One who buys two trees in the field of another has not acquired any land. R' Meir says: He has acquired land. [If] they grew, he may not trim [them]. Whatever grows from the trunk belongs to him; from the roots, to the owner of the land; and if they died the land is not his.  [If] he bought three, he has acquired land. [If] they grew, he may trim [them]; whatever grows from the trunk and the roots belongs to him, and if they died the land is his.

One who sells the head of a large animal has not sold the legs; [if] he sold the legs, he has not sold the head. [If] he sold the trachea, he has not sold the liver; [if] he sold the liver, he has not sold the trachea. However, in [the case of] a small animal, [if] he sold the head, he has sold the legs; [if] he sold the legs, he has not sold the head. [If] he sold the trachea, he has sold the liver; [if] he sold the liver, he has not sold the trachea.

There are four rules for dealing with sales: [If] he sold him superior wheat and it was found to be inferior, the buyer can retract. [If he sold him] inferior [wheat] and it was found to be superior, the seller can retract. [If he sold him] inferior [wheat] and it was found to be inferior, [or] superior [wheat] and it was found to be superior, neither can retract. [If he sold him] red [wheat] and it was found to be white, [or] white [wheat] and it was found to be red; [or he sold him] olive wood and it was found to be sycamore, [or] sycamore and it was found to be olive; [or he sold him] wine and it was found to be vinegar, [or] vinegar and it was found to be wine —- both of them can retract.

[If] one sold produce to another, [if] he drew [it] but did not measure [it], he has acquired [it]; [if] he measured but did not draw [it], he has not acquired [it]. If he is prudent, he rents its space.  One who buys flax from another does not ac-quire [it] until he moves it from place to place. If it was attached to the ground and he detached any amount, he has acquired [it].
