Not less than fifteen percent of the tax imposed for severing coal shall

in trust and administered by the board of university and school lands,
which shall have full authority to invest said trust funds as provided
by law, and may loan moneys from the fund to political subdivisions as
provided by law. The interest earned on the moneys in said trust fund
