When the exhibition buildings and facilities are not in use for state fair purposes, the commissioner of agriculture and markets may manage and lease such exhibition buildings and facilities and may lease space in such buildings, and may execute contracts in relation to such rentals and fix, impose and collect rentals and license fees therefor. All rental and license fees and such other income as may be provided by the leasing of such buildings, space and facilities shall be considered moneys payable to the state on account of said fair in accordance with the provisions of § 31-C (Receipts and disbursements)section thirty-one-c of this article. The commissioner of agriculture and markets may convey to the industrial exhibit authority certain real property in the town of Geddes, Onondaga county, New York, as heretofore or hereafter acquired by the state for state fair purposes. The commissioner is authorized to execute and file in the Onondaga county clerk’s office an instrument in writing defining specifically the plot or plots of land transferred to the industrial exhibit authority pursuant to this section provided, however, that such plot or plots of land shall be no more than is sufficient to accomplish the purposes described in the instrument. When such written instrument is so filed it shall vest the authority with the title to the real property defined therein provided, however, that nothing herein shall prevent the industrial exhibit authority from transferring back to the state and vesting title in the state for state fair purposes under the management and control of the department of agriculture and markets any land which the authority heretofore received as state fair land or any state fair land which the authority may hereafter receive pursuant to this section. In the event that the industrial exhibit authority shall be abolished or for any reason cease to exist the title to all lands held by the authority which were formerly state fair lands shall revert to the state for state fair purposes under the management and control of the department of agriculture and markets. All conveyances heretofore made between the commissioner of agriculture and markets and the industrial exhibit authority are hereby confirmed and recognized as valid and sufficient to convey good title. The maintenance and repair of the improved roads on said property shall however be under the direct supervision and control of the superintendent of public works who is hereby authorized and directed to maintain and repair the same, and the cost of such maintenance and repair shall be paid out of any funds available for the maintenance, repair and reconstruction of improved state highways.
