On the Banks of Plum Creek

This is an okay book written by Laura Ingalls Wilder. Laura's family's first home in Minnesota is made of sod, but Pa builds a clean new house made of sawed lumber beside Plum Creek. The money for materials will come from their first wheat crop. Then, just before the wheat is ready to harvest, a strange glittering cloud fills the sky, blocking out the sun. Soon millions of grasshoppers cover the field and everything on the farm. In a week's time, there is no wheat crop left at all.

In 1875 there was an enormous swarm of Rocky Mountain Locusts. Based on estimates from a physician, they filled an area larger than the state of California. It is now considered the largest concentration of animals and there were about 12.5 trillion insects. About thirty years later the species had become extinct. This is the fourth book in the Little House series and was written in 1937.
