Describe Black beauty’s stable box at Squire Gorden’s Park. When did it first belong to?

From the text:

The first stall was a large square one, shut in behind with a wooden gate; the others were common stalls, good stalls, but not nearly so large; it had a low rack for hay and a low manger for corn; it was called a loose box, because the horse that was put into it was not tied up, but left loose, to do as he liked. It is a great thing to have a loose box.

Into this fine box the groom put me; it was clean, sweet, and airy. I never was in a better box than that, and the sides were not so high but that I could see all that went on through the iron rails that were at the top. He gave me some very nice oats, he patted me, spoke kindly, and then went away.

The box used to belong to Ginger.
