Sunrise, after the five and a half hours of darkness which prevailed at this season, found both men awake, though not entirely refreshed. Rodin, owing to his brief residence on Hekla, was in rather better condition than Vickers, but even he was beginning to feel and show the effects of the excess gravity. Both men ate an enormous breakfast — Vickers’ stores were far from exhausted — and then the “diplomat” led the way out of the ship, purposefully toward the great entrance in the rock.
“If I don’t get in this time, I think I’ll give it up as a bad job,” he remarked as they approached the opening. “I’m beginning to think Deg is a little too smooth for me. I wish I were more certain of what cooled him so toward us; my present idea is just a working hypothesis, and goodness knows when it may stop working.”
The men passed into the shadowy hangar, in which Vickers had never yet seen an aircraft. No one was there; the tunnels opening into the great cavern yawned dimly lighted and empty. Vickers led the way toward the elevator, without stopping to wonder where the Heklans might be. He knew the natives would meet them before they got far.
He was right. As they turned the last corner, bringing them in sight of the elevator, a Heklan stepped from the cage. Vickers was not sure whether or not it was one of the individuals whom he had already encountered — his comparative isolation with Deg while he was learning the Heklan language had given him no opportunity to study facial or other differences between members of that race — but this specimen was far too tall to be Deg himself. His eyes were almost on a level with those of the Earthmen, while his general build was in normal Heklan proportion. He must have weighed, on Hekla, between four and five hundred pounds.
The tremendous native listened politely to Vickers’ request to see Serrnak Deg, and nodded when the man finished speaking.
“I was coming to see you,” he said. “Deg has asked me to act as your guide. He will be glad to see you whenever you particularly wish it, but routine duties of his position, which he has been rather neglecting for the past few months, prevent him from spending all his time with you from now on. He asks me to apologize for any seeming discourtesy, but I am sure you understand his difficulties. In what way can I help you now?”
“My friend is a meteorologist, and would be interested in seeing the integration laboratory Deg showed me, as well as your observing apparatus. I understand perfectly why Deg cannot be with us, and I thank you for granting your time. Perhaps if we went first to the integration laboratory, and you explained your weather maps and their symbols to Rodin, he could comprehend the rest of your system more easily. He has been eager to see that laboratory ever since I described it to him. Does that meet with your approval?” Vickers had ideas of his own about the assignment of this enormous individual as their host, but determined to make the best of the situation.
“Whatever you wish,” returned the guide. “My name, by the way, is Marn Trangero — either name is acceptable as a form of address, as you probably gathered from Deg. We will go up to the integration room, then, if you are ready; as a matter of fact, Deg is probably there himself, just now, so if there is something you particularly wished to discuss with him, you will have a chance to do so.”
Vickers nodded understanding as they entered the dimly lit elevator. The Heklan pressed the button — Vickers examined carefully the faint character beside it as he did so — and they slid gently upward.
The laboratory was as Vickers remembered it; the globes, the computing machines, the operating personnel. The big central machine was active this time, with the four operators in their seats on each side. Marn pointed out one of these individuals.
“Deg is here, as I thought,” he said. “Did you particularly wish to speak to him?”
“Not if he is busy,” replied Vickers. “Could you explain these devices to us? I will translate to Rodin as well as I can, though you will probably have to explain most of your scientific terms with simpler words. What is the connection between those globes and the computers beneath them?”
“The globes are weather maps. The computers handle observed values of air pressure, temperature, humidity, and similar factors, setting them up as isopleths on the globes and calculating their individual trends. Each of the machines handles one such variable and its individual characteristics. The results of these computations are fed to the intermediate machines, and finally to the master computer, which is supposed to give a complete weather picture. All the factors at once could be shown on the main screen, but it would make a very confusing picture. The trouble, of course, is that each factor is dependent on all the others, and the integration has to be fed back to the individual machines to correct their values for each few minutes of a prediction. It is really a very clumsy system: a single computer capable of tracking all the variables at once would be far speedier and more convenient. Such a machine is being designed at one of our research centers, but it is so far much too bulky, complex, and tricky for an outpost such as this. I should like a chance at it myself, as you can well imagine.”
Vickers could imagine; he recalled scientist friends of his own who would give ten years of their lives for six months’ time at some particular laboratory, or machine, or in some fellow worker’s company. He relayed the explanation to Rodin, who nodded in understanding and examined very closely each of the globes in turn. The meteorologist then spent several minutes carefully observing the operation of the keyboards of several of the machines. He finally asked for an illustration of the system’s accuracy; Vickers relayed the question to Marn.
“Since I am not acquainted with your own progress in this field, I hesitate to call our work accurate,” was the reply. “In meteorology, it is difficult to define accuracy, in any case. If you like, however, I can translate the machine’s prediction of the next few hours’ weather. From a cursory glance, it seems to me that it will be different enough from the local norm to afford you a fair check on our methods. If you will wait a few moments, I will interpret the records from the machine.”
