"Now—" said the scared youth, glibly, avoiding his father's unsuspecting eye. "Now—now, Lad he was settin' 'twixt Simmons and me. And he hops down and runs off around the house, towards—towards the lake—soon as we stopped here. Most likely he was thirsty-like, or something."

The Mistress was busy with details of the car's unpacking. So she accepted the explanation. It seemed probable that the long and dusty ride should have made Lad thirsty; and that after his drink at the lake, he had made the rounds of the Place; as ever was his wont after his few brief absences from home.

Not until dinnertime did she give another thought to her loved pet's absence. The guide and his boy had long since departed, on the truck, for their ten-mile distant home. Nor, even yet, did it occur to the Mistress to question the truth of the youngster's story. She merely wondered why, for the first time in his life, Lad should absent himself at dinnertime from his time-honored place on the dining-room floor, at the Master's left. And, amusedly, she recalled what her husband had said of the stately dog's new propensity for mischief. Perhaps Lad was exploring the friendly home-woods in search of a bear!

But when ten o'clock came and Lad did not seek the shelter of his "cave" under the music-room piano, for the night, there was real worry. The Mistress went out on the veranda and sounded long and shrilly upon the silver whistle which hung from her belt.

From puppyhood, Laddie had always come, at a sweeping gallop, on sound of this whistle. Its notes could travel, through still air, for a half mile or more. Their faintest echoes always brought the dog in eager response. But tonight, a dozen wait-punctuated blasts brought no other response than to set the distant village dogs to barking.

The Mistress went back into the house, genuinely worried. Acting on a sudden idea, she called up the Place's superintendent, at the gatelodge.

"You were down here when the truck came to the house this afternoon, weren't you?" she asked.

"Yes, ma'am," said the man. "I was waiting for it. Mike and I helped Simmons to unload."

"Did you see which way Lad went, when he jumped out of the truck?" pursued the Mistress. "Or have any of you seen him since then?"

"Why, no, ma'am," came the puzzled answer. "I haven't seen him at all. I supposed he was in the car with you, and that maybe he'd been in the house ever since. He wasn't on the truck: That's one sure thing. I saw it stop; and I stayed till they finished emptying it. Lad wasn't there."
