According: to Dennis (113) a. shipment of IOC kg. of cube mado by 
him in 1928 constituted the first commercial shipment of this commodi 
from Peru to the United States. 
The Imperial Institute of Great Britain (217) in 1934 reported 
the appearance in London of samples of cube and remarked, "Should supplies 
of cute root becoiae available in commercial quantities it seems likely 
that it v. ill prove a serious competitor of derris." 
The Handelsmuseum (249' of the Koloniaal Instituut of Amsterdam 
in 1936 compared experts of cube from Brazil during 1930 tc 1934, in- 
clusive with exports of derris from the Malay States and the Butch last 
Indies. These figures show an increasing use of cube. 
According to Kansanjian (234), American Vice Consul at Para, Brazil,

Seltzer (371), American Consul at Para, Brazil, reported en rotenone 
in Brazil under date of June 29, 1935. There are reported to be several 
varieties of plants commonly known as "timbo" that yield a poison used 
for killing fish, but real "timbo' 1 is scarce, except on some of the upper 
rivers. Several shipments of the roots were made in 1953 and early in 
1934, but some proved to be worthless because the natives collecting the 
roots in the interior were not acquainted with the plants that yield a 
sufficient percentage of rotenone, nor were the firms exporting in a 
position to guarantee that the roots shipped contained any rotenone at 
all. By a decree of April 3, 1954, the State of Para prohibited the 
exportation of "timbo" roots, permitting exportation of only the powder. 
However, it is reported that no such law exists in the State of Amazonas, 
but while several small trial shipments were made from Manaos in 1933, 
no firms have yet gone into the business of exporting these roots. 
The Chemical Division of the Bureau of foreign and Domestic 
Commerce, U. S. Department of Commerce (429), on June 29, 1935, announced 
that it had been informed of the interest of two Ecuadorian firms in the 
sale of rotenone-bearing botanicals to American importers.
