WHEN A WALL DIVIDES CHATZEROS (Yerushalmi Perek 7 Halachah 2 Daf 46a)
[ãó ð òîåã à (òåæ åäãø)] îúðé' ëåúì ùáéï ùúé çöéøåú âáåä òùøä åøçá àøáòä îòøáéï ùðéí åàéï îòøáéï àçã
(Mishnah): If a wall between two Chatzeros is 10 Tefachim tall and four Tefachim thick, the Chatzeros can be Me'arev individually but not together;
äéå áøàùå ôéøåú àìå òåìéï îéëï åàåëìéï åàìå òåìéï îéëï åàåëìéï [ãó îå òîåã á] åáìáã ùìà éåøéãå ìîèï
If there are Peros on top of the wall, these (people from this Chatzer) may alight [on the wall] and eat them, and these may alight and eat them, but they may not take them down.
ðôøõ äëåúì òã òùøä àîåú îòøáéï ùðéí åàí øöå îòøáéï àçã îôðé ùäåà ëôúç
If the wall was breached up to 10 Amos, the Chatzeros can be Me'arev individually or together, for it is like an opening;
éåúø îéëï îòøáéï àçã åàéï îòøáéï ùðéí:
If it was breached more than 10 Amos, the Chatzeros can be Me'arev together but not individually.
âî' åìîä ìé øçá àøáòä åàôéìå àéðå øçá àøáòä.
(Gemara) Question: Why must we say that it is four thick? Even if it is not four thick (the Chatzeros can be Me'arev individually but not together)!
áâéï îúðéúà äãà ãáúøä àìå òåìéï îéëï åàåëìéï åàìå òåìéï îéëï åàåëìéï
Answer: It is due to the Seifa - these may alight and eat them, and these may alight and eat them, but they may not take them down.
ìà äéä øçá àøáòä. øáé áà áùí øá àñåø ìëàï åìëàï øáé æòéøà áùí øá îåúø ìëàï åìëàï
If it is not four thick - R. Ba citing Rav said that [the wall] is forbidden here and here (to both of them). R. Ze'ira citing Rav said that it is permitted here and here.
(îçìôä ùéèúéä ãøáé áà úîï àîø øáé áà øá éäåãä áùí ùîåàì æø÷ä åðçä òì øàùé îçéöåú çééá åëà àîø äëéï úîï àú øåàä àåúä ëéìå îìéàä òôø åöøåøåú åäëà îä àéú ìê - ùòøé úåøú àøõ éùøàì îåç÷å) úãò ìê ãîø øáé àçà øáé çéððà áùí øáé éåçðï æéæéï åëúìéí ùäï âáåäéï òùøä (åøçáéï) [ö''ì åàéï øçáéï - ÷øáï äòãä] àøáòä îåúø ìëàï åîåúø ìëàï åáìáã ùìà éçìéó.
Support (for R. Ze'ira - R. Acha citing R. Chinena citing R. Yochanan): Ledges and [protrusions from] walls that are 10 [Tefachim] tall and not four wide, they are permitted here [to transfer between them and Reshus ha'Yachid] and here [to transfer between them and Reshus ha'Rabim], as long as they do not transfer [between Reshus ha'Rabim and Reshus ha'Yachid via the ledge].

Question (R. Chanan): R. Ba contradicts himself! There, R. Ba cited Rav Yehudah citing Shmuel to say that if one threw something [from Reshus ha'Rabim] and it landed on top of walls (that enclose four by four Tefachim), he is liable, and here he says so (that the top is forbidden to both of them, for it is Batel to them)?!
äéê îä ãàú àîø úîï àú øåàä àåúå ëéìå îìéàä òôø åöøåøåú àåó äëà ëï.
Just like you say there, that you view (what is within the walls) as if it were full of earth and pebbles, also here so (you should consider the ledge like part of Reshus ha'Yachid)!
ùîòðå îçéöåú áøùåú (äéçéã ùîòðå îçéöåú áøùåú äøáéí) [ö''ì äøáéí ùîòðå îçéöåú áøùåú äéçéã - îéëì äîéí, - ùòøé úåøú àøõ éùøàì]
Answer: We heard [that R. Ba views it as if it were full] regarding walls in Reshus ha'Rabim. Did we hear [that he says so] about walls in Reshus ha'Yachid?! (We explained this like SHA'AREI TORAS ERETZ YISRAEL.)
