failure is shown in the second figure (fig. 2). Another similar 
block of insignis, 23 in. x 32 in. in area, treated in the 
same way, gave a maximum load of 1,460 lbs. This also failed 
in compression. The average maximum pressure exerted by 
the two blocks was 139 lbs. per sq. in. A block of Pinus 
canariensis was dealt with in the same way, and for three days
