Result of the test at Matsubase. — The ground was infested by 
Coptotermes formosanus Shiraki. The experiment station was 
selected in Japan proper as well as in Formosa, in order to 
test the effect under different conditions, especially the effect 
by a different species of termite. The blocks were buried on 
February 11, 1913, and the first inspection was made on Oc- 
tober 8 , 1913, after two hundred forty-nine days. 
Although the duration of the experiment was nearly the 
same at Tainan as at Matsubase, the results obtained were 
slightly different. Thus, in the latter locality, kayil, palo maria, 
and malacmalac were more seriously attacked ; lim, tallow wood, 
iron bark, grey gum, white mahogany, supa, betis, pagatpat, 
calantas, malugay, lanete, bansalaguin, lanutan, banuyo, and 
grey box were less seriously attacked; red narra, guijo, yellow 
narra, white stringy-bark, acle, amuguis, tucang-calao, tindalo, 
batitinan, black butt, clungon, mancono, molave, and ipil, which 
have been attacked by Odontotermes formosanus, were immune. 
These differences seem to be due to the inactivity of the insect 
effected by somewhat lower temperature than in Formosa, as 
well as the existence of a smaller number of individuals. In 
order to get a more satisfactory result, the blocks that were 
found free from attack were buried again in the same place and 
left untouched until July 19, 1915. 
Twenty-one months after first inspection, all the blocks were 
dug out. The results are shown in Table XI.
