Plate LIII. View of field on Upper Chester meadows, showing 

 how the poisoned bran bait was applied after the 

 cutworms became scattered throughout the field. 

 Next to the woodland the onions are eaten out by 

 the cutworms until the ground is as clean as if 

 recently plowed. 



Plate LIV. View in same section as Plate II, showing how 

 the onions are cut out by cutworms along the 

 ditches. The onions to be seen in the field were 

 saved by the use of the poisoned bran bait. 



Plate LV. Birds-eye-view, showing how the fields are divided 

 into various sizes by ditches. 



Plate LVI. A perfect onion field on " Black Soil," with uncul- 

 tivated swamp on right back-ground. 



Plate LVII. View of the fields on the so-called " Gray Soils." 

 In the ten or twelve fields shown here a few 

 onions are left in the foreground, and also in the 

 field where the two distant figures are standing. 

 All the fields had been sown to onions. 



Pinto LVIII. The remains of an onion field on the "Semi-gray 

 Soils." A few onions are to be seen at the far- 

 ther end of the field.
