that's the Fire Department," grunted Fay. "About time they
turned up!"

"There's oil in that fire!" snapped the tanner, gazing at the black
smoke. "Where'd it come from?"

"Two five-gallon tins of it, brought from D building, spilled on the
floor and a match chucked into it. I seen them lying on their side in
there at the start of it."

"Humph. Brought from D building, eh? Then there's no doubt of _this_
being the work of an incendiary!"

"Doubt? Huh! I'll tell the world there ain't no doubt! I seen the
feller that did it!"

"Ah! Could you recognize him? Who was it? Why in thunder didn't you
grab him? Where'd he get to?"

Before Fay could even begin to sort out these questions and try to
answer the easier ones, their quick conversation was interrupted by the
appearance of a resplendent figure at their elbows. A short, stout man
was Gus Wimpelheimer, grocer and butcher by profession and in his
lighter moments Chief of the Hambleton Fire Department. His round
little body was now quivering with pleased excitement.

"Evening, gentlemen!" he greeted them politely. He glanced at the fire
and wrinkled an expert nose. "Kerosene!" he pronounced.

"The thought had occurred to us," retorted Simon. Marshal Wimpelheimer
trotted briskly toward the fire for a better view, and trotted briskly

a little whistle to his lips and its squeaky notes brought two
satellites of the main luminary. "Hustle out those chemicals and get
'em to work on the blaze. Rout out all the buckets you can find, and
send for more. Call on that crowd out there for volunteers and get a
chain started from the stream to these other buildings. Douse
'em--douse 'em _good_! Don't stop till I tell you to. Fay! You'll
know where there are any ladders; fetch them out!"

"Yes, Chief!" came the admiring chorus, and the men sprang off to
execute his orders. He rubbed his hands together with satisfaction and
turned brightly to the tanner.

"Don't you worry, Mr. Varr," he said indulgently. "We'll handle this
little affair for you!"

Worry was not exactly Varr's predominant emotion. There was small
reason to fear that the remainder of the buildings would not be kept
intact, and there was ample insurance on the property, including
contents. The blaze could c
