《明史·列传·卷六十六》
现在固原向南斜行的修筑工事即将完成，唯有花马池向北绵延二百里，应当筑十堡，而刘宪故造危言阻拦，垂成之功将被废，恳求命令刘宪掌握三边，而改换臣抚宁夏，使得以完成边防工事，办起事来也方便些。 
今固原迤南修筑将毕，惟花马池迤北二百里当筑十堡。而宪危言阻众，且废垂成之功。乞令宪制三边，而改臣抚宁夏，俾得终边防，于事为便。 
The construction work that is currently sloping southward from Guyuan is almost finished, only Huam池 extends 200 miles northward, and ten forts should be built. However， Liu Xian deliberately creates alarmist scares to obstruct it. The work that is almost completed is going to be abandoned. I beg you to command Liu Xian to take charge of Sanbian, and I will be transferred to comfort Ningxia, so that the border defense construction work can be completed. Then things will be more convenient.
