“Killed suddenly by falling timbers.”

This newspaper article tells the story:

Wilmington Morning Star, 23 November 1909.

B.B. Tyler was working for P.L. Wood & Company (noted on the death certificate), who appears to have been the builder on-site at Contentnea Guano Company. Neither Tylor, a Maryland native whose regular occupation was ministry, nor P.L. Wood & Company are listed in the 1908 Wilson city directory.
