by Bunau-Varilla himself by mailing every Senator a Nicaraguan one-centavo stamp, showing a picture of Momotombo in spectacular eruption above the very lake through which the canal was to pass.
This turned the scales in favour of Panama. On the 19th of June, 1902, the Spooner bill passed both houses. It provided that a canal should be built across the Isthmus of Panama on condition that the French company would sell its interests and could give a clear title, and that the Department of State could make a satisfactory treaty with Colombia.
The French company agreed to sell for $40,000,000.
After the usual vacillation and subterfuges M. Herran, on behalf of Colombia, and John Hay, Secretary of State, signed a treaty which was satisfactory. It gave the United States control of the Canal zone, and Colombia $10,000,000 and $250,000 a year.
All that remained was for the Colombian Senate to ratify the treaty.
