"Only in part; the Southern cause is weak through slavery, but strong in many other points. I think we have discussed this before." That we had done so did not prevent us from discussing it again. The Doctor seemed never to tire of presenting arguments for the complete abolition of slavery, while his even balance of mind allowed him to sympathize keenly with the political contention of the South. We had been talking for half an hour or so, when we heard some one approaching. The Doctor rose and admitted an officer. I saluted; then I was presented to Captain Auchmuty, of General Morell's staff. "I am afraid that my visit will not prove pleasant, Doctor," he said. "General Morell has learned that Mr. Berwick is here, and proposes to borrow him, if possible." The captain looked first at Dr. Khayme, and then at me; the Doctor looked at me; I looked at the ground. The captain continued, "Of course, General Morell understands that he is asking a favour rather than giving an order; but if he knows the circumstances, he believes you are ready to go anywhere you may be needed." "General Morell is very kind," said I; "may I know what work is required of me?" "Nothing is required; that is literally true." said Captain Auchmuty. "General Morell asks a favour; if you will be so good as to accompany me to his tent, you shall have the matter explained." The courtesy with which General Morell was treating me--for he could just as easily have sent for me by his orderly--made me think myself his debtor. "I will go with you, Captain," said I; "good-by, Doctor." "No," said the captain; "you will not be taken so suddenly. I promise that you may return in an hour." XVI BETWEEN THE LINES "Here stand, my lords; and send discoverers forth, To know the number of our enemies." --SHAKESPEARE. In General Morell's tent were two officers, afterward known to me as Generals Morell and Butterfield. It was not yet quite dark. The officer who had conducted me, presented me to General Morell. In the conversation which followed, General Butterfield seemed greatly interested, but took no part at all. General Morell spoke kindly to me. "I have sent for you," he said, "because I am told that you are faithful, and that you are prudent as well as accurate. We need information, and I hope you will get it for us." "I am willing to do my best, General," said I, "provided that my absence is explained to General Grover's satisfaction." "It is General Grover himself who recommends you," said he; "he is willing to let us profit by your services while his brigade is likely to remain inactive. I will show you his note." Captain Auchmuty handed me an open note; I read from General Grover the expression used by General Morell. "This is perfectly satisfactory, General," I said; "I will do my best for you." "No man can do more. Now, come here. Look at this map, which you will take with you if you wish."
