The Stepping-Stones

The struggling Rill insensibly is grown
Into a Brook of loud and stately march,
Crossed ever and anon by plank or arch;
And, for like use, lo! what might seem a zone
Chosen for ornament--stone matched with stone
In studied symmetry, with interspace
For the clear waters to pursue their race
Without restraint. How swiftly have they flown,
Succeeding--still succeeding! Here the Child
Puts, when the high-swoln Flood runs fierce and wild,
His budding courage to the proof; and here
Declining Manhood learns to note the sly
And sure encroachments of infirmity,
Thinking how fast time runs, life's end how near!
