Then came the Lieutenant with a squad of soldiers to remove the wounded men from the hut. This was a work of some difficulty although all the men were now "making satisfactory recovery" as the Doctor phrased it. The Doctor took charge at this point because he knew as no one else did the exact nature and condition of each man's wound, and it was his care to see that none should be improperly handled or in any way injured in the removal. Yet the house burned so rapidly that there was very little time for care and the excited soldiers had to be sharply restrained by the Lieutenant to make them comply with every direction of the Doctor in their handling of the wounded men.
Meantime the boys removed from the house everything of value, including even the "piano," which they would need every day for the sharpening of their axes.
What had happened was this: the upper part of the chimney, as the reader will remember, had been built of sticks, laid in a crib, and daubed all over with mud. The sticks were green, full of sap and almost incombustible when placed in position, and besides that the mud daubing protected them. But little by little the mud had dried and fallen away. While the heat of a fire that was maintained night and day for many months had seasoned the sticks first and then dried and parched them to the condition of tinder, capable of being ignited by the merest spark.
That night the spark did its work. The chimney sticks caught fire and burned with fierce violence. The clapboards forming the roof and the resinous pine timbers that held them in place, had also been roasted into an exceedingly combustible condition, and by the time that the fire was discovered the house was obviously doomed. That was the origin of the light that Tom had seen in the direction of Camp Venture while waiting for his bear.
When he now entered the camp he found the boys getting breakfast by an out door fire, built near the mouth of the chute.
"Poor old Camp Venture!" he exclaimed. "How did it happen boys?"
They hastily explained especially answering Tom's eager questions as to the condition of the wounded men.
"They are quite comfortable," said the Doctor. "All possible care was taken in removing them from the burning house, and my examination discovers no trace of damage done to any of them. But where have you been and what have you brought back with you?" for Tom had no game in possession.
"I've been to the home and headquarters of Ursa Major, and I've killed him," answered Tom. "I want to borrow the Lieutenant's glass to-night to see how the heavens look without the constellation of the Great Bear."
"What do you mean, Tom?" asked the boys eagerly.
