They may surround [the camp] with pickets, provided that [the space] between one picket and the other is not three fists. They spoke of a caravan — [these are] the words of R’ Yehudah. But the Sages say: They spoke of a caravan only because it is common. Any partition not consisting of a warp and a weft is not [considered] a partition — [these are] the words of R’ Yose ben R’ Yehudah. But the Sages say: Either of the two. Four obligations were waived in a camp: They may bring wood from any-where; they are exempt from washing hands; from demai; and from making an eruv.

They may erect slats around wells, four double-posts which seem like eight — [these are] the words of R’ Yehudah. R’ Meir says: Eight which seem like twelve, four double-posts and four single ones. Their height [is] ten fists, their width six, and their thickness any size whatso-ever; and between them [is] the equivalent of two teams of three oxen each — [these are] the words of R’ Meir. R’ Yehudah says: Four each. Tied but not loose; one enters and one exits.

It is permitted to place [the slats] close to the well, provided that a cow has its head and most of its body within while drinking. It is permitted to place [the slats] at any distance, provided one increases the slats.

R’ Yehudah says: Until two beis-seah. They said to him: ‘They did not state two beisseah except in regard to a garden or karpeif. But if it was a fold, a corral, a backyard or a courtyard, even five korin, even ten korin, it is permissible. And it is permitted to place [the slats] at any distance, provided one adds slats.’’
