751. Carrying Into or Out of a Well's Enclosure

Shabbos 17:32

If a person was drawing water for an animal that stood between the walls of the enclosure, he may draw the water and put it in front of the animal in the vessel that was used to draw it. If an animal was in a stall ten handbreadths tall (about 30”) and four handbreadths by four handbreadths wide (about 1’x1’) and the front of this stall extended inside the walls of such an enclosure, he should not draw water and place it in front of the animal out of concern that the stall may break and he may come to carry the bucket of water into the stall, and from there to a public domain. In such a case, one should draw water and pour it in front of the animal, who will drink it by itself.

If a person throws something from a public domain into an area enclosed by walls of this kind, he is liable for transporting. Since there is an actual wall ten handbreadths tall and more than four handbreadths by four handbreadths in each corner, the enclosed square is clearly delineated and considered a private domain. This even applies when such an enclosure is used in a valley with no well involved since there is a wall on each side of each corner. Even if many people pass through this enclosure, it does not invalidate the status of the walls; it is like a courtyard through which many people pass without affecting its status as a private domain. One who throws something into such a courtyard is certainly liable for transporting. If there is a well inside such an enclosure, the Sages permitted drawing water for an animal.
