accompanying blueprint, and be established in height at 56 feet above dead low water, low water to be based on the records of the Cincinnati office, and that the harbor slopes be made every where 1 foot vertically to 3 feet horizontally, thus locating the dead low-water lines 168 feet distant from the harbor lines and parallel thereto, these arrangements to be effective on both banks of the river from Ashland to Hanging Rock, and that should these harbor lines be advanced farther toward the river either now or subsequently the advance must be not over 30 feet toward the river in any one place, and the party permitted to make such advance shall be required to first dredge from the river channel in front a volume of material equal to the volume to be filled in by the advance so as to keep the area of river cross section unchanged. After the harbor lines as laid down on the accompanying blueprint shall have been acted upon by the honorable Secretary of War, it will be necessary to transfer these lines as finally approved or ordered to the ground itself, and to place suitable monuments and benches by which the approved harbor lines may be readily recognized and conformed to by the riparian owners and other parties interested. At the same time this work is done it will probably be found that in some minor details the accompanying river survey map, made originally for other purposes, will need slight corrections as regards minor details, and the harbor lines will need slight adjustment thereto. This work will necessarily require a special survey and several months' time. It is therefore requested that after action by the War Department upon this report and blueprint, the latter be returned to this office and authority be given for the subsequent necessary fieldwork for the establishment of the lines in place. When such lines have been so established additional sheets and drawings in detail will be resubmitted, giving precise descriptions by which all points of lines may be accurately located and referred to, both in the field and in the office.
