so happened that a sample of soft soap containing 50 per cent of 
naphtha was sent me for trial. <A single trial convinced me of its 
merits, and 500 pounds were ordered. This soap readily dissolves 
in cold water and takes up the kerosene very readily when pumped 
through a bucket force pump. I found that the best proportion was 
1 pound of the soap to 24 gallons of kerosene. In the making of a 
10 per cent emulsion in this way I first dissolved 1 pound of the soap 
in 24 gallons of water. I then added 24 gallons of oil and pumped 
the whole through a bucket sprayer and added it to 20 gallons of 
water. 
Toward the end of the spray work Professor Close, of the Dela- 
ware station, visited me and told of the experiments which he had 
just completed with the hydrated-lime emulsion. I obtained some 
of the hydrated lime at once, intending to give it a trial, but as the 
season was then rather late and my landscape work took up my entire 
time, I was unable to conduct the desired experiments. During the 
coming spring I expect to spray extensively with the hydrated-lime 
emulsion. 
I have endeavored to ascertain the experience of the other entomol- 
ogists with Pulvinaria so as to compare results, but without exception 
the reply has come, “I have had no experience with this particular 
insect.” My experience leads me to conclude that the Pulvinaria is 
as hard to down as the San Jose scale. It also teaches that we can 
not reason from analogy as to the remedies for insects. If we have 
had no personal experience with an insect we really know nothing 
about it, and we should be extremely careful in making statements 
recommending remedies. The comment of a resident of Rogers Park, 
after the receipt of a letter reading “ remedies are not necessary, as 
the insects are rarely numerous,” was, “ He can’t make me believe 
that.” I trust that no such letters will hereafter be written. 
Mr. Titus said that there had during the past few years been much 
trouble from Pulvinaria in the Chicago city parks. He had visited 
there frequently and had found employees using sponges saturated - 
with kerosene. ‘These sponges were rapidly passed along the infested 
limbs. Apparently the method was very efficient, so far as it reached 
the scales. Those on the leaves were, of course, missed.
