Publisher's Synopsis
Excerpt from An Account of the Foundation and Work of the Blue Hill: Meteorological Observatory

Break down, the instruments are mostly in duplicate, and when the whole instrument cannot be duplicated, spare pieces, such as clocks, are kept on hand. The wind instruments are especially liable to accident, and when it is considered how they are strained by violent gales, and that some miles of wind pass over them each month, the necessity for good workmanship in their construction, and careful attention to their action is apparent. The Observatory was, necessarily at first, and is still to some extent, an experimental station where new instruments are tested and modified as experience may suggest.
