Norman said； 〃Harry…〃
〃…I just want to know why you two are looking at me like that。 You're looking at me like I'm a criminal or something。〃
〃Don't get paranoid； Harry。〃
〃Huddling up here； whispering 。。。〃
〃We weren't whispering。〃
〃You were。〃 Harry looked around the room。 〃So it's two white people and one black person now； is that it？〃
〃Oh； Harry 。。。〃
〃I'm not stupid； you know。 Something's going on between you。 I can tell。〃
〃Harry；〃 Norman said； 〃nothing is going on。〃
And then they heard a low insistent beeping； from the munications console downstairs。 They exchanged glances； and went downstairs to look。
The console screen was slowly printing out letter groups。

〃Is that Jerry？〃 Norman asked。
〃I don't think so；〃 Harry said。 〃I don't think he would go back to code。〃
〃Is it a code？〃
〃I would say so； definitely。〃
〃Why is it so slow？〃 Beth said。 A new letter was added every few seconds in a steady； rhythmic way。
〃I don't know；〃 Harry said。 〃Where is it ing from？〃
Harry frowned。 〃I don't know； but the transmission speed is the most interesting characteristic。 The slowness。 Interesting。〃
＇＇276＇＇ Norman and Beth waited for him to figure it out。 Norman thought： How can we ever get along without Harry？ We need him。 He is both the most important intelligence down here； and the most dangerous。 But we need him。

〃Interesting；〃 Harry said。 〃The letters are ing about every five seconds。 So I think it's safe to say that we know where it's ing from。 Wisconsin。〃
Norman could not have been more surprised。 〃Wisconsin？〃
〃Yeah。 This is a Navy transmission。 It may or may not be directed to us； but it is ing from Wisconsin。〃
〃How do you know that？〃
〃Because that's the only place in the world it could be ing from；〃 Harry said。 〃You know about ELF？ No？ Well； it's like this。 You can send radio waves through the air； and； as you know； they travel pretty well。 But you can't send radio far through water。 Water is a bad medium； so you need an incredibly powerful signal to go even a short distance。〃
〃Yes 。。。〃
〃But the ability to penetrate is a function of wavelength。 An ordinary radio wave is short…shortwave radio； all of that。 The length of the waves are tiny； thousands or millions of little waves to an inch。 But you can also make ELF； extremely low…frequency waves； which are long…each individual wave is maybe twenty feet long。 And those waves； once generated； will go a very great distance； thousands of miles； through water； no problem。 The only trouble is that； since the waves are long； they're also slow。 That's why we're getting one character every five seconds。 The Navy needed a way to municate with their submarines underwater； so they built a big ELF antenna in Wisconsin to send these long waves。 And that's what we're getting。〃
〃And the code？〃
〃It must be a pression code…three…letter groupings which stand for a long section of predefined message。 So it won't take so long to send a message。 Because if you sent a plain text message； it would literally take hours。〃

The letters stopped。
〃Looks like that's it；〃 Harry said。
〃How do we translate it？〃 Beth said。
〃Assuming it's a Navy transmission；〃 Harry said； 〃we don't。〃
〃Maybe there's a codebook here somewhere；〃 Beth said。
〃Just hold on；〃 Harry said。
The screen shifted； translating groups one after another。
2340 HOURS 7…07 CHIEF CINCPAC TO BARNES DEEPHAB…8
〃It's a message to Barnes；〃 Harry said。 They watched as the other letter groups were translated。

〃Does that mean what I think it means？〃 Beth said。
〃Yeah；〃 Harry said。 〃The cavalry is on the way。〃
〃Hot damn！〃 Beth clapped her hands。
〃The storm must be calming down。 They've sent the surface ships and they'll be here in a little more than sixteen hours。〃
〃And autoset？〃
They had the answer immediately。 Every screen in the habitat flickered。 In the upper right corner of each appeared a small box with numbers： 16：20：00。 The numbers ran backward。
〃It's automatically counting down for us。〃
〃Is there some kind of countdown we're supposed to follow for leaving the habitat？〃 Beth said。
Norman watched the numbers。 They were rolling backward； just as they had on the submarine。 Then he said； 〃What about the submarine？〃
〃Who cares about the submarine；〃 Harry said。
〃I think we should keep it with us；〃 Beth said。 She checked her watch。 〃We have another four hours before it has to be reset。〃
〃Plenty of time。〃
＇＇278＇＇ 〃Yes。〃
Privately； Norman was trying to gauge whether they could survive for sixteen more hours。
Harry said； 〃Well； this is great news！ Why are you two so hangdog？〃
〃Just wondering if we'll make it；〃 Norman said。
〃Why shouldn't we make it？〃 Harry said。
〃Jerry might do something first；〃 Beth said。 Norman felt a burst of irritation with her。 Didn't she realize that by saying that； she was planting the idea in Harry's mind？
〃We can't survive another attack on the habitat；〃 Beth said。
Norman thought； Shut up； Beth。 You're making suggestions。
〃An attack on the habitat？〃 Harry said。
Quickly； Norman said； 〃Harry； I think you and I should talk to Jerry again。〃
〃Really？ Why？〃
〃I want to see if I can reason with him。〃
〃I don't know if you can；〃 Harry said。 〃Reason with him。〃
〃Let's try anyway；〃 Norman said； with a glance at Beth。 〃It's worth a try。〃
Norman knew he would not really be talking to Jerry。 He would be talking to a part of Harry。 An unconscious part； a shadow part。 How should he go about it？ What could he use？
He sat in front of the monitor screen； thinking； What do I know about Harry； really？ Harry； who had grown up in Philadelphia as a thin； introverted； painfully shy boy； a mathematical prodigy； his gifts denigrated by his friends and family。 Harry had said once that when he cared about mathematics； everybody else cared about slamdunking。 Even now； Harry hated all games； all sports。 As a young man he had been humiliated and neglected； and when he finally got proper recognition for his gifts； Norman suspected； it came too late。 The damage was already done。 Certainly it came too late to prevent the arrogant； braggart exterior。
＇＇279＇＇ I AM HERE。 DO NOT BE AFRAID。
〃Jerry。〃
YES NORMAN。
〃I have a request to make。〃
YOU MAY DO SO。
〃Jerry； many of our entities are gone； and our habitat is weakened。〃
I KNOW THIS。 MAKE YOUR REQUEST。
〃Would you please stop manifesting？〃
NO。
〃Why not？〃
I DO NOT WISH TO STOP。
Well； Norman thought； at least we got right down to it。 No wasting time。 〃Jerry； I know that you have been isolated for a long time； for many centuries； and that you have felt alone during all that time。 You have felt that nobody cared about you。 You have felt that nobody wanted to play with you； or shared your interests。〃
YES THIS IS TRUE。
〃And now at last you can manifest； and you are enjoying this。 You like to show us what you can do； to impress us。〃
THIS IS TRUE。
〃So that we will pay attention to you。〃
YES。 I LIKE IT。
〃And it works。 We do pay attention to you。〃
YES I KNOW IT。
〃But these manifestations
