But besides the possession of all these books, and of this wonderful window, Dr. Kinkel was yet more fortunate in his domestic relations. He was married to an amiable, highly educated, and accomplished lady, who endeavored, by all the means in her power, to assist his labors, and render them less onerous by her own exertions. She was a very fine musician, and a superior piano-forte player--one of the favorite pupils of Moscheles, and afterward, we believe, of Mendelssohn. She divided her time equally between assisting her husband, educating their child, and giving private lessons in music; and because this accomplished hard working couple did not find their energies quite worn out by toiling for thirteen hours a day, they gave a private concert at the castle once a month, at which a whole opera of Mozart or Weber was often gone through--both the instrumental and vocal parts being by amateurs, or pupils of Madam Kinkel. So, once again, we say, notwithstanding all these labors, Dr. Kinkel's life in the Castle of Popplesdorf, was that of a fortunate and happy man. At this period he was about two-and-thirty years of age. He could not have been more; probably he was less. PICTURE THE THIRD. It is the year 1848, and the Continental Revolutions are shaking all the foreign thrones. Every body, not directly or indirectly in the pay of a court, feels that the lot of the people should be ameliorated. The populations of all nations have borne enormous burdens, with extraordinary patience, for a very long time--say a thousand years--and, at last, they have no more patience left. But what is all this to abstract thought, to learning and science, to poetic raptures, and picturesque ease? It has hitherto been regarded as too grossly material, or of too coarse and common a practicality for the great majority of those whose lives were passed in abstract studies and refinements. Ay--but this must not continue. The world has come to a pass at which _every_ soul must awake, and should be "up and doing." Dr. Gottfried Kinkel, now, besides his other honors and emoluments, and private earnings, is installed as a salaried professor in the University of Bonn. It can not be but such a man must awake, and take an interest in these continental revolutions which are boiling up all round him. Still, it is not likely he will step into the vortex or approach it. His worldly position is strong against it--all his interests are against it; moreover, he has a wife, and, besides he has now three children.
