After receipt of said notice of bond issues and contracts with the United States it shall be the duty of the county auditors of each county in which any of such district lands are located to furnish the board of county commissioners at or before its meeting on the second Monday in September, a statement showing the amount of the annual payment on said bonds or contract and the amount of interest thereon which will fall due during the next ensuing year should the board of directors adopt such a resolution. It shall be the duty of the board of county commissioners, or boards of county commissioners of the county or counties in which such district lands are located to levy on the lands in said district the tax necessary to meet the annual payment on said bonds or contracts and the interest thereon as they become due. If said district includes lands in more than one county, the board of county commissioners of each county shall levy upon the district lands in that county the proportionate part of the total tax necessary to meet the annual payment on said bonds or contract and the interest thereon as they become due, in the proportion that the benefits apportioned to the district lands in such county are of the total benefits of such bond issue or contract apportioned to all the lands of the district, and whether the district be one or more than one county, the levy upon each of the several tracts of district lands for the payment of the annual instalments on said bonds or contract and the interest thereon shall be in proportion to the apportionment of benefits of such bond issue or contract and apportioned among the several tracts of land in the district in like manner as provided by law with reference to similar levies made by the boards of directors of irrigation districts. The county auditor of each county in which such district lands are located shall each year enter upon the county assessment roll against the property therein described the levy so made by the board of county commissioners, in manner similar to that in which school or other municipal or road district assessments are entered by him on said assessment roll, except that the sum assessed and charged against each description of land therein contained for such irrigation district purposes shall be entered by the auditor as the bond or contract assessment of the …. irrigation district against the same. Such district bond or contract tax shall be collected and accounted for by the county officers in the same manner as other municipal taxes and the collection thereof shall be enforced in the same manner, and neglect to pay the same shall be subject to the same penalties as the other taxes of the county and the same shall be paid over to the state treasurer who shall act as treasurer of the district for the purpose of receiving and depositing such funds and disbursing the same in payment of the district’s bond and United States contract obligations and the interest thereon.
