Read it through once

With my heart thumping like a blacksmith at Joe’s broad shoulder, I looked all about for any sign of the convicts. I could see none, I could hear none. Mr. Wopsle had greatly alarmed me more than once, by his blowing and hard breathing; but I knew the sounds by this time, and could dissociate them from the object of pursuit. I got a dreadful start, when I thought I heard the file still going; but it was only a sheep-bell. The sheep stopped in their eating and looked timidly at us; and the cattle, their heads turned from the wind and sleet, stared angrily as if they held us responsible for both annoyances; but, except these things, and the shudder of the dying day in every blade of grass, there was no break in the bleak stillness of the marshes.
