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, 10 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!
