wood. The new method eliminates the former tedious procedure of debarking 
the stump and painting it with creosote. 
In wooded areas the introduction of strip scouting with small scout units 
combined into large crews and deployed in parallel lines across the strip to be 
surveyed permitted an increased rate of coverage under closer supervision than 
had been the case with the regular crew alinement. 
Tests with a number of different types of filtering spectacles resulted in the 
selection of a type of spectacle which filters out greens and emphasizes browns 
and yellows, thus making wilted or yellowed leaves conspicuous against a back- 
ground of healthy foliage. These may be of assistance in future scouting. 
To meet the need for a lightweight, extensible pole pruner required by scouts 
in collecting twig samples, several sizes of telescoping primers were con- 
structed from aluminum alloy tubing. After the pruning knife is hooked over 
a branch, a turn of the pole closes the knife and snips off the sample. When 
these are obtained in quantity, they will greatly assist in scout work. 
Form letters describing the object of Dutch elm disease survey work were 
supplied to New Jersey scouts for distribution to property owners whose prem- 
ises were entered. Signs for nailing to each tree sampled were also adopted 
by the New Jersey Department of Agriculture. 
Inauguration on January 1 of an 8-hour day to replace the former CVj-hour 
daily work period increased production, since fewer hours were devoted each 
month to conveying the crews to and from their work sites. 
Speedy laboratory determination of samples gathered by scouts was facili- 
tated by a night messenger service, whereby daily collections were delivered 
to the laboratory before work began the following morning. 
CIVILIAN CONSERVATION CORPS COOPERATION 
Although for several years men have been furnished by the Emergency Con- 
servation Work Administration for the removal of diseased and dead or dying 
elms, the contribution of this branch was more definitely organized by the 
establishment during August and September of five C. C. C. camps devoted 
exclusively to Dutch elm disease control. Early in December a sixth camp was 
constructed. The camps are located at West Milford, Raritan, and Denville, 
N. J., West Haverstraw and Highland Mills, N. Y., and near Danbury, Conn. 
Enrollees from these camps engaged in all phases of the work, including scout- 
ing, elm sanitation, and clear-cutting in swamp areas. Control activities of 
the enrollees are supervised by experienced men trained and recommended by 
this Bureau. 
SOURCES OF FUNDS 
Supplementing an original allotment of $250,000 of Works Progress Adminis- 
tration funds made on May 28, 1935, a further assignment of $2,500,000 from 
the same source was made on. July 30, 1935. This carried the work through 
until the end of the year. On June 24, 1936, work-relief funds amounting to 
$165,400 were allotted to be used for building up the scouting force at the 
beginning of the next fiscal year. Funds allotted to Dutch elm disease eradi- 
cation in the Agricultural Appropriation Act for the fiscal year amounted to 
$261,156. 
State funds appropriated for Dutch elm disease control during the year 
amounted to $12,500 in Connecticut, $50,000 in New Jersey, and $150,000 in New 
York. During July, August, and the first half of September, New York placed 
from 60 to 100 trained scouts and supervisors in the field. From September 
15 to November 15, New Jersey employed 55 men to assist in tagging dead 
and dying trees and in supervising sanitation crews. This assistance, especially 
in the supervision, added materially to the efficiency of the work performed by 
W. P. A. employees. 
Mutually helpful cooperation has been accorded the Bureau by officials of 
the three infected States, and unanimous public support has greatly assisted 
in furthering the eradication activities. 
TRANSFER OF FIELD HEADQUARTERS 
Effective April 6, the field headquarters supervising Dutch elm disease eradi- 
cation, European corn borer certification, and Japanese beetle and gypsy moth 
quarantine enforcement was transferred from White Plains, N. Y.. to a three- 
story brick building in Bloomfield, N. J. The former New Jersey district ..ili.e
