SINGULAR OBSTACLE TO THE ERECTION OF A BRIDGE AT ROME. —Among the curious facts which have turned up in the course of the Mortmain Committee’s rather discursive investigations, we are told that a ferry across the Tiber, at Ripetta, in Rome, could not be replaced by a suspension bridge as proposed by Pio Nono, because the penny-toll belonged to the souls in purgatory, by legacy of the original proprietor; and the security of a bridge was not held by the trustees to be half so permanent as the natural obstacle of a water privilege; and hence they refused, on behalf of the disembodied spirits, their clients, the chances of increased revenue from the “work pontifical,” which might some day be declared toll free.
