Vineyard Haven, Dec. 15. - Today has been a red letter day in the history of Vineyard Haven. The water works, the progress of which has awakened so much interest throughout the island, has been formally opened and the consummation of the enterprise celebrated in a manner commensurate with its importance. Vineyard Haven has a right to be proud, not only of its water system, but of the brilliant demonstration which signalized its completion, and of the creditable manner in which her citizens arose to a proper recognition of the occasion.
