Practice Speaking: Read Aloud
ID: #441
Long Tree Ring 2
Hence the sequence of the rings in a tree cross-section is like a message in Morse code formerly used for sending telegraph messages; dot-dot-dash-dot-dash in the Morse code, wide-wide-narrow-wide-narrow in the tree ring sequence. Actually the tree ring sequence is even more diagnostic and richer in information than the Morse code.
