8 TO ALL OBSERVERS
Many letters to observers acknowledging reports of marine data are returned to the Hydrographic Office on account of wrong or insufficient address.
It is realized that mariners change their addresses frequently and their mail in consequence is frequently delayed and sometimes lost; but the office is anxious to get letters of acknowledgment through to each observer, and to accomplish this it requests observers to indicate plainly in reports where acknowledgments should be sent.
Should any observer fail to receive an acknowledgment of information furnished this office, he may be sure that it is due to faulty address, as every report is acknowledged.

11 U. S. COAST GUARD STATIONS
All U. S. Coast Guard Stations on the Atlantic and Pacific coasts are equipped for signaling by the International Code, the Semaphore Code, the Occulting or Flashing-Light Code, and the International Morse Code (Wigwag). On the Atlantic coast those stations north of Cape Hatteras, with few exceptions, and on the Pacific coast those stations near lines of communication, are prepared to transmit messages of passing vessels either by telegraph or by telephone and telegraph combined.
