One who turned over his olives [to soften them] and then mourning befell him, or an accident [befell him], or [his] workers misled him, may place the first beam and leave it until after the festival. This is the opinion of R' Yehudah.  R' Yose says: He may pour [the olives into the press], complete [the process], and seal [the barrels] in his usual manner.

Similarly, one whose wine was in the vat and then mourning befell him, or an accident [befell him], or [his] workers misled him, may pour [the wine into barrels], complete [its processing], and seal [the barrels] in his usual manner. This is the opinion of R' Yose.  R' Yehudah says: He may cover [the barrels] with boards so that [the wine] does not sour.

A person may bring in his fruit because of thieves, and remove his flax from the soaking pond so that it does not become ruined, provided he does not plan his work for [Chol] HaMoed. In all these cases, if they planned their work for [Chol] HaMoed, it shall be forfeited.

We may not purchase homes, nor slaves, nor domestic animals, except for use during the festival, or [to provide] for the needs of the seller who [otherwise] has nothing to eat.  We may not move [objects] from one house to another, but one may move [objects from one house to another] within his courtyard.  We may not bring vessels from the artisan's shop; but if one fears for them, he may move them into a different courtyard.
