more. His 600-acre pea plantation was practically saved by persistent 
and energetic efforts on his part this season. All the methods from a 
practical standpoint were tried on this place, and it was found that the 
brush and cultivator method (see illustration, Pl. I, fig. 1) was the 
most effective. Forty men were therefore engaged to work in the field, 
and the 600 acres were brushed and cultivated every third day fora 
period of two weeks, and in this manner the entire field was saved, 
netting the owner from 25,000 to 30,000 cases of peas of 2 dozen each. 
It is a fact which is not questioned by those who are familiar with this 
‘plantation that had not this persistent and energetic fight been fol- 
lowed, the greater portion of the peas would have been destroyed by 
the insect. Last year the peas over the same area were broadcast, so 
there was no opportunity of fighting the pest, and as a consequence. 
480 acres were entirely ruined by it, as reported last year before this 
Association (Bul. No. 20, n. s., Div. Ent., U. S. Dept. Agr., p. 94). 
This year, by changing the method, and by a new system of fighting 
the pest, the peas have been saved. Many other illustrations of a 
similar nature could be given where we have been following this 
method persistently in this State. 
The brush and cultivator method is a simple one, and the implements 
for this method are shown in the accompanying illustration, Pl. II, 
fie. 2, which represents a field of peas which was saved by brushing and 
cultivating. We might state, however, that a field not far distant 
from the one shown in the figure, where nothing was done, was totally 
ruined by the pest. A good pine switch is used to brush the vines 
backward and forward ahead of the Iron Age cultivator, drawn by 
one horse, and in this manner the insects are covered and a very large 
proportion of them destroyed. The cultivation should not be repeated 
until the third day, as it requires usually something over forty-eight 
hours for the destruction of the aduit insects when covered with earth. 
On this plantation we also sprayed a large acreage to show the practi- 
cal side of this work, and the outfit just ready to begin work is shown in 
Pl. I, fig. 2. Suffice it to say that we have found that, no spray can be 
used which can destroy a percentage of insects large enough to warrant 
the expense of the operation. In this instance we sprayed 100 acres 
in two days, and thoroughly tested the method from every standpoint, 
using various materials. We abandoned the spraying apparatus, and 
began the brush and cultivator method, which was followed up per- 
sistently, with the results already noted. We have also used the 
** brush and pan,” as shown in the illustration (Pl. II, fig. 2), in which 
instance a bushel of lice were caught to each row, 125 rods long. 
Many natural enemies, such as parasitic and predaceous insects, have 
been found feeding upon this pest in the fields, and in this manner, no 
doubt, the number has been somewhat reduced. The most important 
factor, however, we have observed in the destruction of this pest has
