The holes at the bottom would let in air to keep the fire going, the top is the "chimney" and the hole in the front lets you insert a long match or other fire-starter so you don't burn your hand off lighting the thing.
Back in the "old" days citrus growers used to use things like that to generate heat on cold nights in their groves. Now they use fans and water.
