When you see a bright light reflected on the crowd below, throw open the shutters, and hurl down stones as long as the light is shining.

Now, take your places, and as soon as you are prepared stamp upon the floor." Each of the men now armed themselves with two or more of the largest stones they could find, from the heap that had been provided for the occasion; and in a few seconds a loud stamping upon the floor informed Mr.Walters that all was ready.

He now opened the aperture in the shutter, and placed therein a powerful reflecting light which brought the shouting crowd below clearly into view, and in an instant a shower of heavy stones came crashing down upon their upturned faces.
Yells of rage and agony ascended from the throng, who, not seeing any previous signs of life in the house, had no anticipation of so prompt and severe a response to their attack.

For a time they swayed to and fro, bewildered by the intense light and crushing shower of stones that had so suddenly fallen upon them.

Those in the rear, however, pressing forward, did not permit the most exposed to retire out of reach of missiles from the house; on perceiving which, Mr.Walters again turned the light upon them, and immediately another stony shower came rattling down, which caused a precipitate retreat.
"The house is full of niggers!--the house is full of niggers!" cried several voices--"Shoot them! kill them!" and immediately several shots were fired at the window by the mob below.
"Don't fire yet," said Mr.Walters to one of the young men who had his hand upon a gun.
