Similarly, if a jar of oil [of Terumah] was upset, both R. Eliezer [T2 or T5] and R. Joshua [T2] agree that if he can save thereof at least a rebi`ith in cleanness he should save it; but if not, R. Eliezer [T2 or T5] says: let it flow away and be absorbed [in the ground] and let him not gather it up with his own hands.

R. Eliezer b. Jacob [T2 or T4] ruled: if four cubits of a drain were covered over in the public domain it is permitted to pour water into it on the Sabbath, but the Sages ruled: even where a roof or a courtyard was a hundred cubits in area, no water may be poured directly over the mouth of the drain, but it may be poured upon the roof from which the water flows into the drain. The courtyard and the exedra may be combined to make up the prescribed four cubits.
