e police began pounding on the front doors just as the Bradys rushed out
into the rear yard.

Just as they emerged. Harry saw the figure of Jean disappearing over the
back fence and pointing at it, he cried excitedly:

"There they go!"

"After them!" roared Old King Brady.

They rushed across the yard.

Over the fence they climbed like a couple of cats, and leaping into the
yard of an adjoining tenement, they ran for the hall.

Blood spots on the flags left a plain trail.

The wounded men had dropped it in their flight, and the detectives easily
traced the stains through the hall into the street.

Hearing wild yells, they saw a baker's wagon dashing along at a furious
gallop, and saw Clara and her friends in it.

The owner of the wagon was racing out of his store.

A small boy had told him that a gang had stolen his horse and wagon and it
was his yells the detectives heard.

He was a fat German and he paused in the middle of the street, wildly
waving his arms and crying in despairing tones:

"_Ach Gott!_ I vos robbed! Dey shtole mein horse und vagon!"

The Bradys started off on a run after the vehicle.

Block after block was covered until the wagon, far in advance of the
detectives, swung around the corner into West Broadway.

Here, panting and foam-covered, the horse was reined in.

The fugitives alighted.

"We are going to lose them now," groaned Old King Brady.

"I don't see why," returned Harry, breathlessly.

"Don't you see they're going for the elevated?"

"Oh, gee, so they are!"

The five rushed up the stairs on the downtown side, just as a train pulled
into the station.

After them ran the Bradys, hoping fervently that they would miss the train.
But they were doomed to disappointment.

When the detectives reached the platform, the train was steaming away and
they saw their enemies in the last car.

"That's the end of them!" said Old King Brady.

"Can't we have them headed off by telephoning down to the Battery station?"
eagerly asked the boy.

"Might try."

Down the street they went and as there was a public telephone near by, they
sent the message down.

Then they took the next train down.

The train on which the fugitives stopped was yet at the Battery station and
they found the gateman of the last car and Harry asked him:

"Did you notice where the four men in black, and a hatless girl of sixteen
who got on at the Bleecker street station alighted?"

"Oh, yes. I remember