He left them, while Vickers explained his proposition to Rodin. The meteorologist approved strongly, and they waited expectantly for the Heklan’s return. He was gone only a few minutes.
“You know,” he began as he approached the men, “that this station is at the coast of a large continental area. You have undoubtedly noticed the stiff sea breeze which forms a normal part of our weather at this season. It is a direct cause of the cumulus cloud which builds up above this hill each day.
“Since your arrival, Vickers, the weather has departed only very slightly from the norm. Now, however, a weak warm front has developed to the southwest, and is moving in this direction. Its first symptoms, high thin clouds, will arrive about midday. They will lower rapidly, reaching the level of the station three and a half hours later, and precipitation will occur almost immediately after that. Winds will continue rising until the rain starts; thereafter they will decrease, and shift from south to west. I could give you numerical values for wind velocity, air pressure, temperature, and so forth; but they would have to be translated into your units, and I don’t believe either of us can do that. All clouds should disappear before sunset, including the cumulus head one usually sees over this point. Deg has just warned the gardeners on the lower slopes of the front, I see. It might be a good idea to move your ship into the hangar — though you know the strength of your own creations better than I; use your judgment. Winds sometimes become rather violent here at the hilltop.”
“The ship is a pretty solid piece of machinery, and we can anchor to the mountain if necessary,” replied Vickers. “Why do you warn the gardeners, if this is to be a weak front? And what is the nature of the gardens I saw on my drive with Deg a few days ago?”
“The plants nourish a fermenting protozoan in their roots, and store alcohol in their stems and spore pods. The longer they grow, the higher the alcoholic content; but a strong wind ruptures the pods and frees the alcohol. Consequently, we try to harvest just before a wind. The local garde
ns are small; we simply produce enough to power the station. I believe there are efforts under way to modify the protozoans to produce better fuels, but if they have met with success we have yet to receive the benefits. Your arrival, of course, may obviate the need for further work along such lines; you certainly didn’t cross interstellar space on combustion engines.”
Vickers nodded absently at this remark, as he translated the gist of the forecast to Rodin. The latter listened carefully, making certain of details that seemed unimportant to his companion, and finally asked to see the observing portions of the station.
Trangero agreed instantly to this request, and turned back to the elevator. Once again they traveled upward, emerging this time into a small chamber from which half a dozen doors opened. The Heklan led them through one of these.
They found themselves on a flat area, only a few yards square, and obviously artificial, located only a dozen yards below the actual peak of Observatory Hill. A metal ladder led to the peak itself, which was topped by a slender but solid-looking tower. Part of the platform was walled with stone, and the rest guarded by a metal rail. Several instruments were mounted on the rail itself, and some larger devices on the rock just outside. The tower was topped by a tiny vane. Marn showed the men each of the instruments in turn, vaulting the rail easily to demonstrate those beyond it. Neither of the human beings enjoyed going outside its protection; the rock was smooth, and after the first few feet sloped very steeply toward the landing ramp sixty yards below. The ship was just visible from the safe side of the railing.
The instruments seemed normal enough to Vickers, and even Rodin had little to say about them. There were thermometers, precipitation gauges, and hygrometers, all connected electrically to recorders in the laboratories below. The vane on the tower was similarly connected to record wind direction, and it contained a pivot head to measure velocity. The few other devices were slight variants of standard — to Rodin— equipment; and the meteorologist felt rather let down at the end of the tour. He felt fairly surely that the Heklans, in spite of their efficient world net, were no further advanced in meteorology than any Federation planet; but he decided not to voice the opinion until after checking a fair number of their predictions. He awaited the approaching storm with interest. He glanced occasionally to the southwest while they were at the summit, but the omnipresent haze of Hekla’s dense atmosphere hid the horizon; and no signs of the approaching weather appeared before Marn shepherded the men back to the elevator. The other parts of the station, which the Heklan insisted on showing them, were connected with the maintenance of the place rather than with its primary function. The power plant was on the same level as the hangar; it consisted of six surprisingly small electric generators driven by equally diminutive internal-combustion engines, which, according to Marn, burned the alcohol produced by the gardens on the slopes of the hill. These units powered the elevator, supplied heat and light sufficient for the Heklans’ small needs, and operated the numerous items of electrical equipment.
They spent fully three hours inspecting the station; if Marn had been ordered to tire the men out on nonessential details, he was doing splendidly. Rodin lost interest after leaving the roof. Vickers kept up a good front, but eventually even he had to call a halt for rest. Perhaps his fatigue can be blamed for causing him to forget an issue he had planned to force — the roomfull of electric equipment from which he had been diverted two days before, and which Marn had skipped by accident or design. Vickers did forget it, made his excuses to the Heklan, and was back in the ship before he recalled the matter. By that time he was nearly asleep, settled back in one of the chairs in the ship’s library.
