He traced an ebbing and a flowing mind,
Expression ever varying.
This ebbing and flowing mind with its ever-changing expression is the charm of early childhood. It is the charm of all genius as well. Turn to Shelley's "Skylark." The student of Child Psychology never found more images chasing one another through the mind. The fancies follow one another as rapidly as if Shelley had been only four years old. Frank's father would have been troubled at the lack of business-like grasp of the subject. What was the skylark like? It was
Like an unbodied joy whose race is just begun.
Then again, it was
Like a star of heaven
In the broad daylight.
It was
Like a poet hidden
In the light of thought.
