Talmud for Bava Batra 2:7
מַרְחִיקִין אֶת הָאִילָן מִן הָעִיר עֶשְׂרִים וְחָמֵשׁ אַמָּה, וּבְחָרוּב וּבְשִׁקְמָה חֲמִשִּׁים אַמָּה. אַבָּא שָׁאוּל אוֹמֵר, כָּל אִילַן סְרָק, חֲמִשִּׁים אַמָּה. אִם הָעִיר קָדְמָה, קוֹצֵץ וְאֵינוֹ נוֹתֵן דָּמִים. וְאִם הָאִילָן קָדַם, קוֹצֵץ וְנוֹתֵן דָּמִים. סָפֵק זֶה קָדַם, סָפֵק זֶה קָדַם, קוֹצֵץ וְאֵינוֹ נוֹתֵן דָּמִים:
A tree is distanced twenty-five cubits from a city, [an open place before a city enhancing its appearance.] And with a carob and a sycamore, fifty cubits, [their foliage being thick]. Abba Saul says: With every fruitless tree, [which detracts from the city's appearance], fifty cubits. If the city were first, he [the city owner] cuts it down and does not compensate (the owner of the tree); and if the tree were first, he cuts it down and compensates. If it were in doubt (which came first), he cuts it down and does not compensate. [For since it must be cut down no matter which came first, after it is cut down its owner is told: "Prove that it was there first and you will be paid."]
Jerusalem Talmud Peah
74This Mishnah is the continuation of the preceding one.: But for carob trees all that see one another75According to Maimonides, all the carob trees a man can see standing next to one of them. According to R. Abraham ben David, all the carob trees a man can see while standing on top of one of them. According to the second opinion, fences are never a problem for carob trees.. Rabban Gamliel76Rabban Gamliel of Jabneh, speaking of the family of Hillel. said, in my father’s house they used to give one peah for the olive trees they had in every direction77Four peot for all olive trees in all four main directions. and for all carobs that saw one another. Rebbi Eleazar ben Rebbi Ẓadoq said in the former’s name: also for all carob trees they had in the entire town.
