Whenever funds are available for the payment of notes issued under the provisions of this Division the County Treasurer shall transmit same to the bank designated in the note as the place of payment together with written advice that funds are available to pay particular notes, designating same in numerical order, and that same will cease to bear interest fifteen (15) days subsequent to the date of such notice, and such bank shall pay accordingly. The County Treasurer shall take receipt from the bank for such remittance and thereafter such Treasurer shall be relieved of responsibility in connection therewith, a copy of which notice shall be published once by the County Treasurer in a newspaper published in the County at least five (5) days prior to the date fixed for redemption. A copy of such notice shall be mailed to any holder or owner of such notes or agent thereof, requesting same in writing. Notes may state on their face that they will not be subject to call on or before a date fixed in the resolution by the Board but which date shall be approximately the date on which it is anticipated the first tax collections will be received by the County Treasurer. When notes are payable at the office of the County Treasurer he shall set aside funds for payment of notes instead of remitting to a bank and give notice of redemption as above provided, and pay accordingly.
