The observations made during the traverse, 200 miles long and 10 days in duration, between Cochabamba, on the west, and Santa Cruz, on the east, were rendered more comprehensive and understandable by subsequent work north and south of Santa Cruz, along the east front of the mountains.Our exploratory expedition left Cochabamba on December 3 and proceeded by train to Arani, the terminus of a short narrow-gauge railway, which now (October, 1921) is being extended farther eastward toward Totora. From Arani we traveled by mule train across the successive ranges of the Cordillera Oriental past Totora, Chilon, Pampa Grande, and Samaipata to Santa Cruz, which was reached the evening of December 13 (see figure 1).

The Tremadoc Slates and Associated Rocks of South-East Carnarvonshire

I. I ntroduction . T he ancient parish of Ynyscynhaiarn lies along the northern shore of Cardigan Bay, at the mouth of the Afon Glaslyn, and forms the south-eastern corner of the county of Carnarvon. The area to be described in the present paper is the country represented upon the 6-inch Ordnance Survey maps of Carnarvonshire, Sheet XXXIV S.E. (Criccieth) and Sheet XXXIV S.W. (Portmadoc), with portions of Sheets XLII N.E. & N.W. and XXXIV N.E. & N.W. to the north and south of these. It includes portions of all four quarter-sheets of Sheet 75 of the 1-inch Geological Survey map. This area is a rectangular block of some 20 square miles, and includes the townships of Portmadoc and Tremadoc (now united as the Urban District of Ynyscynhaiarn) and the flourishing health-resorts of Borth-y-gest and Criccieth. It is traversed by the Cambrian Railway, between Barmouth and Pwllheli, and is approached either by that railway or by the London and North-Western Railway (through Bangor and Afonwen), or again by the narrow-gauge railway from Ffestiniog. For its scenery the district has long been famous, and there are few British districts which can show so great a variety of tide-flat, salt-marsh, sea-cliff, sand-dune, park, coppice, meadow, cornland, bog, moor, lake, and mountain, even over an area of many times its size. The bigger hills of the district, rising abruptly almost to 1000 feet above sea-level, occur in the north and east; and while, both geologically and topographically, Tremadoc may he said to lie among the Snowdonian
