Sukkah סוכה

The tractate begins with which booth is fit: its height, its walls, its covering—and all of it for the sake of seven days a person lives outside a house. Then come the lulav and the etrog, how they are taken and what makes them unfit.

The fifth chapter describes the simchat beit ha-shoevah, the night festivity of the water-drawing at the close of the festival's first day: golden lamps in the Temple court whose light reached every courtyard in Jerusalem, the Levites on the fifteen steps, the elders dancing with torches. "Whoever has not seen that rejoicing has not seen rejoicing in his life."

Order: Moed. There is Gemara in both the Babylonian and the Jerusalem Talmud.
