On the sides hung some edible nests of the salangane, but not of the same kind as those found in the caverns on the south coast of Java.

Dr. v. Martens conjectures that the designation salangane comes from langayah, bird, and the Malay prefix sa, and signifies especially the nest as something coming from the bird.("Journal of Ornith.," Jan., 1866.)

The industry of the locality is in collecting Salanganes (edible birds' nests), honey, and wax; but cultivation is not practiced to any great extent.
