Clearly the redactors weren't worried about apparent contradictions! But Chapter 1 isn't quite sequential, since there Adam is created last of all the creatures on the sixth day, and in Chapter 2 the animals are created after him - apparently after the seventh day, although I guess the idea is this is a flashback. :-)

I just noticed a rather wonderful thing. In Chapter 1, God has been rather abstractly bringing things into being with words. In Chapter 2, He uses His hands - not just the familiar picture of making Adam from the clay, but he plants the garden of Eden. I have this lovely mental picture of God kneeling and working in the soil. Maybe with a little wheelbarrow by his side, humming "Morning Has Broken".
