As Ben sent the canoe shooting past that point it came near colliding with another canoe that contained a single occupant, who was smoking a pipe and paddling along leisurely.

"Look out, you lubbers!" grunted the man with the pipe. "What are you trying to do?"

It was Bruce Browning, who, after all, had found it impossible to remain at the cottage. In Joe's canoe Bruce was leisurely paddling over to the south shore, thinking he would look in on the dancers. He had not heard the approach of the other canoe and knew nothing of its presence until it shot past the point and nearly struck him.

Neither Red Ben nor his companion made any retort. The Indian swerved the canoe aside and continued to ply the paddle, flashing past Bruce.

Browning stared in surprise, for the moonlight fell full and fair on the redskin's companion, showing the wolf mask.

"One of the dancers, I judge," he mumbled. "Nice, sociable fellow! Never said a word when they came so near cutting me in two. What's he doing now?"

Bruce swung his canoe so he could watch the other without cramping his neck, for he saw that something like a struggle was taking place, the masked man seemingly holding some object helpless in the bottom of the frail craft.

"Queer doings," growled the big fellow. "I'd like to know what it means. There seems to be some sort of excitement going on yonder."

He turned from the canoe to listen to the sounds on shore.

"Guess I'll poke along and find out what all the racket is," he decided, as he resumed his lazy paddling, giving no further attention to the other canoe.

Arriving at the landing, Bruce made his way to the pavilion. Ere he reached it he was certain something of an unusual nature had taken place. Persons were searching with lights in the grove, and he encountered a party of four, who surveyed him searchingly and passed on.

He had reached the pavilion when he encountered Hodge, who was doing his best to quiet Elsie, the latter apparently being on the verge of hysterics.

"What's the matter, Bart?" asked Bruce, wonderingly. "What's happened here, anyhow?"

Hodge clutched him by the shoulder.

"Inza!" he exclaimed. "She has disappeared mysteriously."

The big fellow immediately threw off his apathy. His careless, lazy air vanished in a twinkling and he asked some questions that brought a brief but complete explanation from Bart.

"Where is Frank?" demanded Browning.

"He is with the searchers."

Bruce lost no time in looking for Merriwell, soon coming face to face with him in the grove. Frank's face was pale and stern, and there was a dangerous, desperate gleam in his eyes.

"You're wasting your time here, Merry," declared Bruce. "Hodge has just told me of the men who wore the wolf masks. There must have been three of them. While you were having that set-to with two of them the third carried Inza off."

"But where is she?" asked Frank hoarsely. "Where did he take her?"

"You won't find her on shore. Look on the lake."

"The lake?"

"Yes."

"Why——"

Immediately Browning told how he had seen one of the men wearing a wolf mask in the canoe which so nearly collided with the one he occupied.

"There was something in the bottom of that canoe. I fancied a struggle was taking place. I thought it mighty singular."

"By Heaven!" cried Frank, "if a hair of Inza's head is harmed the guilty wretch shall pay the penalty with his life!"
