7.  Group juries may, on the recommendation of the chiefs of their respective departments, and with the approval of the director of exhibits, have authority to appoint, as associates or experts, one or more persons especially skilled in matters submitted for examination.  These experts shall participate only in such special work as they are selected to perform and shall have no vote on the question of the merit of the exhibit under consideration.

8.  Each group jury shall carefully examine all exhibits pertaining to the group to which it has been assigned.  It shall also consider and pass upon the merits of the collaborators whose work may be conspicuous in the design, development, or construction of the exhibits.

The jury shall prepare separate lists presenting the names of such exhibitors as are out of competition, awards recommended to exhibitors in order of merit, awards recommended to collaborators in order of merit, a report giving an account of the most important objects exhibited, and a general account of the group as a whole.

These papers shall be certified to the chief of the department to which the group belongs, and the chief of the department shall certify the same, with such recommendations as he may deem advisable, to the department jury.

    9.  In order to expedite their work group juries may be divided
    into committees for the examination of exhibits.

These committees shall be governed by paragraphs 1, 2, and 3 of rule 8, just cited; when they have completed the work assigned them they shall report to the full jury, which shall review the findings after an inspection of all the exhibits in the group.

    10.  When the exigencies of the work require such procedure, and
    when recommended by a chief of a department and approved by the
    director of exhibits, two or more group juries may be combined.

11.  In the case of temporary exhibits and such other exhibits as are developed through a considerable period of time, or which for other reasons can not be governed by the time limits prescribed, the juries of such groups may continue in service throughout the entire period of the exposition.  Special juries may be formed when urgently needed for special occasions.

At the close of each temporary exhibit or competition the jury having the same in charge shall prepare a list of awards proposed in order of merit and shall certify the same to the chief of the department to which the exhibit pertains.

Special awards for such temporary exhibits or competitions may be provided by the chief of the department to which the exhibits belong, on the approval of the director of exhibits and the president of the Exposition Company.

12.  Each department jury shall be composed of the chairman and vice-chairman
