Section 7
SEC. 7. The proceeds of the sale of the tickets in each drawing shall be divided into three parts: Ten per centum for administration expenses, thirty per centum for charitable and public purposes, and sixty per centum for prizes. Unsold tickets shall not be included in the drawing, and prizes not collected within one year after the drawing shall accrue to the part for charitable purposes; but if not all the -tickets issued for a drawing are sold, the parts for charity and administration expenses shall be reduced proportionally in order that the prizes announced in the prospectus may remain intact.
