Penang Botanic Garden arch leans further

Who needs the Leaning Tower of Pisa when we have the Leaning Arch of Penang!

To find out once and for all whether one of the two arches there is really leaning, ’someone’ set up two plumb lines last night at the arch.
He found that not only is the arch tilting dangerously, it has worsened since the use of the theodolite in early May. It was then five inches off the vertical, but is now 15 inches.
The upright stick corresponds to where the string starts at the top of the arch. The lead plumb that you can see (metal upside down pyramid thing) should be where the stick should be IF it is perfectly vertical. You can see that the plumb is way off, by about 15 inches.
It also looks like its tilting both along the major as well as the minor axes, assuming the two arches were perfectly aligned to start off with.
Thanks to this mysterious ’someone’ for this expose and the public service rendered.
