(b) The city clerk shall be required to execute a good and

collector of the assessments.

(c) It shall be the duty of the city clerk to keep an accurate

account of all such collections made by him and to pay to the city

with interest, so certified to the county treasurer and all

installments, together with interest, of all assessments levied by

the board of county commissioners shall be by the county treasurer

placed upon the November delinquent tax list of the same year

prepared by the treasurer of such county, and collected as other

delinquent taxes are collected.

(e) It shall be the duty of the county treasurer to collect such

installments of assessment, together with interest and penalty, as

herein provided, but any taxpayer shall have the right to pay his ad

valorem taxes to the county treasurer regardless of the delinquency

of such assessments; and within thirty (30) days from the receipt of

such delinquent assessments, interest and penalty, so certified to

the city and so collected by the county treasurer, the same shall be

paid by the county treasurer to the city treasurer for disbursement

in accordance with the provisions of this article. Upon the receipt

of installments, together with interest or penalty, or both, of
