<p>The Air Mail route between Washington and New York was discontinued on May 31. The reason for the discontinuance of this route is given in an announcement of the Department as follows: “This route has been kept in operation for a considerable length of time without serving any particular usefulness, either in connection with the mail service or in connection with experimental work, because it was felt that perhaps it would be possible to develop a long distance route between the principal New England cities and the large cities in the southeastern States, in which event the New York-Washington leg would be a very important part of the through route.</p>
