Second, they dumped ladles of the stuff into clay pots each of which contained a small amount of clove oil. The water fell through the oil and found the bottom of the pot, shedding some of its burden of phosphorus along the way. These pots were then subjected to a similar process of gentle heating, so that the water trapped beneath the oil was driven out as steam. When these pots stopped blurping and steaming, it meant that all the water was gone, and nothing was left but phosphorus suspended in oil. The oil coated the tiny particules of phosphorus and prevented air from touching them, which rendered the stuff safe.
This anyway was the general plan of action. For the most part it actually went this way; but what made it interesting were the mishaps. Every splash and spill remained visible as a pool, burst, or dribbling trail of cold fire. Jack got some splashed on a forearm and did not notice it until he went and stood by the bottle-simmering place for a few minutes; the warmth shining from the bed of coals dried the damp place on his arm, leaving a fine layer of phosphorus that burst into unquenchable flame. Many had similar stories. Presently most of them were naked, having frantically stripped off clothing when it was pointed out to them by excited spectators that they were glowing. Ladles were spilled on the scaffolding by burnt and nervous hands, obliging Monsieur Arlanc to stand his ground with more than human courage as he implored someone to come up and wash away the spill with buckets of fresh water before it dried out. The caulking around the windowpane weeped, then seeped, then began to dribble a steady stream of cold fire. They made shift to catch what they could of this, and confine it to bottles or oil-pots; but matters deteriorated as more and more of the scaffold, the ground beneath it, and the men working on it became tinged with the fire, which could have only one consequence when it dried. Finally Jack ordered Monsieur Arlanc to abandon ship. The Huguenot vaulted down with spryness odd in a man of his age, rending his garments even as he hit the ground; men converged on him with buckets of sea-water and sluiced him off until he was dark. Then all ran away, for the leak around the windowpane had opened wide, and the fire was raining down in a blinding cataract. The water all came out. Air found its way in through the empty bubbler to the chimney, which had become thickly lined with condensed phosphorus. White fire shrieked out of it. The sun rose. What a moment ago had been glowing pools of spilled fire on the black velvet ground, were revealed as damp patches on khaki dirt. The bubbler ripped loose, hurtled away, and impacted on the roof of a monastery half a mile downrange. The chimney and dunce-cap shot into the air, spiraling and pin-wheeling through the night sky as if the Big Dipper had scooped up a load of the sun’s own fire. It landed somewhere out to sea. Left in the vicinity of the scaffold was a metropolis of small sputtering conflagrations that erupted here and there without warning over the next several hours. Fortunately they had had the wisdom to establish the double-boilers for the bottles and the clove-oil pots at a respectful distance. So they abandoned the center and toiled at the periphery until daybreak. This was not without some dangers of its own; sometimes a bottle would crack from the heat, and then some intrepid person would have to pluck it out with tongs and fling it away, lest in burning and exploding it would detonate the others. This led to the burning-down of the house where they had all been dwelling. In other circumstances, the loss of their domicile would have been rated a grave setback; as it was, they knew they were going to be kicked out of town anyway. A formation of Portuguese pikemen came for them at daybreak. Working amid the smoldering ruins of what had, a month earlier, been a perfectly respectable brewery, Jack and the others had already loaded the bottles (packed very carefully in straw) and the pots of oil into crates, and the crates onto those wagons that remained unburnt, and harnessed these to the few domesticated beasts that had not run away or simply dropped dead of terror during the night-time. They were escorted, not to say pursued, by the pikemen down to the quay where they boarded their hired boat with the phosphorus and what few possessions they still had. Winds favored them; pirates, who had witnessed strange apparitions in the night sky above Diu, avoided them; and a day and half a later they were in Surat, taking up their position near the head of a great armed trade-caravan, and beginning the long march north and east to Shahjahanabad.
