The United States Department of Commerce (442) in December, 1937, 
reported that cube exports from Peru were down. The total cube root 
exported from Peru for the first 8 months of 1937 amounted to 254,082 
kilograms, valued at 563,705 soles (one sole equals approximately 25 
cents, U. S.), as compared with 287,716 kilos, valued at 609,817 soles, 
in the corresponding period of 1936. 
Ho cube is shipped from the Peruvian ports on the Pacific Coa.st, 
with the exception of small sample lots of the dried root which have 
been brought overland from Iquitos, or sample lots of rotenone extracted 
from such roots in Lima. Almost all cube shipped from Peru is from the, 
Amazon River port of Iquitos and goes to the United States or Europe by 
way of the Amazon River and the Atlantic Ocean. 
The American Commercial Attache (325) at Lima, Peru, on March 12, 
1938, reported that preliminary statistics of the United States imports 
of cube root show en increase from 171,600 pounds in 1936 to 294,484 in 
1937. It is stated in Lima that the failure of cube root to obtain 
greater acceptance on the American market has been caused in some measure 
by the lower quotations offered on "Brazilian timbo and tr.e poor quality 
of the roots shipped from lauitos during 1935. It is said that in 1937 
the buyers of cube root in Iquitos were more alert in purchasing roots 
from the native planters.. The practice of analyzing the roots for 
rotenone content before shipment was established, and in some cases roots 
were dried before shipment. Foreign buyers reported that shipments 
arrived in better condition and fewer claims were in evidence.
