On the road to Huancané Dr. Bronson and Frank turned aside to look at a sepulchre built of flat stones piled irregularly together. It is thought to be the earliest form of the chulpa, before the Inca architects had learned to shape their structures like the one just described. The stones were flat, some of them being five or six feet long, and correspondingly broad, with a thickness of twelve or fifteen inches. Frank made a sketch of the monument, and introduced the figure of a man standing beside it, so that its proportions could be readily seen.
