520 INMATES SHUN WORK AT RAHWAY

RAHWAY, N. J., June 26 — The superintendent's office at the state's maximum‐security prison here reported that 520 of the institution's 820 inmates refused to work today in the shops to which they had been assigned, although all appeared for their meals in the prison mess hall.

In what was understood to be a “peaceful demonstration,” the prisoners sat quietly in their cells during the day, leaving only to eat breakfast, lunch and supper.

A list of demands for changes in the state's parole regulations was found posted last night on the inmates' bulletin board, prison officials said. The message was not addressed to anyone, nor was it signed by anyone the offi cials added.

They said they had been told by some inmates that the demonstration was planned as a “peaceful one” and that it would continue until the de mands on parole changes had been met.

The demands included auto matic parole at the date of eligibility rather than by de cision of the Parole Board, elimination of the classification “multiple offender” and “no loss of street time” in the cases of parolees arrested and returned to the prison for of fenses charged against them while free on parole. A prisoner returned from parole in such cases automatically has the credit for his time served re vert to the day his parole be gan.

A spokesman for the Division of Institutions and Agencies, which operates the state's pris ons, said that the work stop page was being studied in the light of potential penalties, but that no decision had been reached. He added that changes in the parole system were understood to be the concern of the Legislature, which writes the laws under which the Parole Board operates.

The office of the super intendent said the remaining 260 inmates assigned to prison tasks went about their work today unhindered by the strik ing inmates.

The prison here was the scene of a violent rebellion last November when hostages were seized, fires were set and parts of cellblocks were dam aged in protest against what the inmates called intolerable conditions within the prison.
