The City of Singapore (City status conferred by Royal Charter on September 22nd, 1951) is famous as an entreport for the export of rubber and tin. Besides this, Communist territoristic activities on the mainland have focused the attention of the world to this island in recent years.

The construction of some of these bridges is different from usual practice, and this description may be of interest. T. Karmakar
