Gov. Yates' Message.

The message of Gov. Yates is, without doubt, the most able and comprehensive, as it is the most elaborate and complete document of the kind that has ever exhausted from an Executive of this State. As a contribution to the current history of the State and of the country, it is invaluable; and it will long stand as a proud monument of an efficient vigorous and able Administration.

The local and domestic affairs of the State are discussed with a thoroughness which leaves little to be desired. These include within their range the interests of Agriculture, Manufactures and Education, all of which are recommended to the liberal encouragement of the Legislature. The rapid growth of the State in population and wealth are striking proofs of the prosperity which has marked the history of the State for years past. In the respects the State has already distanced many older members of the Union. The total value of real and personal property in the State is believed now to be not less than one thousand million of dollars. In population it has risen from the seventh State in the Union in 1850, to the fourth in 1860; and at the present rate of increase it is destined to become the second, if not the first, in 1880.

In railroads, Illinois is really the first, though nominally, the second State in the Union; having 3,000 miles of railroad in operation, intersecting the State in all directions. Ten years ago it had only ninety-five miles of road in operation. Within the same period the capital invested in the construction of railroads has increased from $1,446,507 to $104,944,561.

The Governor argues from the material resources of the State that it will overtake the older and most wealthy States, not merely in the value of its agricultural productions, but also in the value of its mineral products and its manufactures. We regard it as destined soon to become the great commercial center of the Union, as it is already the geographical center.

The importance of opening the Mississippi to the trade of the West is strongly urged upon the General Government. The prosecution of the geological survey of the State is earnestly urged as of the greatest importance in the development of its material resources. The State benevolent institutions are commended to the fostering care of the Legislature; and it is recommended that the necessary steps be taken to render available to the State the munificent grant by Congress of land for the establishment of Colleges of Agriculture and the Mechanic Arts. The question of banking and a uniform currency is discussed, and appropriate recommendations made in reference to them.

In spite of the war the material prosperity of the State has been comparatively but little affected, and the State credit is unimpaired. The receipts from the ordinary revenue of the State for two years past has been sufficient for all expenditures, and leaves a balance in the treasury of $374,697 19.

The portion of the message devoted to the discussion of matters connected with the war is necessarily large, and proves not merely the intimate acquaintance of the Governor with this subject, but the earnestness and care with which he has watched over the interests and welfare of our soldiers. Some important suggestions ere made for the purpose of increasing or continuing in efficiency measures already instituted for ministering to the comfort of sick and wounded soldiers; and also some action of the Legislature is proposed in reference to the payment of bounties by the State, and increase of the soldiers' pay by the General Government.

The closing part of the message is devoted to the consideration of the state of the country. This discussion is of the most thorough and exhaustive character. Gov. Yates, as might be expected from the earnest and unconditional support he has ever given to the Government gives to the emancipation proclamation of the President no doubtful or ambiguous indorsement. His argument on this point may be assailed, but we venture to say it will not be answered.

Upon the whole, the message is such a document as every Illinoisan may well be proud of. The Missouri Democrat, in closing a review of it, says:

Governor Yates' message is an able, thorough, and, in every respect, statesman like document. It exhibits conclusve evidence that he has studied deeply all the resources and the best interests of the State. He unfolds in a masterly manner the pre-eminent advantages that Illinois enjoys. Such a document is worth millions of dollars to the State, over the destinies of which he so holy and faithfully presides, in holding out to the emigrant the superior facilities for competence, and even wealth, it presents over most others. It will be read by the political economist, not only of this country but of Europe, with the greatest interest. Men of all parties will, we have reason to believe, accord to the Governor the merit of great ability in the production of this model state paper. He has treated of a variety of subjects, making his message voluminous; yet it is difficult to see in what respect it might have been advantageously curtailed.
