One hundred and ninetyseven. I assume from my previous recommendations that so far as possible all U.S. mercantile ships are being sent in the regular convoys sailing from New York and Hampton Roads, and that other U.S. mercantile ships not sailing in these convoys are routed in co-operation with the regular shipping offices of the countries through the waters of which our shipping is bound(stop) If this assumption is correct steps should be taken to ensure that the Admiralty of the country furnishing the routing <orders> is furnished direct with all information regarding date of sailing, cargo, units, date of arrival, etc of the U.S. ships in the same manner and in the same codes as is now being done by the allied shipping representatives (stop) This will expedite and simplify the transmission of information to patrol ships (stop) It will be unnecessary and undesirable to furnish me list of these ships as I have arranged for the information to be forwarded to patrol forces direct from the Admiralties using their codes for the purpose
