“Wait,” MacEwan said urgently. “Both of you have lifted much heavier weights. I think the Tralthan is caught, perhaps impaled on a structural projection, and you cannot move it because—”
“We cannot move it,” the polite Hudlar said, “because we have been expending large amounts of energy after insufficient sustenance. Absorption of our last meal, which was overdue in any case, was halted by the accident after the process was scarcely begun. We are as weak as infants, as are you and your Orligian friend. But if you would both go to the other side of the being and push, your strength, puny as it is, might make a difference.”
Perhaps it wasn’t the polite one, MacEwan thought as he and Grawlya-Ki did as suggested. He wanted to apologize to we Hudlars for assuming that they were simply organic pieces of heavy rescue machinery whose capabilities he had taken for. But he and Grawlya-Ki had their shoulders under the side of the Tralthan’s cranial dome, their puny efforts were making a difference, and, unlike Hudlars, MacEwan needed breath with which to speak.
The Tralthan came upright, rocked unsteadily on its six, widely spaced feet, then was guided toward the other casualties by the Orligian. Sweat as well as chlorine was in MacEwan’s eyes so he did not know which Hudlar spoke, but presumably it had been the one engaged in lifting injured Illensans into the damaged transporter.
“I am having difficulty with a chlorine breather, Earthper-son,” it said. “The being is abusive and will not allow me to touch it. The circumstances call for a very close decision, one I am unwilling to make. Will you speak to it?”
The area around the transporter had been cleared of casualties with the sole exception of this Illensan, who refused to be moved. The reason it gave MacEwan was that while its injuries were not serious, its pressure envelope had suffered two small ruptures. One of these it had sealed, after a fashion, by grasping the fabric of its envelope around the tear in both manipulators and holding it tightly closed, while the other one it had sealed by lying on it. These arrangements had forced it to increase the internal pressure of the envelope temporarily, so that it no longer had any clear idea of the duration of its chlorine tank and asphyxiation might be imminent. But it did not want to be moved to the relative safety of the transporter, which was also leaking, because that would allow the lethal atmosphere of the lounge to enter its envelope.
“I would prefer to die of chlorine starvation,” it ended forcefully, “than have my breathing passages and lungs instantly corroded by your oxygen. Stay away from me.”
MacEwan swore under his breath but did not approach the Illensan. Where were the emergency rescue teams? Surely they should have been there by now. The clock showed that it had been just over twenty-five Earth minutes since the accident. He could see that the sightseers had been cleared from the lounge’s inner wall, to be replaced by a Nidian television crew and some uninformed ground staff who did not appear to be doing anything at all. Outside there were heavy vehicles drawn up and Nidians with backpacks and helmets scurrying around, but his constantly watering eyes and the ever-present plastic hangings kept him from seeing details.
MacEwan pointed suddenly at the hangings and said to the Hudlars, “Will you tear down a large piece of that plastic material, please, and drape it over the Illensan. Pat it down flat around the being’s suit and smooth the folds out toward the edges so as to exclude our air as much as possible. I’ll be back in a minute.”
He hurried around the transporter to the first Illensan casualty, whose body had turned a livid, powdery blue and was beginning to disintegrate, and tried to look only at the fastenings of the chlorine tank. It took him several minutes to get the tank free of the body harness, and several times his bare hands touched the dead Illensan’s flesh, which crumbled like rotting wood. He knew that oxygen was vicious stuff where chlorine breathers were concerned, but now he could really sympathize with the other Illensan’s panic at the thought of being moved in a leaking suit.
When he relumed it was Grawlya-Ki who was smoothing out the plastic around the Illensan while the two Hudlars were standing clear. One of them said apologetically, “Our movements have become somewhat uncoordinated and the chlorine breather was worried lest we accidentally fall on it. If there is something else we can do—”
“Nothing,” MacEwan said firmly.
He turned on the tap of the chlorine tank and slipped it quickly under the plastic sheet and pushed it close to the Illensan. The extra seepage of the gas would make little difference, he thought, because the whole area around the transporter was fast becoming uninhabitable for oxygen breathers. He pressed the tiny mask hard against his face and took a long, careful breath through his nose, and used it to speak to the Hudlars.
“I have been thoughtless and seemingly ungrateful for the fine work you have been doing here,” he said. “There is nothing more that you can do. Please go at once and spray yourselves with the necessary nutrient. You have acted most unselfishly, and I am, as are we all, most grateful to you.”
The two Hudlars did not move. MacEwan began placing pieces of debris around the edges of the plastic and the Orligian, who was quick on the uptake, began doing the same. Soon the edges were held tightly against the floor, the gas escaping from the tank was beginning to inflate the plastic, and they had the Illensan in a crude chlorine tent. Still the Hudlars had not moved.
“The Colonel is waving at you again,” Grawlya-Ki said. “I would say with impatience.”
“We cannot use our sprayers here, Earthperson,” one of the Hudlars said before MacEwan could reply. “The absorption mechanism in our tegument would ingest the toxic gas with our food, and in our species trace amounts of chlorine are lethal. The food sprayers can only be used in a beneficent atmosphere or in airless conditions.”
“Bloody hell!” MacEwan said. When he thought of the way the Hudlars had worked to free the casualties, knowing that their time and available energy was severely limited and letting him assume that they had no problems, he should have had more to say — but that was all that came out. He looked helplessly at Ki, but the Orligian’s face was covered by its furry hand holding the ridiculously small mask.
“With us,” the other Hudlar added, “starvation is a rapid process, somewhat akin to asphyxiation in a gas breather. I estimate that we should lose consciousness and die in just under eight of our small time divisions.”
MacEwan’s eyes went to the concentric circles of the lounge clock. The Hudlar was talking about the equivalent of about twenty Earth minutes. Somehow they had to get that boarding tunnel open.
“Go to the tunnel entrance,” he said, “and try to conserve your strength. Wait beside the others until—” He broke off awkwardly, then said to the Orligian, “Ki, you’d better get over there as well. There’s enough chlorine in the air here to bleach your fur. Keep passing the masks around and—”
“The Colonel,” Grawlya-Ki reminded him as it turned to follow the Hudlars. MacEwan waved acknowledgment, but before he could leave the Illensan began speaking, its voice muffled by the fabric of the makeshift chlorine tent.
“That was an ingenious idea, Earthperson,” it said slowly—“There is now a beneficent atmosphere surrounding my sure envelope, which will enable me to repair the torn fabric and survive until Illensan assistance arrives. Thank you.”
