Gayle,
We've done a lot of pigs/hogs with the underground method, not my favorite way because it basically steams the meat as opposed to hickory smoking it. But, here's how we did it.
Dig a hole the appropriate size, then start a fire in the pit, a big one. Oak or hickory are the best fuel. Burn wood until you have a nice bed of glowing coals, about 12" to 18" deep. Wrap the pig in heavy brown paper or banana leaves if you can find them and tie with wire. Hose down the paper wrapped package in water then wrap with a piece of fencing (not the painted kind of fencing) to hold the whole deal together. You can also use chicken wire. Lay a piece of corrugated metal on the coals followed by the pig. If you like additional protection on your pig, we have laid water soaked burlap over the pig, then the dirt.
Some people lay a piece of pipe of 4" vent piping vertically down to the coals prior to the dirt part so the fire can breath.
So, a foot or two for the fire, a foot for the pig and a foot for the top dirt layer. Check the pig with a thermometer after 4 hours (dig a little hole) to see how quickly he's progressing, then time accordingly.
When it's done you'll have a mess of fall off the bone steamed pork.
Good luck.
