The rota was a cylinder, open on one side, that was built inside a wall of a monastery; it was used for exchanging mail and food with cloistered clergy, being their only communication with the world. It was usually about 50 centimeters wide by 30 centimeters high, and its opening did not permit visual or tactile contact with the uncloistered. Messages or food were put into the cylinder, then the rota was revolved so that the opening faced the other side. Monks were stationed close by or were notified that someone had turned the wheel by various mechanisms. In some cases, especially at night and in winter, the rota was filled by the monks with food, and left there for the poor, to give them something to eat without them having to ask. The rota was also used by those mothers who didn't want to (or couldn't) keep their (often illegitimate) newborn babies. They left them in the safe hands of monks or nuns, their anonymity being guaranteed by the rota. In some dioceses the instrument was abolished to discourage this latter use.
works of architecture properly so called these elements must exist, and be harmoniously combined.
evolution of the art of architecture will be considered in various sections, associated with the nations and periods from which the leading historic styles are chronologically derived, in so far as the dominant influences on the art, and not the purely local characteristics of countries outside the See also:
section on what can only be collectively termed Modern architecture deals with the main lines of the later developments down to the present day in the architectural history of different countries.
Rota was the only major island in the Mariana Archipelago to be spared the destruction and land use changes brought about by World War II and its aftermath.
Rota's limestone forest provides and sustains habitat for endangered bird species, a threatened species of fruit bat, and numerous species of invertebrates that are proposed for listing as threatened or endangered.
Since those lands on Rota found to contain resources of national significance and also found to meet the test of suitability are now in public ownership, acquisition of a less-than-fee-interest by the NPS is judged to be feasible-so long as that interest is long-term and achieved at no cost to the federal government.
