Gittin 60 - Shabbat July 15, 26 Tamuz

What is the order for who receives aliyot to the Torah after the first two (kohen and levi)? Is one allowed to read from a parchment that includes only one book of the Torah?  Is one permitted to write sections of the Torah for children to learn? Can the Oral Torah be written down? Other laws are discussed that were instituted because of darkhei shalom, which relate to where to put the food for the eruv and laws of precedence regarding filling up wells from an irrigation channel.
