of a permit to do so, within any F, G, H or J district within the city as shown by

manner required for the granting of variances generally, the city commission may authorize
the conducting of carnivals, festivals and circuses in E districts as well as in F,
G, H and J districts, but no variance shall be issued to carnivals, festivals or circuses
to be operated in any other zoning district.
