Gittin 60: Writing Down the Torah (Or Not)

The people who lived in the Galil wanted to know if they could read from the Torah for public reading from a chumash (a scroll of only one of the 5 books of the Torah). Turns out, it wasn't an easy question. Plus, can a scroll of one parsha be written for the sake of teaching children? The answer depends on whether you think the Torah was given as a while or piecemeal. Plus, Queen Helene's sheet of gold with the parsha of Sotah on it, for the kohen. But what about writing down the Oral Torah? Also, a dispute between Rav and Shmuel - how to irrigate which field when? Plus, a story of Abaye's need for irrigation, and issues of the priority of water, and battles over water distribution.
