You could save a vast tract of rainforest, you could feed the starving.

Poaching and invasive species of plants were degrading the area and the state did not want to provide the money to maintain the vast tract.

A vast tract of land was deserted and perhaps 200,000 inhabitants of the neighbouring districts of the lines were relocated inside the lines.

In the last few years, a property developer bought a vast tract of vacant, government land.

In this vast tract of land.... every sort of produce and improvement of which the various soils of the earth are capable, may be expected.
