VOL. XVI. (2) EXCURSION—-LUDLOW 115 
The Castle was erected in the 11th century, and is said to have 
been begun by Roger de Montgomery, Earl of Shrewsbury, the 
builder of the massive keep, between 1086 and 1096, and completed 
by Joce de Dinan, in the reign of Henry I. In this reign it passed to 
the crown owing to the rebellion of its possessors against the king. 
«In Stephen’s time, the then governor joined the cause of Maud; and 
in the siege that followed, the Scottish Prince, whom Stephen had 
brought as his hostage, was nearly drawn within the walls by an 
enormous iron hook. In Henry II.’s reign the castle was in the pos- 
session of Joce de Dinan. . - - - Ludlow Castle subsequently 
became the residence of Edward IV. and his infant children, the 
murderer of whom, Richard Duke of Gloucester, afterwards Richard 
-IIl., is said to have had his early education here ; here too, in 
Henry VIII.’s reign, his elder brother, Arthur Prince of Wales, died in 
1502, after his marriage with Catherine of Aragon. From that period 
it was considered as the peculiar property of the Princes of Wales or 
their deputies, ‘the Lords President of Wales, who held their Courts 
of the Marches with great dignity and splendour.” * 
The rest of the afternoon was devoted to Geology. 
The Ludlow district has been regarded as classic ground ever 
‘since the days of Murchison, but thence onwards, until a year or two 
ago, it was little visited by geologists in search of a field for original 
research. But in 1906, Miss G. L. Elles and Miss I. L. Slater com- 
municated a valuable paper on ‘‘The Highest Silurian Rocks of 
the Ludlow District.”? These authoresses thus classified the Silurian 
rocks above the Lower Ludlow:
