rectangular earthwork enclosed by mound and ditch. This was excavated in 1906 and Roman tiles and coarse pottery were found within its enclosure and in its mound and ditch, though not outside its boundaries.³²
   It is plain that the area of Greenwich Park contained in Roman days an important building. It is more difficult to decide what that building was. The ground plan has wholly vanished and the smaller remains are hardly distinctive enough to prove any theory. But the inscriptions, one possibly mentioning Aesculapius, the fragment of a statue, the bit (as it seems) of marble wall-lining and the list of coins ranging through all four centuries suggest, not so much a dwelling-house as a shrine planted near a road and on the top of a hill that looked far and wide over the Thames valley and the Blackheath downs. That theory would perhaps agree with the comparative fewness of coins later than the Constantinian period, since the growth of Christianity would lead to the neglect of a heathen shrine. It is, however, possible that the remains belong to a country house, and it would be rash to insist imperatively on the scanty items just cited. But one may confidently assert that nothing has so far been discovered which indicates a fort or military occupation. The earthwork, if Roman, as seems probable, may belong to a temple enclosure or a villa garden, and in its present shape is too imperfect to be taken into account as a determinant feature.³³
   26. LOWER HALSTOW.—Here traces of a hypocaust have been detected a little west of the church, and tiles and potsherds occur freely in the adjoining fields. The church also contains much Roman building material in its walls, and an embankment close by, which bounds the west side of Halstow Creek, is full of debris and has obviously been constructed from earth which was strewn with remains.³⁴
   27. HARTLEY.—What may have been the hypocaust of a bath or house was opened in March 1926 in the garden of Mr. A. J. Dennis, 5 miles south-east of Dartford, by the Rev. G. W. Bancks, Rector of Hart1ey.³⁵  The site is close to Scotgrove, where there are ruins of a medieval chapel, and it is just possible that the masonry in Mr. Dennis’s garden may be of the same period. No Roman remains were found in or near the supposed hypocaust.
   28. HARTLIP.—Scattered structures, including a bath-building extending over 3½ acres, have been uncovered in the south-west corner of a field called Lower Dane Field, near Marsborough or Meresborough Farm, ½ mile south-west of Hartlip Church, a mile south of the Roman London road, and on a cart-track leading from the village to the London road. The site is on rising ground overlooking the Upchurch marshes. The buildings were first opened in the middle of the 18th century, again in the autumn of 1845, and finally in 1848 by the tenant under the general supervision of C. Roach Smith who published the chief account.
   The plan (P1. XXIII) shows the relative position of the various buildings, the most important of which and the only buildings described in detail are those marked I, K and L, M.  I is a bath building, measuring 50 ft. by 25 ft., of a type sufficiently well known. It would seem that the room at the south-east end was the dressing-room, with a warm or tepid bath in the south-west side at E (P1. XX IV, no. 2), along the north-east wall of which a bench or step had been made of box-tiles placed on end and covered with cement, but whether the tiles were merely used structurally or were connected with the heating system is not clear. The walls and floor were plastered and coloured and at their junction was a quarter-round moulding; a lead pipe through the south-east wall drained the bath.. The relation of the small room (H) opposite to the bath with the large building K with which it appears to connect is uncertain; it is not even stated whether the two buildings are contemporaneous. The adjoining rooms A and B were heated with hypocausts, the pillars being formed of box-tiles filled with cement, and formed the tepidarium and caldarium respectively. At F was a small bath of similar construction to E, with a drain through the southeast wall. Room B contained an apse probably for a sudatorium, and the square tile-foundation opposite to it probably held a water basin, as also may that in Room G. Two furnaces and stoke-holes existed at C and D—probably for use at different times—and a smoke- or draught-hole pierced the south-east wall of room A. The walls were well built of flint and chalk rubble, sometimes in herringbone fashion, with tile bonding-courses and quoins, and were plastered inside and out.

Hübner does not say: found at Greenwich, but ‘on the Greenwich railway,’ and his ref. to Hist. Soc. Lanc. and Ches. is wrong.
