Have been meaning to add to this for some time....Quoting (with permission) from a PM:

A sideboard was a specialized piece of furniture that people kept for the start of a hunt. It would be carried outside and piled high with food for the riders to eat from while on horseback. Sometimes they remained on a porch rather than being carried all the way into and out of the house.

It had long skinny legs which would be minimally affected by the urine and horse manure dropped helter skelter by the mounts.

Apparently it was also called a "hunt board."

Let us go in peace to love and serve the board.
