Some skippers prefer to have their vessels towed by one powerful tug, while others prefer several smaller ones. Several tugs are now building for towing purposes, and they will also be used to tow vessels through the locks in the early days of operation, pending the completion of all of the electric towing locomotives. Two floating cranes will be provided in the permanent equipment at a cost of a quarter of a million dollars each. These cranes, with a lifting power of 250 tons, will be suitable for any wrecking operations in the canal and, also, for lifting the gates in case of repairs being required. The canal will probably be the death blow to the sailing ship of international commerce. Not being able to negotiate the canal under their own power, and because of the dead calms which prevail in the Gulf of Panama, sailing ships will be stopped from using the Isthmian waterway. When they attempt to journey around Cape Horn and the Cape of Good Hope in competition with steam vessels which pass through the Panama Canal, the operation will afford such little profit that in the course of a few years they will have to surrender what little share of international commerce they have succeeded in keeping. The Panamans are inclined to think the United States drove a hard bargain when the provision was inserted in the treaty that all supplies for the building and operation of the canal, and for the demands of shipping using it, when imported by the United States, should be free of duty. This practically gives the United States a monopoly of the business of catering to the needs of ships passing Panama. The present duty on imports is 15 per cent, and the local merchant who would sell supplies to the passing ships would be under the necessity of adding 15 per cent to his buying price before he could compete with the United States Government on equal terms. This advantage is made all the more marked by the reasons of the fact that the United States often can make much money out of the operation by selling at actual cost, the profit arising from the extra shipping which is thereby attracted to the canal. The United States will reimburse the owners of any vessels passing through the locks of the canal, under the control of its operatives, for any injury which may result to vessel, cargo, or passengers. Provision is made under the permanent canal law that regulations shall be promulgated by the President which will provide for the prompt adjustment, by agreement, and immediate payment of claims. In case of disagreement, suit may be brought in the district court of the Canal Zone against the governor of the Panama Canal. The law says: "The hearing and disposition of such cases shall be expedited and the judgment shall be immediately paid out of any moneys appropriated or allotted for canal operation."
