(4) The lands thus accruing to the state shall be divided among the needy[2248] in lots, the maximal size of which seems to have been set at thirty iugera,[2249] to be held not as private property but as permanent, heritable leaseholds inalienable and subject to a specified rent.[2250] The Latins and Italians are to be included among the beneficiaries of this provision.[2251] (5) Certain specified parts of the public domain shall not be subject to assignment—the same parts which are afterward reserved from assignment by the agrarian law of 111:[2252] a. Land granted by law or by a senatorial decree to a colony, a municipium, or a Latin town, with the exception of any tracts of such land which this law may expressly order to be sold, assigned, or restored.[2253] Public domain granted by a lex or a senatus consultum can be withdrawn by the same, but the modification of a treaty requires the consent of both parties.[2254] b. The trientabula—portions of public land granted by the government for a quit rent to its creditors as security for any part of a loan.[2255] c. The ager compascuus—public land on which a specified group of neighbors have a right to pasture free of charge ten large domestic animals—cattle, horses, mules, and asses—and a fixed number of small animals, unknown to us on account of a lacuna in the inscription but most probably fifty.[2256] As the unit was doubtless the individual, much of the land of this description must have remained undivided.[2257] d. Public roads.[2258] e. Other portions of the public domain specifically designated as exempt from distribution, including the Campanian lands, which are leased out by the censors.[2259] f. Certain pasture lands let out to any who wish to feed their live stock thereon, who pay a tax (scriptura) for the privilege.[2260] (6) The distribution of the lands shall be effected by a standing magistracy elected annually by the tribes[2261]—the triumviri agris dandis adsignandis.[2262] (7) As all available public land is to be utilized in the various ways described above, and as the holders of lands once public are to be guaranteed in their possession, further occupation of land is thereby precluded.[2263]
