If a majority of the legal votes cast at the election be for the issuing of the bonds, the commissioners shall proceed at once to the issuing of same and shall deliver the bonds to the treasurer of the county, who shall be chargeable therefor upon his official bond. The treasurer, by and with the advice of the commissioners, shall proceed to sell said bonds and retain the proceeds thereof to be paid upon the orders of the commissioners as the same shall be needed: Provided, however, that said bonds shall not be sold for less than ninety-five cents ($0.95) on the dollar.
