The director of public service shall determine the size and price of cemetery lots, the terms of payment therefor, and shall give to each purchaser a receipt, showing the amount paid and a pertinent description of the lots sold. Upon producing such receipt to the proper officer, such purchaser shall be entitled to a deed for the lots described therein.
No more shall be charged for lots than is necessary to reimburse the city for the expense of lands purchased or appropriated for cemetery purposes, and to keep in order and embellish the grounds. Provision shall be made for the interment in such cemetery of persons buried at the expense of the city.
