on the slightly better land in the eastern portion of the 
district ; in a track of 42 square miles south-west of Thetford 
there is but the solitary village of Elveden. It is a land of 
heath and warren, those of some size in the Norfolk portion 
numbering 25, and in the Suffolk part 18. Almost all these 
are on chalk spurs of the East Anglian Heights, and vary in 
altitude from a foot or two above the level of the alluvium 
in the river-valleys and of the fens — which close by the 
western border are + 8 ft. o.D. — to 169 feet near Thetford 
Waterworks, 170 feet at Croxton Vicarage, 179 feet at Frog 
Hill, West Wretham, 185 feet on Sturston Warren and 189 
feet where the road from Merton turns to Tottington, in 
Norfolk ; to 173 feet, half a mile south of Barnham and at 
Shelterhouse Corner, Elveden, 177 feet half a mile south- 
east of Rymer Point, 182 feet 7 A miles from Thetford on the 
road to Barton Mills, and 183 feet immediately south of 
Culford Heath, in Suffolk. Nevertheless the long heathland 
slopes rising from the valleys of the Wissey, Thet, Little Ouse 
and Lark make the apparent altitude greater than the real, 
and extensive views are sometimes obtainable. From 
Bromehill, Weeting, Ely Cathedral is plainly visible 16 miles 
distant ; from Thetford Waterworks, Ickworth Building can 
be seen at the same distance ; and Swaffham Church is also 
distinguishable from Croxton, a distance of 14 miles. The 
rivers have very few tributaries. There is none on the north 
bank of the Lark from West Stow to the fenland, a distance 
of 10 miles ; on the south bank of the Little Ouse there is 
none between Euston and the fens, a distance of 14 miles, 
and on the north bank with the exception of the Thet and 
a stream less than a mile in length at Weeting, there is none 
within the confines of the district. On the south bank of 
the Wissey, west of Watton, there are three small tributaries, 
the only one of any importance being that which rises at 
Merton and flows through Thompson and Stanford Waters. 
It is probable that surface water passes directly into the 
streams through their sandy banks or beds. Heathland pools, 
known as meres, form one of the most remarkable features 
of the district, but with these I have dealt in a previous
