Dear reader! It rests with you and me, whether, in our two fields of action, similar things shall be or not. Let them be! We shall sit with lighter bosoms on the hearth, to see the ashes of our fires turn gray and cold.
But hearths seem not to have places for sitting on them, except maybe the narrow shelfs fit for cats and suchlike creatures. I would understand 'sit by the hearth' or 'sit close to the hearth', but why on?

As modern homes have made fireplaces more an aesthetic addition than a necessary one, the hearth has probably shrunken a bit to be less for sitting on, and more for staring at. The "hearth" can refer generally to areas around a fireplace. The "mantle" is a more specific term for the "narrow shelf for cats" above the fireplace.
