As the dog reached Amsterdam Avenue a high little voice squealed delightedly at him. A three-year-old baby—a mere fluff of gold and white and pink—was crossing the avenue convoyed by a fat woman in black. Lad was jogging by the mother and child when the latter discovered the passing dog.

With a shriek of joyous friendliness the baby flung herself upon Lad and wrapped both arms about his shaggy neck.

"Why doggie!" she shrilled, ecstatically. "Why, dear, dear doggie!"

Now Lad was in dire haste to get home, and Lad was in dire misery of mind and body, but his big heart went out in eagerly loving answer to the impulsive caress. He worshipped children, and would cheerfully endure from them any amount of mauling.

At the baby embrace and the baby voice, he stopped short in his progress. His plumy tail wagged in glad friendliness; his muzzled nose sought wistfully to kiss the pink little face on a level with his own. The baby tightened her hug, and laid her rose leaf cheek close to his own.

"I love you, Miss Doggie!" she whispered in Lad's ear.

Then the fat woman in black bore down upon them. Fiercely, she yanked the baby away from the dog. Then, seeing that the mud on Lad's shoulder had soiled the child's white coat, she whirled a string-fastened bundle aloft and brought it down with a resounding thwack over the dog's head.

Lad winched under the heavy blow, then hot resentment blazed through his first instant of grieved astonishment. This unpleasant fat creature in black was not a man, wherefore Lad contented himself by baring his white teeth, and with growling deep menace far down in his throat.

The woman shrank back scared, and she screamed loudly. On the instant the station-bound patrolman was beside her.
