By the opening years of the eighteenth century (1701), the assembly of Virginia had reached the conclusion that settlement would be the best means of protecting the frontiers, and that the best way of "settling in co-habitations upon the said land frontiers within this government will be by encouragements to induce societies of men to undertake the same."[85:2] It was declared to be inexpedient to have less than twenty fighting men in each "society," and provision was made for a land grant to be given to these societies (or towns) not less than 10,000 nor more than 30,000 acres upon any of the frontiers, to be held in common by the society. The power of ordering and managing these lands, and the settling and planting of them, was to remain in the society. Virginia was to pay the cost of survey, also quit-rents for the first twenty years for the two-hundred-acre tract as the site of the "co-habitation." Within this two hundred acres each member was to have a half-acre lot for living upon, and a right to two hundred acres next adjacent, until the thirty thousand acres were taken up. The members of the society were exempt from taxes for twenty years, and from the requirements of military duty except such as they imposed upon themselves. The resemblance to the New England town is obvious. "Provided alwayes," ran the quaint statute, "and it is the true intent and meaning of this act that for every five hundred acres of land to be granted in pursuance of this act there shall be and shall be continually kept upon the said land one christian man between sixteen and sixty years of age perfect of limb, able and fitt for service who shall alsoe be continually provided with a well fixed musquett or fuzee, a good pistoll, sharp simeter, tomahawk and five pounds of good clean pistoll powder and twenty pounds of sizable leaden bulletts or swan or goose shott to be kept within the fort directed by this act besides the powder and shott for his necessary or useful shooting at game. Provided also that the said warlike christian man shall have his dwelling and continual abode within the space of two hundred acres of land to be laid out in a geometricall square or as near that figure as conveniency will admit," etc. Within two years the society was required to cause a half acre in the middle of the "co-habitation" to be palisaded "with good sound pallisadoes at least thirteen foot long and six inches diameter in the middle of the length thereof, and set double and at least three foot within the ground."
