Jukes-Browne wrote that he saw a fine section here in 1884, but 
did not recognize two beds of the stone. The base was not visible, 
being four or five feet below the exposed part, according to the work¬ 
men, and he estimated the thickness of the stone as 20 to 25 feet. 
Mr. "Worthington Smith, of Dunstable, then drew attention to 
the pre-historic antiquities of the neighbourhood. They were stand¬ 
ing, he said, upon the beacon in the midst of an ancient British 
camp, the earthworks of which he pointed out. The hollow places 
around them, of which there were at least fifty in that camp, were 
the sites of the huts of the early inhabitants. In the neighbour¬ 
hood of Dunstable he had excavated some of these, and had found 
flint-implements and flakes, and in one case a skeleton. Close by 
was a square camp, which, as its shape indicated, was of Boman 
origin. 
Descending the beacon hill on the south side, the party walked 
round the Boman Camp, from the furthest end of which the mound 
is very conspicuous, though all that is seen of it here is artificial. 
Brom the Camp a further descent was made into the quarries, 
where a fine section of the Grey Chalk was seen and a few ex¬ 
posures of the Totternhoe Stone were examined. Some time was 
then spent in searching for fossils and several were procured. 
Continuing the walk on the Downs, the disused workings, now 
grass-covered, were pointed out; and a little further on was seen 
the circular enclosure known as Maiden’s Bower, the site of the 
old British town of Durocobrivse, now a ploughed field with the 
remains of the ancient rampart forming a high bank around it. 
The road now being traversed was the Watling Street, and near 
this point it is crossed by the Icknield Way. Leaving Dunstable 
on the left, the Watling Street passes the Live Knolls, a series of 
early tumuli, and here all assembled to partake of luncheon. 
From the quarries to this point the walk had been entirely on 
the Middle Chalk, in which were now seen, on the Dunstable side 
of the Knolls, extensive pits worked for lime; just below, looking 
towards Totternhoe, a coombe was traced downwards to where 
several springs issue from the Totternhoe Stone, the coombe there¬ 
fore here merging into a river-valley ; and towards Kensworth 
Hill, shallow openings, scarcely pits, by the roadside, exposed the 
Chalk Bock, which had been worked for road-metal. 
This direction was now taken, and on arriving at the highest 
point of Kensworth Hill, 800 feet above sea-level, a few further 
remarks on the geological features of the surrounding country were 
made by the Director, and the party again separated, those riding 
returning to the Live Knolls and thence by the Icknield Way to 
Ivinghoe Beacon, and the walkers continuing on the Downs and 
following the outcrop of the Chalk Bock to a pit by the road near 
the top of the escarpment above Yalence End Barm. Here at one 
time a fine section of the Chalk Bock was to be seen; but it is now 
covered up by rubble, the pit showing only the base of the Upper 
Chalk, and the next pit just below showing the upper beds of the 
Grey Chalk.
