Hotel
Having now completed our extensive factory which has enabled
us to meet the demands for our superior coffin, and being convinced that low process
will secure sales, and greatly accommodate those who are so unfortunate as to
need a coffin for their friends, we have reduced our process below what is now
paid for a mahogany coffin. We attend to conducting funerals in the country or
city with a strict regard to economy. Rumor to the contrary, the remains of Gen.
Z. Taylor never were placed in one of our coffins: nor has any single instance
ever occurred of one of them bursting from the fermentation of the body within.

Undertaker.
This was a rumor at the time here is the article that appeared in numerous papers about the exploding caskets. President Taylor has been exhumed numerous times HERE
