eadily ascertained by examination of the older editions. After the passageof three-quarters of a century since the last map of the first serieswas completed (1887), considerable demand for copies still exists. Examinationof records indicates that well over one hundred thousand mapshave been distributed since 1900. Since the original series was published,only two major changes in format have occurred. In 1903 the overlappingsystem was changed to an edge-match series (the sheet numberswere then altered to 21 through 37); and since 1956 two additionalcolors have been added to each revision to heighten readability andcontrast.When the Atlas Sheet series was completed in 1887, a map of theState on a scale of .20 inch per mile (1:316,800) was produced. Formany years this map served in various capacities, being used to showculture (Atlas Sheet No. 18, and later No. 38), relief (Atlas Sheet No.19), geology (Atlas Sheet No. 20), forests (green overprint), watersheds(red overprint), etc.In 1898 rapid development of certain population centers indicated theneed for a large-scale map series. Field work was begun to revise theoriginal Atlas Sheet manuscripts, and in 1899 the first maps of thisseries were published by the New Jersey Geological Survey. They coverseven minutes of .latitude and thirteen minutes of longitude on a scaleof 2.64 inches per mile (1:24,000). Although a total of one hundredand two edge-matching maps would have been required to cover theState, only twenty-four were published, and revision work on this NameSheet series was discontinued over a period of years. The last newedition was published in 1944 (Somerville sheet).A larger version of the 1887 State map was published in 1915. TitledCounty and Municipality Map o/ New Jersey (Sheet No. 39), on ascale of .25 inch per mile (1:250,000), it is still published and periodicallyrevised. During the years of its existence, the base map hasbeen overprinted in various colors to show railroads, highway networks,the locations of individual Atlas Sheets and United States GeologicalSurvey Quadrangles (Atlas Sheet No. 39A) and geology (Atlas SheetNo. 40). At present, the first two overprints are not being published.After the topographic survey of New Jersey was completed, theUnited States Geological Survey .published 15-minute quadrangles ofthe State on a scale of 1.01 inches per mile (1:62,500); some revisionwork was accomplished up to about 1909, but the plan of incorporatingrevisions by State personnel into the 15-minute quadrangle maps wasnever carried out. Instead, in 1934 large-scale resurveys were startedprlmarily in the northern metropolitan area, the resulting maps beingpublished as 7_-minute quadrangles on a scale of 2 inches per mile(1:31,680). During World War II most of northern New Jerseywas mapped in 7_-minute quadrangles by the Army Map Service, witha large group (forty-one) of these sheets published at the 1:31,680 scaleand later ones (torrj.-eight) published on a scale of 2.53 inches per mile(1:25,000). In 1943 the Army Map Service converted to the 1:25,0003NEW JERSEY GEOLOGICAL SURVEY
