Read it through once

My first impulse was to call up Herbert, and show him the two men going away. But reflecting, before I got into his room, which was at the back of the house and adjoined mine, that he and Startop had had a harder day than I, and were fatigued, I forbore. Going back to my window, I could see the two men moving over the marsh. In that light, however, I soon lost them, and, feeling very cold, lay down to think of the matter, and fell asleep again.
