Under the limitation of armaments treaty a large saving in outlay and a considerable decrease in maintenance of the Navy has been accomplished. We should maintain the policy of constantly working toward the full treaty strength of the Navy. Careful investigation is being made in this department of the relative importance of aircraft, surface and submarine vessels, in order that we may not fail to take advantage of all modern improvements for our national defense. A special commission also is investigating the problem of petroleum oil for the Navy, considering the best policy to insure the future supply of fuel oil and prevent the threatened drainage of naval oil reserves. Legislative action is required to carry on experiments in oil shale reduction, as large deposits of this type have been set aside for the use of the Navy.
