Regulations Respecting Extra= Allowance to Officers. In all cases where officers are detached on Service, which obliges them to incur expences on the road, and at places where there are no military posts, except when the Law has specifically provided for travelling expences, the following regulations are to govern in the settlement of their accounts. 1. Every officer is allowed, besides his legal pay and emoluments, shall receive a dollar and twenty five cents per day for his man and horse for each day that the officer must [stay] at a place not a military post, and when the officer is of a rank to be entitled to a servant, then the addition of twenty five cents per day for the servant and his horse. That the foregoing rule shall apply to all places but the Seat of Government, and the principal town in every State at which places the allowance to be a dollar and a half for the Officer and his horse. 2. That extraordinary cases only for which greater allowances may be indispensible be referred to the Special direction of the Secretary of War, to be attested by a certificate from the Commanding Officer by whom the officer claiming was detached on the special service, stating the reasons and circumstances. 3. That fifty cents without reference to rank, be allowed to every officer detached from one military post to another, which he may reach the same night, not less than forty miles distant: In this case it is contemplated the person can without inconvenience take his own [undecipherable] with him — 4. That the days journey be regulated by the number of miles in the following proportions, Viz: Forty miles to a day when the whole distance does not exceed two hundred miles: thirty to a day for all above two hundred and not exceeding three hundred and fifty; twenty five to a day, for all above three hundred and fifty and not exceeding five hundred; and twenty to a day for all above five hundred. 5. That these rates do not retrospect but regard future allowance only. That all past and intervening cases, upon a reasonable notice of the same, be settled on the former principle of reasonable expences according to circumstances, it being supposed that the application of a new rule may produce hardship and injustice where the service may have been performed in the expectation that practice on former occasions would prevail.
