opposite sides of the street, when gentiles built two Mechitzos on Shabbos,
blocking off the street at both ends, to form a courtyard joining the two
(b) Why is this no Sha'aleh according to those who hold that Bitul Reshus
does *not* help from one Chatzer to another?
(c) What then, is the Sha'aleh (according to those who that it *does*?
(d) How did Rav Sheshes resolve the Sha'aleh?

Why does Rav Hamnuna disagree?
(a) A gentile who owns a small doorway leading from his house in the Mavoy
out to the fields, does not forbid the other Jewish residents of the Mavoy
to carry there.
Why is that? Does it apply even if he uses the Mavoy

(c) Some say that this applies even to a case where the entrance leads out
to a mere Karfaf.
What do Rabah and Rav Chisda say about that?

by a gentile, *is* Chashuv by a Jew?

less than ten Tefachim high and which has an area of more than a Beis
(b) What does the Beraisa therefore mean when it writes 'Ad Kamah, Ad Beis
Sasayim', and why does this leave us with a Kashya on Rebbi Yochanan?
(c) Rava establishes the statement ('Ad Kamah, Ad Beis Sasayim') on the
Reisha (with regard to a rock that *is* ten Tefachim high, by adding to the
Beraisa, in a way that dispenses with the Kashya.
How does he do this?
(d) Rav Ashi goes one step further - he leaves the Beraisa intact; and in
spite of this, he vindicates Rebbi Yochanan.
According to him, why is it
forbidden to throw four Amos on the surface of a Karfaf that is more than a
Beis Sasayim, but permitted Lechatchilah to throw from the sea on to a rock
that is higher than ten Tefachim and more than a Beis Sasayim?
(a) The hot water to wash the baby after the B'ris spilt.
