APPENDIX VII. 
NOTES OF A JOURNEY MADE TO UTAH AND IDAHO IN 
THE SUMMER OP 1878, BY A. S. PACKARD, Jr. 
August 14, 1878. — I left Salem, Mass., for Omaha, accompanied by Mr. Leslie A. ■ 
Lee, instructor in zoology, &c, of Bowdoin College, Brunswick, Me., as special assist- 
ant. We reached Omaha on the 17th, taking the overland train that day for Chey- 
enne. 
August 18. — The day following we saw, for the first time after leaving Omaha, the 
sage-brush and the characteristic appearances of the "plains" at Big Springs, Nebr. 
At Potter we collected along the railroad track both sexes of Caloptenus femur-vubruTii) 
and also several specimens of the genuine Rocky Mountain locust (Caloptenus spretus). 
In the evening we arrived at Denver, Colo. 
August 19. — We made an early start for Georgetown, arriving there at 12.30, and 
after lunch took horses for Mrs. Lane's "log cabin," situated near the Argentine Pass, 
at the foot of Gray's Peak. Along the road, five or six miles above Georgetown, Calop- 
tetius spretus was not uncommon at an elevation roughly estimated at about 9,000 feet 
above the sea. 
August 20.— The ascent of Gray's Peak was made in a storm of hail, thunder, and 
lightning. The insects native to the extreme summit, found by turning over stones, 
were a species of Phalangium or harvest-man, a spider and mite, together with Po- 
durae. Specimens of Caloptenus spretus also occurred under stones, benumbed with the 
cold. The workmen building the summit-house told us that they had seen a few lo- 
custs flying over the peak in clear weather. 
Upon the "Alpes," or green, flower-strown slopes of Gray's Peak, above timber line, 
about 12,000 feet altitude, Caloptenus spretus was found in abundance. 
While in Denver Mr. A. J. Bell informed us that August 14, while in the South Park, 
he saw a swarm of locusts flying east for an hour or two ; he also said that they bred 
in Snake and Bear River Valleys nearly every year, but that none were seen this year 
in Snake Valley. 
Mr. Wright told us that locusts were abundant August 12 and 13 in Estes Park at 
Ferguson's Hotel. He saw them flying in the air in "enormous numbers," so that it 
was feared that they would lay their eggs, the ground being "covered" with locusts. 
Captain Jenness told me that locusts had bred this summer in small quantities in 
Gilpin Couuty, especially on the Bear Mountains. 
August 23.— We left Denver for Cheyenne aud Ogden. At the station of " Summit," 
on the Union Pacific Railroad, we were told that the Rocky Mountain locust had bred 
in the "bottoms" near the station this year and last in sufficient numbers to answer 
for bait in trout fishing. 
At Laramie City a person told us that locusts were seen about the 6th or 8th of the 
month in the air flying towards the southeast. At Rock Creek Station we were in- 
formed by freighters that no locusts had been seen this season between the station 
and Fort Kinney, about 200 miles northward, and that in general they were less numer- 
ous this year than in 1877. No locusts had been seen about Bridger, nor in the region 
north of Cooper's Lake this season. 
A ugust 24.— While locusts had not been seen by us in passing through Wyoming they 
were abundant at Evanston, and from there to Echo. We left the train at Echo Sta- 
tion and drove to Coalville, enjoying the hospitality of Bishop Clough for two days. 
He informed us that nearly one-haif the wheat crop in Summit County had been de- 
stroyed this year by the unfledged locusts, which hatched out in the wheat fields. The 
swarms which flew into the couuty late in the season in 1877 laid their eggs in the 
cultivated wheat fields, not on the hillsides a's usual, so that the young when hatched 
could not be kept out of the wheat. When winged they 'Sew back (contrary to the 
usual rule) in a northerly course into Morgan County, whence their parents came in 
the previous year. In former years the locusts, on becoming winged, took flight iu a 
southeasterly course. We learned that at the Dairy, three miles south of Wasatch, 
locusts were very thick August 24 of this vear.
