The board is of the opinion that the provisions for voluntary deposits under Article 1.10, §17, are applicable to deposits required by federal authority and that such deposits are made under the purposes and provisions of such section, and that the statute does not prohibit additional deposits being made for special purposes, particularly those required by the federal government, and further that the statute is not an injunction as respects the board making provision by rule and regulation in matters not prohibited by statute and which are in fact a logical interpretation of statute in the board's regulation of insurance.
