us _Allee
des Kanaries_ (_Canarium commune_), the boughs of which form an arched
roof one hundred feet from the ground. Leading right and left from this
central avenue run other smaller avenues, roads, and paths, conducting
to the different plots in which the various families of plants are
contained, in accordance with the system of arrangement introduced by
Teysmann. Some of these paths, especially those leading to the lower
level by the river-bank, are paved with pebbles after the manner of the
"cobbled" streets of our English villages. To this Mr. Wallace, in his
"Malay Archipelago," takes exception on the score of discomfort. I was
assured, however, that they are a necessary evil, and that the heavy
rains to which Buitenzorg was liable, made it necessary to have the
firmest kind of pathway in such places. At either end of the avenue
there are lodges, but no gates, and the gardens are left open day and
night without any fear of injury. This fortunate condition of affairs is
not unusual in Java, but in this case security is partly ensured by the
proximity of a large military force and the frequent presence of the
Governor-General.

As Dr. Treub had kindly offered to act as my guide, I found my way one
morning to his house at the early hour of half-past seven. The residence
provided for the curator is situated on the left side of the southern
entrance. The deep verandah is furnished with some brilliant groups of
flowers. Opening on to it is a little morning-room hung with some
elegant engravings--reproductions of _Salon_ pictures. Here I found Dr.
Treub waiting for me.

After a few moments' conversation we left the house and passed down the
avenue. Some hundred yards onwards, to the right, there is a stone
monument interesting to Englishmen. It consists of a circular roof
supported by pillars, protecting a funereal urn placed upon a square
pedestal. On the pedestal the following inscription is engraved:--

"_Sacred to the memory of Olivia Mariamne, wife of Thomas
Stamford Raffles, Lieutenant-Governor of Java and its
dependencies, who died at Buitenzorg on the 26th of November,
1814._"

Although the site of this monument is more humble than that of Sir
Thomas Raffles' statue at Singapore, it is scarcely less interesting;
and the repair and preservation of the stonework is secured by a special
clause in the treaty of cession. I think it was just here that Dr. Treub
turned away from the Canary Avenue,
