Present Washington county, was originally marked with milestones brought from England, every fifth of which bore on one side the arms of Baltimore and on the opposite side those of Penn; but the difficulties in transporting them to the westward were so great that many of them were not set up. Owing to the removal of the stone marking the north-east corner of Maryland, this point was again determined and marked in1849-1850by Lieut.-Colonel J.
Roman milestones and aqueducts also are found, and close by the now famous tomb of Apollophanes, with wall-paintings of animals and other ornamentation, was discovered in 1902; a description of it will be found in Thiersch and Peters, The Marissa Tombs, published by the Palestine Exploration Fund.
Many milestones belonging to the road from Carales to Olbia have been found, but all but one of them (which was seen at Valentia) belong to the portion of the road within 12 m.
A large number of milestones and other inscriptions relating to its repair at various times are known.
A similar festival was also held at the old boundary of the Roman territory between the fifth and sixth milestones on the road to Laurentum.
