More on the altars outside and prior to the Temple - from Gilgal to Nov & Givon, and Shilo (when private altars weren't allowed). The Gemara explains that a verse in Deuteronomy that speaks of "menuchah" (rest) and "nachalah" (inheritance) should be applied to Shilo and Jerusalem, or perhaps the reverse. Also, investigating the claim that there were no grain-offerings at a private altar. The Gemara also pushes for implicit recognition that bird-offerings and grain-offerings were fundamentally different from larger animal sacrifice, which seem to have been more special.
