single one. If one is careful and knocks 
down laia tramo at every attempt without 
frightening others, he will succeed iu killing 
many, otherwise they will become very wild 
and difficult to reach. They are very aptly 
named “ hawk moths ” for no falcon is more 
dexterous in fi'gbt. Of course, every captured 
moth should be destroyed, as a female often 
off an acre and a quarter of tomatoes. Dur¬ 
ing many days following, they seemed almost 
as numerous as ever, in spite of continuous 
hand picking. I have never noticed them on 
potato plants. If they feed on this plant at all 
it is their third choice of food. To entirely 
prevent injury to the crop from these insects 
would demand an outlay of more labor and

grows everywhere and is so plentiful as to 
prove very noxious in many localities, es¬ 
pecially on half-cultivated lands. It pro¬ 
duces an abundance of blooms from which 
the moths sip their evening repast, with 
Hoorn nearly as early in July as those from 
roots. 
Another good way to kill the moths is to 
take a torch of any kind—a fishing jack filled 
with pitch pine, or an oil fishing light—and, 
while one carries this through the tobacco lot, 
an assistant, with shingle or bat iu hand, can 
readily kill every moth which the light attracts

In the vigorous war of extermination many 
measures have been resorted to. and among 
them the plau of growing clumps of Even¬ 
ing Primrose—(Enothera Lamarckiaua—the 
flowers of which the moths resort to in 
great numbers at twilight, as they also do 
their long, flexible tongues. The fine, la v ge 
varieties cultivated by seedsmen, produce 
larger and more numerous blooms, and there¬ 
fore are sure to attract a large number 
of hawk moths every evening. At dusk the

Seeds of the (Enothera may be sown during

to blossom by the first of July, which is just 
the time the moths first appear on the wing. 
Seeds sown early in the spring in a hot-bed,

some entomolglsts, who assert that they fly 
only in evening and morning twilight, they are
