QUOTE : The Ingallses had no way of knowing it, but the locust swarm descending upon them was the largest in recorded human history. It would become known as “Albert’s swarm”: in Nebraska, a meteorologist named Albert Child measured its flight for ten days in June, telegraphing for further information from east and west, noting wind speed and carefully calculating the extent of the cloud of insects. He startled himself with his conclusions: the swarm appeared to be 110 miles wide, 1,800 miles long, and a quarter to a half mile in depth. The wind was blowing at ten miles an hour, but the locusts were moving even faster, at fifteen. They covered 198,000 square miles, Child concluded, an area equal to the states of Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont combined.49 “This is utterly incredible,” he wrote, “yet how can we put it aside?”50 The cloud consisted of some 3.5 trillion insects.
