"I believe it is," he asserted. "I thought I could make out arms and legs but I wasn't sure. If it is a man, he must be in a mighty bad fix."

A sudden idea occurred to Burt and he glanced at his chum. Critch met his eye and read the unspoken thought. When Burt raised his glasses again his face was white.

Now the natives were surrounding the strange figure, and a moment later one of them waved his spear. The others could be seen lifting the creature, whatever it was, and speedily carried him to the river.

"Come along," and Mr. Wallace rose hastily. "We'll go down and meet them. If it's a man he'll need help. John, did you bring the small medicine case?"

"Here, sar," and as if by magic the grinning black produced the required object. They all hurried down to the river, where the villagers were already crowding around in great curiosity. The little band of natives splashed across the stream, and suddenly Burt felt his uncle grip his arm.

"Burt!" and he had never before heard such tense horror in a man's voice. "Go up and get some water boiling right away! Hurry, lad, hurry!" Without pausing to ask questions Burt dashed off. As he went he could hear his uncle continuing. "John, make for the camp right away. Get out bandages, have hot water, make the hypodermics ready and mix some strong morphia and anti-toxin solution. That is Captain Montenay." John was off at a run instantly.

The last words struck Burt like a blow. With pale face he got the water heating, and met his uncle as the latter ordered the senseless form of Captain Mac set down. The explorer was unrecognizable. He was plastered with mud from head to foot and his whole body was swelled and poisoned until he bore small resemblance to a man. Mr. Wallace gave a glance around, then shook his head.

"We can do nothing here. Boys, we'll have to work to save him. Looks to me like black wasp stings." Turning to Mvita, he ordered Montenay's body carried to the village at top speed. Instantly four natives caught up the senseless figure and made off at a lope.

Mr. Wallace and the boys dropped everything and followed. When they reached the camp after a hard march they found John bathing the swollen body of Captain Mac, and Mr. Wallace went to work at once with the medicines that lay ready. With the mud and dirt removed, Montenay's horrible condition only became more evident. Mr. Wallace went to work with the hypodermic while the boys aided John to cleanse the explorer's body, then handed the syringe to John to clean and turned to the bandages and lint.

The countless stings were washed with a weak solution of ammonia to take out the poison, and an hour later they left the Scotchman a mass of bandages but sleeping soundly.
