The Hon. Chas. Mason has entered upon his duties as Commissioner ot Patents, and we hope he will adopt the earliest possible measures to facilitate the examination of applica. tions which have largely accumulated in the Office within the past year. Inventors, as a general thing, cannot afford to remain so long deprived of protection or of a decision respecting the novelty of theirinventions. Theirs as well as the interests of the public, demand a larger examining force : no completed application ought to remain in the Office over two months. From what we can learn of Mr. Mason, we believe he possesses peculiar fitness for an office of such magnitude, and confidently predict for him a faithful, liberal, and comprehensive administration.
