The track has a total length of about sixty-five yards, inclusive of loop and exit. The loop is about twenty-four feet high. The wheel rolls in a mould-shaped groove. The slightest mistake in the construction of the track, which is an extremely ingenious one, would result in an unsuccessful performance and a dangerous, if not deadly, fall. Especially ingenious is the mechanism of the trap-doors at the entrance and exit. These are in charge of the artist's colleague, and form the most important part of the track, as any failure in this part would end in dire catastrophe. LXX.--A BONFIRE OF GAMBLING APPARATUS. The Anti-Gambling Leagues of British cities have their counterpart in the various Law and Order Societies of American municipalities, and their labours are much the same. Just as the societies in England attempt to protect the poor and middle-class people from the encroachments of vice by initiating prosecutions against wrong-doers, so do these Law and Order Societies fight in the interests of the American public. They go to excesses sometimes, it is true, but their labours have a positive value for good. In England they keep an eye upon the book-maker in the street, upon the sporting tipster with his betting circulars and notices, and upon gambling in general. They prosecute where prosecution is needed, and carry on in Parliament a fight for virtue. Never, however, have they prepared a fire for the benefit of their supporters such as the Law and Order Society of Philadelphia got up last May. It is, perhaps, not wholly correct to say that when the Philadelphia Society seized and burned over thirteen hundred gambling machines in a public place it did so merely for the benefit of its followers, but that was practically the case, and among those who saw this unique conflagration there were none more interested than the crusaders against vice. It was an actual destruction of valuable property, but not a wanton one, and when the fire was over the charred metal and molten tin represented a sum of not less than one hundred and thirty thousand dollars. We doubt if England has ever had the privilege of witnessing such a sight, for the vested right of the Briton is too sacred to permit of his property being done away with in such brilliant manner.
