The matting. The pipe.
While they were gone, the candle was burning all the time, the flame gradually descending as the combustion went on, until, about tea-time, it reached the block of wood. It did not set the wood on fire, but the wick fell over, when the flame reached the wood, and communicated the fire to a roll of matting which lay upon the bench behind it. The matting had been used to wrap up plants in, and was damp; so it burned very slowly. About this time, Thomas, the old gardener, came and sat down in the doorway of the tool-house above, smoking his pipe. He did not know, however, what mischief was brewing in the room below; and so, when it began to grow dark, he knocked the ashes out of his pipe upon the ground of the garden, shut the tool-room door, and went home.
Fire! fire!
That night, about midnight, the boys were suddenly awakened and dreadfully terrified by a cry of fire, and, on opening their eyes, they perceived a strong light gleaming into the windows of their bed-room. They sprang up, and saw that the tool-house was all on fire. The people of the house dressed themselves as quick as possible, and hastened to the spot, and some of the neighbors came too. It was, however, too late to extinguish the fire. The building and all the tools which it contained, both in the tool-room and in the shop, and all the seeds that the boys had collected were entirely consumed.
Nobody could imagine how the building took fire. Some said it must have been set on fire by malicious persons. Others thought that old Thomas must have been unconsciously the author of the mischief, with his pipe. Nothing certain, however, could be ascertained at that time, and so the company separated, determining to have the matter more fully investigated the following morning.
William and John, who had dressed themselves when the alarm was first given, and had gone to the fire, now went back to their room, and went to bed again.
What was the origin of the fire? A conversation.
After they had been in bed some time, and each thought that the other must be asleep, William said to John,
“John!”
“What?” said John.
