BY S. C. BOTHWELL, MARSHAL OF SUPREME COURT. The system of imprisonment as now established in the Island is very similar to the system adopted in most of the United States. In each Municipality there is a small lock-up or hold-over in the nature of a police station, where prisoners arrested for petty offenses are first taken to await trial. In each District there is also a "Depósito Municipal" or jail, in which are confined prisoners condemned to imprisonment for less than one year. Prisoners condemned for periods exceeding that length of time are confined in the "Presidio" at San Juan, an Insular institution equivalent in character to a State penitentiary where prisoners who have been condemned to hard labor for a period exceeding one year are kept in custody.
