value than the original would warrant. Especially is this true 
since the later statements carry with them the weight of scien- 
tific authority. In this case, as in the preceding ones which 
have been discussed, there is no testimony from an eye witness, 
and the statements made contain no internal evidence that they 
are based on the observation of phenomena of volcanic eruptions. 
Moreover, the examination of the island has not yet brought 
to light any evidence of volcanic activity during historic time. 
The geologic formations of Timor in so far as they are known 
consist of igneous and metamorphic rocks, with younger Paleo- 
zoic, Triassic, Jurassic, and younger Tertiary sedimentaries. 
The younger Paleozoics and Triassic formations have been 
broken by igneous rocks, but the Jurassic and younger Tertiary 
have not been seen to be so, or to show contact metamorphism. 
Timor has not been well mapped, but it has been sufficiently 
explored so that recent volcanic phenomena would not have 
passed unnoticed. Evidently it should not be included in the 
list of voleanic islands. The “Java line” which has been traced 
into Timor by some authorities passes to the north of Timor 
and terminates in a hook-like curve which extends through the 
Damar Islands to the Banda group. Timor belongs in an outer 
curved line which swings around through Timor Laut, the 
Lesser Kei Islands, Ceram, and Buru which, in so far as known, 
have similar geologic formations and do not contain volcanoes.
