By mere omission, I presume, Congress has failed to provide chaplains for hospitals occupied by volunteers. This subject was brought to my notice, and I was induced to draw up the form of a letter, one copy of which, properly addressed, has been delivered to each of the persons, and at the dates respectively named and stated in a schedule, containing also the form of the letter marked A, and herewith transmitted. These gentlemen, I understand, entered upon the duties designated at the times respectively stated in the schedule, and have labored faithfully therein ever since. I therefore recommend that they be compensated at the same rate as chaplains in the Army. I further suggest that general provision be made for chaplains to serve at hospitals, as well as with regiments. The report of the Secretary of the Navy presents in detail the operations of that branch of the service, the activity and energy which have characterized its administration, and the results of measures to increase its efficiency and power. Such have been the additions, by construction and purchase, that it may almost be said a navy has been created and brought into service since our difficulties commenced. Besides blockading our extensive coast, squadrons larger than ever before assembled under our flag have been put afloat and performed deeds which have increased our naval renown. I would invite special attention to the recommendation of the Secretary for a more perfect organization of the Navy by introducing additional grades in the service. The present organization is defective and unsatisfactory, and the suggestions submitted by the Department will, it is believed, if adopted, obviate the difficulties alluded to, promote harmony, and increase the efficiency of the Navy. There are three vacancies on the bench of the Supreme Court--two by the decease of Justices Daniel and McLean and one by the resignation of Justice Campbell. I have so far forborne making nominations to fill these vacancies for reasons which I will now state. Two of the outgoing judges resided within the States now overrun by revolt, so that if successors were appointed in the same localities they could not now serve upon their circuits; and many of the most competent men there probably would not take the personal hazard of accepting to serve, even here, upon the Supreme bench. I have been unwilling to throw all the appointments northward, thus disabling myself from doing justice to the South on the return of peace; although I may remark that to transfer to the North one which has heretofore been in the South would not, with reference to territory and population, be unjust. During the long and brilliant judicial career of Judge McLean his circuit grew into an empire altogether too large for any one judge to give the courts therein more than a nominal attendance--rising in population from 1,470,018 in 1830 to 6,151,405 in 1860.
