At six o'clock he sat down to his library table, which was a plain ordinary piece of furniture, and read till dusk. During this period of dubious light, so friendly to thought, he rested in tranquil meditation on what he had been reading, provided the book were worth it; if not, he sketched his lecture for the next day, or some part of any book he might then be composing. During this state of repose he took his station winter and summer by the stove, looking through the window at the old tower of Lobenicht; not that he could be said properly to see it, but the tower rested upon his eye,--obscurely, or but half revealed to his consciousness. No words seemed forcible enough to express his sense of the gratification which he derived from this old tower, when seen under these circumstances of twilight and quiet reverie. The sequel, indeed, showed how important it was to his comfort; for at length some poplars in a neighboring garden shot up to such a height as to obscure the tower, upon which Kant became very uneasy and restless, and at length found himself positively unable to pursue his evening meditations. Fortunately, the proprietor of the garden was a very considerate and obliging person, who had, besides, a high regard for Kant; and, accordingly, upon a representation of the case being made to him, he gave orders that the poplars should be cropped. This was done, the old tower of Lobenicht was again unveiled, and Kant recovered his equanimity, and pursued his twilight meditations as before.
