One who sells a donkey has sold the foal. [If] he sold a cow, he has not sold its calf. [If] he sold a dungheap, he has sold its manure. [If] he sold a pit, he has sold its water. [If] he sold a beehive, he has sold the bees. [If] he sold a dovecote, he has sold the doves. One who buys the production of a dovecote from another must allow the first brace to fly. [If he bought] the production of a beehive, he takes three swarms and [then] alternates. [If he bought] honeycombs, he must leave two combs. [If he bought] olive trees to cut, he must leave two branches.
