709. A Pole in the Public Domain

Shabbos 14:18

If a person throws an object onto a reed with a basket on top that is stuck in the ground of a public domain, he is not liable because a public domain only extends to ten handbreadths in height (about 30”). Let’s say that someone throws something like fat or dough in the public domain and it comes to rest by sticking to a wall. If it does so above ten handbreadths, it’s like he threw the object into the air because more than ten handbreadths above a public domain is a makom patur (exempt area); below ten handbreadths, it’s like he threw the object on the ground, for which he is liable. If he threw the object over ten handbreadths and it came to rest in a hole of insignificant size, he is not liable.

Shabbos 14:19

If one throws a reed or a spear from a private domain and it becomes planted vertically in the ground of a public domain, he is not liable because part of it is in a makom patur. If a one throws utensil that is four handbreadths by four handbreadths in area (about 1’x1’) and ten handbreadths high (about 30”), he is not liable because the utensil itself is a private domain. Accordingly, the one who threw it is treated as a person who transfers something from one private domain to another.
