(a) If one throws something at a wall in the street, and it lands in a
small cavity, he is Patur according the Chachamim.
On what grounds does
Rebbi Meir rule that he is Chayav?
(b) What is the Din of Tel ha'Mislaket? What sort of gradient turns it into
a Reshus ha'Yachid?
(c) What does the Beraisa say about a Mavuy which has a slope leading up or
down to a Reshus ha'Rabim?
(a) If one throws an article less than four Amos, but it rolls out, or more
than four Amos and it rolls back, in which case is one Chayav and in which
(b) Why must our Mishnah be speaking when the object did not land, and it
was the wind which blew the article in or out?
(c) The Gemara asks 've'Ha Lo Nach?'
What is the answer? Does it matter
at what height the article was halted and returned?
(d) What does the Beraisa say about an object which someone throws out into
the street, and which is caught by the wind, if the object ...
- ... did *not* stop?
- ... *did* stop?
(a) Rava says that, even when the article is within three Tefachim of the
ground, it still requires a Hanachah on something - according to the
Answers to questions
(b) Besides exempting the person who throws from one Reshus to another from
a Chatas, should the object not actually land in the second Reshus, what
other ramification will Rava's Din have - which will affect the Halachah,
even if it does go on to land in the second Reshus?
(c) Why is Rava not just duplicating what Rebbi Yochanan said earlier, when
he explained our Mishnah in the very same way?
(a) We learned above (on Daf 8b) that the reason for our Mishnah's
repetition that a pool of water in a Reshus ha'Rabim, which is less than
ten Tefachim deep, has a Din of a Reshus ha'Rabim - is to teach us the Din
both in the summer and in the winter. Abaye, in our Sugya, explains that
the Mishnah repeats itself, to tell us this Din applies even by a pool
which is more than four Amos long.
What does he mean?
(b) And what does Rav Ashi mean when he answers that is to tell us the Din
even by a pool that is less than four Tefachim long?
(c) What does Rav Ashi say with regard to throwing something on to a plank
of a bridge that is slightly apart from the other planks, setting a
precedent for his statement here?
(a) Why is one Patur for throwing from the sea on to dry land or on to a
ship or vice-versa, or from one ship to another?
(b) Why does the Mishnah prohibit carrying from one ship to another, even
when they are next to each other? What is the case?
(a) Rav Huna permits one to draw water by means of a Ziz.
What is a
Ziz, and what purpose does it serve?
(b) Why is Rav Huna so lenient in this regard?
(c) According to Rav Chisda and Rabah bar Rav Huna, a Mechitzah Teluyah is
What is a Mechitzah Teluyah? Is it also effective on land?
(d) Why are Rav Chisda and Rabah bar Rav Huna more stringent than Rav Huna?
In which basic point do they argue with him?
(a) What is is a Sefinah as opposed to Arivah?
(b) Why does Rav Huna not suspect that sometimes the ship travels in low
water, so by putting out no more than a Ziz, he will be carrying from a
Karmelis to a Reshus ha'Yachid?
(c) How about the front of the ship - which is above the water.
does Rav Huna not suspect that one might draw water from there - even when
the water is less than ten Tefachim deep, before the hull of the ship
reaches that point?
(a) According to Rav Chisda and Rabah bar Rav Huna, how did they get rid of
Why does Rebbi Yehudah need to say ...
(b) Why is there no Isur of Kocho (when something flows down a slope, after
one places it there)?
(c) Why could they not pour it out via the Mechitzah Teluyah?
(d) What proof does the Gemara bring from the statement of Rebbi Yehudah in
the Beraisa, 'Metaltelin mi'Tochah le'Yam'? How do we know that the reason
is because of the principle 'Kocho be'Karmelis Lo Gazru'?
