Watering trough

In Australia, the watering trough is established so that sheep, cattle and other domesticated animals can drink, but native species such as kangaroos may be attracted.

One design is the "Finlayson Trough", which uses a low-lying electrified wire that sheep usually step over but kangaroos cannot.

[1] Watering troughs were very common in many towns and cities as a means for horses to drink while they were tethered to a post.

In 1927 animal lovers, Annis and George Bills, funded the building of up to 500 watering troughs in Australia, Ireland, England and the United States.

In stonemasonry, as an old or obsolete term, an abreuvoir is a joint or interstice between two stones, to be filled with mortar by a stonemason.
