Mr. Brown, son of a London stockbroker from Scotland, was a man several years older than Keats, born in 1786. He was a Russia merchant retired from business, of much culture and instinctive sympathy with genius, and he enjoyed assisting the efforts of young men of promise. He had produced the libretto of an opera, "Narensky," and he eventually published a book on the Sonnets of Shakespeare. From the date we have now reached, the summer of 1818, which was more than a year following their first introduction, Brown may be regarded as the most intimate of all Keats's friends, Dilke coming next to him. The pedestrian tour with Brown was the sequel of a family leave-taking at Liverpool. George Keats, finding in himself no vocation for trade, with its smug compliances and sleek assiduities (and John agreed with him in these views), had determined to emigrate to America, and rough it in a new settlement for a living, perhaps for fortune; and, as a preliminary step, he had married Miss Georgiana Augusta Wylie, a girl of sixteen, daughter of a deceased naval officer. The sonnet "Nymph of the downward smile" &c. was addressed to her. John Keats and Brown, therefore, accompanied George and his bride to Liverpool, and saw them off. They then started as pedestrians into the Lake country, the land of Burns, Belfast, and the Western Highlands. Before starting on the trip Keats had often been in such a state of health as to make it prudent that he should not hazard exposure to night air; but in his excursion he seems to have acted like a man of sound and rather hardy physique, walking from day to day about twenty miles, and sometimes more, and his various records of the trip have nothing of a morbid or invaliding tone. This was not, however, to last long; the Isle of Mull proved too much for him. On the 23rd of July, writing to his brother Tom, he describes the expedition thus: "The road through the island, or rather track, is the most dreary you can think of; between dreary mountains, over bog and rock and river, with our breeches tucked up and our stockings in hand.... We had a most wretched walk of thirty-seven miles across the island of Mull, and then we crossed to Iona." In another letter he says: "Walked up to my knees in bog; got a sore throat; gone to see Icolmkill and Staffa." From this time forward the mention of the sore throat occurs again and again; sometimes it is subsiding, or as good as gone; at other times it has returned, and causes more or less inconvenience. Brown wrote of it as "a violent cold and ulcerated throat." The latest reference to it comes in December 1819, only two months preceding the final and alarming break-down in the young poet's health. In Scotland, at any rate, amid the exposure and exertion of the walking tour, the sore throat was not to be staved off; so, having got as far as Inverness, Keats, under medical advice, reluctantly cut his journey short, parted from Brown, and went on board the smack from Cromarty.
