and one that would not
be likely to recur in the same way at any other point along the coast.
Nevertheless, of the entire 3,500 acres of marsh, not 100 acres remain
on which there is any breeding whatever, and that is dangerous only in
a few places and under certain abnormal conditions. Including old
ditches cleaned out, about 360,000 running feet of ditches have been
dug on the Newark marshes, partly by machine and partly by hand, and
if the work is not entirely successful, that is due to the defects
which were not included in the drainage scheme. It is a safe
prediction, I think, that Newark will have no early brood of
mosquitoes in 1905, comparable with the invasions of 1903 and 1904."

This prophecy has proved true.

_The Campaign on Long Island_

The wealthy summer residents along the north shore of Long Island,
keenly alive to the necessity of driving mosquitoes from the region
where they spend so much of their time, have attacked the problem in a
scientific, as well as an energetic way. The North Shore Improvement
Association intrusted the work to Henry Clay Weeks, a sanitary
engineer, with whom was associated, as entomologist, Prof. Charles B.
Davenport, Professor of Entomology at the University of Chicago and
head of the Cold Spring Biological Laboratory; also F. E. Lutz, an
instructor in biology at the University of Chicago. Prof. N. S.
Shaler, of Harvard University, the most eminent authority in the
country on marine marshes, was retained to make a special examination
of the salt marshes with a view to recommending the best means of
eliminating what were the most prolific breeding grounds of
mosquitoes. A detailed examination of the entire territory was made.
Practically every breeding place of mosquitoes, including the smaller
pools and streams, and even the various artificial receptacles of
water, were located and reported on. Mr. Weeks, with his assistant,
then examined each body of water in which mosquito larvae had been
found, with a view to devising the best means of preventing the
further breeding of mosquitoes in these plague spots. Finally, a
report was prepared, together with a map on which was located every
natural breeding place.

_Investigations in Connecticut_

Important investigations have been made in Connecticut by the
Agricultural Experiment Station, under the direction of W. E. Britton
and Henry L. Viereck, and the results have been most encouraging. Dr.
