AREA OF THE PRESENT DEPOSIT OF EGGS. 



A line showing the eastern limit of the area where eggs are now 

 deposited in Minnesota would include (very nearly) the western 

 tier of towns in Mower county, the western part of Steele, Rice, 

 and Scott counties, the whole of Carver, the western part of Hen- 

 nepin, along the river (in Sherburne and Benton counties, and in 

 many places thickly in the timber farms,) the southern part of 

 Todd county, then westerly including Otter Tail, the southwestern 

 part of Becker, and portions of Clay counties. To the south and 

 west of this line the locusts have had possession of more or less 

 of the state from the fourth of July to the first of October, and it 

 would be difficult to specify with any exactness especially in the 

 eastern part of this area, where eggs are most or least thickly 

 laid. But the counties along the Red river from Glyndon to Lac 

 qui Parle are comparatively free from eggs, unless in the eastern 

 portions, and again many towns from Madelia westward in Wa- 

 tonwan, Cottonwood, Murray, Redwood, and the whole of Lyon 

 and Lincoln counties are almost entirely free from eggs. 



The accompanying map will show the area of eggs deposits 

 for the last four summers, but the lines must not be construed too 

 exactly. They are intended to cover generally the outside limits 

 As for the limits of the deposit during the present year, it is im- 

 possible to draw it exactly, and no doubt a few locusts will be 

 found hatching in many spots next spring which lie to the east 

 of this line. Late in the season, considerable numbers passed over 

 Owatonha to the eastward, some over Mantorville, and possibly a 

 few over Rochester, and these, perhaps, will be found to have 

 alighted and laid eggs somewhere in the southeastern counties. 

 On our borders eggs are laid in the southwestern counties of 

 Dakota as far north as Rock Co., Minnesota, aud in Iowa as far 

 east as Mower county. 



PLACES WHERE EGGS ARE DEPOSITED. 



These eggs have been deposited, as a general rule, in the vicinity 

 of cultivated fields, and in each township the extent of the deposit 

 is measured, in some degree, by the amount of land under cultiva- 

 tion. It is not presumable, at least, that wild prairies or lands 

 lying far distant from tilled fields, are extensively filled with eggs. 

 The locust is attracted and held by the growing crops, and it seems 

 to be something more than a mere coincidence that the area de- 

 vastated by the young in the spring does not become a laying-