He slept four or five hours. Rodin remained awake for some time, but was asleep when Vickers awoke; by the time both had finished sleeping, eating, and talking over the morning’s events, the sun was well up in the sky. So far the weather appeared normal, though Vickers, who had been around long enough to be used to it, thought the breeze was less strong and the cumulus banner less well developed than usual. Marn’s weather was not jumping the gun, at any rate.
It was not late, either. A few minutes before noon — as nearly as they could judge the time — Rodin detected the first wisps of cirrus, high above. They must have been above the horizon for some time, invisible in the haze. As the men were on the landward — and consequently the leeward — side of the hill, the change in wind direction was not noticeable for some time; but its strength mounted rapidly as the clouds thickened and dropped closer to the hilltop. Rodin, stepping outside the ship for a moment, was taken by surprise and knocked over by a gust that eddied around the rock shoulder. He got to his feet immediately, bracing himself against the metal hull, and looked around. Toward the west, the haze had thickened so that it was now impossible to make out details on the plateau inland. Two or three thousand feet overhead, the scud raced along parallel to the coast. On Earth, under similar circumstances, the cloud layers would have been gray; but the fainter, red light of R Coronae here gave them an indescribably eerie pinkish color. All traces of the sky had by now disappeared. Rodin could actually feel in his ears the change in air pressure as other eddies swirled by him. It was still cold; the frontal surface, of course, had not yet come down to his level.
He returned to the control room, thinking. If Vickers had translated correctly, Marn had forecast a weak front; and this outside weather could already be called violent without stretching facts. Either the Heklan prediction was inaccurate, or Rodin would have to revise his ideas of what constituted a violent storm. In three months of residence, Vickers had noticed nothing extraordinary about the weather; and it seemed probable that if Heklan atmospheric phenomena were built to a different scale, the fact would have become apparent in that time. Rodin, thinking the matter over, adopted his usual course of withholding an opinion.
The wind increased, and as the clouds thickened the pinkish light faded into total darkness. Rain began to beat against the metal hull, and the light from the control room window penetrated only a few feet into the murk. The clouds had reached the level of the hilltop. Rodin cautiously opened the outer air lock door again; fortunately it was power-operated, or he would have been unable to close it. Several times the ship shuddered from end to end under the blast. Vickers charged the anchoring fields along the keel after the first tremor, but evidently the rock itself was quivering; an occasional vibration could still be felt during the heaviest gusts of wind. There would be more shattered rock on the terraces when the weather cleared.
The time passed slowly. Rodin kept watching the clock, trying to figure the time of Heklan day on the twenty-four-hour dial in order to keep check on Marn’s prediction. Vickers read and thought, while the storm reached and passed its height. Twice the men were disturbed by an odd, crackling sound, and looked up to see ghostly fingers of fire crawling about the transparent ports. The meteorologist blinked at the sight; he was accustomed to electrical activity in storms with strong vertical development, but to get it with strictly horizontal winds somewhat surprised him. He wondered what velocity the wind must have reached to ionize the raindrops. Vickers felt thankful for the metallic construction of the ship.
Slowly the shuddering diminished, the howling of the wind died, and the dense fog grew once more pinkly luminous. The men ventured outside again, finding that the wind was still strong, but no longer savage. The fog was thinning, and the wind, true to prediction, was blowing from inland, bringing even to this height odors from the vast plains and hills of the great continent.
Rodin stood looking, as the view cleared, at the reappearing sun and the vaguely visible landscape, sniffing the odd smells, and gradually acquiring a puzzled expression. Vickers noted it, and started to ask the nature of the trouble; but he changed his mind, knowing that he was unlikely to get an answer, and went into the ship instead. He found himself shivering, as usual on Hekla, so he picked up the jacket he had discarded after the morning’s inspection tour. Attired in this, he went outside again.
“Let’s go back to the station,” he said. “I want to pick a bone with Marn, or with Deg, if necessary. There are one or two things going on that I don’t fully understand. These friends of yours don’t have to sleep half the day like a couple of poor Earthmen, do they?”
“They should still be active,” Vickers replied, looking at the sun. “It’s a couple of hours till sundown, if what I can see of the sun and what I can guess of the horizon’s position aren’t combining to fool me. These fellows sleep for a few hours each night from habit, and I guess they can do without that for quite a time. There should be no trouble in finding Marn, if he’s supposed to be looking after us.”
There was no trouble. They did not meet Trangero the moment they entered the station, but the first Heklan who saw them made it his business to deliver them into the proper custody, and led them to an office on a floor two or three levels below the integration room. Marn raised his enormous bulk from behind a desk as they entered. Vickers thought fleetingly of the curious similarity between human and Heklan forms of courtesy; then he turned his attention to the task of interpreting for the two weather men. Rodin opened the conversation with a question.
“Did I understand correctly that you were basing the prediction for the last few hours upon the passage of a warm front?”
“That is correct. I was several minutes off on the time of passage; but that is not included explicitly in the machine solutions that are recorded, and I did not occupy a machine with the detailed problem.”
