EEPOET ON THE EXPLORATION OE BRIXHAM CAYE. 
The Pen Gallery is a small tunnel with a continuous limestone floor, and connects 
the West and South Chambers. 
The Flint-knife Gallery opens out of the right or west wall of the Reindeer Gallery 
at G4 feet from the north entrance. It is about 7 feet wide, throws off two narrow 
branches on the south and one on the north, extends almost due west for about 
50 feet, where it becomes somewhat funnel-shaped, and terminates in the West 
Chamber. 
Keeping's and Mundays Galleries are lateral branches of the South and West Chambers 
respectively, and are without any features requiring description. 
Near the centre of the South Chamber a short pillar-like mass of limestone connects 
the floor and roof. 
Of the two external entrances which open out of the West Chamber, the base of one 
is slightly above the vertex of the other. They were known as the first and second 
West Entrances respectively. 
During the excavation of King’s Gallery the entire mass of rock which formed its 
northern or outward wall, and which was estimated at one hundred tons, fell and stopped 
all further progress in that direction. 
Tlte roof of the Cavern. — The northern end of the Reindeer Gallery was an open 
cutting in the limestone without the trace of a roof for the first 5^ feet, and it had 
only a partial roof for the next 10^ feet, and terminated as an open fissure 16 feet 
south of the road. The hole through which Mr. Philp first entered was 4 feet still 
further south. Excepting in the Flint-knife Gallery, a well-marked longitudinal 
joint everywhere exists at the vertex of the roof, through some parts of which, 
especially in the Reindeer Gallery, a somewhat copious drip, quite free from earthy 
admixture, enters in wet weather. Though distinctly marked in the Steep Slide Hole, 
this roof-joint is too close fitting to allow even the passage of water. A transverse or 
north and south open fissure, about 18 inches wide, crosses the roof of the Flint-knife 
Gallery, and corresponds with the narrow lateral branches which open out of the north 
and south walls of this division of the cavern. When discovered it was filled with 
angular blocks of limestone, having fine earthy matter between them. Its situation is 
shown at “ m,” fig. 2, Plate XLIII. 
The walls of the two principal Galleries. — Vertical cross sections taken in various 
parts of the two principal galleries (see figs. A, B, C, D, & G, Plate XLIII.) show that 
the walls are very irregular, whether different sections are compared with one another 
or the outline of any one alone is considered. Of those taken in the Reindeer Gallery 
the axes are vertical (figs. A to F) ; whilst in the Flint-knife Gallery they dip or 
underlie towards the south (fig. G), thus agreeing with the joints the directions of which 
they respectively have. 
Notwithstanding this irregularity, however, “there are certain characters which the 
walls possess everywhere. For example, all their angles are rounded off; their surfaces, 
especially where they are concave, have a sort of rough polish, like that produced by
