^i^CTvhorsjunction?" The grounds upon which relief is asked, in substance are, that the ditch was not constructed in accordance with the plans and specifications, and that the board of supervisors fraudulently and negligently paid for more work than was actually done or was required to be done according to the specifications. The claim being the amount of excavation according to the specifications was only about two thousand cubic yards, while the board paid for upwards of five thousand yards.

The county surveyor made a report to the board of the number of cubic yards excavated, and the board after examining the ditch, determined it had been completed in accordance with the contract, and paid the contractor for the amount of earth excavated as shown by the report of the surveyor. Under such circumstances in the absence of fraud the action of the board cannot be reviewed in this proceeding. Patterson v. Baumer, 43 Iowa, 477.

There is not a particle of evidence tending to show fraud or collusion on the part of the board, unless the fact that the amount of excavation paid for exceeded that called for by the specifications is sufficient to establish such proposition. We do not think it is. It must be remembered the county surveyor reported the amount of excavation actually done, and there is no evidence showing he thereby perpretrated a fraud. It is not to be presumed the board had the requisite knowledge to *314enable them to determine the amount of excavation. They were not even guilty of negligence in relying on the report of the. county surveyor, much less of fraud.

This ditch was constructed .at the instance of the plaintiffs, and they knew they were bound to pay therefor, and yet they took no steps to inform themselves as to whether it had been properly constructed in accordance with the specifications until it was paid for by the county. The result of their present action if successful, would be to shift the burden from themselves upon all the tax payers of the county. We think the objection now made in the absence of fraud comes too late.

Affirmed.
