The following information is contained in Hallowed halls : Protestant colleges in old China, Tess Johnston ed., Old China Hand Press, 1998 (as previously posted by Yale Divinity School Library at http://www.library.yale.edu/div/colleges/descriptions.htm#westchina): "An initial difficulty facing the architects was the large number of grave plots, some very old, that were scattered on the more than one hundred acres of farm land just south of the city of Chengtu that had been purchased for the WCUU campus. These graves, mounds of earth built up on raised land above the general level of the water which covered the adjacent fields at rice-growing season, all needed to be transferred elsewhere."
