Siman - Shabbos Daf 8

• Reed basket (כוורת) is a reshus

Abaye said: If one throws a reed basket into a reshus harabim and the basket is ten tefachim high but not six tefachim wide, he is liable. But if the basket is six tefachim wide he is exempt because he has not transferred an “object” but rather a “domain.”

Rava said that even if the object is less than six tefachim wide is exempt, because it is impossible that some slivers of the basket do not extend up above ten tefachim resulting in some of the basket in a makom petur. To be liable for transferring one must place the object within the domain.

(Abaye considers the slivers of basket that extend above ten tefachim as insignificant).

• Nine tefachim post in reshus harabim

Ulla said: If there is an post nine tefachim high in a reshus harabim and the public uses it to adjust their burdens on it, if one threw an object four amos away and it landed on the post, the person is liable since the top has the status of a reshus harabim.

He explains that if an object in reshus harabim is less than three tefachim high, people tread upon it and therefore is considered part of the reshus harabim.

If the object is between three and nine tefachim high the public neither treads upon it nor uses it to adjust their burdens on it so it is either a karmelis or a makom petur depending on whether it is four tefachim wide or less.

• Toppling a bundle of reeds

Rav Yehuda said: If one lifts one end of a bundle of reeds (זירזא דקני) from the ground and topples it forward, then lifts the second end from the ground and topples it forward, and does this numerous times until the basket has been moved four amos in a reshus harabim, he is not liable until he lifts both ends of the bundle simultaneously and transports it four amos.

It is not considered an עקירה until both ends have been lifted from the ground simultaneously.
