The burial cave is a very small one, not over 8 meters from 
the entrace to the back wall, and not large enough to allow a 
person to stand upright init. It is located on a shelf about 100 
meters to the north of the living cave and perhaps 10 to 20 
meters higher up. There is a very narrow ledge of rock leading 
up to it. Within this cave was found a heap of human bones 
among which there were forty-four human skulls. Here also was 
a head box about 1 meter long which would hold a row of five or 
six skulls. The head box was made of wood resembling molave, 
but was in a bad state of decay. This box had handles carved 
to represent the head of some animal, possibly a crocodile or a 
horse; it was impossible for the writer to tell which. There 
were fragments of a much smaller head box, about 0.5 meter 
in length, with nothing in it. At the far end of the cave there 
was a piece of basket work from which the bottom had rotted 
out. This type of basket work resembles the basket work, as 
far as shape is concerned, now found in the Islands. There was 
also a coconut shell with a hole in the bottom; and, curiously 
enough, in the same cave with these rather recent-looking arti- 
facts were two stone implements. ' 
On the west side of the hill and somewhat lower down than 
this cave is a great cavern with one fairly large entrance and 
in the rear a chimneylike opening to the surface. This cave is 
nearly semicircular in shape and resembles the interior of a cathe- 
dral. It is quite gloomy and is inhabited by innumerable 
bats. The floor is fairly level and is covered with bat guano. 
Apparently the deposit of guano in this cave is thick. In 
various parts leading off from the central chamber are some 
tunnels leading deep into the interior of the hill; these were not 
explored. The entrances to these various caves are well con- 
cealed by thick vegetation which has grown up around the lower 
slopes of the hill. The writer regrets exceedingly that the 
views taken of the interior of the caves did not turn out to be 
successful. 
People inhabiting the cave.—The question as to the kind of 
people who lived here is of course open to some conjecture. It is 
certain that no people living on Masbate Island to-day inhabit 
caves; nor do the Filipinos living in Batwaan Valley (there are 
only two houses in the valley) know anything about the former 
dwellers in this interesting place, and with the exception of the 
two Filipino men who accompanied the party to the caves the peo- 
ple strictly avoid the locality. The writer has been in caves in 
northern Luzon where the Igorot people have buried their
