cannot expect free radio communication with her. For that reason alone she must return safely or the whole value of the operation will be lost. Apart from that, she is the only long-range vessel left at our disposal for communication with South America and with South Africa. With these considerations in mind I have made fairly drastic alterations to the cruise that we discussed at our last meeting. The investigation of the Panama Canal has been struck out. San Diego and San Francisco also have been struck out. All these are on account of minefields. Commander Towers, will you tell us shortly how you stand in regard to minefields?'
Dwight gave the conference a short dissertation on the mines and on his lack of knowledge. 'Seattle is open to us, and the whole of Puget Sound,' he said. 'Also Pearl Harbor. I'd say there wouldn't be much danger from mines up around the Gulf of Alaska on account of the ice movements. The ice constitutes a problem in those latitudes, and the Scorpion's no icebreaker. Still, in my opinion we can feel our way up there without unduly hazarding the ship. If we just can't make it all the way to latitude sixty, well, we'll have done our best. I'd say we probably can do most of what you want.'
They turned to a discussion of the radio signals still coming from somewhere in the vicinity of Seattle. Sir Phillip Goodall, the director of C.S.I.R.O., produced a synopsis of the messages monitored since the war. 'These signals are mostly incomprehensible,' he said. 'They occur at random intervals, more frequently in the winter than the summer. The frequency is 4.92 megacycles.' The radio officer made a note upon the paper in front of him. 'One hundred and sixty-nine transmissions have been monitored. Of these, three contained recognizable code groups, seven groups in all. Two contained words in clear, in English, one word in each. The groups were undecipherable; I have them here if anyone wants to see them. The words were waters and connect.'
Sir David Hartman asked, 'How many hours' transmission, in all, were monitored?'
'About a hundred and six hours.'
'And in that time only two words have come through in clear? The rest is gibberish?'
'That is correct.'
The admiral said, 'I don't think the words can be significant. It's probably a fortuitous transmission. After all, if an infinite number of monkeys start playing with an infinite number of typewriters, one of them will write a play of Shakespeare. The real point to be investigated is this-how are these transmissions taking place at all? It seems certain that there is electrical power available there still. There may be human agency behind that power. It's not very likely, but it could be so.'
Lieutenant Sunderstrom leaned towards his captain and spoke in a low tone. Dwight said aloud, 'Mr. Sunderstrom knows the radio installations in that district.'
The lieutenant said diffidently, 'I wouldn't say that I know all of them. I attended a short course on naval communications at Santa Maria Island about five years back. One of the frequencies that was used there was 4.92 kilocycles.'
The admiral asked, 'Where is Santa Maria Island?'
'That one is just near Bremerton in Puget Sound, sir. There's several others on the Coast. This one is the main navy communications school for that area.'
Commander Towers unrolled a chart, and pointed to the island with his finger. 'Here it is, sir. It connects with the mainland by a bridge to this place Manchester right next to Clam Bay.'
The admiral asked, 'What would be the range of the station on Santa Maria Island?'
The lieutenant said, 'I wouldn't know for certain, but I guess it's global.'
'Does it look like a global station? Very high aerials?'
'Oh, yes, sir. The antennas there are quite a sight. I think it's a part of the regular communication system covering the Pacific area, but I don't know that for sure. I only attended the communications school.'
'You never communicated with the station direct, from any ship that you were serving in?'
'No, sir. We operated on a different set of frequencies.'
They discussed the techniques of radio for a time. 'If it turns out to be Santa Maria,' Dwight said at last, 'I'd say we can investigate it without difficulty.' He glanced at the chart that he had studied before, to confirm his studies. 'There's forty feet of water right close up to it,' he said. 'Maybe we could even lie alongside a wharf. In any case, we've got the rubber boat. If the radiation level is anywhere near reasonable, we can put an officer on shore for a while, in the protective suit, of course.'
The lieutenant said, 'I'd be glad to volunteer for that. I guess I know the way around that installation pretty well.'
They left it so, and turned to a consideration of the Jorgensen effect, and the scientific observations that were needed to prove or to disprove it.
Dwight met Moira Davidson for lunch after the conference. She had picked a small restaurant in the city for their meeting and he was there before her. She came to him bearing an attache case.
He greeted her and offered her a drink before lunch. She elected for a brandy and soda, and he ordered it. 'Double?' he inquired, as the waiter stood by.
'Single,' she said. He nodded to the waiter without comment. He glanced at the attache case. 'Been shopping?'
'Shopping!' she said indignantly. 'Me-full of virtue!'
'I'm sorry,' he replied. 'You're going someplace?'
'No,' she said, enjoying his curiosity. 'I'll give you three guesses what's in it.'
'Brandy,' he suggested.
'No. I carry that inside me.'
He thought for a moment. 'A carving knife. You're going to cut one of those religious pictures out of the frame and take it away to hang in the bathroom.'
'No. One more.'
'Your knitting.'
'I don't knit. I don't do anything restful. You ought to know that by now.'
The drinks came. 'Okay,' he said, 'you win. What's in it?'
She lifted the lid of the case. It contained a reporter's notebook, a pencil, and a manual of shorthand.
He stared at these three items. 'Say,' he exclaimed, 'you aren't studying that stuff?'
'What's wrong with that? You said I ought to, once.'
He remembered vaguely what he had once said in an idle moment. 'You taking a course or something?'
'Every morning,' she said. 'I've got to be in Russell Street at half-past nine. Half-past nine-for me. I have to get up before seven!'
He grinned. 'Say, that's bad. What are you doing it for?'
'Something to do. I got fed up with harrowing the dung.'
'How long have you been doing this?'
'Three days. I'm getting awfully good at it. I can make a squiggle now with anyone.'
'Do you know what it means when you've made it?'
'Not yet,' she admitted. She took a drink of brandy. 'That's rather advanced work.'
'Are you taking typing, too?'
She nodded. 'And bookkeeping. All the lot.'
He glanced at her in wonder. 'You'll be quite a secretary by the time you're through.'
'Next year,' she said. 'I'll be able to get a good job next year.'
'Are many other people doing it?' he asked. 'You go to a school, or something?'
She nodded. 'There are more there than I'd thought there'd be. I think it's about half the usual number. There were hardly any pupils just after the war and they sacked most of the teachers. Now the numbers are going up and they've had to take them on again.'
'More people are doing it now?'
'Mostly teen-agers,' she told him. 'I feel like a grandmother amongst them. I think their people got tired of having them at home and made them go to work.' She paused. 'It's the same at the university,' she said. 'There are many more enrollments now than there were a few months ago.'
'I'd never have thought it would work out that way,' he remarked.
'It's dull just living at home,' she said. 'They meet all their friends at the Shop.'
He offered her another drink but she refused it, and they went in to lunch. 'Have you heard about John
