My hesitation was but momentary. I flung open the window, leaped out and commenced running along the trail of the daring, unknown visitor. The visit had been so recent that I was spurred by a faint hope of overtaking the fellow.

I had not proceeded far before I heard a shout from the house. I glanced back without slacking, and saw Stodger staring at me in amazement from an up-stairs window. Motioning to him to remain where he was, I continued to follow the footprints.

As soon as the bushes screened me from the house, I arrived at a point where the trail presented a new aspect: the distance between the impresses measurably widened, signifying that my unknown caller had broken into a run the instant the shrubbery concealed him from the house. I quickened my pace.

The chase led me to a low stone wall marking the boundary of the premises, across some vacant lots, to the intersection of two streets, where the presence of a trolley line discouraged further pursuit.

On one of the corners, however, stood a grocery of the suburban variety; and when I arrived hatless and without an overcoat, the grocer came out, and eyed me curiously.

"Did you see anybody just ahead of me come this way?" I panted.

"Yep," returned the grocer. "Fellow came running across those lots not five minutes ago. Three other fellows waiting for him on the corner here."

"Three others!" I exclaimed. I had n't the least idea what it all meant.

"Yep," said the grocer. "When he came there were four. The whole bunch caught a down car. They was Chinymen."

I could do no more than vent my bewilderment in ejaculations.
