The principal sum paid for the care of any lot in Dodge Grove Cemetery, either from the sale price or by donation, shall, as soon as sufficient amount has accumulated, be invested. A pro rata part of the yearly income of the aggregate fund shall be expended for the care of such lots. A list of all such lots shall be kept by the Superintendent and it shall be his duty to report from time to time, to the Board of Managers, in writings, the condition of every lot needing or requiring attention. The repairing of monuments, vaults and other structures on a lot can be provided for only by special contract in each case, with the Board of Managers.
