〃Heavy ice；〃 Saunders intoned。 〃Still heavy ice。〃
Sluggishly the 〃Dolphin〃 continued to rise。 Next time in the control room； I promised myself； I wouldn't forget that bath towel。 Swanson said； 〃If we've overestimated the speed of the drift； there's going to be another bump； I'm afraid。〃 He turned to Rawlings； who was still repairing lights。 〃If I were you； I'd suspend operations for the present。 You may have to start all over again in a moment； and we don't carry all that number of spares aboard。〃
〃One hundred feet；〃 the diving officer said。 He didn't sound as unhappy as his face looked。
〃The water's clearing；〃 Hansen said suddenly。 〃Look。〃
The water had cleared； not dramatically so； but enough。 We could see the top corner of the sail clearly outlined on the TV screen。 And then； suddenly； we could see something else again； heavy； ugly ridged ice not a dozen feet above the sail。
Water flooded into the tanks。 The diving officer didn't have be to told what to do： we'd gone up like an express elevator the first time we'd hit a different water layer； and once like that was enough in the life of any submarine。
〃Ninety feet；〃 he reported。 〃Still rising。〃 More water flooded in； and then the sound died away。 〃She's holding。 Just under ninety feet。〃
〃Keep her there。〃 Swanson stared at the TV screen。 〃We're drifting clear and into the polynyaI hope。〃
〃Me too；〃 Hansen said。 〃There can't be more than a couple of feet between the top of the sail and that damned ugly stuff。〃
〃There isn't much room；〃 Swanson acknowledged。 〃Sanders？〃
〃Just a moment； sir。 The graph looks kinda funny No； we're clear。〃 He couldn't keep the excitement out of his voice。 〃Thin ice！〃
I looked at the screen。 He was right。 I could see the vertical edge of a wall of ice move slowly across the screen； exposing clear water above。
〃Gently； now； gently；〃 Swanson said。 〃And keep that camera on the ice wall at the side； then straight up； turn about。〃
The pumps began to throb again。 The ice wall； less than ten yards away； began to drift slowly down past us。
〃Eighty…five feet；〃 the diving officer reported。 〃Eighty。〃
〃No hurry；〃 Swanson said。 〃We're sheltered from that drift by now。〃
〃Seventy…five feet。〃 The pumps stopped； and water began to flood into the tanks。 〃Seventy。〃 The 〃Dolphin〃 was almost stopped now； drifting upward as gently as thistledown。 The camera switched upward； and we could see the top corner of the sail clearly outlined with a smooth ceiling of ice floating down to meet it。 More water gurgled into the tanks； the top of the sail met the ice with a barely perceptible bump； and the 〃Dolphin〃 came to rest。
〃Beautifully done；〃 Swanson said warmly to the diving officer。 〃Let's try giving that ice a nudge。 Are we slewing？〃
〃Bearing constant。〃
Swanson nodded。 The pumps hummed； poured out water； lightening ship； steadily increasing positive buoyancy； The ice stayed where it was。 More time passed； more water pumped out； and still nothing happened。 I said softly to Hansen； 〃Why doesn't he blow the main ballast？ You'd get a few hundred tons of positive buoyancy in next to no time； and even if that ice is forty inches thick； it couldn't survive all that pressure at a concentrated point。〃 …
〃Neither could the 〃Dolphin〃；〃 Hansen said grimly。 〃With a suddenly induced big positive buoyancy like that； once she broke through； she'd go up like a cork from a champagne bottle。 The pressure hull might take it； I don't know； but sure as little apples the rudder would be squashed as flat as a piece of tin。 Do you want to spend what little's left of your life traveling in steadily decreasing circles under the polar ice cap？〃
I didn't want to spend what little was left of my life in traveling in steadily decreasing circles under the ice cap； so I kept quiet。 I watched Swanson as he walked across to the diving stand and studied the banked dials in silence for some seconds。 I was beginning to bee a little apprehensive about what Swanson would do next。 I was beginning to realize； and not slowly； either； that he was a man who didn't give up very easily。
〃That's enough of that；〃 he said to the diving officer。 〃If we go through now with all this pressure behind us； we'll be airborne。 This ice is even thicker than we thought。 We've tried the long； steady shove and it hasn't worked。 A sharp tap is obviously what is needed。 Flood her down； but gently； to eighty feet or so。 A good sharp whiff of air into the ballast tanks； and we'll give our well…known imitation of a bull at a gate。〃
Whoever had installed the 240…ton air…conditioning unit in the 〃Dolphin〃 should have been prosecuted； it just wasn't working any more。 The air was very hot and stuffywhat little there was of it； that was。 I looked around cautiously and saw that everyone else appeared to be suffering from this same shortage of air； all except Swanson； who seemed to carry his own built…in oxygen cylinder around with him。 I hoped Swanson was keeping in mind the fact that the 〃Dolphin〃 cost 120 million dollars to build。 Hansen's narrowed eyes held a definite core of worry； and even the usually imperturbable Rawlings was rubbing a bristly blue chin with a hand the size and shape of a shovel。 In the deep silence after Swanson had finished speaking the scraping noise sounded unusually loud； then was lost in the noise of water flooding into the tanks。
We stared at the screen。 Water continued to pour into the tanks until we could see a gap appear between the top of the sail and the ice。 The pumps started up； slowly； to control the speed of descent。 On the screen； the cone of light thrown on to the underside of the ice by the floodlight grew fainter and larger as we dropped； then remained stationary； neither moving nor growing in size。 We had stopped。
〃Now；〃 said Swanson。 〃Before that current gets us again。〃
There came the hissing roar of pressed air under high pressure entering the ballast tanks。 The 〃Dolphin〃 started to move sluggishly upward while we watched the cone of light on the ice slowly narrow and brighten。
〃More air；〃 Swanson said。
