The proper sequence of the panels is 5.1, 5.2, 5.3, 5.4, 5.7, 5.8, 5.5, 5.6. That is, the fourth tier should come between the second and the third tiers. Besides this, a careful look through the story reveals indications of extensive cutting and repasting, which is to be expected if a quarter of the story was dropped.
Judging from The Carl Barks Library - Set II, lots of tiers in the story look as if they're misaligned. Guessing where the cuts might be, one transition might be particularly strange: the dogs Donald is observing on page 2 appear to be on a very different place in panel 2.7 than in panel 3.1.
In panel 4.3, Donald refers to "the police department", "the fire
A sequence involving the police department may have been eleminated between panels 4.2 and 4.3. Another possibility could be that a scene with the police department took place between page 2 and page 3. If so, then either "the third dog from the end" in panel 2.7, or "the second dog from the bottom" in panels 3.1 and 3.2, may have been changed to make them look the same. And Donald's hook in panel 2.8 may have been something else, his landing-net for example.
The hook Donald is holding in panels 3.1, 3.2 and 3.4, looks like the
kind of hook as used in the radio-quiz ten-pager
The reason why Donald uses a hook instead of a landing-net, could be that the dogs are standing on top of each other. As Donald only wants to catch "the second dog from the bottom", a landing-net would be too unhandy. So, even if the dog in panel 2.7 is the same dog as the one in panels 3.1 and 3.2, there may at least have been an eliminated scene explaining why Donald decides to use a hook instead of a net. And an insertion of the hook in panel 2.8 would have smoothed over that cut. Would have, because this is all just guessing what might have happened. No cut art is known to have surfaced.
