Humbug's Grammar - Exercises

A light shone from the window of a hut, and swiftly they advanced towards it. Passing through the wall of mud and stone, they found a cheerful company assembled round a glowing fire. An old, old man and woman, with their children and their children's children, and another generation beyond that, all decked out gaily in their holiday attire. The old man, in a voice that seldom rose above the howling of the wind upon the barren waste, was singing them a Christmas song: it had been a very old song when he was a boy; and from time to time they all joined in the chorus. So surely as they raised their voices, the old man got quite blithe and loud; and so surely as they stopped, his vigor sank again.
But even here, two men who watched the light had made a fire, that through the loophole in the thick stone wall shed out a ray of brightness on the awful sea. Joining their horny hands over the rough table at which they sat, they wished each other Merry Christmas in their can of grog; and one of them: the elder, too, with his face all damaged and scarred with hard weather, as the figure-head of an old ship might be: struck up a sturdy song that was like a Gale in itself.
