4.06 REPORT—1899. 
Ty Newydd Caves.—Report of a Committee consisting of Dr. H. 
Hicks (Chairman), Rev. G, C. H. Potuen, 8.J. (Secretary), Mr. 
A. Strawan, Mr. HE. T. Newton, Mr. G. H. Morton, and Rev. 
HE. R. Hutt, 8.J., appointed to investigate the Ty Newydd Caves, 
remeirchion, North Wales. (Drawn wp by the Secretary.) 
In addition to those mentioned in former reports on this exploration ! as 
having given us assistance, we have to acknowledge the kindness of Mr. 
D. L. Paterson, of Aston Park, Birmingham, and of Mrs. Sutton, of 
Market Drayton, who gave us permission to excavate on their property, 
and of Mr. John Griffiths, of Mold. 
The principal work done during the past winter and spring has been— 
(1) In the eastern cave. 
(2) In the northern portion of the western cave. 
(3) A trial shaft was also sunk in a cave 200 yards 8.-W. of 
Ty Newydd, on the same hillside. 
(1) The eastern cave consists of a true cave tunnel with oval section, 
and a rock floor measuring, on the average, 8 ft. by 5 ft. in cross section, 
and extending 35 ft. at one level in the direction N. and 8. 
At the northern extremity there is a passage to the W. 8 ft. long and 
6 to 8 ft. across, connecting it with an oval chamber 23 ft. by 8 ft. and 
18 ft. to 24 ft. high. The entrance is situated in the upper portion of 
this chamber on the western side. 
This cave has an outlet at its southern extremity, when it turns 
sharply to the N.-E. with a sudden dip of nearly 45°, which prevented 
further excavation. 
At the top of the first chamber from the entrance there were some 
small beds of gravel, which are described and figured in the ‘Q.J.G.S.’ 
February 1898, p. 124. The lower part of this chamber, as well as the 
passage aud tunnel beyond, was filled almost exclusively with laminated 
sandy clay, containing a few fragments of stalagmite. It is not there- 
fore considered necessary to reproduce in this report any of the measured 
sections taken in this part of the work. 
(2) The northern portion of the western cave runs in the direction of 
the gully separating these caves from those of Ffynnon Beuno and Cae 
Gwyn. 
After passing across the old quarry floor behind the cottage of 
Ty Newydd, the cave runs under a garden on the northern slope of the hill. 
For 6 ft. we found here a roof of rock, but beyond that distance there 
was only a fissure covered by boulder clay. 
As we obtained permission to explore this part of the cave on con- 
dition of our doing no permanent injury to the surface, we endeavoured 
as far as possible to tunnel under the drift, which, however, proved a very 
unsafe roof to our excavations. 
To the distance of 33 ft. the average width of the cave was 2 ft. to

British Association, 1898. Not published.
