As the financial situation in Porto Rico did not permit the establishment of a completely new judicial system, it was decided to appoint the judge of each of the seven district courts of the Island to act as judge of the Juvenile Court. The prosecutors and municipal court judges are also probation officers _ex officio_, and the justices of the peace and others appointed by the district judges may be asked to serve as special probation officers. The Juvenile Courts in Porto Rico have original jurisdiction over juvenile offenders, and any case appealed from the Juvenile Courts may go directly to the Supreme Court of the Island. The courts are courts of record and the judges have authority to set the dates and places when and where sessions of the court will be held, to summon witnesses and compel them to appear in court. The jurisdiction of the Juvenile Courts in Porto Rico extends to all children under 16 years of age who are accused of any crime whatsoever, and it also applies to all people under 21 years of age, if they have ever been under the jurisdiction of the Juvenile Court before they were 16. The Juvenile Court also has jurisdiction over adults who have been responsible for the abandonment of children or who have contributed in any way to the delinquency of the child. Of course, this situation is not an ideal one for the best working out of the problems that confront a Juvenile Court system. In the first place, it is practically impossible for men who act as criminal judges or criminal prosecutors to adopt the attitude so necessary for the fulfillment of the work of a juvenile court officer, as their training has been such as to influence them to believe that the prisoner is an offender and that violations of the law must be punished with sufficient severity to prevent a repetition of the offense on the part of the prisoner, and to serve as a warning for others who might be tempted to commit the same offense. The Juvenile Court officer, on the other hand, should regard only the best future interests of the child, and the question with him should not be as to whether a proper punishment may be inflicted for what the child has done, but as to how the future conduct of the child may be bettered after a due consideration of all the influences of heredity and environment in each particular case. From July 1, 1915, to January 1, 1916, a total of 164 cases came before the Juvenile Courts. Of these, three cases were girls accused of petty larceny, and two were charged with being abandoned. The remaining 159 cases were boys. The cause given in nearly every case for the bad conduct of the children was one of the four following: 1. Lack of parental authority. 2. Bad environment. 3. Ignorance. 4. Poverty.
