and grow much higher. If he might be fortunate enough to pe- 
netrate into the more deeply situated districts of Bolivia, the chance 
of collecting seeds and plants was not unfavourable, as the Cali- 
saya of Bolivia, which is collected here, is the Quinine Bdivk par 
excellence. 
" The frontiers of Bolivia were soon reached. Mr. Hasskarl 
was soon at La Paz, not far from the snow-mountain at Lutchi?, 
a Bolivian frontier village, where he learned that the military order, 
forbidding the passage of the frontier, had not been revoked, as he 
had been erroneously informed. 
He was thus obliged to determine to retire on the Peruvian ter- 
ritory, which he did, with the plan of going to Sandia in an easterly 
direction, keeping along the Bolivian frontier. "With what pains 
and difficulties this expedition was attended can scarcely be con-

which our present space forbids. At the frontier places of Peru 
are often found Bolivians, who are generally Cascarilleros. For 
these the passage of the boundary was not forbidden, as it was for

Awaiting these, he went from one frontier place to another, and 
at last reached the above-mentioned Sandia, which he de- 
termined to make his head-quarters, and to which the objects to 
be delivered were to be forwarded at an appointed time, that he 
might pack them. He determined also to visit the places deeper 
inland himself, and to study, as much as possible, the Quinquina 
Calisaya. 
Meanwhile, the agreement with the Bolivians for plants and 
seeds of Quinquina-trees, for which provisions and strong drinks 
were given to those people, to load their mules and to serve as 
barter, was fulfilled, and by this means he really succeeded. While 
Mr. Hasskarl was gone from Sandia eastwards, one of the Bolivi- 
ans arrived with a very considerable number of plants. Having
