A list of bench marks in New Jersey was published in 1888 in Volume I of the Final Report Series of the State Geologist. With passing years many of these have been lost by the destruction or removal of the buildings on which they were placed. In 1916 a revised and enlarged list for northern New Jersey was printed as Bulletin & of the publications of this Department. The present list gives additional marks for several counties in the central part of the State. Its publication has been delayed a year in the hope that additional funds would be available to continue this work, particularly in Camden County and counties farther south. As this seems impracticable in the near future it is best to avoid further delay, in order that these results may reach engineers and others who wish to use them as soon as possible.
