HORIZONTAL MOVEMENT OF GEANTICLINES 573 
If we consider Diagram IV, the more general type of defor- 
mation, supposing that the horizontal and the vertical projections 
of the geanticlinal axis have an equal number of bending-points, 
then two different types can be distinguished according as the 
bending-points of the horizontal and vertical’ projections alternate 
or do not (Fig. 6). 
In this figure the combinations p-r, g-s, g-r, and p-s are different 
curves in space to which the originally rectilinear geanticlinal axis 
a has been distorted. The displacement of the geanticlinal axis 
parallel to itself and the distortion of the sections perpendicular to 
the geanticlinal axis are left out of consideration. The bending of 
p and q is much less than that which is shown in the figures. It 
would be more important if a strong compression had been acting 
in the direction of the geanticlinal axis from which would result a 
deformation to transverse folds normal to the geanticlinal axis. 
In this connection it is necessary to consider the geanticline over 
sufficiently long distances to obtain a judgment concerning the 
deformation of the vertical projection of the geanticlinal axis. 
APPLICATION TO THE TRANSVERSE FRACTURES OF THE 
TIMOR-CERAM ROW OF ISLANDS 
If considered over large distances it might seem that the geanti- 
cline, Sumba-Rotti-Timor-Sermata Islands, represents approxi- 
mately TypeI. The uppermo:t elevated reefs are found in Central 
Timor at an altitude of 1,300m.; in West Timor, southeast of 
Kupang, they are at a height of 500 m., on Rotti at 470 m., and on 
Savu at 300m. In East Timor the altitude is estimated at 600 m., 
on the islands farther to the east such reefs are known at altitudes 
of 140 m. on Letti and of 20m. on Lakor, while on Luang no ele- 
vated reefs are found (cf. also Fig. 7). , Thus the part, Sumba- 
Savu-Rotti-West Timor of the geanticline, would represent approxi- 
mately I p-r, and the part, Central and East Timor-islands farther 
to the east, would represent I q-s. 
If considered in detail the deformation is much more compli- 
cated. The deformation of the vertical projection is very slight 
and in many cases it is not exactly known. If the motion of the 
geanticlinal axis parallel to itself be neglected, this projection
