The State has various schemes, subject to county local option, as to working the rural public roads. Various ages are prescribed as to persons subject to road duty under these different schemes. See Wright v. Sheppard, 5 Ga. App. 298 (63 S. E. 48), and citations'. None of these enactments relate to the working of streets in towns and cities. As to this the municipal charter in each case controls. Judgment affirmed.
