Especially all over Chalco all the cochineal cactus froze that had been planted at the order of a Spanish judge, [a constable]. The [cactus] that they were cultivating had already taken root and started to grow, but the ice destroyed it and knocked it all the way down to the ground. For a whole week it froze severely (central Mexico, 1614–1615)
