ness of manufacture, starting with ore
and not with the purified metal, and
avoidance of danger to the workmen,

voted to the service of men and only
one-eighth to their annoyance It
exists in the laryal state twenty-one
days, and during that period engages in
sanitary work with ardor and thorough
ness. Wherever there is dirty water,
wherever there is filthy drain. there
the mosquito larvae are to be found in
hundreds, yoraciously devouring the
concentrating matter.-N. o. Times
