The recent Message of Governor Yates is full of spirit, the right spirit, a warm and generous, a courageous and patriotic one. He glories in the great things he has to tell, but it is not 'as the fool boasteth,' but rather as the apostle, who, when he recounts only plain and manifest truths, says, 'Bear with me.' And truly, what wonders have been achieved by the 'men of men'! Since the war began, Illinois, though she has given one hundred and thirty-five thousand of her able-bodied men to the field, and though the closing of the Mississippi has produced incalculable loss, has sent away food enough to supply ten millions of people, and she has now remaining, of last year's produce, as much as can be shipped in a year. This enormous productiveness has given rise to the idea that Illinois is principally a grain-growing State, but she none the less possesses every requisite for commerce and manufactures. Not content even in war time with keeping up all her old sources of wealth, she has added to the list the production of sugar, tobacco, and even cotton, all of which have been found to flourish in nearly every portion of the State. The seventh State in point of population in 1850, she was the fourth in 1860, and in the production of coal she has made a similar advance. In railroads she is in reality the first, though nominally only the second; possessing three thousand miles, intersecting the State in all directions. Ten years ago the cost of all the railroad property within her bounds was about $1,500,000; in 1860 it was $104,944,561--an instance of progress unparalleled. But these are not the greatest things.
