341 ODD AUTO SCORE

BOARD AT recent California auto road races, a specially designed

score board was erected, facing the grand stand, which enabled the spectators to follow the movements of each racing car about the eight mile course. Telephone stations had been set up at half mile intervals around the course where an operator reported as each car passed. These telephones were connected with the judge's stand, where a man was stationed behind the board to receive the reports and to move the numbers representing the

cars move ing to the black and wh i te spaces that were marked for

FELLING A CHIMNEY

LIKE A TREE THIS stack, which was 1 thrown, stood ten feet square at the base, and one hundred feet high, was built of common brick, lined with fire brick and was topped out with a cast iron cap.

It will be seen that the method of throwing this stack was quite similar to that of cutting down a large tree. Brick work on one side was cut out, extreme care being taken to make the cutting symmetrical on each side of the center line of the stack. This method of cutting was continued until the weight of the stack began to crush the brickwork at the edge of the cutting, and as soon as this occurred the great hill of bricks of course fell to that side.

So accurately was the work done that the fallen stack lay exactly parallel with the sidewalk, as was intended. The outer shell crushed downward, while the inner lining maintained its original shape until the

falling stack struck the ground when it, in its turn, also collapsed.

This stack stood at Cleveland, Ohio. It was removed in order to make room for a large new incandescent lamp factory.

This method of felling a brick stack, of course, has to be very carefully understood and thought out by the man in charge. If this be not the case a serious disaster may be the result, as a falling stack surrounded by houses is very different from a falling tree in a forest, many miles away from a habitation.
