delivered the opinion of the court:
This is an appeal from a judgment of confirmation entered in the county court of Cook county April 20, 1898, confirming an assessment levied for the purpose of defraying the expenses of paving Bonney avenue, from Ogden avenue to Douglas Park boulevard. The objections to the confirmation were filed by Charles D. Lusk and Henry H. Gag"e, and among others was the following: “That the ordinance providing for the making of said improvement does not specify the nature, character, locality and description of the proposed improvement.” Other objections were filed, but in the view we take of the case it will only be necessary to consider this one.
*208Section 1 of the ordinance provides that the roadway of Bonney avenue, thirty feet in width, from the north line of Ogden avenue to the south line of Douglas Park boulevard, together with wings of all intersecting streets and alleys between the lines of said Ogden avenue projected across said intersecting streets and' alleys, be improved as follows: “Curb-stones shall be set on each side of the roadway of said Bonney avenue between the roadway lines of all intersecting streets and alleys, with returns at the wings thereof to the lines of said Bonney avenue projected, the face of which curb upon Bonney avenue shall be fifteen feet from the center of the roadway. Said curb-stones to be of the best quality of limestone, to be not less than four (4) feet long, three (3) feet deep and five (5) inches in thickness, with the upper outside corner rounded to a radius of three (3) inches, each stone to have a straight base the whole length, and to be firmly bedded upon fiat stones, each stone to be machine dressed and'set at the established grade of said Bonney avenue between the points named.”
•It will be observed that the flat stones upon which the curb-stones are to be bedded are not described in the ordinance, and upon this ground it is claimed that the ordinance fails to specify sufficiently the nature, character and description of the improvement. This court has held in a number of cases that an ordinance is invalid which fails to describe the nature, character and locality of the improvement. In Otis v. City of Chicago, 161 Ill. 199, an objection like the one interposed here was made to an ordinance for the erection of lamp-posts, and in deciding the question it was said (p. 200): “An ordinance for a local improvement to be paid for by special assessment must specify the nature, character, locality and description of the improvement. The provision of the statute to this effect is mandatory. Without such specification in the ordinance the commissioners could not make an intelligent estimate of the cost of the improvement. An ordinance which does *209not specify the nature, character, locality and description of the improvement is without authority of law, and therefore invalid. (City of Kankakee v. Potter, 119 Ill. 324; Levy v. City of Chicago, 113 id. 650; City of Sterling v. Galt, 117 id. 11.) It is evident that the present ordinance does not meet the requirement of the statute. It does not state whether the lamp-posts are to be of wood or iron, or for light with oil or gas or electricity.” In Cass v. People, 166 Ill. 126, a similar question was raised and the ordinance held invalid. It is there said (p. 127): “The ordinance here is of a precisely similar character,” (referring to the ordi-( nance in the Otis case, supra.) “It directs that a water service-pipe be laid from each of the lots, but does not specify whether these pipes are to be of wood or iron or tile, nor in any way indicate their size or dimensions. It is evident that no intelligent estimate can be made of their cost from the description in the ordinance.”
It is not mentioned in the ordinance here what kind of stones the flat stones shall be upon which the curbstones are to be bedded. Whether they are to be granite, sandstone, limestone of of some other quality is not disclosed by the ordinance, nor is there any specification of the size or shape, except that they are to be flat and machine dressed. No intelligent estimate could be made by the commissioners of .the cost of the stones unless the length, width, thickness and kind or quality were disclosed by the ordinance. As to the curb-stones, the ordinance provides that they shall be of the best quality of limestone, to be not less than four feet long, three feet deep and five inches in thickness, but as to the flat stones nothing is said in regard to their nature or character.
We think the ordinance is invalid, and the court erred in confirming the assessment. The judgment of confirmation as to the property of appellants will be reversed and the cause will be remanded.
