How much manure may they take out and make into dung-heaps? Three dung-heaps for every bet seah, [each consisting of] ten baskets [of foliage] of a letekh each. They may add to the number of baskets, but not to the number of heaps. Rabbi Shimon says: also to the number of heaps.

A man may deposit in his field three dung-heaps for every bet seah [and even] more, the words of Rabbi Shimon. The sages forbid unless he [deposits them] three [handbreadths] below or three handbreadths above. A man may pile up all the manure into one [large] store. Rabbi Meir forbids unless he [deposits them] three [handbreadths] below or three handbreadths above. If he had just a little, he may constantly add to it. Rabbi Elazar ben Azariah forbids unless he [deposits them] three [handbreadths] below or three handbreadths above or until he places them on a rock.

One who uses his field as a pen for cattle, he [first] makes an enclosure for every two bet se'ahs. He then uproots three sides, and leaves the middle side. It turns out that he has made a pen of four seahs. Rabban Shimon ben Gamaliel says: one of eight seahs. If his entire field is only four seahs in area, he must allow a portion of it to remain [unenclosed] for appearance's sake. And he may take the dung out from the enclosure, and spread across his field in the manner of those who fertilize their fields.

A man may not open a stone quarry within his field for the first time, unless there are in it three layers, each three [cubits long], three wide and three high, for a total of twenty-seven stones.

A wall that consists of ten stones, each a load for two men, may be removed, [if] the measurement of this wall is [at least] ten handbreadths high. Less than that he quarries it and he may lower it to within one handbreadth of the ground. When is this so? From his own field, but from that of another, he may remove whatever he wishes. When is this so? When he did not begin [to remove the stones] in the sixth year, but if he began in the sixth year, he may remove whatever he wishes.

Stones which the plow has turned up, or which had been covered and became uncovered, if there are among them at least two, [each] the load of two men, they may be removed. One who removes stones from his field, he removes the top layers, but he leave those touching the ground. And likewise a heap of pebbles, or a pile of stones; he may remove the top layers but must leave those touching the ground. If, however, there is beneath them rocky soil or stubble, they may be removed.

They may not build steps leading to ravines in the sixth year after the rains have stopped, for this would be improving the fields for the seventh year. But he may build in the seventh year itself, after the rains have stopped, for this would be a improving the fields for the eighth year. He may not block them [the steps] with earth, but he may make an embankment. Any stone which he can stick out his hand and pick up, may be removed.

Shoulder-stones may be removed from any place. And the contractor may bring them from anywhere. Which are shoulder-stones? Any one that cannot be picked up with one hand, the words of Rabbi Meir. But Rabbi Yose says: the name is to be taken literally; those that are carried on a man’s shoulder, either two or three at a time.

One who makes a fence between his own property and the public domain, he is allowed to dig down to rock level. What should he do with the soil? He piles it up in the public domain, and then restores it, the words of Rabbi Joshua. Rabbi Akiva says: just as no damage may be done to a public domain, so one may not repair it. Then what should he do with the soil? He heaps it up in his own field in the manner of those who bring out dung [for manure]. Similarly when one digs a cistern, a trench or a cave.
