[The matters that the Mishnah forbids when they are wet,] this is not only if they are wet [due to themselves]. Rather, it is even if they were dry, and became wet.

Source: We learn from tufts. Are not tufts like something that was dry, and became wet?!

Inference (R. Yochanan bar Shila): In those matters in which one may do Hatmanah if they are dry, one may not fill the pot, lest some spill [and wet the insulating material] and it will heat [the pot].

(Mishnah): If a Tanur was heated with new Gefes [it is Tamei due to the liquid inside the Gefes], but with old Gefes, it is Tahor.

Question: What is new, and what is old?

Answer (R. Yosi bei R. Bun citing R. Yochanan): New is within 12 months (from when the olives were pressed). Old is after 12 months.

(Mishnah): One may do Hatmanah in garments, Peros and doves' feathers.

R. Yudah bar Pazi citing R. Yosi bar Chaninah says, this is when what rotted is not more [that what did not rot], but if there is more that rotted, it is forbidden.

(Mishnah): [Hatmanah is permitted in] fine chaff of flax and Nesores of carpeneters (sawdust);

Our Mishnah says "Nesores'' (what is sawed). Tana d'Veis Rebbi taught "Ne'ores'' (stubble). This teaches that they are the same.

(Mishnah): Hatmanah is permitted in hides, and one may move them. It is permitted in wool shearings, but one may not move them.

Question: How may one take the food? [He may not move the wool!]

Answer #1: He lifts the cover [of the pot with the wool on it], and the wool falls [to the side];

Answer #2 (R. Elazar ben Azaryah): He tilts the box [in which Hatmanah was done] and takes from the pot. If he would remove the pot, the pit (in which it was Tamun) might cave in, and it will be forbidden to return the pot;

Answer #3 (Chachamim): He takes [the pot] and returns it.

(Gemara - R. Yudah bar Pazi citing R. Yonason): [Our Mishnah permits moving skins;] it discusses by a Ba'al ha'Bayis, but not in an Apotiki (a storehouse for merchandise).

(Mishnah): [Hatmanah is permitted] in wool shearings, but one may not move them.

Inference (R. Yudah and R. Yochanan): [Our Mishnah forbids moving wool shearings;] it discusses in an Apotiki, but not by a Ba'al ha'Bayis.

(R. Yirmeyah citing Rav): We may spread mats [made to cover bricks] over bricks on Shabbos [lest rain fall on them, even though the bricks are Muktzah].

R. Shimon bar Rebbi: I did not hear this from my father. My sister told me in his name that an egg laid on Yom Tov (it is Muktzah, for it is Nolad), we may put a Kli next to it so it not roll, but one may not cover it with a Kli [for then it is blatantly for the sake of the Kli].

(Shmuel): One may cover it with a Kli.

(R. Mana): This is only if the Kli does not touch the egg itself.

(R. Hoshayah - Beraisa): A bee hive - one may spread a sheet over it when it is in the sun due to (to protect it from) the sun, or in the rain due to the rain.

Question: Is this like Rav [and unlike Shmuel, who does not permit resting a Kli on Muktzah]?

Answer: It is [even] like Shmuel. Here is above (the sheet is spread above the hive, and does not touch it) and here is below (Shmuel forbids resting a Kli on the Muktzah. We explained this like SEFER MASHBI'ACH.)

(R. Bisna citing R. Yosi bar Chaninah): Curtains used to cover a boat (PNEI MEIR, HA'GAON RAV C. KANIEVSKY, SHLITA), one may not move them.

Traps were set, and they were being scorched in the sun. They asked Rav whether they may move them.

Rav: Intend for them to put them under your heads, and you may move them (PNEI MOSHE; HA'GAON RAV C. KANIEVSKY, SHLITA - it is a Kli she'Melachto l'Isur, which is permitted if one needs to use it or its place).

(R. Ze'ira citing R. Yirmeyah): The heads of poles that he intended for them from Erev Shabbos, one may move them.

R. Yonah and R. Yosi went to Bar Ula's Beis Midrash. There was a gathering there, and there were heads of poles. They asked him whether they may move them.

Bar Ula: If you intended for them from Erev Shabbos it is permitted. If not, you may not move them.

(R. Chalifta bar Sha'ul): Tufts that he intended for them from Erev Shabbos - one may move them.

(R. Yosi ben Sha'ul): A stack of beams that one intended for them from Erev Shabbos, one may move them.

(R. Yosi citing R. Chaninah citing R. Yishmael b'Rebbi Yosi and R. Yakov bar Idi citing R. Chanina citing R. Yishmael bei Rebbi Yosi): My father's profession was with hides, and he used to tell us "tie the ends of of the skins [to prove that they are for sitting]'', and you may move them tomorrow.

(Chizkiyah): Even if he sewed a border on the edge [one may move them].
