the greatest respectability, a convention has been held at Chicago upon the same subject, a summary of whose views is contained in a memorial addressed to the President and Congress, and which I now have the honor to lay before you. That this interest is one which, ere long, will force its own way, I do not entertain a doubt, while it is submitted entirely to your wisdom as to what can be done now. Augmented interest is given to this subject by the actual commencement of work upon the Pacific Railroad, under auspices so favorable to rapid progress and completion. The enlarged navigation becomes a palpable need to the great road.

I transmit the second annual report of the Commissioner of the Department of Agriculture, asking your attention to the developments in that vital interest of the Nation.

When Congress assembled a year ago the war had already lasted nearly twenty months, and there had been many conflicts on both land and sea, with varying results. The rebellion had been pressed back into reduced limits; yet the tone of public feeling and opinion, at home and abroad, was not satisfactory. With other signs, the popular elections, then just past, indicated uneasiness among ourselves, while amid much that was cold and menacing the kindest words coming from Europe were uttered in accents of pity, that we were too blind to surrender a hopeless cause. Our commerce was suffering greatly by a few armed vessels built upon and furnished from foreign shores, and we were threatened with such additions from the same quarter as would sweep our trade from the sea and raise our blockade. We had failed to elicit from European Governments anything hopeful upon this subject. The preliminary emancipation proclamation, issued in September, was running its assigned period to the beginning of the new year. A month later the final proclamation came, including the announcementn of suitable condition would be received into the war service. The policy of emancipation and of employing black soldiers gave to the future a new aspect, about which hope, and fear, and doubt contended in uncertain conflict. According to our political system, as a matter of civil administration the General Government had no lawful power to effect emancipation in any State, and for a long time it had been hoped that the rebellion could be suppressed without resorting to it as a military measure. It was all the while deemed possible that the necessity for it might come, and that if it should the crisis of the contest would then be presented. It came, and, as was anticipated, it was followed by dark and doubtful days. Eleven months having now passed, we are permitted to take another review. The rebel borders are pressed still farther back, and by the complete opening of the Mississippi the country dominated by the rebellion is divided its, with no practical communication between them. Tennessee and Arkansas have been substantially cleared of insurgent control, and influential citizens in each, owners of slaves and advocates of slavery at the beginning of the rebellion, now declare openly for emancipation in their respective States. Of those States not included in the emancipation proclamation, Maryland and Missouri, neither of which three years ago would tolerate any restraint upon the extension of slavery into new territories, only dispute now as to the best mode of removing it within their own limits.

Of those who were slaves at the beginning of the rebellion full 100,000 are now in the U. S. military service, about one-half of which number actually bear arms in the ranks, thus giving
