what example of foreshadowing does twain use in this chapter?

The foreshadowing in Chapter 4 comes with Jim's telling Huck's fortune........

"Yo' ole father doan' know yit what he's a-gwyne to do. Sometimes he spec he'll go 'way, en den agin he spec he'll stay. De bes' way is to res' easy en let de ole man take his own way. Dey's two angels hoverin' roun' 'bout him. One uv 'em is white en shiny, en t'other one is black. De white one gits him to go right a little while, den de black one sail in en bust it all up. A body can't tell yit which one gwyne to fetch him at de las'. But you is all right. You gwyne to have considable trouble in yo' life, en considable joy. Sometimes you gwyne to git hurt, en sometimes you gwyne to git sick; but every time you's gwyne to git well agin. Dey's two gals flyin' 'bout you in yo' life. One uv 'em's light en t'other one is dark. One is rich en t'other is po'. You's gwyne to marry de po' one fust en de rich one by en by. You wants to keep 'way fum de water as much as you kin, en don't run no resk, 'kase it's down in de bills dat you's gwyne to git hung."
