(c)Why can he not be talking about an Eiruv Chatzeiros?

(d)The two exceptions listed by the Mishnah are water and salt. Which other two foods are included in the list of exceptions?

(e)The Tana omits them based on the principle - that 'One cannot learn from principles, even where the Tana specifically says "Chutz" '?

(f)On what grounds are these items not eligible (See Tos. Yom-Tov)?

(c)Why is that?

3)

(a)And if somebody makes a Neder to desist from Mazon, what are the two sole exceptions?

4)

(a)What does Sumchus say about making an Eiruv for a Yisrael with Terumah?

7)

(a)What do the Rabbanan hold with regard to making an Eiruv in a Beis-ha'Kevaros on behalf of a Yisrael?

(b)Then why do they argue specifically by a Kohen?

(c)Seeing as it is forbidden to derive benefit from a Beis-ha'Kevaros, how can Rebbi Yehudah permit placing an Eiruv there?

(d)Bearing in mind that the Eiruv takes effect Bein-ha'Shemashos (with the entry of Shabbos), the Machlokes is based on the fact that the Eiruv generally in the guarded spot that he placed it, after that time. What in fact, is now the basis of the Machlokes?

(a)The Tana permits making an Eiruv with 'D'mai, Ma'aser Rishon whose Terumah has been taken (she'Nitlah Terumaso), Ma'aser Sheini and Hekdesh that have been redeemed and for Kohanim with Chalah and Terumah (See Tos.

(b)What does the Tana mean when he says 'Ma'aser Rishon she'Nitlah Terumaso'?

12)

(a)On what grounds does the Mishnah declare invalid an Eiruv that one places on a tree in the R'shus ha'Rabim above the height of ten Tefachim?

(b)Why can one not simply leave the Eiruv where it is?

15)

(a)The next case on the Tana's list is where the Eiruv is placed atop a cane or a tall pole that is stuck in the ground but not attached it, even if it is a hundred Amos tall. Why would the Eiruv be invalid if it was simply hung on top of the pole?

(b)What is then the case?

(c)On what grounds is the Eiruv then valid? Why would he be permitted to take the Eiruv even on Shabbos?

16)

(a)What would be the Din if the cane was still attached to the ground?

(b)Assuming that the prohibition is based on the fear that one may cut the top of the cane when taking the Eiruv, why would that be a problem? Which Melachah does it involve?

20)

(a)How deep must the pile of stones that fell on the Eiruv be to invalidate the Eiruv?

(b)Having taught us the Din regarding the Eiruv ...

1. ... that rolled outside the T'chum, why does the Tana need to then add the case where a pile of stones fell on it?
