CALISAYA-YIELDING DISTRICTS OF EASTERN BOLIVIA. 325 
Touching at the ports of Marañon and of Searra, I came with my barks 
to Liverpool. 
“To accomplish this voyage, I set off from the city of La Paz for the 
province of Caupolican, and went by land, and over the very worst 
‘roads, more than 600 miles to Rurenabaque. There I gave orders to 
construct canoes, and went up the river Beni for 200 miles as far as 
its confluence with the Bopi, a place where the ancient town of Mag- 
dalena was situated, from whence I ascended the montana from which 
the Quina was taken. 
* [ have been compelled to navigate in the following vessels : —From 
the point of union of the Bopi with the Beni unto Rurenabaque in 
canoes which only carry four or five quintals. From the point of 
Rurenabaque to the Yacuma in long waggons, drawn by oxen. 
From the port of San Cristobal, on the Yacuma, to the town of Exal- 
tacion, on the Mamore, in canoes which carry 25 quintals ; from 
Exaltacion to Serpa, in vessels (garifeas) which carry from 50 to 80 
quintals ; from Serpa to the city of Belem, on the Para, in the steam- 
boat ‘ Belem,’ belonging to Brazil. 
** All this immense journey, full of perils on the different rivers, in- 
cluding nineteen rapids of the Madera, as also through the barbarous 
or savage Indians that are met with on them,—all this I have ac- 
complished in company with my wife, whose name is Melchore Ney, 
and with whom you are already acquainted.” 
Señor Rada refers to my having had the pleasure of entertaining 
these enterprising voyagers, and showing them my collection of living 
Cinchona plants, which seemed to afford them much gratification. 
This was more especially the case, since they were able at once to re- 
cognize the plants producing the sort of bark over which so much la- 
bour had been expended. My plants were originally derived, first, from 
seeds collected by Mr. Ledger, from the district of Caupolican (or Apo- 
lobamba) ; secondly, the Calisaya verde, raised from seed procured by 
Mr. Forbes in Larecaja; in the third place, plants raised from seed 
given me by Mr. M‘Ivor, from Ootacamund. 
Sefior Rada had the goodness to present me with specimens of the 
leaves of the two sorts which had specially been the objects of his atten- 
tion, and which he calls the “ morada” and the “ negrilla,” both terms 
derived from the purple hue, more or less dark, of the under side of 
the leaves, —a colour with which the flowers harmonize, whilst the flower 
of the verde is white.
