Remove as much excess moisture from the wood as possible. A rag, t-shirt, towel or newspapers could all be effective in removing moisture by wrapping the wood in it. The wood will still be wet, but it will be easier to ignite.
Stack the wet logs so that there are air pockets between the pieces of wood. You don't want to stack the wood so that no air can flow through the pile.
Add tinder to the gaps in the log pile. Tinder can be any dry material, such as newspaper, dry leaves and grasses, wax or lint. Light the tinder to get the fire started. The fire will spread along the tinder into the spaces around the wood logs.
Mix in kindling to keep the fire burning while the moisture on the wood evaporates and the wood itself ignites. Kindling is smaller sticks, dead bark and other dry wood pieces that interact with the tinder to keep the fire going.
Add additional pieces of firewood as the fire grows until the fire is the size you want.
