Map of Pennsylvania & the Parts connected therewith; To the Legislature and the Governor of Pennsylvania; This Map is respectfully Inscribed by Reading Howell

One of the earliest maps to show the entire State of Pennsylvania. This map by Reading Howell is the second state of a reduced version of his larger 4-sheet Map of Pennsylvania. The map has a lengthy copyright notice in the lower right. The map shows roads, trails, towns, settlements, Counties, Surveyor Districts, creeks and rivers, portages, canals, some topographical features (hills and mountains), and a compass rose on the left upper region.
There is some hand outline coloring of a couple of waterway routes; One from Pittsburg to Le Boeuf along the Allegeny (Allegheny) River and French Creek. Another route from the confluence of the Allegeny (Allegheny) River and the Kishkemanetas (Kiskeminetas) River to the Conemaugh River then via portage to Franks Town Branch, then a short stretch along the Susquehanna River to Swatara Creek, then via a canal to Schuykill River finally reaching Norris Town just outside of Philadelphia. An interesting note is the post-map-printing labeling of Lebanon and Myers T (Myers Town) which appear to define the termini of the short canal between Swatara Creek and the Schuykill River. This is essentially a waterway route from The Delaware to Lake Erie.
According to Wheat & Brun (443), this map was published in Schuykill and Susquehanna Navigation, 'An Historical Account of the Rise, Progress and Present State of the Canal Navigation'.
This map was engraved by James Trenchard as indicated by a notation in the lower right margin.

"This is the best map of Pennsylvania to appear in the 18th century, and the first to show its exact boundaries" - Wheat & Brun.
