You are now Washington's legitimate successor, and occupy a position of almost dangerous elevation; but if you can continue as heretofore to be yourself, simple, honest, and unpretending, you will enjoy through life the respect and love of friends, and the homage of millions of human beings who will award to you a large share for securing to them and their descendants a government of law and stability.

I repeat, you do General McPherson and myself too much honor. At Belmont you manifested your traits, neither of us being near; at Donelson also you illustrated your whole character. I was not near, and General McPherson in too subordinate a capacity to influence you.

Until you had won Donelson, I confess I was almost cowed by the terrible array of anarchical elements that presented themselves at every point; but that victory admitted the ray of light which I have followed ever since.

I believe you are as brave, patriotic, and just, as the great prototype Washington; as unselfish, kind-hearted, and honest, as a man should be; but the chief characteristic in your nature is the simple faith in success you have always manifested, which I can liken to nothing else than the faith a Christian has in his Saviour.

This faith gave you victory at Shiloh and Vicksburg. Also, when you have completed your best preparations, you go into battle without hesitation, as at Chattanooga--no doubts, no reserve; and I tell you that it was this that made us act with confidence. I knew wherever I was that you thought of me, and if I got in a tight place you would come--if alive.

My only points of doubt were as to your knowledge of grand strategy, and of books of science and history; but I confess your common-sense seems to have supplied all this.

Now as to the future. Do not stay in Washington. Halleck is better qualified than you are to stand the buffets of intrigue and policy. Come out West; take to yourself the whole Mississippi Valley; let us make it dead-sure, and I tell you the Atlantic slope and Pacific shores will follow its destiny as sure as the limbs of a tree live or die with the main trunk! We have done much; still much remains to be done. Time and time's influences are all with us; we could almost afford to sit still and let these influences work. Even in the seceded States your word now would go further than a President's proclamation, or an act of Congress.

For God's sake and for your country's sake, come out of Washington! I foretold to General Halleck, before he left Corinth, the inevitable result to him, and I now exhort you to come out West. Here lies the seat of the coming empire; and from the West, when our task is done, we will make short work of Charleston and Richmond, and the impoverished coast of the Atlantic. Your sincere friend,
