The legislature added three-fourths of the net proceeds of swamp and overflowed land sales to the common-school fund.

The evidence

• “(5) five per cent, of the sale of government lands within the state. In addition to these constitutional sources of the school fund, another and sixth source was open from 1856 to 1870. By an act of the state legislature in the former year, three-fourths of the net proceeds of the sales of the swamp and overflowed lands, granted to the state by congress, Sept. 28, 1850, were added to the commonschool fund, the other fourth going into a fund for drainage, under certain circumstances ; but if not paid over to any town for that purpose within two years, to become a part of the school fund.”
