A person may establish three heaps to a beis seah [in] his field; more than this, he must make a hollow; [these are] the words of R’ Shimon. But the Sages forbid [this] unless he lowers [the dumpsite] three [handbreadths into the ground] or raises [it] three [above the ground]. A person may place his dung in a stockpile. R’ Meir forbids this unless he lowers [the dumpsite] three [handbreadths into the ground] or raises [it] three [above the ground]. [If] he had a small amount, he may add to it continually. R’ Elazar ben Azaryah forbids [this] unless he lowers [the dumpsite] three [handbreadths], or raises [it] three, or unless he puts [it] on a boulder.

. Someone penning [animals] in his field makes a corral of two beis seah, [and then] removes three sides and leaves the middle; this results in his having penned an area of four beis seah. Rabban Shimon ben Gamliel says: An area of eight beis seah. [If] his total field was an area of four beis seah, he must leave over part of it, because of the appearance of impropriety. He [then] removes [it] from the enclosure and puts [it] into this field in the manner of those who store dung.
