A failed experiment

So, my first bread baking experiment was a dismal failure. In the picture, the bread looks OK--rustic and handmade. However, as soon as you pick it up, it's clear that something is very, very wrong. Each loaf is heavy like a brick; there are no air bubbles to be found. And I was expecting (hoping for?) a nice, light sandwich bread-type bread!

I'll consult wiser bakers before trying this again...
