Mason & Dixon, 3 Pages a Day, Read by Toby Levy
On January 1st, 2006 I began to fulfill my New Years resolution to read Thomas Pynchon's Mason & Dixon at a pace of three pages a day. I resolved to look everything up that was interesting or obscure. I took a lot of notes throughout the nine months it took to read the book. This is the result. If you find any errors, please email me at [email protected] and I'll incorporate your corrections into this text. Toby Levy pages 1-3: Page 5 reveals that the year at the start of this book is 1786, and the place is Philadelphia. This is The first numbered page in the hardcover first where Charles Mason died earlier that year. The first edition is page 6. named character is Whiskers the cat.

Edwin Danson, UK: the Work of Charles Mason and Jeremiah Dixon
The Work of Charles Mason and Jeremiah Dixon Edwin DANSON, United Kingdom Key words: Mason, Charles; Dixon, Jeremiah; Mason-Dixon Line; Pre-revolutionary History; Surveying; Geodesy; US History; Pennsylvania; Maryland. ABSTRACT The geodetic activities of Charles Mason and Jeremiah Dixon in America between 1763-68 were, for the period, without precedent. Their famous boundary dividing Maryland from Pennsylvania, the Mason-Dixon Line, today remains a fitting monument to these two brave, resourceful and extremely talented scientists. Tutored by Astronomer Royal Dr James Bradley, Charles Mason was aware of the contemporary theories and experiments to establish the true shape of the Earth. He was also cognisant of what was being termed “the attraction of mountains” (deviation of the vertical). However, at the time it was no more than a theory, a possibility, and it was by no means certain whether the Earth was solid or hollow. The Mason-Dixon Line, a line of constant latitude fifteen miles south of Philadelphia, although the most arduous of their tasks, was only part of their work for the proprietors of Maryland and Pennsylvania. For the Royal Society of London, they also measured the first degree of latitude in America. In recent years, the Mason-Dixon Line Preservation Partnership has located many of the original markers and surveyed them using GPS. The paper reviews the work of Mason and Dixon covering the period 1756-1786. In particular, their methods and results for the American boundary lines are discussed together with comments on the accuracy they achieved compared with GPS observations.

The Mason Dixon Land Survey
Historic American Land Surveys: The Mason Dixon Land Survey 4 Hours PDH Academy PO Box 449 Pewaukee, WI 53072 (888) 564-9098 www.pdhacademy.com HISTORIC AMERICAN LAND SURVEYS – THE MASON-DIXON LINE SURVEY BY: NATHAN J. WALKER, PLS Objective: As the retracement surveyors of today are called upon to “follow in the footsteps” of those original surveyors who went before, it is useful and instructive to learn how and why the early surveyors conducted their projects. It is likewise worthwhile to consider the outcomes and consequences of the early land surveys that shaped and continue to influence America. This course seeks to study the historically important Mason-Dixon Line survey, the circumstances that led to the necessity of the survey, the surveyors who conducted the survey, and the methods and techniques they employed to complete their daunting project. Also, the lasting political and cultural effects of the survey will be examined and a timeline of events relating to the survey will be presented. Course Outline: The Mason-Dixon Line Survey A.

Paths to Freedom: a Regional Underground Railroad Symposium
PATHS TO FREEDOM: A REGIONAL UNDERGROUND RAILROAD SYMPOSIUM View of the Columbia-Wrightsville Bridge, circa 1840 by W. H. Bartlett The York County History Center is hosting a two-day event to showcase recent scholarship on the Underground Railroad in south central Pennsylvania. It will provide insight into Underground Railroad activities in York County as well as connections throughout the region. The Mason–Dixon Line, surveyed by Charles Mason and Jeremiah Dixon in the 1760s, formed a 40-mile line that became the goal of freedom seekers. Assisting runaway slaves in their escape was illegal and punishable by prison time and fines, so much of the history associated with the secretive Underground Railroad movement is based upon oral traditions. Presenters will bring expertise both north and south of the Mason-Dixon Line and east and west of the Susquehanna River.

Here It Seemed, at Least in Spirit, As Were Benjamin Franklin and Charles Mason Themselves
theCelebrating Stargazer and the Surveyor homas Pynchon was there it seemed, at least in spirit, as were Benjamin Franklin and Charles Mason themselves. Others who attended this year’s annual Surveyors’ Rendezvous in Philadelphia most certainly shared the sentiment. Pynchon’s prose sets the stage for this report, in colorful passages, respect- fully shared here, from his epic novel Mason & Dixon (1997). A master of majick and mysticism in the printed word, Pynchon captures a moment of dockside Philadelphia 1763, captivating words delight one’s senses with glints of light on balls of cheese and slip- pery eel skins, musty nets creaking with cargo, boisterous seamen and hawkers of brackish-smelling shell food, bound together with the anticipation found in the postures of 35-year-old Mason and 30-year-old Dixon as they await the precious measuring instruments about to be unloaded: Philadelphia ‘Tis the middle of November, though seeming not much different from a late English summer. It is an overcast Evening, rain in the Offing. In a street nearby, oysters from the Delaware shore are being cried by the Waggon-load.

Mason, Dixon Made Mark in Carroll" Carroll County Times Article for 29 June 2008 by Mary Ann Ashcraft
"Mason, Dixon Made Mark in Carroll" Carroll County Times article for 29 June 2008 By Mary Ann Ashcraft Couldn’t you just kick yourself sometimes! What did I have to do on October 19, 2002, that was more important than watching a re-enactment of the placing of a Mason-Dixon crownstone near Harney on the Maryland-Pennsylvania boundary? Hundreds of media types, surveyors and local residents were gathered to see a 575-pound replica of an original marker lowered into position precisely on the line where English surveyors Charles Mason and Jeremiah Dixon would have sunk one about 1765. Somehow I missed that special event, and I’ll probably never see the likes of it again! Descendants of William Penn and the Maryland Calverts had been arguing over the boundary between their two colonies since Penn received his charter in the 1680s. The 40th parallel was supposed to be the dividing line, but if that had been used, Philadelphia would have ended up in Maryland! So in 1763, Charles II of England sent two of his best surveyors to settle the question. After nearly 5 years of slashing their way through primeval forests and encountering Native Americans who were not especially hospitable, Mason and Dixon finished their task of defining the boundaries between Penn’s “Three Lower Counties” (now Delaware) plus the rest of Pennsylvania and Maryland. Every mile of the boundary was marked with a stone, but at every fifth mile the surveyors erected special “crownstones” which had been brought over as ballast in their ship. Opposite sides of the 5-foot stones were carved with the coats of arms of the Penn and Calvert families, leaving no doubt about who controlled which side. -

French Street, 4th Floor Wilmington, DE 19801 FOREWORD Delaware was the "The First State" to ratify the United States Constitution but possibly is the last state to have its boundaries settled. It took from 1681 to 1934 to settle and mark most of them and still there is a part that remains to be determined. There are many unusual elements of the boundaries including a circular boundary that it shares with three other states.
