the largest collection from any 17th-century colonial site in North

But archeologists have found more than objects at Jamestown. They sought
to unravel the mystery of that part of the first settlement which
disappeared beneath the eroding current of the James River during the
past 300 years. It has always been known that the island in the 17th
century was connected to the mainland by a narrow isthmus extending to
Glasshouse Point, where a glassmaking venture took place in 1608. Over
this isthmus the "Greate Road" ran, and its traces have been discovered
on the island as far as the brick church tower. As the isthmus
disappeared at the close of the 17th century, the river continued to
erode the island headward and build it up at its downstream end, so that
the western and southern shores where the first settlement had been
built, were partly destroyed. Thus, the first fort site of 1607, of
which no trace has been found on land, is thought to have been eaten
away, together with the old powder magazine and much early 17th-century
property fronting on the river.

In a series of extensive tests for any possible trace of the 1607 fort
still remaining on land, several incidental discoveries of importance
were made. One was an Indian occupation site beneath a layer of early
17th-century humus, which, in turn, was covered by the earthen rampart
of a Confederate fort of 1861. This location is marked today by a
permanent "in-place" exhibit on the shore near the old church tower.
Here, in a cut-away earth section revealing soil zones from the present
to the undisturbed clay, evidence of 350 years of history fades away
into prehistory.

Within the enclosure of this same Confederate fort was found a
