In making the sale of drainage bonds the board of drainage commissioners shall prepare a notice of such sale containing the usual and appropriate information regarding the terms and provisions of the bonds, and shall publish the same for at least a period of two weeks in at least one paper of general circulation published within the State and in at least one other newspaper of large circulation among the buyers of bonds, in which they shall invite sealed bids from prospective purchasers to be opened on a certain day, and may require  a cash deposit to accompany all bids, and shall reserve the right to reject any and all bids. In such notice the commissioners may hold in reserve information as to the date when the first installment of principal shall fall due, the annual installments of principal to be paid, the number of years within which the serial bonds are to be paid, the form of the bonds, and the name of the bank or trust company at which the interest coupons and the installments of principal are to be made payable, and shall state that the information and data so withheld may subsequently be agreed upon between the drainage commissioners and the purchaser of the bonds; or the board of drainage commissioners in their advertisement asking bids may make optional propositions in the respects above recited, inviting bids as to each kind of bond so proposed. The board of drainage commissioners shall accept the highest bona fide bid for such bonds and issue and sell the same accordingly, provided the highest bid shall equal or exceed the par value of the bonds with any accrued interest thereon. If no satisfactory bid shall be received, the board of drainage commissioners may readvertise the bonds for sale in the manner above provided, or they may accept any private bid for the bonds at not less than their par value, with any accrued interest thereon. The board of drainage commissioners shall in good faith make diligent effort to sell the bonds at a price not less than their par value, with accrued interest. Bonds of any drainage district heretofore sold or contracted to be sold by the Local Government Commission in the manner provided by the Local Government Act, either alone or in conjunction with the board of drainage commissioners, shall be deemed to have been lawfully sold or contracted to be sold.
