Pearl slides in.
The rebuilt sette afterwards. With very shallow settes, like this one, I put on a "roof" of fallen timber, bark and rotten wood, and then put the dirt back on top. If you do it any other way, the pipe is permanently blocked and the hole is never filled as (due to previous animal excavation) there is not longer enough dirt to do the job.
With deeper settes, I jamb the wood sideways into the hole, and then fill with dirt until flush with the ground. Vegetation mixed with the fill dirt helps keep the dirt stable, and may also speed revegetation around the sette.
