Captain John Horr's old house, located on the island now known as Key Marco, has been partially taken over by the surrounding vegitation. Built in 1877 of tabby, a compound of seashells, sand and limestone, the house is a hollow shell that the inhabitants of Key Marco want to preserve. Anthropologist Matt Betz visited the site Monday to provide some pointers for how to keep the structure intact. He said it is the only tabby structure he knows of south of Tampa on Florida's west coast.
