As the fog rolled in, the shepherd wandered the moor, hullooing to gather his scattered sheep.

The hullooing of the hunters echoed across the valley as they signaled to one another.

The hullooings from across the marsh signaled that the hunters had returned.

They hullooed for help when the old bridge began to collapse.

Every evening, the watchman hulloos across the harbor to signal the boat.

At dusk the children chased the hulloos across the meadow, laughing all the while.

They hulloo to rally the hunting party before the hounds were released.

From across the field came a hulloo that startled the horses.
