When the Hepburn bill came up for discussion in the Senate, the situation had thus been radically changed, and a long debate ensued as to the relative merits of the two routes. Senator Morgan continued to fight for Nicaragua as the traditional American route, declaring that the Panama Company could not give a valid transfer of its property and interests. But this objection was cleverly met by Senator Spooner, who offered an amendment, which was virtually a substitute, authorizing the President to acquire the rights and property of the French company at a cost not exceeding $40,000,000; to acquire from the Republic of Colombia, upon such terms as he might deem reasonable, perpetual control of a strip of land, not less than six miles in width, extending from the Caribbean Sea to the Pacific Ocean, with jurisdiction over said strip; and to proceed as soon as these rights were acquired, to construct a canal. But should the President be unable to obtain a satisfactory title to the property of the French company and the control of the necessary strip of land from the Republic of Colombia "within a reasonable time and upon reasonable terms," then he was instructed to secure control of the necessary strip through Nicaragua and to proceed to construct a canal there. The bill as amended passed the Senate June 19, 1902, by a vote of 67 to 6. The House at first refused to concur in the Spooner amendment, but after a conference it finally gave way and the measure was adopted by a vote of 260 to 8. The act was signed by President Roosevelt June 28.[186] Attorney-General Knox was sent to Paris to make a thorough investigation of the affairs of the Panama Company. He reported that it could give a clear title. The next step was to secure a right of way through Colombia. After considerable delay Secretary Hay and Mr. Herran, the Colombian charge d'affaires, signed, January 22, 1903, a canal convention, by the terms of which the United States agreed to pay Colombia $10,000,000 in cash and an annuity of $250,000 for the lease of a strip of land six miles wide across the isthmus. Objection was raised to this treaty because it failed to secure for the United States full governmental control over the canal zone, but it was considered the best that could be gotten and it was ratified by the United States Senate March 17, 1903.
