156 small canals. Sculptures of this class occur from Bolivia to Columbia. Lower down, at Samiapata, are niches cut in the rock, and buried near them are inscribed stones. Similar ones, and less elevated, where the Cordilleras separate the territory of Chaco from Chiriquanes, occur in a real desert, and being on a declivity, have escaped the alluvial burial of the first.

W., sends the following report: Along the east shore of Cayuga Lake, New York, occur many relics of aboriginal populations. On the beach are found multitudes of notched sinkers. On the points these relics are most numerous. Several burial places have been discovered; one of them is on a small island opposite the village of Union Springs. The skeletons rest on a substratum of rock, about 2 feet below the surface. A large number of skeletons were unearthed about one mile north of Union Springs and 200 feet from the lake. They were promiscuously buried in a pit under about 2 feet of fine black earth, those of men, women, and children being intermingled. The skeletons of males indicated men of large size and great strength. No relics occurred in the pit.
