visitor shall have the right to interview privately any prisoner or
inmate confined in any such jail, penitentiary, or other penal or
reformatory institution, and for that purpose to enter the cell,
room, or apartment wherein any such prisoner or inmate shall be
confined: Provided, however, That if any warden, manager, overseer,
superintendent, or person in charge of such institution at the time of
such visit, shall be of the opinion that such entry by the official

would be dangerous to the discipline of the institution, then and in
that case the said warden, superintendent, overseer, manager, or person
in charge, may conduct any prisoner or inmate, with whom such official
visitor may desire a private interview, into such other cell, room, or
apartment within the institution as he may designate and there permit
the private interview between the official visitor and such prisoner
or inmate to take place: Provided further, however, That no official
visitor shall have the right or power of privately interviewing any
such prisoner or inmate except prisoners or inmates of the same sex as
