In English _chester_ or _cester_, in Danish _caster_ and _caistor_.
Contrast the forms Tad_caster_, Lan_caster_ &c. with _Chester_, or
Bi_cester_ and this difference becomes apparent.
Now the river Ouse in the parts about Wansford separates the counties
of Huntingdon and Northampton--in the former of which no place ending
in _-by_ is to be found, and all the _castra_ are _chester_; as
Godman_chester_. In Northamptonshire, on the other hand, the Danish
forms in _-by_ are common, and the _castra_ are _caistor_, or _caster_.
All the Danish is on one side. Nothing is Danish on the other. The
river has every appearance of having formed a frontier. On it lay the
Roman station of Durobrivis--with, probably, _castra_ on each side. At
any rate, there are, at the present moment, two villages wherein that
term appears. On the Huntingdon side is the village of _Chester_ton
(English). On the Northampton side is that of _Caistor_ (Danish).
