One who wishes to trim the leaves of vegetables to lighten his burden may not discard [the leaves] until he tithes [them]. One who purchases vegetables in the market and decides to return [them] may not return [them] until he tithes [them], since [the transaction] is lacking nothing but counting. [If] one was standing and purchasing [a load of vegetables], and saw another load better than [the first], it is permitted to return [the first load], since he did not draw [it].

[If] one finds fruit on the road and picks it up to eat, and then decides to place [it] in a sheltered spot [instead], he may not place [it] in a sheltered spot until he tithes [it]. But if he initially picked it up so that it not be destroyed, he is exempt [from tithing it]. Whatever a person is not permitted to sell [in a state of] demai, he may not send to his friend [in a state of] demai. R’ Yose permits [sending] definitely [untithed produce], provided that he informs him.

[If] one takes wheat to a Cuthean miller or to a miller who is an am haaretz, it retains its [original] status with respect to tithes and sheviis; to a heathen miller, [it is] demai. [If] one deposits his fruit with a Cuthean or with an am haaretz, it retains its [orig-inal] status with respect to tithes and sheviis; with a heathen, it's [status] is like [the heathen's] fruit. R’ Shimon says: it is demai.

One who gives [food] to the proprietress of an inn must tithe that which he gives her, and that which he takes back from her because she is suspected of exchanging [the food]. R’ Yose said: We are not responsible for connivers, he tithes only that which he takes back from her.
