|Abstract||To improve the East Indian leather industry a search was made for tan barks and other tanning products, and their suitability and productivity per ha were assessed. At first (1917-1924) the study concentrated on tanning products already locally used, including those from mangrove forest, but considered also some promising local and exotic (some well known) products. For all species considered botanical data, geographic distribution and, where possible, information on bark production and quality, and on culture of the trees were discussed.
Other topics were trade in leather and tanning substances in the Netherlands East Indies, trade in mangrove bark and catch and tanned hides in the Malayan Straits Settlements, leather dressing and working in the Netherlands East Indies, research on tanning substances, experiments on practical tanning and on methods of collecting bark. Finally followed the main conclusions for supply of tanning substances for the home industry. An appendix included a key to the tree species of mangrove forest.
