No person unless under permission as hereinafter provided, shall remove, transport, or carry through the streets, alleys and other public ways of the City any table and kitchen waste, offal or dead animals. The Municipal Administrator is hereby authorized to grant permission to any person for the purpose of collecting and removing table and kitchen waste, offal and dead animals. For the collection and removal of such waste and refuse, however, the person so authorized shall provide for each wagon or truck a cover which, in the judgment of the Municipal Administrator, is sufficient to prevent the spilling of refuse and waste and the escape of obnoxious odors therefrom. The Municipal Administrator has the right to rescind at any time any permit, when, in his judgment, it will be to the interest and welfare of the City to do so.
