Who forgets the relief expeditions started in wagons and on foot from every point of the compass? These were invariably repelled on reaching the dead line. We could understand the fetid miasma that made the Great Dismal Swamp an unknowable country. We could comprehend the encroaching dead line of the spreading yellow fever bacillus. But this fearful death, that brooded silently, impenetrably, mysteriously and occultly over a vast area once the garden of civilization, baffled all attempts at explanation. Even birds were observed to vacate this tract. Only a few sinister buzzards wheeled their flight, with straight, unflapping wings, high above Russell, almost out of sight, as if they were the embodied ghosts of Russell's unbaptized inhabitants. What was that implacable power? Reporters and trackmen who steadily scoffed at it were themselves attacked with violent heart-beats when they crossed the invisible and fatal line. A convulsion of all the members followed, as if in an epileptic fit,--insensibility and, generally, death ensued. Many who were with difficulty rescued, and who finally recovered, averred that they experienced an overcoming odor, acid and penetrating, such as is peculiar to ozone when manufactured in a chemical laboratory. At the end of the fourth day of Russell's complete isolation a despair settled upon the country. England was staggered by the uniqueness of these phenomena. The French Academy of Sciences, after a prolonged sitting, announced that they could suggest no solution. It is only too well remembered that the newspaper bulletins were besieged in our own cities, but these offered no further information or encouragement. Was advanced civilization responsible for this disaster or not? That was the burning question. Or was this a special visitation of God, a plague new to the medical world, spontaneously generated, sporadic in its appearance, and destined forever to be an _obscurum per obscurius_ or perhaps to spread with further undetermined horrors? Thousands were now on the ground. They encompassed that section about as Joshua did the city of Jericho, as the settlers did the Territory of Oklahoma on the day of its opening, as the rabble do a house when a murder has been committed. On the evening of the fourth day from the time when the messenger boy brought the first despatch to the office of the _Daily Planet_, its chief, obviously nervous for the first time in his public life, received the following cipher telegram, which cheered him wonderfully: "_On the spot. Situation desperate. Worse than described. Will penetrate to Russell or die. Dead line still impassable. Trust me._ "SWIFT" III.
