The Flint Industries of Bapchild
During the autumn of 1927, Mr. S. Williams, of Murston, observed palaeolithic implements in a gravelly deposit underlying the brickearth in the pit which lies west of Haywood Farm, Bapchild. He kept a watch on the site, and, shortly after his first finds had been made, a small quarry was sunk in the bottom of the brickpit. This exposed the sub-brickearth deposits in section, and here Mr. Williams, assisted by Mr. T. Revel and other keen workers, carried out excavations, by permission of the owners of the property, Messrs. Smeed, Dean & Co., Ltd. Their labours were rewarded by a haul of more than four hundred artifacts, of Le Moustier type. The brickearth dug at Bapchild is placed in a wash-mill and converted to slurry, in which state it is pumped to the brickworks. The wash-mill is periodically cleaned out, and from the accumulation of stones that, at such times, is removed from the mill, a number of flakes of post-Le Moustier form have been found. These obviously came from the brickearth, but none had hitherto been found in situ . Towards the end of 1928 Mr. Williams was joined in his work of implement hunting by Mr. E. A. Mount, of Sittingbourne, whom he advised to give special attention to the brickearth in an endeavour to discover the source of the flakes that had been found in the wash-mill.
The Inca Occupation of the South Coast of Peru
like the others, however; it forks into several nearly parallel ravines of which the largest are Huayuri, Rio Grande-Palpa, Ingenio (called Collao in ancient times), Nasca proper (the ancient Caxamarca), Taruga, and Poroma. Due to peculiarities of the local topography, the irrigated areas in Ica and the ravines of Nasca are located inland, at the foot of the mountains, rather than at the mouths of the rivers as is more usual in Peruvian coastal valleys. No sharp natural or cultural boundary separates the valley of Chincha from the valleys of Cafiete (ancient Huarco and Runahuana), Asia, and Mala, the next valleys going up the coast to the northwest. At the other end of the area we are considering, however, there is a sharp break; beyond Yauca the Andean foothills reach out to the sea, natural conditions are quite different, and there are important differences in the archaeological picture as well. The historical sources which mention the south coast are not particularly helpful, except in so far as they provide us with a few dates. To begin with, no chronicler gives an explicit account of the political organization of the south coast at the time it came into contact with the Incas. It can, perhaps, be inferred from Cabello Balboa's statements about common policy toward the Inca invaders that there was some sort of political connection between the valleys of Mala, Cafiete, and Chincha, but the connection need have been no more than a temporary military alliance. Cabello makes no mention at all of Pisco. The valleys of Ica, Nasca, and 125
