of any kind which a roving life in untrodden jungles and feverish
swamps brings.

When Wallace left Sarawak after his fifteen months' residence in
the country, he left his young assistant, Charles Allen, there. He
entered my service, and remained some time after the formation of
the Borneo Company. Later, he again joined Wallace, and then went
to New Guinea, doing valuable collecting and exploring work. He
finally settled in Singapore, where I met him in 1899. He had
married and was doing well; but died not long after my interview
with him. He had come to the East with Wallace as a lad of 16, and
had been his faithful companion and assistant during years of
arduous work.--L.V.H.

The eight years spent by Wallace in this almost unknown part of the
world were times of strenuous mental and physical exertion, resulting in
the gathering together of an enormous amount of matter for future
scientific investigation, but counterbalanced unfortunately by more or
less continuous ill-health--which at times made the effort of clear
reasoning and close application to scientific pursuits extremely
difficult.

An indication of the unwearying application with which he went about his
task is seen in the fact that during this period he collected 125,660
specimens of natural history, travelled about 14,000 miles within the
Archipelago, and made sixty or seventy journeys, "each involving some
preparation and loss of time," so that "not more than six years were
really occupied in collecting."

A faint idea of this long and solitary sojourn in lonely places is
