The Governor may, upon the recommendation of the State Forestry Commission, accept gifts of land to the state, the same to be held and administered by the State Forestry Commission as state forests and to be so used as to demonstrate the practical utility of timber culture. Such gifts must be absolute, except the mineral and mining rights over and under said lands (but no reservation of any timber rights in connection therewith) may be reserved and except for a stipulation that they be held and administered as state forests; and the Attorney General shall see that all deeds of gift or other grants to the state of land mentioned above are properly executed and convey good title before the gift is accepted.
