The board of directors of any such cemetery association shall appoint a trustee, who shall be a responsible businessman or some solvent federally insured banking institution, to act as such trustee for a period of two years, or until his or its, successor is appointed. Such trustee shall be known as the trustee of the permanent endowment fund of such cemetery association, and shall immediately upon his or its, appointment and acceptance of the trust, give bond to the said cemetery association, with some solvent and reliable bonding company authorized to do business in this state, in a sum equal to the amount which may come into the hands of such trustee, which bond shall be increased or diminished from time to time so as always to equal at least the amount of the trust funds in the hands of such trustee; and the premium upon such bond shall be paid out of the income of the trust funds in the trustee's hands and as part of the cost of the administration of the trust fund. No trustee appointed under this section shall enter upon the discharge of his or its, duties until such bond is given and approved by the board of directors of such cemetery association: Provided, That if the trustee so appointed by any such cemetery association be a federally insured banking institution authorized and qualified to exercise trust powers under and subject to the provisions of article four, chapter thirty-one-a of the Code of West Virginia, 1931, as amended, it shall not be required to give the bond hereinbefore provided, excepting and unless required by the provisions of section eighteen, article four, chapter thirty-one-a of said code. The board of directors of such cemetery association shall allow such trustee, for service as such, a negotiable, reasonable fee to be paid from such trust funds. In the event of a vacancy in such trusteeship, or failure of the board of directors of any such cemetery association to appoint such trustee, after being requested so to do by any stockholder of any such cemetery association, or its successor, or any citizen interested, application may be made to the circuit court of the county wherein such cemetery association is located, and it shall be the duty of the circuit court of such county to appoint a trustee, who, when so appointed and qualified, shall have all the powers and perform all the duties of such trustee as provided in this section.
