February 23

1822  Congress authorized the Revenue Cutter Service to protect the natural environment by preventing “scoundrels” from cutting down live oak on Florida public lands.  The oak was used for naval construction.

1837  Congress called for an inspection of the coast from Chesapeake Bay to the Sabine River “with regard to the location of additional light-houses, beacons, and buoys.”  Captain Napoleon L. Coste, commanding the Revenue cutter Campbell, was dispatched.  He reported that the first addition to aids to navigation on this entire coast should be at Egmont Key, Tampa Bay.  A lighthouse was authorized immediately and built the next year.
