Wordsworth was the most affectionate of fathers, and allusions to his children occur frequently in his poetry. Dora--who was the delight of his later years--has been described at length in _The Triad_. Shorter and simpler, but more completely successful, is the picture of Catherine in the little poem which begins "Loving she is, and tractable, though wild," with its homely simile for childhood-- its own existence sufficient to fill it with gladness: As a faggot sparkles on the hearth Not less if unattended and alone Than when both young and old sit gathered round And take delight in its activity. The next notice of this beloved child is in the sonnet, "Surprised by joy, impatient as the wind," written when she had already been removed from his side. She died in 1812, and was closely followed by her brother Thomas. Wordsworth's grief for these children was profound, violent, and lasting, to an extent which those who imagine him as not only calm but passionless might have some difficulty in believing. "Referring once," says his friend Mr. Aubrey de Vere, "to two young children of his who had died about _forty years_ previously, he described the details of their illnesses with an exactness and an impetuosity of troubled excitement, such as might have been expected if the bereavement had taken place but a few weeks before. The lapse of time seemed to have left the sorrow submerged indeed, but still in all its first freshness. Yet I afterwards heard that at the time of the illness, at least in the case of one of the two children, it was impossible to rouse his attention to the danger. He chanced to be then under the immediate spell of one of those fits of poetic inspiration which descended on him like a cloud. Till the cloud had drifted, he could see nothing beyond." This anecdote illustrates the fact, which to those who knew Wordsworth well was sufficiently obvious, that the characteristic calm of his writings was the result of no coldness of temperament but of a deliberate philosophy. The pregnant force of his language in dealing with those dearest to him--his wife, his sister, his brother--is proof enough of this. The frequent allusions in his correspondence to the physical exhaustion brought on by the act of poetical composition indicate a frame which, though made robust by exercise and temperance, was by nature excitable rather than strong. And even in the direction in which we should least have expected it, there is reason to believe that there were capacities of feeling in him which never broke from his control. "Had I been a writer of love-poetry," he is reported to have said, "it would have been natural to me to write it with a degree of warmth which could hardly have been approved by my principles, and which might have been undesirable for the reader."
