DESCRIPTION : THIS CHART COVERS THE CHESAPEAKE BAY FROM ITS MOUTH TO JUST NORTH OF BALTIMORE, OMITTING THE MOST NORTHERN PART OF THE BAY. THERE ARE EXTENSIVE SOUNDINGS, BOTTOM CONDITIONS, SHOALS, LIGHTS AND ROUTE INFORMATION SHOWN. NO TOPOGRAPHICAL DETAILS ARE INCLUDED. SOME 47 LIGHTS ARE SHOWN IN YELLOW AND RED INCLUDING ONE REVOLVING LIGHT AND ONE LIGHTSHIP. THE DATA ON THE CHART IN NO WAY IS ATTRIBUTED TO THE U.S. COAST SURVEY BUT, SINCE A DETAILED TRIANGULATION STUDY WITH SOUNDINGS AND BOTTOM DATA HAS BEEN LARGELY COMPLETED BY THE TIME THIS CHART APPEARED, THE GOVERNMENT DATA WAS USED IN ITS PREPARATION. GEORGE ELDRIDGE WAS A FORMER MASTER OF A FISHING VESSEL ON CAPE COD AND A LOCAL PILOT, SO HE MAY HAVE HAD SOME ADDITIONAL PRIVATE SOURCES OF INFORMATION. GUTHORN NOTES THAT THE ELDRIDGE CHARTS WERE NOT SUBSIDIZED AND WERE MORE EXPENSIVE, BUT THAT THEY SURVIVED BECAUSE OF GOOD DESIGN, SIMPLICITY, OMISSION OF EXTRANEOUS SHORE TOPOGRAPHY, LEGIBLE SOUNDINGS AND NOTES, AND THE USE OF COMPASS COURSES ONLY.

ELDRIDGE'S FIRST CHART, ACCORDING TO GUTHORN, WAS PUBLISHED IN DECEMBER, 1851 WHILE HE WAS CONVALESCING AT HOME FROM AN INJURY. BEGINNING IN 1865, HIS CHARTS WERE PUBLISHED BY SAMUEL THAXTER & SON OF BOSTON AND WERE ALL LITHOGRAPHED.

DATA IS PRIMARILY FROM OBSERVATION OF THE COPY IN THE HUNTINGFIELD COLLECTION AND FROM GUTHORN.

EDITION & STATE INFO : NO THOROUGH SEARCH HAS BEEN MADE TO IDENTIFY ALL THE STATES OF THIS CHART. HOWEVER, THE HUNTINGFIELD COLLECTION HAS PHOTOCOPIES OF THREE STATES IN BLACK AND WHITE FROM THE LIBRARY OF CONGRESS AND A LINEN BACKED COPY OF THE 1871 STATE.

1ST STATE - (1868) - THIS CHART APPEARS TO BE THE FIRST STATE BECAUSE OF THE MANUSCRIPT DATA ON WHEN IT WAS DEPOSITED AND THE VOLUME AND PAGE NUMBER WHERE IT WAS RECORDED, WRITTEN TO THE RIGHT OF THE TITLE IN INK. IN ADDITION, THE TWO LATER ISSUES KNOWN TO WRITER BOTH RETAIN THE 1868 DATE IN THE "ENTERED ACCORDING TO..." STATEMENT IN THE BOTTOM LEFT. SEE CHART # 368E5.

ANOTHER STATE - (1871) - THIS IS THE CHART DESCRIBED. THE DATE IN THE TITLE HAS BEEN CHANGED TO 1871. SOME OF THE NAVIGATIONAL INFORMATION HAS BEEN UPDATED.

ANOTHER STATE - (1878) - THE DATE IN THE TITLE HAS BEEN CHANGED TO 1878. NUMEROUS CHANGES IN NAVIGATIONAL AID INFORMATION, SUCH AS NEW FOG BELLS AND THE INTERVALS AT WHICH THEY ARE STRUCK, AND ADDITIONAL FLASHING LIGHT DATA ARE MADE OR ADDED. ROUTE LINES AND DIRECTION AND DISTANCE INFORMATION ON THOSE LINES FOR SOME OF THE RIVERS IS ADDED TO THE MAIN ROUTE LINES FOR THE BAY. SEE MAP # 378E5.

ANOTHER STATE - (1879) - THE DATE IN THE TITLE HAS BEEN CHANGED TO 1879. A FEW ADDITIONAL CHANGES IN NAVIGATIONAL AID INFORMATION HAVE BEEN MADE. FOR EXAMPLE, THE EXPLANATION "STRUCK AT INTERVALS OF TWELVE SECONDS" IS ADDED AT THE FOG BELL NEAR LOWER CEDAR PT. ON THE POTOMAC RIVER. SEE MAP # 379E5.

DATA IS FROM OBSERVATION OF THE 1871 COPY AND THE LIBRARY OF CONGRESS PHOTOCOPIES IN THE HUNTINGFIELD COLLECTION.

HFC OWNERSHIP DATA : THE HUNTINGFIELD COLLECTION HAS A GOOD COPY OF THIS 1871 STATE ON HEAVY PAPER BACKED WITH LINEN, WHICH IS PARTIALLY DISCOLORED. IT HAS AN ACQ. # OF EJL012-HII AND A MDHR # OF MSA SC1399-680. THE COLLECTION HAS A FULL SIZE BLACK AND WHITE PHOTOCOPY OF THE ORIGINAL LIBRARY OF CONGRESS COPY OF THIS CHART THAT WAS DEPOSITED, ACCORDING TO A PENNED NOTE TO THE RIGHT OF THE TITLE, ON JUNE 2, 1868 AND RECORDED IN VOL. 43, PAGE 624, NO. 506. IT HAS A MDHR # OF MSA SC1399-417(REPRO). THE COLLECTION ALSO HAS 80% BLACK AND WHITE PHOTOCOPIES OF THE 1878 AND 1879 STATES OF THE CHART. THEIR MDHR #S ARE MSA SC1399-311 AND 312, RESPECTIVELY.
