Question: How could one support a pot with a door!?

Answer: It must be amended to mean that a door may, similarly, not be supported by a block of wood.

The Beraisa teaches that R. Shimon permits using a block of wood for these purposes.

Question: Does R. Elazar permit here in accordance with his father's opinion (that the stick is not Muktzah)?

Answer: Muktzah need not have been a factor with the stick, even for the Tana Kama whose prohibition may owe to its looking as if he is taking his animal to market to sell.

(R. Nachman): One may not use a spit-shaped Chizra.

(R. Sheshes): It is permitted.

Their Machlokes applies to a stick which is fit for (burning) use since it is dry, but not if it is damp.

R. Nachman assumes wood to be forbidden, and permitted only for firewood;

R. Sheshes that the permission to use the wood is unrestricted (no Muktzah).

Alternately, their Machlokes applies only if it is damp.

R. Nachman prohibits since it is not fit for use.

R. Sheshes permits since it could still be added to a large fire.

The Halachah (according to those who maintain Muktzah - Rashi) rules that a dry Chizra is permitted, but a wet one is not.

(Rava): One may not use an undesignated poker on Yom Tov.

Also, a designated poker may not be burned as kindling if it broke.

Question: But Rava permitted handling the innards of the bird (which R. Yehudah would presumably forbid since whatever is prepared for a person, is not fit for an animal) thus indicating that he does not hold of Muktzah in accordance with R. Yehudah!?

Answer: Even R. Yehudah would permit handling those innards since he intends, even before Yom Tov, to cast them to the cat (since they rot).

(R. Eliezer): One may take a splinter of wood (from "before him" but meaning from the Chatzer- Rashi) to pick one's teeth.

One may also collect splinters of wood scattered in the Chatzer, as they are Muchan, despite the effort entailed in gathering them.

(Rabanan): One may collect only splinters which are before him (not out in the Chatzer) and may then only use them for kindling, not as a toothpick.

One may not produce a fire in any manner on Yom Tov, nor may one heat roof-tiles to fry thereupon.

(R. Yehudah): Animal food may be used freely (no Tikun Kli).

Question (R. Kehana): But the Beraisa rules that one would be Chayav for fashioning a Kli from Besamim, presumably even from those which are fit for animals!?

(Beraisa): One may move Besamim for its fragrance and one may roll it in one's hand in order to bring out its smell.

One may not, however, break them to bring out their fragrance, lest he come to break them to fashion a toothpick (an Isur d'Oraisa).

Answer (R. Yehudah): The Beraisa is prohibiting hard wood, which is not fit for animal food.

Question: How then are they able to be rolled!?

Answer: The Beraisa must be amended to permit soft wood entirely (even to break a toothpick therefrom) and to prohibit hard wood, as above.

Question: One Beraisa permits breaking the Besamim for their fragrance and one forbids it (lest he fashion a toothpick therefrom)!?

Answer (R. Zeira citing R. Chisda): Soft wood is permitted and hard wood (not fit for fodder) is not.

Question (R. Acha b. Yaakov): But, based on the Mishnah which permits breaking open a barrel haphazardly (without intending to fashion a Kli) to obtain its contents, it should be permitted to break the Besamim for its fragrance (and we do not restrict him lest he fashion a Kli with intent)!?

Further Question: It was reported that R. Yehudah did so himself!?

Answer (for the second question): R. Eliezer (who holds in the cited Beraisa that breaking a splinter off a large piece of wood involves a d'Oraisa) prohibits, while R. Yehudah rules like the Rabanan (who hold, in the cited Beraisa, that such splintering is not Tikun Kli d'Oraisa).

Question: But the Beraisa teaches that R. Eliezer permits breaking open a vessel (provided that one does not intend to make a Kli)!?

Answer (to this and to the first question above) [R. Ashi]: That Beraisa is speaking of Mosteki, a broken barrel whose pieces are stuck together with resin.

(Rabanan): One may not gather the wood and pile it into a heap.

(R. Shimon): One may even make a heap.

Question: What is the basis for their argument?

Answer: Whether it appears as though he is collecting for future, post-Yom Tov use (Rabanan) or whether it will be assumed that his cooking requires it (R. Shimon).
