125 Eduyot 4/3-6

(3) Beit Shammai says: [That which was made] ownerless for [only] the poor is [considered] ownerless. Beit Hillel says: It is not [considered] ownerless until he also makes it ownerless for the rich, like in shemittah [the septennial "year of release" during which all produce is considered ownerless for everyone]. [If] all the sheaves of the field were just one kav [a measure], and one was of four kabin and it was forgotten, Beit Shammai says: It is not [considered] forgotten. And Beit Hillel says: It is [considered] forgotten.

(4) A sheaf that is close to a wall, or to a stack, or to the herd, or to vessels, and it was forgotten, Beit Shammai says: It is not [considered] forgotten. And Beit Hillel says: It is [considered] forgotten.

(5) A vineyard in its fourth year [the fruits of which must be brought to and consumed in Jerusalem], Beit Shammai says: [If one wishes to redeem its fruit for money], it is not [required to add] one-fifth [of its value, like it would be for second tithe], nor [is it required] to remove [the fruits of the vineyard before Passover, like it would be for other tithes in the fourth or seventh years of shemittah]. Beit Hillel says: It is [required to add] one-fifth [of its value] and [it is required] to remove [the fruits before Passover]. Beit Shammai says: The [law of] fallen grapes [still applies] to it [where the owner must leave any fallen grapes for the poor] and the [law of] gleanings [still applies] to it [where the owner may not pick the vines bare], and the poor may redeem [the grapes they pick] for themselves. And Beit Hillel says: All of it goes to the winepress [and no grapes need to be reserved for the poor].

(6) A barrel of pickled olives, Beit Shammai says: One need not poke holes in it [as it is assumed that the oil in the barrel is undesirable, which immunizes the olives from the ritual impurity to which wet food is susceptible]. And Beit Hillel says: He must poke holes in it [to actively demonstrate that the oil in the barrel is undesirable]. They both agree that if it was perforated and the dregs blocked up [the holes], that it is pure [and one need not worry about the olives contracting ritual impurity]. One who anointed with pure oil and became impure, and [with the oil on him] went down [to the ritual bath] and immersed, Beit Shammai says: Even if he is dripping [oil], he is [considered] pure. And Beit Hillel says: [He is considered pure only if the oil on him is just] enough to cover a small limb. If the oil was impure from the start, Beit Shammai says: [He is pure as long as the oil on him is just] enough to cover a small limb. And Beit Hillel says: [He is impure if there is enough oil] as a moist liquid [to moisten whatever is in direct contact with it]. Rabbi Yehudah says in the name of Beit Hillel: [It needs to] moisten [whatever is in direct contact with it] and moisten [another area else as well].
