"Scurvy is a sore mouth, isn't it?" asked Tom.
"Not by any means," answered the Doctor. "Sore mouth is one of the earliest and mildest symptoms of the disease, and nobody knows what sore mouth means till he has had a touch of scurvy. It means that the mouth in all its membranes is afire, and that everything put into the mouth,—even though it be a piece of ice—burns like so much molten iron. But the mouth symptoms are only a beginning. Presently the knees and other joints turn purple and become excruciatingly painful. Then they suppurate, and in the end amputation becomes necessary. There are few worse diseases than scurvy, and we boys must protect ourselves against it by every means in our power. It threatens us with a much more serious danger than any that the moonshiners can bring upon us."
"By the way," said Jack, "the moonshiners seem to be letting us alone now. Perhaps they have given us up as a bad job."
"That's just what they want us to think," responded Tom. "They are lying low, in the hope that we'll accept precisely that idea and relax our vigilance. That is the one thing that we mustn't do on any account. That reminds me that it's time for me to go and relieve Jim Chenowith on guard duty."
"Well, before you go, Tom," said the Doctor, "I want to suggest that you take a day off to-morrow and get some fresh meat for us. We have lived on salt meat for five or six days now, and a big snow may come at any time to cut us off from fresh meat supplies. Besides our provisions are very sharply limited in quantity and we mustn't use them up too rapidly. We don't want scurvy in the camp and we don't want a starving time. So boys I propose that Tom, as the best huntsman in the party, be detailed and ordered to devote to-morrow to the duty of getting some game for our larder."
The suggestion was instantly and unanimously accepted. Then spoke up Harry Ridsdale:
"It'll be a hard day's work for Tom, as there's a slippery, soaplike snow on the ground, and he needs to be fresh for it. So I volunteer to take his turn on guard to-night and let him get in a good, straightaway sleep."
"Good for you, Harry," said Jack. But Tom protested that he was perfectly ready to stand his turn of guard duty and insisted upon doing so. The others unanimously overruled him, however, and so Harry shouldered his gun and went to relieve Jim Chenowith as picket. Before going he said:
"Now, fellows, there is to be no more talking to-night, for when the Doctor talks I want to listen. I've a whole catechism of questions to bother him with, but it's bed time now and you fellows must crawl into your bunks at once, without any further chatter. To bed, every one of you!"
As it was full ten o'clock the boys accepted the suggestion, and in a few minutes afterward, Camp Venture sank into silence, while Harry stood guard out there under the cliff, and the stars glittered above him in a wintry sky. Meantime the logs blazed and sputtered lazily in the great fireplace, and the night wore on, with no disturbance in the hut except when a sentinel came in, woke up his successor, replenished the fire and crept into his broomstraw bed.
