Greenup (174), American Commercial Attache at Lima, Peru, nn 
April 7, 1936, reported that practically all Peruvian exports of cube 
are from Iquitos. For instance, during 1935 only 8,888 kilos were 
shipped from other ports - 2,644 from Callao and 244 from Paita. 
Demand for barbasco has been such as to suggest that this pro- 
duct will take a place among the more important exports of the nation. 
Exports gained from 1.8 metric tons in 1931 to 439.5 metric tons in 
1935, the United States having been the market for 100 percent of the 
1931 total. Although exports to the United States have increased from 
year to year, those to the United Kingdom, France, and Germany have 
been relatively greater. The distribution of 1935 exports was as 
follows: United States, 60 percent; United Kingdom, 15.20 percent; 
France, 14.00 percent; Germany, 10.23 percent ; and Belgium, 0.57 
percent. 
Crilley (104), Assistant Commercial Attache at Lima, Peru, on 
July 22, 1936, wrote that "Kuasco barbasco" is a local name applied 
to cube. 
"Peruvian exporters of cube ship only on the basis of 
irrevocable letter of credit before shipment. American firms 
attempting to deal direct with Iquitos merchants may find it 
difficult to protect themselves. Since the importer in the 
United States will have to pay on shipping weight the loss 
on fresh root might be heavy. No peruvian firm is known to 
be willing to snip by draft against documents with acceptance 
of the draft subject to analysis upon arrival. 
"The price per pound of guaranteed 4 percent rotenone 
content is said to be 18 to 20 cents in New York. Peruvian 
cube is sold often at 4 percent minimum content with a 
premium payable for each additional percent in proportion. 
It is the practice of some houses in the United States to 
buy entirely on the basis of 5 percent rotenone content, 
paying for nothing over 5 percent. 
"Quotations at Iquitos are not as yet obtainable 
in Lima. Iquitos firms buy cube green and dry it before 
shipment, paying, it is said, from 40 to 50 centavos Peruvian 
per kilo (10 to 15 cents U. S. C-/.). Arrivals of cube at 
Iquitos are irregular. Small lots come down the river by 
raft, canoe, and river steamers. When the demand is strong 
cube prices seem to be related with those for fish in the 
Amazon regions since the Indians and' small farmers may 
prefer to use their home-grown crop for fishing rather than 
transport it to Iquitos for sale."
