04 Bava Kamma 3/3-6

(3) [If] one brings his straw [or thatch] into the public domain for fertilizer and another was damaged by them, he is responsible for the damage. And [furthermore], anyone who first [takes possession] of them is entitled [to the straw]. Rabbi Shimon ben Gamaliel says, anyone who destroys [objects] in the public domain, thereby causing damage is responsible to pay, and anyone who first [takes possession] of them is entitled. [If] one turns over dung in the public domain and another is damaged by it, he is responsible for the damage.

(4) [In the case of] two potters who were walking one behind the other, and the first tripped and fell, and the second tripped on the first, the first [potter] is liable for the damage to the second [potter].

(5) One came with his barrel and one came with his beam. [If] this one's jug were broken on this one's beam, [the beam's owner] is exempt, because this one has permission to walk and this one [also] has permission to walk. If the beam's owner was in front, and the barrel's owner was behind, [then] if the barrel broke on the beam, the beam's owner is exempt. [But] if the beam's owner stopped, he is liable. [But] if he said to the barrel's owner, "Stop," he is exempt. If the barrel's owner was in front, and the beam's owner was behind, [then] if the barrel broke on the beam, then he is liable. [But] if the barrel's owner stopped, he is exempt. [But] if he said to the beam's owner, "Stop," he is liable. So too [the case of] one who comes with his candle and one with his flax.

(6) [In the case where] two people were traveling in the public domain, one running and the other walking, or if both were running, and they damaged each other, both are exempt.
