Aid for Sick and Wounded Illinois Soldiers — A State Sanitary Fair.

An important measure has been devised by the directors of the Illinois State Sanitary Commission for adding to the funds of the Commission, and enabling it to extend its benefits more liberally than ever to our soldiers in all parts of the army of the Union. The plan is to establish a Sanitary Department at the approaching State Agricultural Fair, to be held at Decatur on the 12th to the 17th days of September — in other words, to open a great Sanitary Fair. In this scheme the directors of the State Sanitary Commission have the approbation and are assured of the aid of the managers of the State Agricultural Society, and we now have before us a circular from the Secretary of the Commission explaining the matter, which we shall give to our readers in our next issue.

Notwithstanding the fact that the citizens of Illinois have already contributed many tens of thousands of dollars for the benefit of Illinois soldiers in the field, the means adopted to raise money for this purpose have been necessarily partial rather than general. Nevertheless, all parts of the State have furnished volunteers for our armies, and all are interested in the welfare of our troops. The plan of a Sanitary Department in connection with the State Fair, it is believed will reach more generally all classes of citizens than any yet devised. It will occur at the great gala-season of our agricultural population, when the labors of the tiller of other soil have been crowned with the fruits of the year. Such a Department can, and, no doubt, will be made a principal feature of the Fair, not only proving a success in itself, but contributing to the success of the enterprise with which it is connected. We understand it is the intention of the managers to spare no pains to render it a success, and they now appeal confidently to the people of the State to assist them in their noble effort. There is the more necessity for this measure, as no funds are provided from the Treasury of the State for the aid of our sick and wounded soldiers, as is the case in other States. All that can be done now, must be done directly by the people.

Illinois has a greater stake in this war than any other States. Of its more than one hundred and eighty thousand brave sons who have entered the field — many thousand in excess of all demands — we have a just right to be proud. Nor will Illinois be more niggardly in contributed to the welfare of its soldiers than it has been in furnishing those soldiers for the defense of the national honor and life. Let every man, woman and child in the State, then address themselves to the task of doing something to render the proposed Fair a success. Let all see to it that they shall be able to say they have done something to sustain and encourage our soldiers in the field.

We shall furnish more particular details of the plan of the proposed Fair in our next.
