3. Method of Testing. 
Tests were carried out with blocks of wood 5^' x x cut with 
the grain, the relative splitting force of which the fissibility is the 
converse being measured by the number of blows of constant strength 
required to split the blocks completely. The apparatus employed is 
described in section 4 below. Tests were caii'led out by splitting in a
