1)

(a)The Mishnah discusses water that overflows from vessels that have been placed at the foot of a drainpipe into a Mikvah. Why is it not Pasul anyway, due to its having flowed down the drainpipe? (see Tiferes Yisrael)?

(b)What does the Tana rule?

(c)He draws no distinction between (very) large vessels and (very) small ones. Why does he see fit to mention ...

1. ...large vessels? What is he coming to teach us? (see Tos. Yom-Tov).

2. ...small ones? [Ibid.]).

(d)He also lists vessels made of dung (or of marble), of stone or of earth. Why might we might otherwise have thought that, in all these cases, the water will remain Kasher?

2)

(a)Beis Shamai declares the water Pasul, irrespective of whether the vessel was placed there on purpose or it was forgotten there. What do Beis Hillel say?

(b)How does the Gemara in Shabbos establish the case?

(c)What is the basis of their Machlokes?.

(d)What would be the Halachah, had the owner ...

1. ... forgotten the vessels there after the clouds dispersed?

2. ... placed the vessels there before the clouds gathered?

3)

(a)According to R. Yossi, the Machlokes between Beis Shamai and Beis Hillel was never resolved. What does R. Meir say? (see Tos. Yom-Tov).

(b)Like whom is the Halachah? (see Tos. Yom-Tov).

(c)What does the Mishnah rule in a case where the owner forgot the vessels (not under a drainpipe, but) in the middle of the Chatzer? (see Tiferes Yisrael).

4)

(a)Now the Mishnah discusses a board that is placed at the foot of a drainpipe. Why was it placed there? (see Tos. Yom-Tov)?

(b)On what condition is the water not considered Mayim She'uvin?

(c)What does the Tana say where the owner stood up the board to drain, but water from the drainpipe still managed to reach the Mikvah via it?

(d)Why is that? (see also Tos. Yom-Tov).

5)

(a)On what grounds does the Tana rule that water flowing through a regular pipe is not Mayim She'uvin?

(b)What must one do to the pipe in order to render the water Mayim She'uvin from now on?

(c)This ruling must be confined to a pipe that was carved out before being fixed. Why is that?

(d)What if it is fixed before being carved?

6)

(a)The smallest cavity in a wooden pipe renders the water Mayim She'uvin. What does the Tana Kama say about an earthenware one?

(b)Why is that?

(c)R. Yossi is more stringent. What does he say?

(d)According to him, in what connection was the Revi'is that the Tana Kama heard, said?

(e)Like whom is the Halachah?

7)

(a)The Mishnah discusses what the Din will be if, in the aforementioned cavity, there are Tzeroros ha'Mischalchelin (pebbles that roll around) or Afar ha'Nechbash. What is Afar ha'Nechbash? (See Tos. Yom-Tov).

(b)What does the Tana say about ...

1. ... Tzeroros ha'Mischalchelin?

2. ... Afar ha'Nichbash?

(c)Why the difference?

8)

(a)The Tana, discussing a pipe that is narrower at the ends and wider in the middle, forming an automatic cavity, switches here from Tzinor to Si'lon. What is the basic difference between a Tzinor and a Si'lon? (see Tos. Yom-Tov DH 'ba'Tzinor').

(b)What does he say about a Si'lon?

(c)Why is that? (see Tos. Yom-Tov).

9)

(a)If Mayim She'uvin and rain-water mix in the Chatzer before falling into a large pit (making up forty Sa'ah), on what condition will the Mikvah be ...

1. ... Kasher"

2. ... Pasul?

(b)How much rain-water is considered a majority (see Tos. Yom-Tov).

(c)What if it comprises half of each?

(d)What does the Tana say if the two mix ...

1. ... on the steps leading to a cave

2. ... in an Uka?

(e)What is an Uka?

10)

(a)Until now, the Tana has been speaking about the two waters that mix before flowing into the pit. What if the Mayim She'uvin falls into rain-water that is already in the pit?

(b)And what if twenty-one Sa'ah of Mayim She'uvin falls into nineteen Sa'ah of rain-water via Hamshachah (it first flows three Tefachim along the ground) see Tos. Yom-Tov?

11)

(a)What is the Mishnah referring to when it disqualifies water that one draws from a trough (see Tiferes Yisrael) that is carved into a rock?

(b)The Tana also disqualifies the trough itself from Kidush. What does he mean by that?

(c)What else may one not do with the Mei Chatas that one poured into it?

(d)What is the reason for the two latter rulings?

12)

(a)What does the Tana mean when he adds ve'Einah ...

1. ... Tzerichah Tzamid Pasul?

2. ... Poseles es ha'Mikvah?

(b)On what condition...

1. ... is the trough considered a vessel in all the above regards?

2. ... will a vessel subsequently lose its status of K'li (and not render the water in it Mayim She'uvin)?

(c)Whereabouts must the leak be? (see Tos. Yom-Tov)?

(d)What size must it be? (See Tos. Yom-Tov).

(e)What size must the hole in the wall between Mayim She'uvin in one pit and a full Mikvah in an adjoining one, in order to become Bateil to it (and therefore be considered a Kasher Mikvah)?

13)

(a)R. Yehudah ben Beseira relates an episode regarding Shokes Yeihu in Yerushalayim. What was Sho'kes Yeihu'?

(b)What was its irregular feature?
