“Populace has been warned out of the city. All roads are packed with refugees. The Berkeley Hills are covered as with flies—north, east, and south and on the boats to Frisco. The poison, whatever it is, is advancing in a ring from Fourteenth and Broadway. You have got to pass it to these old boys of science. They are staying with that ring. Already they have calculated the rate of its advance and have given warning. They don’t know what it is, but they have figured just how fast it is moving. They have saved the city. “I am one of the few men now inside the wave. Out of curiosity I have stuck. I have a jug and as long as it lasts I shall stay. Strange feeling. Dry, dry, dry, as if the juice of one’s life cells was turning into dust. Water evaporating almost instantly. It cannot pass through glass. Whatever the poison it has an affinity for moisture. Do not understand it. I have had enough—” That was all. After that there was no more news out of Oakland. It is the only word that we have out of the pall itself. It was short and disconnected and a bit slangy; but for all that a basis from which to conjecture. It is a strange and glorious thing how some men will stick to the post of danger. This operator knew that it meant death; but he held with duty. Had he been a man of scientific training his information might have been of incalculable value. However, may God bless his heroic soul! What we know is thirst! The word that came from the experts confirmed it. Some new element of force was stealing or sapping the humidity out of the atmosphere. Whether this was combining and entering into a poison could not be determined. Chemists worked frantically at the outposts of the advancing ring. In four hours it had covered the city; in six it had reached San Leandro, and was advancing on toward Haywards. It was a strange story and incredible from the beginning. No wonder the world doubted. Such a thing had never happened. We had accepted the law of judging the future by the past; by deduction; we were used to sequence and to law; to the laws of Nature. This thing did look like a miracle; which was merely because—as usually it is with “miracles”—we could not understand it. Happily, we can look back now and still place our faith in Nature. The world doubted and was afraid. Was this peril to spread slowly over the whole state of California and then on to the—world. Doubt always precedes terror. A tense world waited. Then came the word of reassurance—from the scientists: “Danger past; vigor of the ring is abating. Calculation has deduced that the wave is slowly decreasing in potentiality. It is too early yet to say that there will be recessions, as the wave is just reaching its zenith. What it is we cannot say; but it cannot be inexplicable. After a little time it will all be explained. Say to the world there is no cause for alarm.”
