tbc Rocky Mountains in immense numbers and perished in the snow. A friend of mine 
says they were six indies deep on the snow. 
In 1876, Juno 20, Hew southeast to July 25, then drifted every way the balance <>f 
the season; did but little damage west of longitude 100° 30' west. Laid their eggs 
south of latitude 41° from Colorado at least east to 100th meridian. None north of 
this line. 
In 1877, April 25, parties coming in from Republican Valley say that the country is 
full of young 'hoppers from the bluffs south of the Platte to south line of the State; 
April 12, 1 started for Niobrara River, returned A)>ril 25; saw none on the route. 
May 12 went to Republican River, then up to the White Man's Fork; saw very few 
young 'hoppers; the people said that the heavy rain had destroyed them.

Question VJ. Our section was most severely visited in 187(>. 
Question 20. Was visited in 1873, about May 15, and did considerable damage to the 
■wheat, the only crop we had at that date; staid about forty-eight hours; was cool 
and damp while they stopped ; they traveled from southwest to northeast ; again in 
1876 (in wheat harvest), probably about July 15; came from northwest ; injured the 
late wheat, destroyed the entire corn crop, potatoes, melons, and garden truck in 
general. 
Quention 31. They always travel with the wind, i. <:., the same direct ion ; of nearly a 
calm day they travel as fast as the wind; but when the wind is strong they right- 
about face, letting the wind cany them. They always stop when the wind changes. 
In 1870 they came from the northwest, nearly covering the ground and all vegetation. 
It was a bright clear day; they staid fourteen days, eatiug everything but native 
grasses and plants most repugnant to them; they, for the first time, deposited eggs 
with us, and they hatched out this spring by the millions, bnt did not grow any, and 
consequently died when a few days old. At the present writing — five weeks from the 
first hatching — there is scarcely one to be found, and at no time were they any larger 
than when first hatched. We think the cool, wet weather is the probable cause of 
their dving.

August t), 1872. — The 'hoppers (a small flight) came down upon us, remaining about 
three and a half days, doing very little damage. 
May 28, 1873. — At about noon to-day wo were visited by any amount of Mormon 
grasshoppers ; they went to work immediately depositing their eggs, doing but little 
damage to vegetation. 
June 5. — The 'hoppers about all left to-day. In the spring of 1-74 the eggs hatched 
early and in abundance ; they destroyed some fields of small grain entirely, and some 
fields were only slightly injured. Our small grain was good, notwithstanding. 
They left us as soon as they could fly ; but on July 17, 1874, was our terrible suffer- 
ing. Legions came upon us, destroying our entire crop of corn, potatoes, cabbage, 
and all gardens without exception unless smoked day and night; some saved their 
cabbages in this way ; everything they could light on was covered; sheds, trees, and 
the earth could not be seen for them; even the cottonwoods and soft maples suffered 
considerably, the leaves being eaten off; they killed several soft maple trees by gnaw- 
ing the bark off ; bos elder they did not trouble ; on July 21, after staying with us 
five days and six nights, they left. I forgot to say they began to light down upon us 
at four o'clock in the afternoon and quit at half past six. When they left, on the 
morning of the 21st, the sun was partially obscured, so dense was the cloud of 'hoppers. 
August 6, 1876. — A day long to be remembered by us. Millions of 'hoppers lit down 
upon us, partially destroying our corn, totally destroying our gardens aud potatoes, 
doing immense damage. 
On the 13th this first flight left for the south. Between the 13th and 17th two more 
flights lit down, leaving on the 18th towards evening, as our vegetation was all gone, 
seeking for something to eat southward.

Question 23. Have not had eggs hatch here in fall. Iu 1873 the Texas 'hopper de- 
posited eggs here in June ; these hatched in about two weeks, I think. 
Ogauaixa, Keith County, June 13, 1877. 
Swarms were observed passing northward over this place on the 26th, 27th, and 
28th of May. They were flying high, did not appear to be very dense, and I have no
