SANTO DOMINGOAN CANNON.
When Columbus was made a prisoner in Santo Domingo, the governor, who arrested him, feared there might be an attempt at rescue, so he trained a big gun on the entrance of the citadel, or castle, in which Columbus was confined. That cannon laid in the same place until Mr. Ober, a World's Fair representative, recovered it, and, with the permission of the Governor of Santo Domingo, brought it to the United States. It is on exhibition at the World's Fair.
