Read it through once

It struck me that Wemmick walked among the prisoners much as a gardener might walk among his plants. This was first put into my head by his seeing a shoot that had come up in the night, and saying, “What, Captain Tom? Are _you_ there? Ah, indeed!” and also, “Is that Black Bill behind the cistern? Why I didn’t look for you these two months; how do you find yourself?” Equally in his stopping at the bars and attending to anxious whisperers,—always singly,—Wemmick with his post-office in an immovable state, looked at them while in conference, as if he were taking particular notice of the advance they had made, since last observed, towards coming out in full blow at their trial.
