CLIFFSIDE SANITARIUM. PRIVATE GROUNDS.
"Sanitarium!" exclaimed Frank, as the memory of the conversation of the two men, of which Ned had told him, came to his mind. "I wonder if this can be the place. Sanitarium! Probably a place for mildly insane persons. That would be it. It says 'private grounds' and that likely means no trespassing; but what am I to do? I've got to stay somewhere to-night, and I can't possibly get back to camp. I'll make a circuit around the place and see how it looks."
Keeping in the shadow of the woods, Frank made a wide circle around the sanitarium. Then he came to a stop, when he was near the front, for he had come to the edge of a high cliff, on which the building stood.
"That's where the name comes in," thought the boy. "It's on the cliff. Well, I think I'll ask if I can stay all night. I hope they don't take me for a lunatic, and perhaps some of the doctors or nurses can tell me what I want to know."
Frank was about to advance toward the front of the institution, up a path that led from the edge of the woods where he stood, when he saw a line of men leave the sanitarium, and start to walk around the paths about the building. At the first glance Frank knew what they were.
"They are the patients out for exercise," he decided. "I must get closer. They're coming this way. I'll hide in the woods," and, getting behind a big oak, the boy awaited the oncoming of the line of sad-faced men.
Slowly the patients filed past. They all seemed to be suffering from some ailment, mental or physical, and all had an unhealthful pallor. Walking ahead, in the rear, and on both sides, were men dressed in dark blue uniforms.
"Attendants," mused Frank, "though none of the patients look as though they were violent."
By this time the head of the line had turned and the sad little procession was moving away from Frank, as he stood behind the tree. The men in the rear were now passing close to him, and the boy, seeing that the end of the line was near, prepared to go forward when they all should have passed. As he was about to step from his place he caught sight of the face of one of the patients, and, as he did so, he uttered an involuntary cry. Before he was aware what he was doing, Frank had stepped from behind the tree.
Several of the patients saw him, and gazed curiously at the boy. One—the one at the sight of whom Frank had uttered the exclamation—did not look up. With his eyes bent on the ground he hurried on, following the man ahead of him. There was a little confusion, caused by some of the patients stopping to stare at Frank, and two attendants came up on the run. One of them saw the boy standing beside the big tree.
