The chief special difficulties which timbers used for railroad tics have 

 to face are conditions of alternate moisture and dryness with exposure 

 to the air and the attacks of termites. 



PAYING BLOCKS. 



Really very few woods have been fully tested for paving blocks. It 

 seems undesirable to have woods for this purpose which are too hard, 

 because they will become slippery. It seems undesirable also that the 

 blocks should be very greasy. Several Australian woods which have been 

 tried in Manila have not done well. They have lasted less than two 

 years and were really the poorest of any of the woods tried. The best, 

 very much the best, and most satisfactory wood tried here is Philippine 

 molave (Vitex Uttoralis). On one of the bridges in Manila there are 

 moiarr blocks that are said to have been in constant hard wear for over 

 thirty years and they are still giving very good service. 



The following woods of British India have been recommended for trial 

 as paving blocks: Pynkado (Xylia dolabriformis), saj (Terminalia 

 tomentosa), nagesar (Mesua fcrrea), Lagersiroemia spp., Shorea spp., 

 Hopea sp., Ilardwickia sp., Soymida febnfuga. 



TELEGRAPH AND TELEPHONE POLES. 



Usually the same classes of woods that are suitable for railroad ties 

 will be found to be suitable for this class of work and for fence posts 

 and small bridges or culverts. In the Federated Malay States, chengal 

 is (piite commonly used for this class of work. In Manila, ipil (Intsia 

 bijitga) posts are used to carry electric light and trolley wires. Pdgatpat, 

 tindalo and numerous others are used for telephone poles. 



MINING TIMBER. 



There is usually not very much care exercised in selecting this, but I 

 have known specially good results to be obtained in the Borneo coal mines 

 from the use of leban (Vitex pub esc ens) , kumpas (Koompassia sp.), 

 bUlian (Eusideroxylon zwageri), griting (Lumnitzcra litlorea), and 

 resale (Vatica >[>.).
