Incredulously, I got to my feet. I saw then that the thief was not a man, but a boy--the tiniest boy that I have ever seen in my whole life. Assuming his stature to be average, it is unlikely that even a full-grown adult of his species would come any higher than a Frimm 4's citizen's knee-cap! I called after him, uttering my name in as gentle a tone of voice as I could manage and assuring him that if he would return the articles he had stolen no harm would come to him. He only ran the faster, and fairly streaked through the galley doorway, down the entrance corridor, and out onto the greendeck. I had no choice but to set off in pursuit, and this I did, naively believing that I could overtake him easily. In this I erred indeed. Never have I ever seen anyone run so fast. Why, there were times when I could have sworn that his feet weren't even touching the deck! As I lumbered along in his wake, I wondered how he could conceivably have gotten on board. Had he climbed the capillary tube? This didn't seem possible in view of the _Uxurient's_ altitude and in view of his diminutiveness, but I could think of no other answer. There was no need for me to, I saw presently: that he had climbed up the tube was unequivocably demonstrated by the ease and the celerity with which he now began to climb down it. (3) _Why the_ Uxurient's _Flexible Ship-to-Ground Capillary Tube is now Ten Exids Shorter than It used to be_ Loath to give up the chase, I started climbing down the tube myself. This is not as difficult as one would at first imagine--as I myself had imagined, in fact, prior to making the attempt. The branch-like protuberances that absorb the sunlight and transmute it into the energy required for the capillary-action provide numerous hand- and footholds, and had it not been for the almost gale-force wind that had developed, my descent would have been relatively easy. Even with the wind, I found myself in no great danger, and I have no doubt but what I would have reached the ground in due course had I not underestimated the resourcefulness--and the blood-thirstiness--of my youthful quarry. He kept calling out repeatedly at the top of his voice, but I did not suspect what he was up to until, halfway down, I paused and looked below me. I was just in time to see a woman run out of the thatch-roofed dwelling near which the tube had rooted itself and hand him a small object the very moment his feet touched the ground.
