preserved. 
Another extensive area of ruined structures extends from 
the east wall of the camp to the river bank. These consist of 
a courtyard paved with rough stone slabs, at one end of Avhich 
are seven arched recesses and several associated chambers. The 
use of the recesses in the courtyard is a matter of curious con- 
troversy, many holding that they are places for the recejDtion of 
the gods of the family. The remains of a hypocaust are seen, 
and tiled hot-air flues, part of one being shown in excellent

to be hurried because of the shortness of time, but the party 
felt that they had been amply repaid for tlieir visit, and only 
longed for time to see all the wonders of Cilurnum. A rapid 
march had to be made to catch the return train to Hexham,

certain igneous rocks (porphyrites) which are found in large 
quantities as boulders in the drift deposits of Holderness and all 
alono- the Yorkshire coast. The members who arrived on Thurs-

which the basement Carboniferous beds are found resting on the 
volcanic series. Roddam Dene is a well-wooded, picturesque 
little glen, showing numerous good sections of red sand- 
stones and marls, but time did not permit of the thorough 
investigation of the lower parts of the glen, where the con- 
glomerates are probably best seen. A pretty little gorge 
was found near the head of the stream cutting through a bed
