The following are the results of the tests for wetness and transverse 
strength ;— 
Wetness Tests.—The bars for the transverse tests were prepared in 
December, and stored in a dry place till the middle of January. Hence, 
when tested, they were sensibly drier than the timber when received, 
After the transverse tests were made, drillings were taken from each bar 
and weighed, before and after drying, for about twelve hours in an oven 
at about 180° F.
