Bycatch from my Snark hunt:
The, well, ambiguity of that “shadow”is known. Also there were some Freudian assumptions regarding what the salt could stand for. But so far I didn’t find any remarks on the impossibility of having a shadow being covered by white salt which isn’t covered by that shadow. To someone who learned physics that is a quite obvious question.

021 There was one who was famed for the number of things
022 He forgot when he entered the ship:
023 His umbrella, his watch, all his jewels and rings,
024 And the clothes he had bought for the trip.
025 He had forty-two boxes, all carefully packed,
026 With his name painted clearly on each:
027 But, since he omitted to mention the fact,
028 They were all left behind on the beach.
029 The loss of his clothes hardly mattered, because
030 He had seven coats on when he came,
031 With three pairs of boots–but the worst of it was,
032 He had wholly forgotten his name.

As for The Hunting of the Snark, I think that this is the most important finding of my Snark hunt.
