of which, he added, was of no commercial value, I. wrote to another

"The following year a scientific expedition from the Uni- 
versity of Indiana, II. S. A. , cane to Peru, for the purpose of 
studying fish-life in the sierra or mountain region. The leader 
of this expedition, Dr. Eigennan, called on no in Euancayo, and. I 
then made known to hi:.; ny ideas on Cube Barbasco and their possible 
commercial use. He purchased a quantity of Cube in Huancayo, for use 
in his fish-collecting. On his return to the States, after a trip 
in the interior, Dr. Eigennan handed over to Dr. MclndoQ a fornor 
pupil of his a few of the roots loft over. Hclndoo at that tine was 
en entomologist employed by the Washington Government. Dr. i.Idndoo 
immediately recognized the merit of cube as an insecticide end re- 
quested mo to furnish him with a further supply of roots wherewith 
to effect his experiments." 
Dennis argued that cube is superior to dcrris end Brazilian timbo. 
The price of fresh root at Iquitos in 1935 ranged from 30 to 80 ccntavos per 
kilo. In the third year a crop may be harvester! which will yield at least 
four tons for each hectare sown, which rate of production, at the price of 
30 ccntavos a kilo will give a profit of S/ . 1,200 (Peruvian soles). As far 
as land is concerned, cube barbasco can be grown with success in any part of 
the jungle where it is sufficiently hot and where the rivers do not flood the 
lands. Barbasco grows equally in sweet lands and bitter ones. A '.'weevil" 
penetrates to the heart of the stem's fresh wood and greatly damages the 
cube. 
The question of a tre.de none is discussed, Huasca ir. Spanish means 
to climb. The wore 1 cube is used in the Chanchar.ayo country, also throughout 
the Satipo, Apurirtac, Huanuco and Urubamba districts, and, as its commercial 
use started with the roots purchased in Huancayo, it was naturally employed 
by the publicity people who were endeavouring to push the sale of the Per- 
uvian root. Owing t" 1 the fact that there arc many barbascos, it is of the 
utmost importance that the product be known under a different name, and 
owing also to the fact that the term cube has been duly approved by those dis- 
tributing the propaganda matter and, moreover by the world 1 s scientific liter- 
ature, it is quite reasonable to believe that the terms cube barbasco r 
simply. cube arc the best and most adequate worrs it has been possible to find. 
It is suggested that ovens be set up at Iquitos to dry cube. This 
could be done in 3 if ays r.s compared to 3 weeks at present and even then 14$ 
water remains in the roots because of the damp atmosphere. Cube can not be 
kept for more than three months in warehouses, without the exporter being- 
sub ject to a loss of ZOfo by reason of the weevil pest, and the importer finds 
himself in the same predicament, plus the loss of a further 14$ on account of 
water. 
Young (479), American Consul General at Li. a, Peru, in October 26, 1935, 
reported that there arc severed typos of barbasco, only one of which is desired 
so far as the export trade is concerned.
