For, idle as that figure seemed, the brain behind it was forever active, forever vigilant and alert. The deep-set eyes under their lids that hung as loose as old parchment were always fixed on the life that flowed past them. No face, as those eyes opened and closed like the gills of a dying fish, escaped their inspection. Every man who came within their range of vision was duly examined and adjudicated. Every human atom of that forever ebbing and flowing tide of life had to pass through an invisible screen of inspection, had in some intangible way to justify itself as it proceeded on its unknown movement towards an unknown end. And on the loose-skinned and haggard face, had it been studied closely enough, could have been seen a vague and wistful note of expectancy, a guarded and muffled sense of anticipation.

Yet to-day, as on all other days, nobody stopped to study the old cement-seller’s face. The pink-cheeked young patrolman, swinging back on his beat, tattooed with his ash night-stick on the gas-pipe frame and peered indifferently down at the battered and gibbeted crockery.

“Hello, Batty,” he said as he set the exhibit oscillating with a push of the knee. “How’s business?”

“Pretty good,” answered the patient and guttural voice. But the eyes that seemed as calm as a cow’s eyes did not look at the patrolman as he spoke.

He had nothing to fear. He knew that he had his license. He knew that under the faded green of his overcoat was an oval-shaped street-peddler’s badge. He also knew, which the patrolman did not, that under the lapel of his inner coat was a badge of another shape and design, the badge which season by season the indulgent new head of the Detective Bureau extended to him with his further privilege of a special officer’s license. For this empty honor “Batty” Blake—for as “Batty” he was known to nearly all the cities of America—did an occasional bit of “stooling” for the Central Office, a tip as to a stray yeggman’s return, a hint as to a “peterman’s” activities in the shopping crowds, a whisper that a till tapper had failed to respect the Department’s dead-lines.

Yet nobody took Batty Blake seriously. It was said, indeed, that once, in the old régime, he had been a big man in the Department. But that Department had known many changes, and where life is unduly active, memory is apt to be unduly short.

The patrolman tapping on the gas-pipe arch with his idle night-stick merely knew that Batty was placid and inoffensive, that he never obstructed traffic and always carried a license-badge. He knew that in damp weather Batty limped and confessed that his leg pained him a bit, from an old hurt he’d had in the East. And he had heard somewhere that Batty was a sort of Wandering Jew, patroling the whole length of the continent with his broken plates and his gas-pipe frame and his glue-bottles, migrating restlessly from city to city, striking out as far west as San Francisco, swinging round by Denver and New Orleans and then working his way northward again up to St. Louis and Chicago and Pittsburgh.

Remembering these things the idle young “flatty” turned and looked at the green-coated and sunken-shouldered figure, touched into some rough pity by the wordless pathos of an existence which seemed without aim or reason.

“Batty, how long’re yuh going to peddle glue, anyway?” he suddenly asked.

The glue-peddler, watching the crowds that drifted by him, did not answer. He did not even look about at his interrogator.
