of Emerson's visit to the Carlyles in Scotland:

"The Carlyles were sitting alone at dinner on a Sunday afternoon at
the end of August when a Dumfries carriage drove to the door, and
there stepped out of it a young American then unknown to fame, but
whose influence in his own country equals that of Carlyle in ours, and
whose name stands connected with his wherever the English language is
spoken. Emerson, the younger of the two, had just broken his Unitarian
fetters, and was looking out around him like a young eagle longing for
light. He had read Carlyle's articles and had discerned with the
instinct of genius that here was a voice speaking real and fiery
convictions, and no longer echoes and conventionalisms. He had come to
Europe to study its social and spiritual phenomena; and to the young
Emerson as to the old Goethe, the most important of them appeared to
be Carlyle.... The acquaintance then begun to their mutual pleasure
ripened into a deep friendship, which has remained unclouded in spite
of wide divergences of opinion throughout their working lives."

Carlyle wrote to his mother after Emerson had left:

"Our third happiness was the arrival of a certain young unknown friend
named Emerson, from Boston, in the United States, who turned aside so
far from his British, French, and Italian travels to see me here! He
had an introduction from Mill and a Frenchman (Baron d'Eichthal's
nephew) whom John knew at Rome. Of course, we could do no other than
welcome him; the rather as he seemed to be one of the most lovable
creatures in himself we had ever looked on. He stayed till next day
with us, and talked and heard to his heart's content, and left us all
really sad to part with him."
