Lake Titicaca, of legendary fame, completely exhausted he 
threw himself upon some sail-cloth on the boat, and, as if 
relieved of a great burden, said with deep feeling, “ I am so 
glad, so glad. We will have no more mules, muleteers, or 
Indians ; no more annoyance, trouble, or disappointment. 
I am so tired, so tired ” ; and then quickly fell asleep. 
During the night a terrific storm burst upon them, and their 
boat struggled for hours amongst the billows. But just 
before daylight of the next morning, September 25th, 1877, 
the tempest lulled, seeming to have spent its force, and 
Prof. Orton suddenly became conscious that he was dying; 
and there among strangers, far away from his family and 
friends, gently, without complaint or a struggle, he died a 
martyr to Science. He was tenderly buried on a rocky 
island in Lake Titicaca, in sight of the scenes of his last 
expedition. A fine monument, eredfed by foreigners, on the 
summit of the island, just in front of Puno, is a fitting 
tribute to this celebrated discoverer, who will be remembered 
as long as the blue waves of this magical lake murmur 
around his last resting-place, or the Sorratta range of the 
Andes, which stand in the background, lift up their snow- 
clad peaks. 
Dr. E. R. Heath, who had been employed for six years as 
Medical Director of the Pocasmayo Railroad, one of the 
roads belonging to Henry Meiggs, was, on the return of his 
brother, Dr. J. D. Heath, who had been the assistant of 
Prof. Orton, greatly impressed with the importance of open- 
ing the Beni River to science and commerce. Two months 
afterward he left Peru, returned to the United States, and 
having prepared himself for the expedition sailed from New 
York, November 23rd, 1878, for Para. Taking the first 
steamer he ascended the Amazon to Manaos, and the 
Madeira to San Antonio, where the Madeira and Mamore 
Railroad was being construdfed under P. and T. Collins. 
Here Dr. Heath remained until July 21st, 1879, adting as 
Medical Diredlor of this road, while he carefully studied the 
climate, diseases, and natural history of the country, and 
the customs and language of the people. 
Leaving San Antonio at the latter date, he ascended the 
Madeira River to the jundtion of the Mamore and Beni, 
where he made a chacra, or clearing, and planted bananas, 
yucas, oranges, and lemons. Departing from this point 
August 20th, he ascended the Mamore, passing the mouth 
of the Itenez, a river flowing north-west from the diamond 
regions of Matto Grosso, and arrived at Exaltacion Septem- 
ber 9th, 1879. Continuing his course up the river to the