We were rising faster now； closing the gap to the ice all too quickly for my liking。 Fifteen feet； twelve feet； ten feet。
〃More air；〃 Swanson said。
I braced myself； one hand on the plot； the other on an overhead grab bar。 On the screen； the ice was rushing down to meet us。 Suddenly the picture quivered and danced； the 〃Dolphin〃 shuddered； jarred； and echoed hollowly along its length； more lights went out； the picture came back on the screen； the sail was still lodged below the ice； then the 〃Dolphin〃 trembled and lurched and the deck pressed against our feet like an ascending elevator。 The sail on the TV vanished； nothing but opaque white taking its place。 The diving officer； his voice high with strain that had not yet found relief； called out； 〃Forty feet； forty feet。〃 We had broken through。
〃There you are； now；〃 Swanson said mildly。 〃All it needed was a little perseverance。〃 I looked at the short； plump figure； the round； good…humored face； and wondered for the hundredth time why the nerveless iron men of this world so very seldom look the part。
I let my pride have a holiday。 I took my handkerchief from my pocket； wiped my face； and said to Swanson； 〃Does this sort of thing go on all the time？〃
〃Fortunately； perhaps； no；〃 he smiled。 He turned to the diving officer。 〃We've got our foothold on this rock。 Let's make sure we have a good belay。〃
For a few seconds； more pressed air was bled into the tanks； then the diving officer said： 〃No chance of her dropping down now； Captain。〃
〃Up periscope。〃
Again the long； gleaming silver tube hissed up from its well。 Swanson didn't even bother folding down the hinged handles。 He peered briefly into the eyepiece； then straightened。 〃Down periscope。〃
〃Pretty cold up top？〃 Hansen… asked。
Swanson nodded。 〃Water on the lens must have frozen solid as soon as it hit that air。 Can't see a thing。〃 He turned to the diving officer。 〃Steady at forty？〃
〃Guaranteed。 And all the buoyancy we'll ever want。〃
〃Fair enough。〃 Swanson looked at the quartermaster； who was shrugging his way into a heavy sheepskin coat。 〃How about a little fresh air； Ellis？〃
〃Right away； sir。〃 Ellis buttoned his coat and added： 〃Might take some time。〃
〃I don't think so；〃 Swanson said。 〃You may find the bridge and hatchways jammed with broken ice but I doubt it。 My guess is that that ice is so thick that it will have fractured into very large sections and fallen outside clear of the bridge。〃
I felt my ears pop with the sudden pressure change as the hatch swung up and open and snapped back against its standing latch。 Another； more distant sound as the second hatch cover locked open； and then we heard Ellis on the voice tube。
〃All clear up top。〃
〃Raise the antennae；〃 Swanson said。 〃John； have them start transmitting and keep transmitting until their fingers fall off。 Here we are and here we stayuntil we raise Drift Ice Station Zebra。〃
〃If there's anyone left alive there；〃 I said。
〃There's that； of course；〃 Swanson said。 He couldn't look at me。 〃There's always that。〃

This； I thought； death's dreadful conception of a dreadful world； must have been what had chilled the hearts and souls of our far…off Nordic ancestors when life's last tide slowly ebbed and they had tortured their failing minds with fearful imaginings of a bleak and bitter hell of eternal cold。 But it had been all right for the old boys； all they had to do was imagine it； we had to experience the reality of it； and I bad no doubt at all in my mind as to which was easier。 The latter…day Eastern conception of hell was altogether more fortable； at least a man could keep reasonably warm there。
One thing sure； nobody could keep reasonably warm where Rawlings and I were； standing a half…hour watch on the bridge of the 〃Dolphin〃 and slowly freezing solid。 It had been my own fault entirely that our teeth were chattering like frenzied castanets。 Half an hour after the radio room had started transmitting on Drift Ice Station Zebra's wave length and all without the slightest whisper by way of reply or acknowledgment； I had suggested to mander Swanson that Zebra might possibly be able to hear us without having sufficient power to send a reply but that they might just conceivably let us have an acknowledgment some other way。 I'd pointed out that drift stations habitually carried rocketsthe only way to guide home any lost members of the party if radio munication broke downand radio sondes and rockoons。 The sondes were …radio…carrying balloons that could rise to a height of twenty miles to gather weather information； the rockoons； radio rockets fired from balloons； could rise even higher。 On a moonlit night such as this； those balloons； if released； would be visible at least twenty miles away： if flares were attached to them； at twice that distance。 Swanson had seen my point； called for volunteers for the first watch； and in the circumstances I hadn't had much choice。 Rawlings bad offered to acpany me。
It was a landscapeif such a bleak； barren； and； featureless desolation could be called a landscapefrom another and ancient world； weird and strange and oddly frightening。 There were no clouds in the sky； but there were no stars； either： this I could not understand。 Low on the southern horizon a milky； misty moon shed its mysterious light over the dark lifelessness of the polar ice cap。 Dark； not white。 One would have expected moonlit ice to shine and sparkle and glitter with the light of a million crystal chandeliers： but it was dark。 The moon was so low in the sky that the dominating color on the ice cap came from the blackness of the long shadows cast by the fantastically ridged and hummocked ice； and where the moon did strike directly； the ice had been so scoured and abraded by the assaults of a thousand ice storms that it had lost almost all its ability to reflect light of any kind。
This ridged and hummocked ice cap had a strange quality of elusiveness； of impermanence； of evanescence： one moment there； definitively hard and harsh and repellent in its coldly contrasting blacks and whites； the next； ghost…like； blurring coalescing and finally vanishing like a shimm
