Section 4. Cities shall have power to donate ground thus acquired for a public library to any library association provided said association will furnish the funds for the erection of the library building the plans of which are approved by the city, but only in such cases where the said library association is by its by-laws and charter compelled to put back into the property any surplus earnings from the operation of said library. Cities, by order of council or commissioners, may contribute from time to time towards the operating support of such library a sum not to exceed fifty per centum (50%) of the annual operating maintenance of said library.
