Legislature with its findings and conclusions by the end of the second Legislative session. The Commission concluded that Arizona should not sell its Trust land outright, as other states had done. Instead, it should put the lands to their "highest and best use." The decision to sell or lease the land should be based upon the potential use of each parcel. The Commission recommended the creation of a permanent State Land Department "...in order that the multitudinous detail attached to the State’s varied land interests may have constant attention and to prevent irretrievable loss."

Quantity Grant Selections The State selected the specified acreage of Federal lands for the County Bonds and each of the individual institutional Trusts. Land Exchanges After acquiring title to the Trust lands, the State traded many of the lands for other Federal or private lands of equal value in order to relocate and block up Trust land holdings.
