I started rereading from the beginning of island history. Starting with the wreck of the Norwich city. I read that. The Eric Bevington's journal. Then onto the New Zealand survey pages.
Somewhere in those pages. I read where someone had mentioned seeing two ruined shacks with tin roofs near the lagoon. Does anyone remember reading that? If so could you post the link. I have no idea what terms to search for to find that page again.
