The chief special difficulties which timbers used for railroad ties have 
to face are conditions of alternate moisture and dryness with exposure 
to the air and the attacks of termites. 
PAVING BLOCKS. 
Realty 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 littoralis) . On one of the bridges in Manila there are 
molave 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 ferrea), Lagerstroemia spp., Shorea, spp., 
Hopea sp., Hardwickia sp., Soymida febrifuga. 
TELEGRAPPI 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 quite commonty used for this class of work. In Manila, ipil ( Intsia 
bijuga ) posts are used to carry electric light and trolley wires. Pagatpat, 
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 pubescens) , kumpas ( Koompassia sp.), 
billian ( Eusideroxylon zwageri ), griting ( Lumnitzera littorea) , and 
resak ( Vatic a sp.) .
