Now, therefore, you, and each of you, are hereby notified to contribute your proportionate share of such expenditures, to-wit, each of you the sum of $25.00, and unless you each pay to the undersigned the sum of Twenty-five Dollars within Ninety (90) days from the receipt of this notice, the interest and right of such of you as shall fail or refuse to contribute your proportionate share of such expenditures, within the time specified as aforesaid, shall be forfeited and become the property of the co-owners as shall have made the required expenditures and contribution in accordance with the provisions of Section 2324 of the Revised Statutes of the United States.
