CHRONOLOGY, 1878: UTAH AND IDAHO.

that some were seen between the 6th and 8th of August in the air, flying 
in a southeasterly course. At Rock Creek Station we were told by 
teamsters that there were no locusts seen this season between there and 
Fort Kinney, 200 miles north. On the whole, the Locust was more nu- 
merous in Wyoming this year than in 1877. On the day of the eclipse, 
July 29, Mr. William Oarlin, at Cotno, saw a large swarm of locusts (G. 
spretus) passing over in a course a little south of east from about 10 a. 
m. to 4 p. m., the eclipse here not being total ; they were also seen there 
three or four days after this date, flying in a northeasterly course. They 
were supposed to have bred in the Wind River and Big Horn region.* 
Locusts were also observed by Mr. W. H. Reed in Freezeout Mount- 
ains, 35 miles northwest from Medicine Bow, flying to the east in con- 
siderable numbers, August 12. We saw a few on the ground Septem- 
ber 5. Locusts were observed at Cheyenne, August 30, flying southeast.

From a letter of Mr. F. H. Williston, dated Como, Wyo., we take the 
following : 
July 29, 1878, about 11 o'clock a. m., I first saw the Kocky Mountain Locust flying 
over Como Station on a southeasterly course, with wind about the rate of 15 miles per 
hour, the temperature 80° or 90° ; continued to fly till about 3 or 4 p. m., and during 
the eclipse. A few of the locusts alighted, but none of any consequence. 
THE LOCUST IN UTAH AND IDAHO IN 1878. 
After passing through Wyoming and reaching Evanston, Wyo., the 
Rocky Mountain Locust was seen flying in the air in abundance in the 
bottoms, and continued to be seen as far west as Echo. They were also 
observed here by us September 2, on our return, at Evanston. 
At Coalville, I was informed by Bishop Clough that during this sea- 
son the young locusts had destroyed nearly one-half of the wheat crop 
in Summit County, and that when fledged they flew back (contrary to 
the general rule, as they usually keep on in a southeast course) in a 
northerly course to Morgan County, whence they came the previous 
autumn and laid their eggs; others flew towards the southeast. The 
invaders of the autumn of 1877 laid their eggs in the wheat fields, not 
in the hill-side as usual, so that the young when hatched in the suc- 
ceeding spring could not be kept out of the wheat. At the Dairy, three 
miles south of Wahsatch, locusts were very thick August 24. 
August 27 we noticed C. spretus frequently about the railroad station 
at Ogden, though they had not been specially abundant at this place 
the present year. At Logan they were abundant, flying 20 feet high, 
and at Smithfield and Richmond a few were to be seen. 
At Richmond they came from the northeast over the mountains about 
the 1st of August, none having hatched out in the spring. They 
* Mr. Carlin told us that in August, 1875, he saw at Creston au immense swarm of locusts flying in a 
southeast course from the northwest, probably from the Wind River Mountains. They were so abun- 
dant that they delayed the train, so that they had to sind the track, the men shoveling them away. In 
July and August. 1675, they were observed flying southeast at Rawlings, as also at the end of July, 
1874, flying in the same direction, as well as in the summer of 1873.— [W. H. Reed.
