IMPORT*ST—IF Tit UK.The good people of Keokuk, in thif State,have a mot! remarkable Corporation existing among them, known at the “Hydraulic Company.'’ Tbit concern came into existence some four years ego, and has for its object the improvement of the Kspids by means of a canal teven feet deep and one hundred and forty feet wide, witli sundry dams and locks. The nrst positive knowledge the public out of the suburbs of Keokuk had of the astounding phenomenon wa* at the Davenport Convention two years ago when every one there was iavored with a sight of it. It then went into w inter quarters never to be heard ofagain until the agitation of another Convention to improve the Rapids, when lo arid behold, the “Hydraulic Company” again comes forth to astonish the world.lt;i1(1Those rcnow ned brothers, the Messrs. Bangs, who are to improve the Des Moines river at such a fast rate, have, it seems, “signed, sealed, and deliverer!” a contract with the Secretary of said Company and sundry other potential individuals, te clear out the Rapids, blow the rocks sky high, create water power sufficient for one thousand pair of Burr stones, save all the trouble and expense of the Convention to he held here on the ”3d inst., ami do sundry other things too numerous to mention—so we learn by a printed circular recently received here, the postage of w hich was unpaid, price five cents. Truly the entiie freedom of “the Gate” should be voted to Banes Brothers without further delay.Col. AberttooXnever saw the Rapids) approvesof the “Hydraulics, it serins, and condemns the plan ot Major Lee, w ho spent tw o years on them and sounded every chain from Montrose to the foot, and whose report was so unanimously adopted as the only feasible plan of permanent improvement by the Davenpoit Convention toowears ago.We were in hopes that the people of Keoknk had sown their wild oats, and had determined 11 future to stick to their lighters, high water thougt it be, and leave to the folks above the Rapids tin settlement of this question. If their conduct i: any earnest of what those who intend coraini here as delegates from that renowned city an going to do, we advise them to stay at Lome am keep their humbugs there too.
