Moneys in the normal school income fund shall be used for the benefit of the beneficiaries of the endowment and distributed to current beneficiaries of the normal school endowment pursuant to legislative appropriation. However, not more than fifty percent (50%) of earnings of the normal school income fund shall ever be appropriated for the support and maintenance of either Lewis-Clark State College or the department of education at Idaho State University.
