Oversea Mail Service There are good reasons why all mail service from overseas is speedier than the service in the opposite direction, Ninth Service Command officials pointed out today. to-day. The matter of delayed delivery of mail addressed to persons overseas over-seas is explained many times a day by the Army's efficient postal post-al service.

Letters destined for overseas, therefore, usually must go through the directory service to locate the addressee. Their letters home are delivered to a fixed address. Mail is ,dispatched at regular intervals. However, on either side of an ocean it must wait for transporation and daily letters will accumulate as long as the mail must be held for a ship. Air mail too , must wait. If planes are available, the oldest air mail is shipped. When a fast surface vessel is about to make a journey, sufficient letters, including in-cluding delayed air mail letters, are carried to clear the backlog. As a consequence, letters may not arrive in sequence. Air mail dispatches dis-patches immediately following such surface shipments will reach the addressee ahead of older letters. Personnel aboard are being aa-vised aa-vised to encourage their correspondents corres-pondents at home to use V mail. V-mail ALWAYS moves by air, is faster and, above all, eliminates usage of valuable cargo space. Every effort is made to deliver mail to overseas hospitals speedily. speed-ily. However, evacuation to a hospital hos-pital means mail must be for. warded from an original organlz. ation. This may be complicated til the patient reacnes a perman. by another series of transfers un-ent un-ent hospital and can send his new address for direct communication. Mail from home, even a few lines a day, is the greatest morale builder in the world, keep those letters coming, and try to un. derstand the delay in receiving replies, is the advice of the Army postal service. It may take time, but where-ever where-ever the Army goes, the mail fol-lows.
