Below on the floor at that corner was a [hollow] place [that measured] one amah by one amah, and [on top of this hollow there was] a marble tile with a ring fixed in it, that through it they would descend to the shis to clean it.  And there was a ramp to the south of the Altar, [which measured] thirty-two [amos] by a width of sixteen [amos]. And [the ramp] had an alcove built in to its west [side], for there they would place the unfit bird chatas [-offerings].
