him, or to the arbitrators selected under the aforesaid provi-
sions, shall be deemed confidential and so treated, and all
documents and testimony taken shall be filed in the office of
the Department of Labor and Industry.

12. It shall be the duty of the Commissioner to do all in
his power to promote the voluntary arbitration, mediation
and conciliation of controversies and disputes between em-
ployers and employes, and to avoid resort to lockouts, boy-
cotts, black lists, discriminations and legal proceedings in
or arising out of such controversies and disputes and matters
of employment. In pursuance of this duty, the said Commis-
sioner may, whenever he deems advisable, but subject to the
approval of the Governor, appoint boards of arbitration for
the consideration and settlement of such controversies and dis-
putes, and may provide for the necessary expenses of such
arbitration boards and for such reasonable compensation to
the members serving thereon as the said Commissioner may
deem proper, not exceeding, however, the sum of five dollars
per day for each member for each day during which such mem-
ber is engaged in work upon said arbitration boards. The said
Commissioner shall prescribe rules of procedure for such arbi-
tration boards, and the said arbitration board shall have the
power to conduct investigations and hold hearings, to summon
witnesses, and enforce their attendance through the ordinary
processes of law in the cities and counties in which such arbi-
tration boards may meet, subject to all the penalties for non-
attendance to which witnesses in ordinary civil cases are sub-
ject, and in like manner may require the production of books,
documents and papers and may administer oaths, all to the
same extent that such powers are possessed and exercised by
the civil courts of the State; and said arbitration boards shall
make, report and publish findings for the settlement of such
controversies and disputes. The said Commissioner shall himself
have like power to conduct investigations and hold hearings,
summon and enforce the attendance of witnesses, administer
oaths, require the production of books, documents and papers,
and make and publish reports and findings with respect to any
and all matters covered by this section. Subject to the approval
of the Governor, the Commissioner may appoint and designate
a Deputy, and fix his compensation, who shall be known as the
Chief Mediator, and who, together with any assistants who
may be assigned by the Commissioner, shall have in charge
the execution of the provisions of this section, under the direc-
tion and supervision of the Commissioner. The Chief Media-
tor may act upon any Board of Arbitration, but in such event
he shall receive no compensation therefor in addition to his
ordinary salary. Nothing in this section contained shall affect
