No doubt it’s a world’s classic.
When not so long ago I reread the novel I have found out some new details which had slipped off my attention when I was a child. Here are a pair of “goofs”, or rather may be author's mistakes, which I have noticed in the story:
1. Billy Bones’s money had been exhausted but he keeps on staying on credit in the "Admiral Benbow" inn. However, after he had had a stroke he offers Jim a golden guinea for rum., and after his death Jim finds out at Billy Bones’s sea chest a heap of money.
2. Why Ben Gann has not buried Allardyce, and let his remains lie in that position in which it was put by Flint? Besides, during his three yeas maroon on the island Ben often, I think, had to go by that place where the dead and decaying body was laying, but mysteriously enough it did not occur to him to give the remains of his ship companion to the earth.
