clothes except the shorts I wore when I climbed into the shuttle rocket for the space station. When Marks said freight rates in space were high he just wasn't whistling, Terra Forever. I could buy clothes and any other equipment I needed a good deal cheaper on Mars than the cost of transporting them there would come to. For one thing, when anybody left the colony planet to come back to Terra, they invariably left behind everything in the way of clothing and personal equipment; for another, a certain amount of these things were being manufactured on Mars from native raw materials in an attempt to escape the murderous space rates. After the four G's acceleration had cut off and we were in free fall, I took the opportunity to read the contract I'd hurriedly signed with Westley Marks. On thorough reading, the contract didn't seem too bad. All my expenses to and from Mars were paid by Marks. I also got five credits a month in the way of salary—no fortune, but average pay for a Terran worker. If I caught a zloor and brought it back alive, I got a five hundred credit bonus; if I brought two back alive, a seven hundred credit bonus. If I brought a dead one back, I got a three hundred bonus. Westley Marks didn't seem to be interested in getting more than one dead one since there wasn't any provision for a larger number. He'd given me to understand that this job was for the government, but from the way the contract read I was working for the Marks Enterprises. That irritated me for a minute or so, but I finally shrugged it off. He probably had a government contract to secure one of the things. I still couldn't figure out what his angle was—but I knew there must be one; too much money was involved to make this a routine assignment such as I usually work on for the zoos. Evidently Marks ran some sort of an expediting outfit which took on off-trail contracts. At this point I might do a little in the way of describing my trip to the space station which circles Terra and is used as a take-off point to Luna and the planets. I might go on and tell of my journey from there to the space station in orbit about Mars, and then, further still, of my shuttling down to Fort Mars and my first impressions of landing there, of the one-sixth gravity, the thin air, the plastic dome which covers the whole little city. But the trouble
