made to order. Thirty-eight coils of rope were secured from 
material authentically identified in the Bureau of Science.” The 
ropes arrived at the Bureau of Science in March, 1917. By Oc- 
tober of the same year, before there had been any insect infesta- 
tion, the laboratory work in connection with this investigation had 
been completed. The length of the rope constituting a coil varied 
from about 25 to 60 meters. Thirty-two of the fibers used in 
fabricating the ropes tested were obtained from bast-plant 
species, and seven proved to be from species which gave nonbast 
fibers. In addition ropes from two standard cordage fibers, 
namely abaca and maguey, were used for the purpose of com- 
parison. The species from which the fibers of the ropes tested 
were obtained are as follows :
