But the animal crouching at the Wall Street Farmer's feet was quite a different form of guest. Lad recognized the thing as a dog--yet no such dog as ever he had seen. An unwholesome-looking dog. Even as the little boy was an unwholesome-looking child. "Well!" sonorously proclaimed the Wall Street Farmer as he scrambled out of the runabout and bore down upon his hosts, "here I am! The sheep got here all safe? Good! I knew they would. McGillicuddy's a genius; nothing he can't do with sheep. You remember Mortimer?" lifting the lanky youngster from the seat. "He teased so to come along, his mother said I'd better bring him. I knew you'd be glad. Shake hands with them, Morty, darling." "I wun't!" snarled Morty darling, hanging back. Then he caught sight of Lad. The collie came straight up to the child, grinning from ear to ear, and wrinkling his nose so delightedly that every white front tooth showed. Morty flung himself forward to greet the huge dog, but the Wall Street Farmer, with a shout of warning, caught the boy in his arms and bravely interposed his own fat body between Mortimer and Lad. "What does the beast mean by snarling at my son?" fiercely demanded the Wall Street Farmer. "You people have no right to leave such a savage dog at large." "He's not snarling," the Mistress indignantly declared, "he's smiling. That's Lad's way. Why, he'd let himself be cut up into squares sooner than hurt a child." Still doubtful, the Wall Street Farmer cautiously set down his son on the veranda. Morty flung himself bodily upon Lad; hauling and mauling the stately collie this way and that. Had any grown person, save only the Mistress or the Master, attempted such treatment, the curving white eyeteeth would have buried themselves very promptly in the offender. Indeed, the Master now gazed, with some nervousness, at the performance; but the Mistress was not worried as to her adored pet's behavior; and the Mistress, as ever, was right. For Lad endured the mauling--not patiently, but blissfully. He fairly writhed with delight at the painful tugging of hair and ears; and moistly he strove to kiss the wizened little face that was on a level with his own. Morty repaid this attention by slapping Lad across the mouth. Lad only wagged his plumy tail the more ecstatically and snuggled closer to the preposterous baby. Meantime, the Wall Street Farmer, in clarion tones, was calling attention to the second of the two treasures he had brought along. "Melisande!" he cried.
