Evelyn Katchen, age 10, Brooklyn, N.Y.,   for her question:

Which is the biggest animal that ever lived?

Andy interviewed this fellow to get the facts for this story. The trip took our reporter to a deep spot in the north Atlantic Ocean. Mr. Monster was half a mile underwater, Andy waited in a small boat for him to come up for air. The big fellow arrived, puffing up a fountain of frothy vapor. He had been holding his breath for half an hour.

After a few smaller puffs, Mr. Monster was ready to answer questions Talking was difficult: The big fellows ears were plugged with six‑inch wads of wax, "When were you born", shouted Andy, who wanted an orderly interview. "On June 1, 1931,1t said the monster. "I'm not yet 26 years old." Obviously he was delighted to be interviewed and went on to give information without waiting for questions;

"I’m the biggest, bulkiest animal in the whole wide world," he said with a very, very broad smile. "I'm also the biggest animal that ever lived. I am over 100 feet long and I weigh over 150 tons. That makes me champ.

"Are you bigger than the old‑time dinosaurs?" said Andy, writing hard to keep up. "Pooh, none of those fellows was longer than 80 feet," scoffed the champ, "Then you must be much bigger than an elephant, the biggest land animal,' said Andy. "It would take 15 of those midgets to equal my weight," bragged the monsters "Why, I weighed 25 tons, as much as two full‑grown elephants, the day I was born. They’re no competition"

"What do you eat to build up such bulk," asked our reporter. "Plankton, plenty of plankton," was the quick reply, "The wonderful stuff just floats in the water," he went on to explain. "Its made of real midgets bitsy plants and bitsy animals ‑ maybe 200 to 2000 of them measure an inch, You might say I live on a sort of seafood salad."

"Don't you ever eat larger fish?" This question seemed to embarrass the monster, An oily tear slid from his eye. "Nothing larger than a shrimp," was the sad reply. "This mouth of mine is big enough to hold an elephant, But ,'see? I have a very small throat. "Also, and another oily tear slid down, "I have no teeth. "Wow" said our brave interviewer when he got back his breath. "Then what are all those things I just saw in your big mouth, Sir?" "Baleen," said the monster. "Not even bone. They are long horny strips that hang in curtains from the roof of my mouth. They act as strainers to sift out the plankton from seawater. Want to see them work?"

"No, no thanks," said Andy very quickly. "In fact I was so impressed that I forgot to ask the' most important question. What kind of animal are you, Sir?" "I'm a Blue Baleen Whale, of course," replied the champ, "Bye now, The plankton around here at this time of year is delicious and I must keep in training." With that, the big fellow took a deep breath and disappeared below, leaving Andy with a hoarse voice and a wet notebook.
