celery leaf t-ags. The added agents tested were insect powder, 
lysol, petroleum, spirit, tobacco extract, and quassia. The 
following sprays killed 100 percent of the hugs within 2 hours: 
soft soap 2 percent plus lysol l/2 percent, soft soap l/8 
percent plus petroleum 2 percent, soft soap 2 percent plus 
quassia 1 percent, and soft soap 2 percent plus quassia l/2 
percent (10 bugs in the first three tests and 11 in the last). 
Soft soap alone at a strength of 3 percent killed 80 percent 
of the bugs and at a strength of 1 percent killed 90 percent 
of the bugs. Insect powder plus sulphur (2:1), Polvosol 
1 percent, alkali and kainite solution 10 percent were also 
tested and gave inferior results.

Quassia polygama (Q. excelsa Sw. , Picrania amara 
Wright) is a tall treo ( 100 feet or more) with smooth gray 
bajTk, yellow v;ood, subalternate, oval-shaped leaves, and amall 
greenish-yellov; flowers in clusters. The fruit is a 
smooth black drupe the size of a pea. There is little 
pulp and the nut covers a round kernel. Except for the 
fruit pulp, all parts of the tree are intensely bitter. 
In taste and virtues it is nearly equal to the Surinam 
quassia and is said to be safely used in all cases where 
Quassia amara has been thought proper. It is recommended 
for remittent fevers, ague, dysentery, amenorrhea, chlorosis, 
dyspepsia, and dirt eating. The dose of the bark is 15 
grains to 1 dram. A wine glass full of infusion is given 
every 3, 4, or 6 hours.
