As however, apart from the conversion of the public land into private property or its assignation, Roman law knew no fixed rights of usufruct on the part of individual burgesses to be respected like those of property, it depended solely on the pleasure of the king, so long as the public land remained such, to grant and to define its joint enjoyment; and it is not to be doubted that he frequently made use of his right, or at least his power, as to this matter in favour of plebeians.

But on the introduction of the republic the principle was again strictly insisted on, that the use of the common pasture belonged in law merely to the burgess of best right, or in other words to the patrician; and, though the senate still as before allowed exceptions in favour of the wealthy plebeian houses represented in it, the small plebeian landholders and the day-labourers, who stood most in need of the common pasture, had its joint enjoyment injuriously withheld from them.

Moreover there had hitherto been paid for the cattle driven out on the common pasture a grazing-tax, which was moderate enough to make the right of using that pasture still be regarded as a privilege, and yet yielded no inconsiderable revenue to the public purse.

The patrician quaestors were now remiss and indulgent in levying it, and gradually allowed it to fall into desuetude.

Hitherto, particularly when new domains were acquired by conquest, allocations of land had been regularly arranged, in which all the poorer burgesses and -- metoeci-- were provided for; it was only the land which was not suitable for agriculture that was annexed to the common pasture.
