efore their hammering on the gate aroused the attention
of the night-watchman--who was also the day-watchman--who occupied what
had been in former days the weigh-house, which he had converted into a
weatherproof lodging.

"Hullo!" he said huskily. "I was asleep."

He recognized Mr. Sole, and led the way to his little bunk-house.

"Look here, Tester," said Sole, who had appointed the man, "did a young
swell come down here to-day?"

"He did," said Mr. Tester, "and a young lady. They gave Mr. Staines's
name, and asked to be showed round, and," he added, "I showed 'em
round."

"Well, what happened?" asked Staines.

"Well," said the man, "I took 'em in the factory, in the big building,
and then this young fellow asked to see the place where the metal was

"What metal?" asked three voices at one and the same time.

Staines gripped his nearest companion in sin, and demanded huskily:

"Did they find anything in--in the vault?"

"Blessed if I know!" said the cheerful Tester, never dreaming that he
was falling very short of the faith which at that moment, and only at
that moment, had been reposed in him. "They just went in. I've never
been inside the place myself."

"And you stood outside, like a--a----"

"Blinking image!" said the explosive companion.

"You stood outside like a blinking image, and didn't attempt to go in,
and see what they were looking at?" said Mr. Staines heatedly. "How
long were they there?"

"About ten minutes."

"And then they came out?"

Tester nodded.

"Did they bring anything out with them?"

"Nothing," said Mr. Tester emphatically.

"Did this fellow--what's his name?--look surprised or upset?" persisted
the cross-examining Honest John.

"He was a bit upset, now you come to mention i
