this pest. IN the vicinity of l.hs Crure
and Meeilla, was IN 1889 although IT
presence had been known for a numbe
OF years previous. During that sea-ot
the report says, the insects attacked Ia
vines ~ Judge Newcomb and DR., Bail,
who only realized half u crop, aud IN ia
following year, 1900, their entire Gro
port, they are found in great numbers /
all the vineyards examined at Las Cruce
or La Mesa.
In referring to the remedy for the pcs
under consideration, the entomolue,s
expresses the opinion that the keroser
emulsion will prove most effective, an
says: DILUTED fifteen times, It aill nj

applied by means Of force pump with
few feet OF hose, and nozzle giving

possible also that it might prevent Il
eggs from Matching, il applied earlier, d
though these are deposited beneath Il
akin OF the leaf The emulsion may
made by dissolving one half pound
hard soap IN one gallon o. hot water, al
adding this boiling hot 10 two gallons
kerosene. The mixture IL then pump,
through force pump back into the p'

have to contend with this or any 9th
formidable enemy. Up TO this time '
have been singularly free from pests
