_Marford_, _Old_ and _New_, are hamlets on the river Lea. The latter adjoins the E. side of Wheathampstead village; the former lies 1/4 mile farther E.; the cress-beds, the hand-bridge over the river, and some dilapidated cottages render it a picturesque spot. On the opposite side of the road from Hatfield to Wheathampstead lies The Devil's Dyke, a long, narrow gorge most beautifully wooded. It is a favourite haunt of the nightingale, as the writer can testify. MARKET or MARKYATE STREET (31/2 miles S.W. from Luton, Beds) is a village on the high road from St. Albans to Dunstable. The church, a little N. from the village, in Cell Park, is small and uninteresting, with a chancel added in 1892. The mansion called Markyate Cell, a little farther N., is old, and occupies the site of the old Benedictine nunnery built by Geoffrey de Gorham, sixteenth Abbot of St. Albans, at the instigation of Roger the Monk, the church of which was consecrated in 1145. Cowper the poet was at school in the village, at the house of Dr. Pitman. MARLOWES is a suburb of Hemel Hempstead (_q.v._). _Marsh Moor_ lies between Hatfield Park and Mimms Park. It is a hamlet in the parish of North Mimms, 2 miles S. from Hatfield. _Marston Gate_ is little more than the station (L.&N.W.R.) for Long Marston, 1 mile S. It is nearly the extreme W. point of the county. _Mayden Croft_, or Maiden Croft, is near the source of the river Hiz, with the hamlet of Gosmore adjoining (S.E.). Some remains of a moat may be traced, which are supposed to mark the site of a nunnery. The manor is ancient; in the time of Edward III. it belonged to Sir Robert Nevill, Kt. MEESDON (61/2 miles N.E. from Buntingford) has a very ancient flint church, probably erected in the thirteenth century, but restored in 1877. The S. porch is Jacobean. The pavement of the Sacrarium is a mosaic of many coloured, vitrified tiles; it is almost unique in the county and is undoubtedly of great age. There is also in the chancel a curious monument and inscription to Robert Young, gent. (d. 1626). Most of the population are to be found at Meesdon Green, 1/2 mile W. from the church. On _Metley Hill_, between the Icknield Way and the village of Wallington, may be seen Bush Barrow, one of the many ancient mounds in the county concerning which so little is known. _Micklefield Green_ (1/2 mile E. from Sarratt Church) is near the river Chess and the Bucks border. The nearest station is Chorley Wood (Met. R.) 2 miles S.W. The district is varied and undulating. MILL END (1 mile S.W. from Rickmansworth) is on the Middlesex border, close to the river Colne. The church (modern) is late Dec. in style, and has several good stained windows. The village and parish were only formed in 1875. There is also a hamlet of this name 11/2 mile S.W. from Buckland, on the Royston road. _Mill Green_, at the N. end of Hatfield Park, is a pretty hamlet on the Lea, near the old paper mill.
