led up some planks leading to one of the floors.

"He is running away!" he heard Jack Sagger cry.

"Come on after him!" said another of the crowd.

"Let's take his new coat and vest away from him!" added a third.

The entire party dropped down into the hole and ran to the rear, in a
hunt after our hero. In the meantime Joe was feeling his way along a
scaffolding where some masons had been at work.

As it happened the entire party under Jack Sagger walked toward the
unfinished building and came to a halt directly under the scaffolding.
Joe saw them and crouched back out of sight.

"Where is de country jay?" he heard one of the crowd ask.

"He's back here somewhere," answered Jack Sagger. "We must find him an'
thump him good."

"You'll not thump me if I can help it," said our hero to himself.

Joe put out his hand and felt a cask near by. It was half filled with
dirty water, being used for the purposes of making mortar. A tub of
water was beside the cask.

"Tit for tat!" he thought, and as quickly as it could be done he
overturned the cask and the tub followed.

Joe's aim was perfect, and down came the shower of dirty water, directly
on the heads of the boys below. Every one was saturated and each set up
a yell of dismay.

"Oh, say, I'm soaked!"

"He trun water all over me!"

"Ugh! but dat's a regular ice bath, dat is!"

"That's what you get for throwing me into the hole!" cried Joe. "After
this you had better leave me alone."

"I've got some mortar in me eye!" screamed Jack Sagger, dancing around
in pain. "Oh, me eye is burned out!"

"I'm wet to de skin!" said Nick Sammel, with a shiver. "Oh, say, but
it's dead cold, ain't it?"

Waiting to hear no more, Joe ran along the scaffolding and then leaped
through a window of the unfinished building. A street light now guided
him and he came out through the back of the structure and into an
alleyway. From this he made his way to the street.

"I'll have to hurry," he reasoned. "If they catch me now they will want
to half kill me!"

"Don't let him git away!" he heard Sagger roar. "Catch him! Catch him!"

"Hold on there, you young rascals!" came a voice out of the darkness.
"What are you doing around these buildings?"

A watchman had come on the scene, with a lantern in one hand and a heavy
club in the other.

"We ain't doin' nuthin," said one of the boys.

"Maybe you're the gang that stole that lumber a couple of nights ago,"
went on the watchman, co
