The old Peruvians were great potters and thousands of their old water vessels and food dishes, which were buried with the dead, have been dug up. These had curious forms and were often adorned with colored patterns. Some of these jars were shaped like human faces, human figures, or animals. Sometimes they were “whistling jars,” which were so made that they whistled when water was poured in or out of them. The old Peruvians were skilled in working copper, silver, and gold, and made many ornaments and figures in these metals.
