There were sighs of relief from the financiers and a few questions to clear up certain points so that when Gus continued he had the informed and knowledgeable attention of his small audience.
“As has been demonstrated we now have our means of transportation and the preforming technique to lay the tunnel. The final step, before detailed surveying and construction begins, is the selection of the route to be followed. Because of the complex nature of the ocean’s floor, great care must be taken at this point, for the bottom of the Atlantic is no sandy lagoon that may be slashed directly across. Hardly! What we have here is a varied landscape more complex and drastic than the one we know on the drier surfaces of our globe. There are, of course, the abyssal plains that form the bottom, lying at an average depth of sixteen thousand feet below the ocean’s surface, but other features must be taken into consideration.
“Down the center of the ocean runs the Mid-Atlantic Ridge, a great mountain chain that is in reality a double row of mountains with the gorge of the Rift Valley between them. These mountain ranges and the Rift Valley are crossed at right angles by immense canyons called fracture zones that resemble wrinkles in the Earth’s hide. Other features also concern us, the Mid-Ocean Canyon, like an underwater riverbed on the ocean’s floor, seamounts and islands and trenches—that is, extraordinarily deep gulfs—such as this one, on the map here, that is over five miles in depth.
“And there are more factors to consider, underwater earthquakes and vulcanism which are concentrated in specific areas for the most part, the very high temperatures of the sea bottom near the Rift Valley as well as the fact that the sea bottom here is moving as the continents drift apart at the rate of about two inches a year. It appears, and the geologists confirm the suspicion, that hew matter rises from the Earth’s interior in the Rift Valley and spreads outwards at that steady rate. All problems, gentlemen, but none of them problems that cannot be surmounted.
“You will note the proposed route on this map which avoids these enumerated obstacles. If we begin here at Point 200 on the edge of the Continental Shelf, our tunnel proceeds roughly north northwest along the fracture zone we call 41-G that join the end of the Mid-Atlantic Ridge and the offset Reykjanes Ridge south of Iceland. By doing this we avoid the peril of crossing the Rift Valley which ceases to exist at this point. Now, further west, we emerge from the fracture zone and turn south, skirting the Mid-Ocean Canyon and swinging around the heights of the Milne Seamount until we reach the Sohm Abyssal Plain. At this point the tunnel will turn almost due north to rise up the Laurentian Cone to meet the tunnel already laid on the Continental Shelf at the Grand Banks Station. Now this route might be said to have a few faults.”
There was a rumble like a distant storm from Sir Isambard’s direction that Gus chose to ignore as he continued.
“Since the ocean bed is so warm in the fracture zone special tunnel sections will be laid on the bed itself, not in a trench, and constructed in such a manner that water will circulate through cavities in them to keep them cool. However the major criticism might be that, in order to avoid all the geological details, the tunnel will be twice as long as it would be if it went in a direct manner, therefore twice as costly.”
“Good God, man,” Sir Isambard exploded. “We have been over this before and you know we can’t go directly across the infernal ocean. So what are you suggesting?”
There was a hushed silence as Gus took a sheet of paper from his pocket and unfolded it, gulls could be heard crying outside and the strains of the orchestra playing in the distance, but all was listening quiet on the balcony.
“That is just what I am suggesting,” said Gus, with a positive sure-ness. “And I intend to show you how. I propose that the tunnel go due south from Point 200, over the flat bed of the Biscay Abyssal Plain to a base in the archipelago of the Azores, where it will meet the other leg of the tunnel that has come almost due east from the Grand Banks along the Oceanographer Fracture Zone. This route is less than half the length of the one under consideration now and, in addition, will provide an unexpected benefit. Cargo can be unloaded in the Azores base to be loaded on ships for Africa and the Continent, thereby shortening the voyage greatly. Plus the fact that another leg of the tunnel can eventually be considered from the Azores to Spain that will make a train connection between the Continent and the Americas. If this is done the results will be simply amazing.
“It will then be possible for a passenger to board a train at the Pacific port of Provideniya at the end of the Trans-Siberian Railroad and thence to proceed by train across Siberia, Russia and Europe, under the Atlantic, across America and connect with the Trans-Canada Railroad to Alaska there, to finish his journey once more on the shores of the Pacific. After a journey around at least ninety-nine percent of the Earth’s circumference at this point.”
At this juncture there were shouted questions and eager enthusiasm for more information about this novel idea until Sir Isambard hammered with his fist for silence.
“A mad dream, nothing more. Or rather it would be possible were it not for the aforementioned Mid-Atlantic Ridge with the Rift Valley which, I believe, is at least one mile wide and a number of miles deep at this point. It cannot be crossed. The plan is discarded.”
“Not so. The valley can be crossed and I have the plan for that procedure in my hand. It will be crossed, gentlemen, by an underwater bridge.”
Into the following silence Sir Isambard’s snort of contempt burst like a trumpet peal. “Nonsense, sir! Poppycock and nonsense! A bridge cannot be built a mile long that will support the weight of the tunnel sections at this depth.”
“You are correct, sir, it cannot. That is why this bridge will have negative buoyancy, a thing our tunnel sections have in any case until we weight them down, so it will float over the canyon, secured in place by heavy cables.”
This time the silence was absolute as Gus snapped open his plan and put it before them, explaining how the bridge would be made and how, since it floated, it could absorb the two-inch-a-year movement of its opposite ends, and all the other details of his new proposal. For every question asked he had an answer and it soon became obvious that, unless unknown factors were thought up, this plan was far superior to the earlier one in every way.
Long before this became clear to the others it was realized by Sir Isambard who parted the table and stood, arms folded, staring out at the setting sun. When the others had exhausted their words and enthusiasm and stopped for breath he turned and fixed Gus with a gaze the coldness of which outdid the most frigid blast of arctic night.
“You have done this deliberately, Washington, produced your plan to supersede mine in an attempt to obtain some gain.”
“Never sir! You have my word…”
“There is no doubt this design, or a variation of it, will be adopted,” the redoubtable man continued, unheeding of the interruption. “The tunnel will be built to the Azores and you will get the credit I am sure. Since I put the good of the tunnel above my own ambition I will continue working as I have done in the past. But for you, sir, personally, sir, I have little regard. Please be informed that you will no longer be a welcome guest in my house.”
Gus was nodding even before the other had finished, for it had been? foreordained.
“I was sure of that from the beginning,” said he, a weight of unspoken feelings in these simple words. “I have nothing but good feelings for you, sir, nor do I intend to do you injury in any way. I wish that you would believe me when I say that I have put the good of the tunnel ahead of any personal advancement for myself. Therefore, in the light of your remarks, I have no choice other than to resign from my position in the Transatlantic Tunnel Company and leave their employ. If my presence is a disconcerting one and interferes with the completion of this great work, then I will remove that presence.”
