for plat, was the same, thus duplicating the work on two different 
situations on the farm. Without goine into detail, 1 will mention 
some of the ways which the plats received treatment. Corn was 
planted deep, shallow, early, late, with an excess of seed in the hills, 
and drilled. In one plat the earth was listed over the corn just as it 
was coming through the soil. In another plat the earth was thrown 
away from the corn as much as possible, thus exposing the lower part 
of the stalk somewhat. Plats were planted with seed corn soaked in 
strong kerosene emulsion, in diluted kerosene emulsion, and in chloride 
of lime. Other seed were coated with tar and with sulphur made 
adhesive by moistening with molasses. One plat was treated with 
kainit, at the rate of 2,000 pounds per acre, just as the corn was coming 
through. Another plat was sprayed with kerosene emulsion around 
the hills as corn appeared above ground. In still another plat a hand- 
ful of tobacco dust was placed in each hill at the time of planting 
seed. 
By May 12 the corn was mostly 10 to 12 inches high and the major- 
ity of larvee were from two-thirds to full grown. At this date six- 
teen. hills from each plat were carefully dug up, the larve counted, 
and the nature and extent of the injury noted. In this work it soon 
became apparent that the various methods of treatment, except late 
planting, and the different insecticides employed appeared to have no 
appreciable effect in reducing the number of larve as compared with 
the untreated checks. Injury resulted to seed corn soaked in strong 
kerosene emulsion for six hours, about 60 per cent failing to germi- 
nate. Curiously enough, the plats receiving kainit at the rate of 2,000 
pounds per acre gave a larger per cent of larve than any of the others. 
This may have been due to the moister condition of the soil, following 
the use of this fertilizer. 
Corn planted May 4 was but little injured, by this date, the beetles 
mostly having deposited their eggs. 
‘In the case of plats, where an excess of seed (8 to 10) was dropped 
in each hill, in no case were all of the plants in a hill destroyed, suf- 
ficient plants being left for a good stand, and in most hills thining out 
was necessary. In plats where the corn was drilled the injury was 
relatively small. From this season’s work it appears to the writer that 
if bottom lands are planted to corn late, as the first of May, or, if 
eight to ten grains be dropped in each hill, injury from the Southern 
corn-root worm may be practically avoided or so distributed that the 
damage will be inconsequential. 
In discussing this paper Mr. Webster said that last fall he had step- 
ped off a portion of a strawberry bed badly infested with white grub - 
and applied kainit at the rate of 4,600 pounds to the acre, but when he 
cune to count the grubs he found more in the portion upon which he
