discovered as elms were being removed in the vicinity of previous 
infections in the [ndianapolis area. Initial clean-up work in Athens 
was completed in January. The sanitation area in the vicinitj of 
Wiley Ford, W. Va., and Cumberland, Md.. followed the Potomac 
River between Pinto and Spring Gap, Md. 
Our of the largest sanitation operations in the infected area was 
carried on in a large swamp in Patterson Township, Putnam County, 
N. V. Over L 0,000 elms of al] sizes were removed from this L,500-acre 
swamp. All elms within a 500-foot radius of an infected tree in the 
-urn h end of i In- swamp were pinned. 
[ntensive elm-sanitation work was performed on all elm trees within 
a mile of the focal points of the disease in Dutchess County, N. Y. 
Following the disastrous hurricane that swept over part of New 
England on September 21, sanitation crews in Connecticut wer< 
• I to a rapid clean-up of the uprooted elms, trees with weakened 
branches and hanging branches, and elm debris that furnished ideal 
conditions for large increases in the insect carriers of the disease 
fungus. Most of this material was destroyed before the possibility of 
beet If emergence in May. 
Tests were made to develop larvicidal material that may lie used to 
destroy elm bark beetles infesting piles of elm logs that owners wish 
to keep under fuel agreements and will also serve a- a repellent to 
these beetles when sprayed on freshly cut green logs that will upon 
drying become attractive to migrat ing beetles. Promising results were 
obtained with orthodichlorobenzene-naphthalene emulsion. 
There were fewer fluctuations in the W. P. A. personnel throughout 
the yea:- than previously. The number of workers ranged from 2,800 
to 3.400 during the scouting season of 1938. From 2,900 to 3,300 men 
were retained in the eradication and sanitation activities until March. 
The first week in April the force was increased to approximately 
and at this figure it was maintained for the rest of the year. 
SOURCES OF FUNDS 
Fund- for operation of the eradication project were derived from 
a regular departmental appropriation of S37*.4s9 and supplementary 
allotments made by the Works Progress Administration. The total 
was $2,957,500 for field work and $51, 1st) for administrative expense-. 
A further item of $100,000 was included in the Second Deficiency Ap- 
propriation Act of May 2, 1939. for the employment and training in 
mid-June of a Large scouting organization. 
Appropriations and allotments made by States engaged in coopera- 
tive eradication work amounted to $7,985 in Connecticut, $38,18 
New Jersey, $154,195 in New York, and $500 in Maryland. An esti 
mated $5,000 from a State joint fund for Dutch elm disease, Japanese 
beetle, and European coin borer control was expended for Dutch elm 
disease work in Indiana. Two noninfected States, Massachusetts and 
Rhode Island, allotted $5,000 and $500, respectively, to Dutch elm 
disease research and surveys.
