On April 10, 1877, in response to an expressed desire of various religious bodies, Governor Pillsbury appointed the 26th of that month as a day of fasting, humiliation, and prayer: “In the shadow of the locust plague,” said he, “whose impending renewal threatens the desolation of the land, let us humbly invoke for the efforts we make in our defense the guidance of that hand which alone is adequate to stay the pestilence.” The day was observed in a goodly number of congregations, but there was no great and general humiliation of the people, and there was no immediate evidence of supernatural interference. The infernal brood grew wings and began their aerial excursions in various directions. In the last days of June the swarms began rising high in the air and taking flight on different bearings. In the course of sixty days all had so risen and flown out of the state to unknown destinations. Although they had wrought damage equal at least to that of any previous year of their residence in Minnesota, the state as a whole harvested the greatest wheat crop in her history,—30,000,000 bushels, of sixty-three pounds to the bushel. In spite of the ruin wrought in so large a portion of her territory, and of minor and ordinary losses, the period in view was one of prosperity. The population, which had risen from 439,706 in 1870 to 597,407 in 1875, increased to 780,773, according to the census of 1880. The wheat crop, which had been 30,000,000 bushels in 1877, touched 40,000,000 in 1880. The most striking evidence of material development is seen in railroad building. In the four years 1873-76 but 87 miles had been added to the 1900 miles of construction in the eleven years ending with 1872. This mileage was increased in the six years beginning with 1877 to 3278; 446 were added to the St. Paul and Pacific (now Great Northern) system. * * * * *
