110. Information from district officers.-The division engineer is authorized to call upon any district officer in his division for such data, reports, and charts belonging to the files of the office, and for such reasonable information or service as may be necessary for the consideration of matters relating to works of civil improvement and defense in his division, bearing in mind to avoid, as far as possible, the unnecessary duplication of records. To this end, it is believed that many papers can be profitably borrowed temporarily from the district officers, to be returned after the subject has had full consideration. (G. O. 9, C. of E., 1901.) 111. Office methods, etc.-The division engineer will exercise a proper supervision over the organization of the office force and office methods in the districts in his division, and will, from time to time, make such recommendations for changes and modifications as may seem desirable. (G. O. 9, C. of E., 1901.) 112. Forwarding papers.-No papers will be forwarded to the Chief of Engineers without a definite expression of opinion on the part of the division engineer. The division engineer will especially scrutinize all estimates of cost, satisfying himself as to the correctness of quantities and prices. In his inspections he will ascertain whether quantities and prices vary from the express terms of a contract or from the authority granted by the Chief of Engineers. The following papers will be forwarded through the division engineer: Requests for authorities under Circular 18, Office of the Chief of Engineers, 1904, §§ 414-419, 421-424, 501-505; leaves of absence; projects and other papers relating to engineering features of works; specifications, proposals, and abstracts of bids relating to formal contracts. (G. O. 9, C. of E., 1901, modified to date.) 113. Office force of division engineer.-In the performance of the duties required of him the division engineer will be allowed such office force as the Chief of Engineers may authorize, to be paid pro rata from the appropriations for the works in his division, but the Chief of Engineers desires that the office force and records be reduced to the minimum compatible with the proper performance of the duties above outlined. (G. O. 9, C. of E., 1901.) 114. Mileage.-Mileage due to the division engineer as provided for by law, for travel in connection with works of river and harbor improvement or other nonmilitary works, will be paid by the district officers from the proper appropriations. For travel on duty connected with fortifications, or on any other military duty, the mileage will be paid by the Pay Department. (G. O. 9, 1901, and Cir. 23, 1905, C. of E.) 115. When district officers are above the rank of major.— The regulations and orders defining the duties of division engineers are not intended to require that official papers (except projects) emanating from engineering districts in the charge of officers above the rank of major shall pass through the hands of division engineers, but each division engineer will inspect the principal works of all engineering districts within the geographical limits of his division at least once a year, and at such other times as in his opinion the interests of the service demand, or as may be directed by the Chief of Engineers, and upon the conclusion of each inspection will submit to the Chief of Engineers a report thereof, in accordance with the provisions of General Orders, No. 9, Headquarters Corps of Engineers, August 28, 1901 (see §108). Except projects, all matters relating to the administration of a district under the command of an officer above the rank of major will be the subject of direct communication between the district officer and the Chief of Engineers; a copy of all annual and monthly reports for the district will, however, be filed with the division engineer for his information in connection with his inspection duties. (G. O. 10, C. of E., 1903.) 116. Citations and cross references: (a) As to the assignment of division engineers, see E. R. 17. (b) Copies of reports of completed batteries, etc., to be furnished to the division engineer. (Cir. 17, C. of E., 1905,—§ 58.) CHAPTER V. FORTIFICATIONS. ALTERATIONS AND ADDITIONAL STRUCTURES. 117. The attention of all officers of the Corps of Engineers is called to A. R. 1534, with a view to its enforcement as far as possible. (Cir. 15, C. of E., 1896. ) NUMBERING EMPLACEMENTS. 118. At all posts with fixed batteries the position of every gun, mounted or to be mounted, will have its number, which will be placed on the gun when in position. Guns and mortars arranged in line will be numbered from right to left in separate series for each battery. The two pits of each mortar battery will be lettered from right to left or from rear to front A and B. The mortars in each pit will be numbered as follows: No. 1. The right rear mortar. No. 4. The left front mortar. The mortar-pit letter will be painted with its median line on the median line of the front vertical wall or interior slope of the pit and with its middle point about 10 feet above the floor. The letter will be block, 10 inches high and 8 inches wide, painted in white on circular black background 16 inches in diameter. The mortar number will be painted with its median line on the upper element of the mortar, halfway between the median circular element of the trunnion band and the face of the breech, the top of the figure being toward the trunnion band. The number will be block, 4 inches high, painted white. The tactical numbers of guns of 8 inches caliber and upward will be painted on the left half of the horizontal diameter of the face of the breech, halfway between the circumference of the opening of the breech recess and the circumference of the face of the breech. The numbers will be block, 4 inches high, painted in white. The tactical numbers of guns of caliber less than 8 inches will be so located on the gun or carriage as to be easily visible from the rear, the location on each class of gun and carriage in an artillery district being uniform and being prescribed by the district commander. The numbers will be block, 11⁄2 inches high, painted in white. Stencils for all gun and mortar batteries are furnished by the Ordnance Department. (Par. II, G. O. 51, W. D., 1906.) Citations: (a) Seacoast batteries include guns of one caliber only. (Cir. 42, A. G. O., 1903.) (b) As to former designations of pits in batteries of sixteen mortars, see G. O. 82, A. G. O., 1902. FORTIFICATIONS AT GARRISONED POSTS. 119. Repairs by Quartermaster and Engineer. Departments. When under the provisions of paragraph 1535, Army Regulations, any seacoast post or any part of it has been turned over to and garrisoned by the coast artillery, all repairs to the buildings, plumbing, water-supply and sewer systems, roads, walks, and grounds will be made by the Quartermaster's Department, governed in this work by the provisions of paragraph 1534, Army Regulations. Repairs to the fortifications, including the ramps, gutters, etc., connected thereto, will remain in the hands of the Engineer Department. (Cir. 23, W. D., 1905.) 120. Keys to be turned over.-Whenever emplacements, range-finder stations, magazines, or other structures pertaining to seacost defenses are turned over by the Engineer Department to the Artillery, all keys belonging to such structures will be turned over to the proper artillery officer at the time of the transfer. (Par. I, G. O. 172, W. D., 1905.) INSPECTIONS. 121. By district engineer, commanding officer, and artillery engineer.-The district engineer officer will make an inspection of the engineering features of each garrisoned fort within his district during the last ten days of the second month of each quarter. He will give timely notice of the dates of his intended visit to the commanding officer of the artillery district, who, with the artillery engineer of the district, will accompany him in his visit of inspection, in order that they may present their views with reference to any defects in engineer appliances and electrical equipment. Each post commander will accompany the inspectors during the inspection of his post. Defects of a minor character which pertain to the work of the Engineer Department and are plainly the result of a normal and proper use of the emplacements and engineer appliances will be repaired at once by the district engineer officer, if the balances in his hands from the general allotment for preservation and repair of fortifications are sufficient. Defects which indicate imperfections in the installation of the engineer appliances or electrical equipment, or lack of care in operating, will be jointly investigated by the district engineer officer, the commanding officer of the artillery district, and the district artillery engineer. The district engineer officer will forward at the earliest practicable date a report of the inspection to the Chief of Engineers for such further action as he may deem necessary in the premises and a copy of the report will be furnished at the same time to the commanding officer of the artillery district. Should a post commander become aware at any time, other than at a regular quarterly inspection, that a serious defect has developed in the engineering appliances or electrical equipment it will be his duty to notify the artillery district commander who will inform the district engineer officer at once in order that the correction may be made, if possible, before the next regular quarterly inspection, and upon the receipt of such notification the district |
