In 1760, a relentless phalanx of army worms devoured almost every green thing in its path on its march through the Connecticut River Valley.

The crawling river of caterpillars wreaked havoc on crops from Vermont’s Northeast Kingdom to Northfield, Massachusetts.

Eerily reminiscent of a plague from the bible, the Upper Valley settlers would have starved had not wild pigeons mysteriously appeared to offer them sustenance through the subsequent months of 1760.

The crawling creatures made a gradual appearance in late July and grew in numbers and strength into September. The Vermont Journal, a newspaper from Windsor, reported, “they marched with great speed and ate up everything green for the space of 100 miles in spite of rivers, ditches, fires, and the united efforts of 1,000 men.” Some residents of the Valley called them “The Northern Army,” as they marched southward in an endless formation. A detailed account was published in Grant Powers’ “History of Coos County” (1841).

”Dr. Burton, of Thetford, Vermont, told me that he had seen whole pastures so covered that he could not put down his finger in a single spot, without placing it upon a worm. He said, he had seen more than 10 bushels in a heap. They were unlike anything which the present generation have ever seen. There was a stripe upon the back like black velvet; on either side, a yellow stripe from end to end; and the rest of the body was brown.”

When mature, they were the size of a man’s finger and moved with great speed, stopping only to devour food — often crops planted by the settlers in the Vermont and New Hampshire towns they passed through.

The worms were actually moth larvae or caterpillars, and occasional outbreaks of army worms are still reported in Vermont. While they continue to be capable of destroying crops, modern pest control methods have been able to efficiently curtail their destruction. Powers’ history records their predations:

”They filled the houses of the inhabitants, and entered their kneading-troughs, as did the frogs in Egypt. They would go up the side of a house, and over it, in such a compact column, that nothing of boards or shingles could be seen They did not take hold of the pumpkin-vine, peas, potatoes, or flax; but wheat and corn disappeared before as by magic. They would climb up the stalks of wheat, eat off the stalk just below the head, and almost as soon as the head had fallen upon the ground, it was devoured.”

One way to combat the menace was to “draw the rope.” Two men, one at each end of a rope pulled taught between them, would walk through a wheat field, the rope dislodging the caterpillars and temporarily knocking them from the stalks. The farmers soon learned that the action offered only temporary relief from the onslaught. Corn fields were reduced to bare stems in a matter of days.

In desperation the settlers dug trenches one and a half feet deep around their fields, but the interminable column filled the ditches with their bodies, and those in the following ranks soon made passage on the backs of their predecessors. The farmers waged a constant vigil and were able, by their tenacity, to save at least seed corn for the following planting season. Finally, by September, the infestation began to wane. It is likely that the caterpillars had begun their metamorphosis into the moths that were their destiny. Powers noted:

”This visitation, which destroyed the principal grains of that year, was felt severely by all the new settlements; for it not only cut off their bread-stuffs, but it deprived them of the means of making their pork to a great degree, and reduced the quantity of fodder for their cattle.

Jonathan Tyler, of Piermont, related to me, that the settlements in that town were left without the means of subsistence from their own farms. His father drew hay on a hand-sled upon the ice, from the great Ox Bow in Newbury, to support his cow the following winter. And had it not been for two sources opened for their support, they must have deserted the town.”

The first source was the pumpkins that, by custom, had been sown between the corn rows. After the worms destroyed the corn, the pumpkins grew with a renewed vigor, due to the absence of competition for soil nutrients, and the harvest was so great that the farmers of Newbury gave pumpkins to neighboring towns in such numbers that their neighbors had to build rafts to carry them home on the river.

The second source was the immense flocks of passenger pigeons that still migrated through the northeast. Samuel Peters’ 1781 “History of Connecticut” acknowledges this event.

”The inhabitants of Vermont would unavoidably have perished by famine in consequence of the devastation of these worms, had not a remarkable Providence filled the wilderness with wild pigeons which were killed by sticks as they sat on the branches of trees in such multitudes that 30,000 people lived on them for three weeks.”

The roosting birds were often clubbed to death, and their trees felled to take the unfledged squabs from their nests.

Still plentiful in 1760, the pigeons provided sustenance for the farmers of the Upper Valley. The Tylers of Piermont reportedly took 400 dozen in a matter of days.

”They carried them to Piermont, and made what is defined, in the Yankee vocabulary, “a bee,” for picking pigeons; and two or three times a week the people of Haverhill were invited down to Mr. Tyler’s to pick pigeons. Those who went had the meat of all they picked, and the Tylers had the feathers; and they made, says Jonathan Tyler, “four very decent beds of those feathers.” The bodies of those pigeons, when dressed, dried, and preserved for the winter, were very palatable and nutritious, and proved a good substitute for other meats, of which the inhabitants had been despoiled by the Huns and Goths of the north.”

Once so plentiful that they blackened the sky from one horizon to the other, the wanton slaughter drove the passenger pigeon to extinction. The last bird died in captivity in 1914.

In the Upper Valley, the following spring, the famine was followed by flood, but nevertheless, the settlers persisted, despite many having their land buried under two to three feet of silt which made the acerage unusable for two or three years. The account in Hemenway’s Gazetteer concludes, “This calamity, so soon succeeding that of the worms, was regarded by many a controversy of the Lord with his family.”

Not surprisingly, the tenacious spirit of the settlers in the Upper Valley was unbroken by famine and natural disaster, and their progeny continue to prevail on the great river. While army worms have continued to threaten crops in other parts of the country, there were no subsequent outbreaks of such proportions reported in northern New England.
