今天读到一个神迹的故事 查了一下确实是发生过的事情
https://en.wikipedia.org/wiki/John_S._Pillsbury#cite_ref-9
During the Grasshopper Plague of 1877, Governor Pillsbury called for a day of prayer on April 26, 1877. A subsequent sleet storm killed all the grasshoppers. In Cold Spring, Minnesota, a chapel was built to honor the miracle.
