12．Dolphins are not fish，but warmblooded animals．They live in groups，and speak to each other in their own language．In this way they are like other animals，such as bees and birds．But dolphins are very different from almost all land  animals．Their brain is nearly the same size as our own，and they live a long time-at least twenty or thirty years．
Like some other animals，dolphins use sound to help them find their way around．They also make these sounds to talk to each other and to help them find food．We now know they do not use their ears to receive these sounds，but the lower part of the mouth，called the jaw．
Strangely，dolphins seem to like man，and for thousands of years there have been stories about the dolphin and its friendship with people．There is a story about sailors in the 19th century．In a dangerous part of the sea off the coast of New Zealand，they learnt to look for a dolphin called Jack．From 1871to 1903 Jack met every boat in the area and showed it the way．Then in 1903 a passenger on a boat called the Penguin shot and wounded（伤害）Jack．He recovered and for nine years more continued to guide all ships through the area-except for the Penguin．
Today，some people continue to kill dolphins，but many countries of the world now protect them and in these places it is against the law to kill them．

18．As a young boy，I sometimes traveled the country roads with my dad．He was a rural mail carrier，and on Saturdays he would ask me to go with him．Driving through the countryside was always an adventure：There were animals to see，people to visit，and chocolate cookies if you knew where to stop，and Dad did．
In the spring，Dad delivered boxes full of baby chickens，and when I was a boy it was such a fun to stick your finger through one of the holes of the boxes and let the baby birds peck on your fingers．
On Dad's final day of work，it took him well into the evening to complete his rounds because at least one member from each family was waiting at their mailbox to thank him for his friendship and his years of service．"Two hundred and nineteen mailboxes on my route．"he used to say，"and a story at every one．"One lady had no mailbox，so Dad took the mail in to her every day because she was nearly blind．Once inside，he read her mail and helped her pay her bills．
Mailboxes were sometimes used for things other than mail．One note left in a mailbox read．"Nat，take these eggs to Marian； she's baking a cake and doesn't have any eggs．"Mailboxes might be buried in the snow，or broken，or lying on the groom，but the mail was always delivered．On cold days Dad might find one of his customers waiting for him with a cup of hot chocolate．A young wrote letters but had no stamps，so she left a few buttons on the envelope in the mailbox； Dad paid for the stamps．One businessman used to leave large amounts of cash in his mailbox for Dad to take to the bank．Once，the amount came to 32，000．
A dozen years ago，when I traveled back to my hometown on the sad occasion of Dad's death，the mailboxes along the way reminded me of some of his stories．I thought I knew them all，but that wasn't the case．
As I drove home，I noticed two lamp poles，one on each side of the street．When my dad was around，those poles supported wooden boxes about four feet off the ground．One box was painted green and the other was red，and each had a long narrow hole at the top with white lettering：SANTA CLAUS，NORTH POLE．For years children had dropped letters to Santa through those holes．
I made a turn at the comer and drove past the post office and across the railroad tracks to our house．Mom and I were sitting at the kitchen table when I heard footsteps．There，at the door，stood Frank Townsend，Dad's postmaster and great friend for many years．So we all sat down at the table and began to tell stories．
At one point Frank looked at me with tears in his eyes．"What are we going to do about the letters this Christmas？"he asked．
"The letters？"
'I guess you never knew．"
"Knew what？"
"Remember，when you were a kid and you used to put your letters to Santa in those green and red boxes on Main Street？It was your dad who answered all those letters every year．"
I just sat there with tears in my eyes．It wasn't hard for me to imagine Dad sitting at the old table in our basement reading those letters and answering each one．I have since spoken with several of the people who received Christmas letters during their childhood，and they told me how amazed they were that Santa had known so much about their homes and families．
For me，just knowing that story about my father was the gift of a lifetime．
