Why?”
“Your lives,” Dan answered. “Or, maybe, worse, brain damage.”
Mary shook her head. “That wasn’t at stake, dear, once you’d located us,” she said gently. “We could have waited awhile more.”
“I couldn’t be sure of that,” he said, with a slight upstirring of anger that she should be thus withdrawn. “I didn’t know how long you’d been marooned, and you just might have been among those people whose pressure tolerance is abnormally low.” As low as mine is high.
“We aren’t,” Ralph said. “But anyway, it was quite an exploit, and we owe you our sincerest thanks.” He paused. “And then you flew back at once, not even stopping to rest. I stand in awe.” He chuckled, though his heart wasn’t in it. “Or, I will stand in awe as soon as the doctor lets me out of bed.”
Dan was glad to shift the subject. “My job, after all.” He drew up a chair to face Eva and them. It was good to sit. Hour upon hour had drained him. (The flight from here to the valley again, through air that in places had gotten heavily turbulent; the hovering above the rampage; the squinting and studying, while the agony of the herd tore in him almost as if it had been his own; the final thing he did; and not even his triumph able to lift the weariness off his bones, during the long flight back.) Maybe he should have caught some sleep after his return, before coming here.
“Was it the terasaur you were concerned about?” Mary asked. “Eva told us you were going back to them, but she didn’t know more than that herself.”
He nodded. “Uh-huh. They’re an important part of the environment. I couldn’t pass up this chance to learn more about them, and try to save what was left.”
Eva half rose. Something of the woe behind her eyes disappeared. “Did you?” she cried.
“I think so.” A measure of joy woke likewise in him. “Frankly, I feel more like bragging about that than about a bit of athletics at a rope’s end.”
“What happened? What’d you do?” Eva reached toward him.
He grinned. The tide of his pleasure continued to flow. “Well, you see, terasaur do go rather wild in rutting season. The cause must be a change in body chemistry, whether hormonal or pheromonal we don’t know—but we do know how micro amounts of such substances will affect animal behavior, humans included. Now, this herd wasn’t mating and its antics were crazy even for that time of year. However, there were certain basic similarities. I wondered what new factor might have triggered the madness.”
He stopped for breath. “Go on!’” Eva urged.
Dan sought Ralph’s gaze. “Petroleum is complicated stuff,” he said. “Besides long-chain hydrocarbons, it contains all sorts of aromatics and the chemists alone know what else. In addition, your jet fuel probably has polymers or whatever, produced in the course of refining. My idea was that in among those molecules is one, or a set, that happens to resemble the terasaurian sex agent.” Mary drew a gasp. “Not your fault,” Dan added hastily. “Nobody could have known. But it does underline the necessity of learning everything we can about this planet, doesn’t it?”
The blond young man scowled. “You mean … wait a minute,” he said. “A few bulls drifted near our car, probably just curious. They got a whiff of unburned fuel dissipating in the exhaust; we’d left the motor idling as a precaution—what we thought was a precaution. That whiff was enough to make them charge, cutting us off from the car. Then, when the first tank was ruptured and fuel spilled out by the hundreds of liters, it drove the entire herd into a frenzy. Is that what you mean?”
Dan nodded again. “Correct. Though of course the total situation was wrong, unbalanced, for the poor beasts. The molecules involved must have similarities but no doubt aren’t identical with their natural gonad stimulator. Besides, it’s the wrong time of year and so forth. No wonder they ran
