Lighthouse Service to the noncontiguous territory of Puerto Rico and adjacent American waters. (Weiss, p. 18).
1900	The tall-type can and nun buoys were introduced during this year for use in important positions, "the buoys being designed to stand much higher out of the water and thus furnish a mark easier to pick up, as well as much better resisting displacement by running ice." (Putnam, p. 218).

1903	(14 February) An Act of Congress (31 Stat. L., 826, 827) that created the Department of Commerce and Labor provided for the transfer of the Lighthouse Sen/ice from the Treasury Department to the newly created one, thus allowing the Secretary of Commerce and Labor to succeed to the authority vested in the Secretary of the Treasury under the existing legislation.
