Spring near Alor Gajah. 



Part of this spring has been collected in a tank inside a 

 little house, part of it rises in the bed of a little brook close 

 to this house, and a third outlet has been set and received in 

 a square bricked trough or well. The latter evidently (from 

 its temperature, etc.) corresponds to the main feeder.
