Compound, 1 part; water, 18 parts ; 93 gallons diluent; examined 5 
days after. Nearly alltheinsects dead to 14 inches in depth, but most of 
the eggs looked bright yellow and no doubt will hatch. Behind the 
thick bark near the top, where apparently the solution did not penetrate, 
a number of young lice were found alive. 
Compound, 1 part; water, 20 parts; 104 gallons diluent; in holes 
4 feet in diameter. An examination 5 days later showed the fluid 
had penetrated the ground on plants 154 or 20 inches from original 
surface. All the insects were destroyed 13 inches in depth and but 
very few living 3inchesdeeper. This solution seems to work best of all 
this series, but it is doubtful if the eggs will be affected by it. 
ComMPounD No. 2.—Caustic soda, 98 per cent., 1 pound ; resin, 10 pounds ; 
water to make 124 gallons ; compound costing 25 cents. 
Compound, 4 pints; water, 4 pints; in hole 4 feet in diameter; 5 
gallons of water added 1 hour later and the same quantity next day. 
Very few dead insects were found upon this plant, and none living. 
Not sufficient to show proper result. 
Compound, 4 pints; water, 2 gallons; 5 gallons of water added 1 hour 
after and 5 gallons the following day. Examined plants 7 days later. 
result very satisfactory, hardly any living phylloxera as far as the fluid 
reached. After examination 5 gallons more water were added and 
again examined a week later, when no living insects could be found to 
a depth of 18 inches. 
Compound, 4 pints; water, 10 gallons. Destroyed insects to about 8 
inches in depth and but few below this. 
Holes only 2 feet in diameter; 5 gallons of water in same first, and 
solution 1 hour later in the four succeeding experiments. 
Compound, 4 pints; water, 45 gallons; examined 15 days later. De- 
stroyed insects and eggs as well, which had become very dark. Occa- * 
sionally a live specimen running about. 
Compound, 3 pints; water, 44 gallons. Examined 13 days later and 
found all insects dead that had been reached. 
Compound, 24 pints; water, 373 pints. Hxamined13 days later. A . 
piece of root about 10 inches deep one-halfinch in diameter by 6 inches 
long and completely covered with phylloxera showed but one single 
living young, probably hatched from egg after application. 
Compound, 2 pints; water, 435 gallons; also examined at the end of 
13 days. All insects to 8 inches below ground or 14 inches below orig- 
inal surface were destroyed, as well as a large part of the eggs. Oc- 
casionally a living young was found wandering about. 
Four other experiments were made with this compound, using 1, 2, 3, 
and 4 pints in 20 of the solution, the ground having 4 hours previously 
been saturated with 5 gallons of water in each case. Examined 12 days 
after; results were not good with 1 pint but were progressively better 
with the other three. Applied 4 gallons more water on plants where 3
