Declarations will be made in accordance with the instructions issued under the Pension Act of July fourteen, eighteen hundred and sixty-two, and supplementary Acts. The grade of such officers, for the purpose of determining the rates of pensions under this section, is fixed as follows: Provost marshals will rank as captains; their deputies as first lieutenants; and enrolling officers as second lieutenants. _Increased Pensions to Widows, and Orphan Children Under Sixteen Years of Age._—The second section of this act allows to those who are or shall be pensioned as widows of soldiers or sailors, two dollars per month additional pension for each child (under sixteen years of age) of the deceased soldier or sailor by the widow thus pensioned. On the death or remarriage of such widow, or on the denial of a pension to her, in accordance with the provisions of section eleven of the Act of June six, eighteen hundred and sixty-six, the same amount to which she would otherwise be entitled, under this and previous provisions, is allowed to the minor children. The number and names of the children, with their ages, must be proved by the affidavits of two credible and disinterested witnesses. The provisions of this section only include the children of the widow, and not those of her deceased husband by a previous marriage. The widows of minor children of officers are not entitled to this increase. Declarations for an increase under this section, if for the widow, will be made in accordance with form H, appended hereto; and if for minor children, according to form I. The pension certificate must be sent with all applications filed subsequently to September four, eighteen hundred and sixty-six. _Increase of Pensions under Acts prior to July 4, 1862._—All pensioners under Acts approved prior to July fourteen, eighteen hundred and sixty-two, are, by the third section of the present act, granted the same rights as those pensioned under acts approved at or since that date, so far as said Acts may be applicable, with the exception of soldiers of the Revolution or their widows. This section applies only to pensioners who were such at the date of the approval of this Act. Declaration of claimants under this section will be made in accordance with the forms previously issued under Act of July fourteen, eighteen hundred and sixty-two, and subsequent pension acts, with the necessary modifications, and the pension certificates will be returned.
