called the Boar, which occeurs among the “ Wonders of 
Britain ” in the Irish version of Nennius, and likewise in the 
original Latin text, as given in the Monumenta Hist. Brit. 
p- 78, cap. Ixxii :—“ Aliud miraculum est Duorighabren, id 
est, duo reges Sabrine. Quando inundatur mare ad sissam 
in ostium Sabrin®, duo cumuli spumarum congregantur 
separatim, et bellum faciunt inter se in modum arietum : 
et procedit unusquisque ad alterum, et collidunt se ad 
invieem. Et iterum secedet alter ab altero, et iterum 
procedunt ex uno cumulo super omnem faciem maris. In 
unaquaque sissa hoc faciunt ab initio mundi usque ad 
hodiurnum diem.” “ Another wonder is Duorighabren, 
that is, The two kings of Severn. When the sea is poured 
into the mouth of the Severn to a full head of water, two 
heaps of surf are collected on either hand, and make war 
against each other like rams: and each goes towards the 
other, and they dash against each other, and separate 
again, and then flow from the one heap over the surface 
of the sea. This they do at every full head of water, 
from the begining of the world to the present day.” 
In the Anglia Rediviva, or History of the Motives, 
Actions, ete., of the Army under the Conduct of Sir 
Thomas Fairfax, by Joshua Sprigge, m.a. (1647), this 
phenomenon is called by another name—the Eager ; and 
General Cromwell is described, during the siege of Bridg- 
water, as narrowly escaping “a sudden surprisal ‘of the 
tide called the Eager,” while going over the river to view 
the posts on the other side.
