largely on experiments made in this city
which substantiate the figures of the
health department concerning the capac-
| ity of the fly for reproduction. The sec
| ond reason is in the remedies and pre-
ventiveS suggested.
An interesting section OF the bulletin
is on the subject of what cities and
towns can do to eliminate the pest. The
conclusion reached in the discussion of
this subject is that what remedial ex-
Fermentation already has been conducted
has proven that cities and towns may re-
duce the numbers Of the annoying and
dangerous insects so greatly as to render
them of comparatively slight account.
According to DR.. Howard, experiments
! In Washington have shown that the To-
cal climate provides an abundance OF
| time for the development Of from twelve
| to thirteen nerations Of the fly within
| a single season. The Department OF Az
rtculture expert found that In midsum-
mer in this city. female fly lays about
100 eggs at a time. which hatch in eight
hours, the larval period lasting flve days
| and the pupaI five days. making the to-
| tai time for the development or the gen
Grafton ten days.
Time for Five Generations.
These figures agree with those given
out by DIR. Murray of the health depart
ment, who. using them as a basis. esti-
mated that there remains between now
and the end Of the season. or October
1. SUFFICIENT time for the development of
five generations.
Computing the results Of The Stars
campaign to date. DR.. Murray yesterday
estimated that population of something
like twelve trillion flies has been pre-
vented from coming into existence be-
tween the present time and the end of
the season as result Of the slaughter
Of more than two million insects already.
| This figure. OF course, rests on the as
sumption that half of the flies killed SO
| far were females.
The pest population prevented from
coming into existence it is estimated, is
| so large that II the flies were placed in
| q line they would extend around the
world twenty times
Effective screening is given first place
| among the most effective remedies sug-
sested by Dr. Howard. Cleanliness, how
| ever Is the dominant note of the sug-
gestions.

ard "even under existing circumstances.

| numbers Of the house fly. and, in fact,
most household insects are less attracted

District Regulations Commended.
The bulletin is featured with illustra-
| tons OF the different kinds of flies. 1t
lays stress upon the fact that the health
departments of cities may abate the fly
nuisance, referring to the District of
Columbia regulations which. 1t is said

communities
