MOVEMENTS OF THE YOUNG LOCUSTS. 



[Answers to question 15, circular No. 1 : The prevailing direction in which the young 

 insects traveled, and any other facts in relation to the marching of the young.] 



IOWA. 



Spirit LaTce, Dickinson County. — Young 'hoppers seem to move northward. — [Mosher 



Mount Hope, Sac County. — They staid where they hatched until they acquired 

 wings. — [Holmes. 



Lake City, Calhoun County. — In 1874 the young 'hoppers seemed to travel north. — 

 [Jack. 



Alia, Buena Vista County. — No particular direction ; mostly with the prevailing winds. 

 — [Thompson. 



Fort Dodge, Webster County. — Seems to be northward. — [Mrs. Swain. 



Dakota City, Humiboldt County. — Mostly toward the north and northwest. — [Adams. 



Estlierville, Emmett County. — In every direction, apparently hunting for food. — [ Jarvis. 



Alia, Buena Vista County. — In the pupa state they have traveled in a southerly direc- 

 tion from 11 a. m. to 6 p. m. — [Crowell. 



Fringhar, O'Brien County. — They travel in every direction in search of food. — [Long- 

 shore. 



Sidney, Fremont County.— The prevailing direction of travel is nearly east, perhaps 

 from 5° to 10° north ; this course I have decided upon from examining different schools 

 in different localities, and at various times. — [G. V. Swearengen. 



labor, Fremont County. — The locusts commenced flying due east this afternoon; yes- 

 terday afternoon flying southeast; pup8e,when traveling at all, move in a south and 

 east direction, generally following the roads. — [J. E. Todd. 



NEBRASKA. 



PlattsmoutTi, Cass County. — Toward food. — [Child. 



Pleasant Hill, Saline County. — Their line of travel depends on the surface of the ground 

 and proximity to crops. — [Abbott. 



Arago, Eicliardson County. — Northeast and north. — [Gerdes. 



Hebron, Thayer County. — Travel but little ; with the wind. — [J. W. Fitzpatrick. 



Niobrara, Knox County. — South. — [Hulliban. 



Farmers Valley, Hamilton County. — No particular direction. — [Vosburgh. 



Sunlight, Cass County.— Thej march for some field of grain and stay till fledged, if 

 good picking. — [Babbitt. 



Fonca, Dixon County. — Nearly always to the north or northwest. — [Rockwell. 



Flattsmouth, Cass County. — Southeast. — [Wheeler. 



Genoa, Flatie County. — Northeast. — [Truman. 



Burr Oak, Otoe County. — Northwest direction.— [Davidson. 



Friend, Saline County. — The young insects do not travel, except in search of foodj 

 they will not average more than three feet in 24 hours. — [Whitcombe. 



Salem, Richardson Comity. — No particular direction. 



Hooper, Dodge County. — Those hatched here invariably go northwest. — [Eisley. 



Tecumseh, Johnson County. — All directions; they go to the nearest barley or wheat 

 field. — [Holmes. 



Nebo, Flatie County. — According to promise, I give you a few observations of my 

 own in regard to the Rocky Mountain locusts within the limits of Circular No. 2. 

 The locusts are now about three-quarters of an inch long, and grow very slowly, on 

 account, I think, of the continued cold, wet weather. They have done no perceptible 

 harm, except in small spots here and there, for the last six weeks. For the past few 

 days, in clear weather, of which we have but little at a time, they move in a north- 

 west course, leaving their hatching-ground for the prairie or adjoining pieces of grain. 

 To-day we have a brisk northwest wind and cold alternate showers and sunshine, yet 

 they are striving to march on, the wind often whirling them back many feet ; but, like 

 the gritty bug that they are, they up and try it again. Some of my neighbors dug deep 

 and wide ditches, but they prove of no avail; those that do not make a clean jump 

 climb up some other way — the same as many persons try to get into the sheepfold.
