Poked along low-spirited and on the watch-out.

[Aloyalfriend]

Hi,
I started out, after breakfast,_ feeling worried and shaky, and wondering where it was going to fall on me, and what it was going to be.There is ways to to keep off some kinds of bad luck, but this was not one of them kind; so I never tried tried to do anything,but just poked along low-spirited and on the watch-out.
This is some part of the novel * The Adventures of Huckleberry Finn*, chapter 4,what does the highlighted part mean?
