Synopsis:
Scrooge buys all the 1916 quarters in the world just to chuck them into the ocean. Except for one. It will be worth a fortune...

Comments:
Barks gives us some interesting possibilities about the whereabouts and look of mythical Atlantis. He lets an Atlantean teacher tell the ducks how their civilization began and prospered, and Barks even 'explains' how they came to survive and live under water.
One of Barks' great passions was archaeology (from an armchair's view) and he wrote a great number of stories in which the ducks travelled to far-away countries where they were confronted with the remains of old - and real - civilizations. There he was on much safer ground than in the Atlantis story.

Synopsis:
Worthless railroad shares are now going through the roof but Scrooge hid his near a spooky hotel in a ghost town...

Comments:
In about half of the Scrooge stories Barks lets the old miser remember a little something from his past that sets the stories in motion. In this one Scrooge remembers the whereabouts of his long-forgotten hidden shares. Incidentally, Barks even included a flashback of his own, because he drew the hotel in the story from memory; it was a hotel he once visited in Nevada.
In The Past and The Jobs (lower half) you will find additional examples of scattered information about Scrooge's life before the comic book stories took place (so to speak).

Synopsis:
Scrooge tries to hide his money in a far-away lake so The Beagle Boys can't find it. But it is not that easy...

Comments:
In some of the stories Barks had to come up with more concrete information about Scrooge's past in order to present the plots in an understandable way. In this one we are given several examples as to how Scrooge got as wealthy as he did. This also happened in FC0456 Back to the Klondike.
Other examples of flashbacks that are essential to the plots: In FC0238 Voodoo Hoodoo, FC0495 'Horseradish Treasure', and WDCS230 Black Wednesday Scrooge's past comes back to haunt him.

Synopsis:
A quarrel about putty escalates into a war between Donald and neighbour Jones.

Comments:
The two neighbours live in eternal strife and most of the time we are not aware what causes it and who is the instigator. But in this story we are given a little insight. It seems that this particular argument about putty started several years ago and has escalated since. This becomes apparent from scattered remarks.

Synopsis:
Donald and the nephews are hired to clean the huge stone head of Senator Snoggin on the side of Mount Mushmore. It's a bit of a nosy job...

Comments:
The story is sandwiched between a beginning and an end which take place in the present time. In this one Donald and the nephews take Daisy on a spin and they come across the monument on which they had previously worked. They tell Daisy about the job.
Barks used this authorial technique once in a while. The most famous examples come from WDCS146 'Omelet' in which Donald and the nephews - on yet another stroll in the countryside - disclose to Daisy how the small town of Omelet got its new name, and U$32 That's No Fable! in which Scrooge explains to the very astounded Grandma why he would not afford to buy the Fountain of Youth although it was for sale at a cheap price.
Grandma was also in the listener's role in U$GTD 'The Great Steamroller Race', where the main plot took place several years before.

Synopsis:
Donald longs to win a prize for his apples at the county fair and he is nursing them all summer long. But his neighbour is Gladstone!

Comments:
Here Barks embarks on a story that takes half a year! From the early spring when Donald decides to grow great apples and until the present time - which is in the autumn - when he has failed miserably.
A similar chronological tour is found in WDCS189 'The Backyard Garden' in which we follow Donald's futile attempts of beautifying his garden during a long summer.

Synopsis:
Following a traffic accident Donald and the nephews feel as they have travelled back a hundred years in time. They visit a Spanish ranchero and gold is found.

Comments:
The ducks fall asleep for six whole weeks due to the intake of some Indian herbs, which make them 'live' in ancient times.
This also happened in U$16 Back to Long Ago where both Scrooge and Donald are hypnotized a few hundred years back in time where they were Spanish conquistadors hiding a treasure chest.

Synopsis:
By accident, janitor Donald at The Duckburg Museum discovers that a square rock from Peru in fact is an egg. He is promptly sent out to get more...

Comments:
Many flashbacks are presented to us as dialogue only, and they often come from strangers whom the ducks meet on their way. In this story the old Indian remembers square eggs from his past, which is crucial to get the plot going. This also happened in FC0422 The Gilded Man where an old man gives Donald important information on how he can trace a rare stamp.
Other examples are FC0408 The Golden Helmet, U$25 The Flying Dutchman, and U$26 The Prize of Pizarro where we get necessary information from old maps, and in both FC0189 The Old Castle's Secret and U$21 The Money Well we hear titbits from Scrooge's past.
