MOSQUITO: PEST 
MEANS: OF EXTERMINATION SUBJECT 
oF LECTURE AT MANCHESTER 
Last Nicut. 
T THE suggestion and under the 
auspices of the Manchester Par- 
ent-Teacher association, a free lec- 
ture on “The Extermination of Mos- 
quitoes” was arranged by the North 
Shore Association for the Extermin- 
ation of Mosquitoes, and given last 
evening at the Town hall,. Manches- 
ter. The attendance was only fair, 
about 200 being present.- Earl M. Har- 
vey, an engineer, who has done much 
practical work along this line, was 
the speaker, and his address was .1- 
lustrated by stereopticon views. He 
was introduced and _ followed by 
Walter D. Denégre, the president. of 
the association. 
Mr. Harvey said at the outset that 
there are two reasons for extermin- 
ating mosquitoes. First, their pres- 
ence is not only a promoter of dis- 
comfort, but also of ill-health and 
disease; second, they tend to decrease 
land values. 
The first illustrations showed. the 
mosquito in the act of biting, and in 
this connection Mr. Harvey said: 
“Of the mosquitoes, it is the fe- 
males that bite. Human blood is too 
thick to be taken into the proboscis, 
so they inject a poisonous serum, 
which sufficiently thins the blood. It 
is not the proboscis, but the serum, 
that causes the sting and the white 
rings about the bite and the swelling. 
The transfusion of diseases is com- 
pleted by the carrying of the serum 
from one person to another.” 
All. mosquitoes are bred in water, 
continued the speaker, but of the 
many varieties found in the. United 
States and the world, the inland and 
salt water swamp mosquitoes may be 
used for convenient classification. 
Mosquitoes of the first-named class ° 
lay their eggs on the surface of the 
water in egg boats, which contain 
from 200 to 300. eggs. In the warm- 
ness and stillness. of the water tne 
larvae develop, These feed on juices 
and air through the laval tubes. The 
‘next stage is the pupa and the mos- 
quito exists in this form for only a 
few days longer, when it becomes a 
full fledged mosquito. The males 
hatch first and collect in swamps 
where they await their mates, Their 
life is only about 48 hours, while that 
of the female is sometimes as long 
as three months. 
Most of the pictures which. were 
Nov.19, 1985, 
Bes ae pear a ok 
shown were taken in New Jersey, 
where the commission for the exter- 
mination of mosquitoes has had a fine 
field for work and has accomplished 
a corresponding amount. The first 
picture to deal with the best methods 
of permanent extermination was a 
back yard in Summit. In the first 
view the stagnant water; which was 
a prolific breeding place ‘for mosqui- 
(eee was shown, "and in the second, 
the land filled in, making the place 
not only a benefit ‘to the owner, Dbitit 
also to his neighbors. Such land can 
be filled in in less time that it takes 
the mosquito to mature. A brook 
clogged with rubbish was also shown 
before and after cleaning ‘and grat 
ig. In the latter case, care must tx 
taken that the edges are clean-cut ~-o 
that there will be no ragged edges in 
which the eggs may be laid. In the 
outskirts of cities where the rents 
are low and landlords feel little ob- 
ligation to take proper caré of the 
land are favorite haunts of the ‘mo- 
squitoes. Attention to proper draia- 
age will not only better the health of 
the tenants in such a neighborhood, 
but will greatly increase the value of 
the property. Sometimes heavy 
rains will fill unfinished cellars, which 
cannot be drained; and then ‘the: oil 
treatment is the only method that can 
be applied. Defective drains wil 
many times leave pools of filth where 
mosquitoes may increase in peace 
The speaker expressed it as his opin- 
ion that mosquitoes were useful for 
one purpose only, as telltales that 
such spots exist. te 
Mr, Harvey-told-of an interesting 
case, which he investigated in Green- 
wich, Conn., upon receiving a com- 
plaint from a hotel that the mosqui- 
toes from a neighbor’s pond were so 
numerous and so troublesome that 
they threatened to drive away the 
guests. Upon looking into the matter 
it was found that the pond in ques- 
tion was upon a nearby estate, and 
was 7 feet deep, walled in by stones 
and stocked with fish. There were 
no mosquitoes. The only source of 
mosquito breeding within 800 feet, of 
the hotel was near its own back door 
where two barrels. were thick with — 
larvae, 
Oiling is not a practical method of 
getting 4d of mosquitoes, because it 
ig expensive for large tracts and then 
only temporary. About 3% barrels 
of kerosene or crude oil are required 
for an acre. If such land could be 
drained, or ditched, it would be valu- 
able. for raising good hay or crops. 
The salt water mosquitoes are 
greater travellers than the. inland 
variety and will travel as far as 20
