¶1Petitions were filed with the auditors of Woodbury and Monona counties in August, 1908, praying for the establishment of a drainage district including lands in both counties. The boards of supervisors named Geo. L). Weintz, of Woodbury county, and E. M. Wooster, of Monona county, as commissioners, who appointed as engineer P. S. Holbrook, of Dos Moines, and in due time these commissioners and the engineer filed a report, accompanied by a profile, with the auditor of each county. As they recommended the improvement substantially as prayed, notice was given the landowners, and on April 8, 1909, the date designated therefor, all members of the respective boards of supervisors, three from Monona county and five from Woodbury county, met at Sioux City and organized, by electing Edington, from Monona county, chairman, and resolving that each member be entitled to one vote. They then unanimously adopted a resolution that the petition was sufficient in matter and form, that notice had been served as required, 'that the report of the commissioners and engineer had been duly filed, that “said drainage will be conducive to the public health, convenience, and welfare, and for the public benefit and utility, arid that the same is declared to be necessary,” and that, owing to the filing of claims for damages and objections, farther proceedings be continued till April 28, 1909. The mem*598bers convened as before at that time, and listened to evidence and arguments throughout the day and the day following, and on April 30th the commissioners and engineer, with J. M. Lewis ,as consulting engineer, were directed to reinvestigate especially as to location of the main ditch, and adjournment was taken to June 15th, when the commissioners and engineer filed an amended and substituted report, which Lewis acquiesced in and approved. Some important changes were made, but the main course of the ditch proposed continued east of the West fork of the Little Sioux river. The objectors were not opposed to the project of draining the district, but insisted that the ditch should be excavated part of the way about one and one-half miles west of that recommended. Adjournment was taken to June 23d, when, on motion, the amended and substituted report was adopted; two members from Woodbury county voting in the negative. Appraisers were appointed, notice ordered served on owners of land first included by the last report, and adjournment taken till August 10, 1909. Upon convening •then petitions for additional laterals were filed, and a general discussion for and against the establishment of the ditch followed. A motion to reconsider the plan previously adopted failed, four members from Woodbury county voting for it, and one member from Woodbury county with the three members from Monona county against; but they unanimously agreed to view the proposed district, in order to ascertain whether any lands should be added to or taken from the district, and, after doing so, again convened, when a discussion of the relative merits of the different plans was resumed, and the commissioners and engineer were directed to ascertain and report if other lands ought not to be included in the district. An adjournment was taken until September 21, 1909, when a resolution adopting the report of the commissioners and engineer as again amended was passed by a vote of seven to one, and notice *599to owners of land included by the last amendment ordered given. There was an adjournment until October 28th, when -the members again convened, and, after hearing claims for damages several days, adjourned to November 10th, and were in session on that day and the next hearing claims for damages, and on the 12th heard argument for and against the proposed improvement, at the close of which a resolution reciting everything essential in establishing the district and ordering the improvement was adopted by the vote of one member from Woodbury county and three members of Monona county for the resolution and four members of Woodbury county against.; This recital of the proceedings of the joint sessions of the boards of supervisors indicates with what care the members acted, both in informing themselves of the merits of the different routes proposed and in striving to settle upon that best adapted to drain the territory affected.

¶3The plan approved contemplates the intersection of the Skinner ditch about one and one-half miles below Holly Springs; but, according to the evidence, this ditch is of doubtful utility. By straightening out the river from the head of the proposed ditch, the carrying capacity will be multiplied by nearly four, and, according to the engineer, the velocity of the flow somewhat increased for at least four miles up stream. The expense of the plan rejected would be about $10,000 greater than that adopted, and there was so little difference in the relative merits of the two routes that the consulting engineer was influenced by this circumstance to approve of that adopted, although “all things being equal,” he would have preferred the west route. Another matter, should be mentioned. The east route (that adopted) passes through higher land, some of which has been tiled into the Monona-Woodbury ditch to the east.' Lowering the flow of the West Fork river a few inches will fully protect these lands, while along the west route the water gathers in large quantities when the river overflows its banks. Theoretically, the allowance of damages meets these objections, as well as the readjustment of tiling; but carrying a'large body of water over land out of its natural course would seem a continuing menace to the fields nearby. The answer is that the menace would be quite the same were the waters gathered in a ditch elsewhere. But the owners of lands nearby might not have equal ground of complaint. Everyone, of course, would prefer that such a ditch be located through the land of *602his neighbor rather than through his own. Moreover, it* must not be overlooked that the main purpose of the improvement is, not to relieve the district of ordinary surface water, but to relieve the West Eork river, by affording an adequate outlet for the waters which overflow its banks and now frequently flood the country below.
¶4It is apparent from the .above, and much more that might be said, that there are strong arguments for each plan and legitimate criticisms of each. Neither has much to commend it over the other; and, this being true, we are not ready to say that the commissioners and engineer, the consulting engineer, the boards of supervisors, and the district court are all mistaken in their approval of the plan adopted. All these, save the court, had been on the ground, and were in a better situation than we to pass on the merits of an engineering problem depending largely upon the topography of the country for its determination. After a careful examination of the record, we are not ready to say therefrom that the rojite is not as practicable, nor that it will not be as efficient, as would have been that proposed by the objectors. If there be doubt, it is as to the capacity of that portion of the ditch strengthening the river; for it would seem that the ditch below will carry an equal volume of water, and that this ditch might well bo enlarged enough to equal the carrying capacity of the river below where the ditch leaves it. No question as to the necessity of drainage is raised, and that the benefits resulting will exceed cost is put beyond cavil. We are not inclined to interfere with the conclusions of the district court.
