It is well to approach all miracles and wonders by gradual stages or degrees, and we can do this by examining another aspect of the glassy seascape of which the Mouser also might well have been thinking — but wasn't.
Although untroubled by swell, wavelet or faintest ripple or quiver, the Inner Sea around the sloop was not perfectly flat. Here and there, scatteredly, it was dimpled with small depressions about the size and shape of shallow saucers, as if giant invisible featherweight water-beetles were standing about on it — though the dimples were not arranged in any six-legged or four-legged or even tripod patterns. Moreover, a slim stalk of air seemed to go down from the center of each dimple for an indefinite distance into the water, quite like the tiny whirlpool that sometimes forms when the turquoise plug is pulled in the brimful golden bathtub of the Queen of the East (or the drain unstoppered in a bathtub of any humbler material belonging to any lowlier person) — except that there was no whirling of water in this case, and the air stalks were not twisted and knotted but straight, as though scores of slim-bladed rapiers with guards like shallow saucers but all as invisible as air had been plunged at random into the motionless waters around the Black Treasurer. Or as though a sparse forest of invisible lily pads with straight invisible stems had sprung up around the sloop.
Imagine such an air-stalked dimple magnified so that the saucer was not a palm's breadth but a good spearcast across and the rodlike sword-straight stalk not a fingernail's width but a good four feet, imagine the sloop slid prow-foremost down into that shallow depression but stopping just short of the center and floating motionless there, imagine the bowsprit of the slightly tilted ship projecting over the exact center of the central tube or well of air, imagine a small, stalwart, nut-brown man in a gray loincloth lying along the bowsprit, his feet braced against the foredeck rails, and looking straight down the tube… and you have the Gray Mouser's situation exactly!
To be in the Mouser's situation and peering down the tube was very fascinating indeed, an experience calculated to drive other thoughts out of any man's mind — or even any woman's! The water here, a bowshot from the creamy rock-wall, was green, remarkably clear, but too deep to allow a view of the bottom — soundings taken yesterday had shown it to vary between six score and seven score feet. Through this water the well-size tube went down as perfectly circular and as smooth as if it were walled with glass; and indeed the Mouser would have believed that it was so walled — that the water immediately around it had been somehow frozen or hardened without altering in transparency — except that at the slightest noise, such as the Mouser's coughing, little quiverings would run up and down it in the form of a series of ring-shaped waves.
What power prevented the tremendous weight of the sea from collapsing the tube in an instant, the Mouser could not begin to imagine.
Yet it was endlessly fascinating to peer down it. Sunlight transmitted through the sea water illuminated it to a considerable depth brightly if greenishly, and the circular wall played odd tricks with distance. For instance, at this moment the Mouser, peering down slantwise through the side of the tube, saw a thick fish as long as his arm swimming around it and nosing up to it. The shape of the fish was very familiar yet he could not at once name it. Then thrusting his head out to one side and peering down at the same fish through the clear water alongside the tube, he saw that the fish was three times the length of his body — in fact, a shark. The Mouser shivered and told himself that the curved wall of the tube must act like the reducing lenses used by a few artists in Lankhmar.
On the whole, though, the Mouser might well have decided in the end that the vertical tunnel in the water was an illusion born of sun-glare and suggestion and have put on the ice-goggles and stuffed his ears with wax against any more siren-singing and then perhaps swigged at the forbidden brandy and gone to sleep, except for certain other circumstances footing the whole affair much more firmly in reality. For instance, there was a knotted rope securely tied to the bowsprit and hanging down the center of the tube, and this rope creaked from time to time with the weight on it, and also there were threads of black smoke coming out of the watery hole (these were what made the Mouser cough), and last but not least there was a torch burning redly far down in the hole — so far down its flame looked no bigger than a candle's — and just beside the flame, somewhat obscured by its smoke and much tinied by distance, was the upward-peering face of Fafhrd!
The Mouser was inclined to take on faith the reality of anything Fafhrd got mixed up with, certainly anything that Fafhrd got physically into — the near-seven-foot Northerner was much too huge a hulk of solid matter to be picturable as strolling arm-in-arm with illusions.
The events leading up to the reality-footing facts of the rope, the smoke, and Fafhrd down the air-well had been quite simple. At dawn the sloop had begun to drift mysteriously among the water dimples, there being no perceptible wind or current. Shortly afterward it had bumped over the lip of the large saucer-shaped depression and slid to its present position with a little rush and then frozen there, as though the sloop's bowsprit and the hole were mutually desirous magnetic poles coupling together. Thereafter, while the Mouser had watched with eyes goggling and teeth a-chatter, Fafhrd had sighted down the hole, grunted with stolid satisfaction, slung the knotted rope down it, and then proceeded to array himself, seemingly with both war and love in mind — pomading his bushy hair and beard, perfuming his hairy chest and armpits, putting on a blue silk tunic under the gleaming one of otterskin and all his silver-plated necklaces, armbands, brooches and rings as well, but also strapping longsword and ax to his sides and lacing on his spiked boots. Then he had lit a long thin torch of resinous pine in the galley firebox, and when it was flaming bravely he had, despite the Mouser's solicitous cries and tugging protests, gone out on the bowsprit and lowered himself into the hole, using thumb and forefinger of his right hand to grip the torch and the other three fingers of that hand, along with his left hand, to grip the rope. Only then had he spoken, calling on the Mouser to make ready and follow him if the Mouser were more hot-blooded man than cold-blooded lizard.
The Mouser had made ready to the extent of stripping off most of his clothing — it had occurred to him it would be necessary to dive for Fafhrd when the hole became aware of its own impossibility and collapsed — and he had fetched to the foredeck his own sword Scalpel and dagger Cat's Claw in their case of oiled sealskin with the notion they might be needed against sharks. Thereafter he had simply poised on the bowsprit, as we have seen, observing Fafhrd's slow descent and letting the fascination of it all take hold of him.
At last he dipped his head and called softly down the hole, “Fafhrd, have you reached bottom yet?” frowning at the ring-shaped ripples even this gentle calling sent traveling down the hole and up again by reflection.
“What did you say?"
Fafhrd's answering bellow, concentrated by the tube and coming out of it like a solid projectile, almost blasted the Mouser off the bowsprit. Far more terrifying, the ring-ripples accompanying the bellow were so huge they almost seemed to close off the tube — narrowing it from four to two or three feet at any rate and dashing a spray of drops up into the Mouser's face as they reached the surface, lifting the rim upward as if the water were elastic, and then were reflected down the tube again.
The Mouser closed his eyes in a wince of horror, but when he opened them the hole was still there, and the giant ring-ripples were beginning to abate.
Only a shade more loudly than the first time, but much more poignantly, the Mouser called down, “Fafhrd, don't do that again!"
