{Shabbat 156a continues}
But that is only if one does it in an unusual manner.
How does one do it in an unusual manner? Hand by hand. To explain, little by little.

And from the fact that we answer according to the opinion of Rabbi Yossi beRabbi Yehuda, we may deduce from this that the halacha is like him.

Yet they are in accord that shatit {a drink prepared of flour and honey} may be stirred round on Shabbat, and Egyptian beer may be drunk {even though it is sometimes drunk for medicinal purposes}. And specifically if it is soft {a loose mass, like shatit}, but if it is thick {like dough}, no. And soft, also, they only said if he does it in an unusual manner.

How does one do it in an unusual manner?
Rav Yosef said: During the week the vinegar is [first] poured in and then the shatit, whereas on Shabbat the shatit is [first] poured in and then the vinegar.

Levi the son of Rav Huna bar Hiyya found {on Shabbat} the mixer of his father's household {whose job it was to mix fodder for cattle} mashing [up bran] and feeding the oxen - to explain, he was mashing up the coarse grain - Thereupon he rebuked him.
Then his father came and found him [there].
He {his father} said to him: Thus did your maternal grandfather, say in Rav's name - and who is he {the maternal grandfather}? - Rabbi Yirmiya bar Abba: One may mash [bran] but not force it [on the animal]; and if it [the animal] cannot take it [the fodder] up with its tongue one may feed it; provided, however, that it is done in an unusual manner.
How is it done in an unusual manner?
Rav Yemar bar Shelemia cited Abaye: [By stirring it] crosswise {instead of round and round}.
But he cannot mix it well [then]?
Rav Yehuda said: He shakes it into another vessel. {kli acher. our gemara omits acher, implying: he shakes up the vessel itself}
That is to say, he moves the spoon crossways, but does not stir with his hand, nor move the spoon round and round. And if it does not mix well, then he shakes it in another vessel.

It was recorded in Ze'iri's notebook: I said before Rebbi - and who is he {Rebbe}? - Rabbi Chanina: What about kneading {or mashing - bran}? and he told me: it is forbidden. What about emptying {from one vessel into another}? and he told me: It is permitted.

Rav Menashia said: : It is well [to place] one [measure of food] for one animal, and two for two; but [to place] three [measures] for two [animals] is forbidden.
Rav Yosef {our gemara: Yossi} said: even two kavs [may be set].
Ulla said: A kor and even two kor.

And the halacha is like Ulla.

{Shabbat 156b}
MISHNA:
GOURDS MAY BE CUT UP FOR CATTLE, AND A CARCASS FOR DOGS.
R. JUDAH SAID: IF IT WAS NOT NEBELAH FROM EREV SHABBAT IT IS FORBIDDEN, BECAUSE IT IS NOT MUKHAN

Gemara:
Ulla said: The halacha is like Rabbi Yehuda. And Rav also holds that the halacha is like Rabbi Yehuda. [This follows] from ship mattings, which Rav forbids and Shmuel permits.
And Shmuel said the halacha is like Rabbi Shimon {who permits many types of muktzeh}. And Ze'iri also holds that the halacha is like Rabbi Shimon. And Rabbi Yochanan also holds that the halacha is like Rabbi Shimon.

And the halacha is like Rabbi Shimon, for we say {Shabbat 157a}:

Rav Acha and Ravina differ therein: One maintains: In all [discussions on] about Shabbat, the halacha is as Rabbi Shimon, save in muktzeh on account of repulsiveness: and what is that? An old lamp. While the other maintains: In respect of muktzeh on account of repulsiveness too the halacha is as Rabbi Shimon, the exception being mukzeh on account of an interdict {issur}, and what is that? A lamp wherein a light had been lit on that self-same Shabbat. But in the case of muktzeh on account of monetary loss even Rabbi Shimon agrees, for we learnt {tnan}: All utensils may be handled on Shabbat, except a large saw and the pin of a plough.

And we have established that in any dispute between Rav Acha and Ravina, the halacha is like the words of the more lenient one.

MISHNA:
VOWS CAN BE ANNULLED {BY A HUSBAND} ON SHABBAT, AND ABSOLUTION MAY BE GRANTED {by a Sage or a court of three} FOR VOWS WHEN THESE ARE NECESSARY FOR SHABBAT.

A SKYLIGHT MAY BE CLOSED UP, AND A RAG MAY BE MEASURED, AND A MIKVEH MAY BE MEASURED.

IT ONCE HAPPENED IN THE DAYS OF R. ZADOK'S FATHER AND THE DAYS OF ABBA SAUL THE SON OF BOTNITH THAT THEY CLOSED UP THE WINDOW
