_marked tussock moth. It is practical to spray the trees so 
thoroughly that even in localities where the elm leaf beetle and the 
tussock moth caterpillars are rather abundant, there will be no 
serious injury to the foliage, and those interested in this work 
should insist upon the maintenance of such a standard. 
Gipsy and brown tail moths. The work of last year in watch- 
ing for the appearance of these insects within the borders of New 
York State has been continued. Many caterpillars of various 
species, all native we are happy to state, have been sent in by dif- 
ferent correspondents, some fearing that they had found one or 
the other of these pests. These fears, we are pleased to state, were 
groundless and, so far as known to us at the presént time, neither 
of these species has obtained a foothold within our boundaries, 
though the gipsy moth has recently been discovered at Springfield 
and Greenfield, Mass. 
Several days in June were spent in the infested territory, investi- 
gating in particular the recently undertaken work with parasites. 
Thousands of these beneficial forms have been brought into this 
country, taken to the laboratory at Saugus, reared to maturity, the 
dangerous hyperparasites destroyed and the beneficial forms lib- 
erated under conditions favorable to their multiplication. Our in- 
vestigations showed that certain of these European enemies had 
survived the winter and there is at least a fair prospect of consid- 
erable benefit resulting from this systematic importation of natural 
enemies. The situation is distinctly more encouraging than was the 
case last year. A general campaign of repression has been con- 
ducted most vigorously and the beneficial result therefrom is easily 
seen in Boston and vicinity. Furthermore, the federal government, 
through its Department of Agriculture, is cooperating with the Mas- 
sachusetts authorities in an effort to prevent the further spread of 
- the gipsy moth in particular. This latter phase of the work consists 
largely in keeping all highways free from caterpillars, so as to make 
it impossible for automobiles to carry these leaf feeders into unin- 
fested regions. The gipsy moth is being combated strenuously in 
Rhode Island and Connecticut and there is a very strong probability 
that the few insects in the last named state will be speedily ex- 
terminated. ; 
Forest insects. “There were two outbreaks the past season of 
exceptional interest. The green striped maple worm, Anisota 
rubicunda Fabr. was very abundant on sugar maples in Berlin 
and Stephentown, Rensselaer co., stripping the leaves from large
