old seasoned side ; sev- 

 eral knots; failed atone 

 large knot in middle of 

 pillar, which passed 

 through from side to 

 side. "Failure by bend- 

 ing across narrow di- 

 mension. 



3.50 X 4.50 X 45.125 1840 22.6 , Grain straight; one 



old seasoned side; many 

 knots ; failed at one 

 large knot in middle of 

 . pillar, which passed 

 through from side to 

 side. Failure by bend- 

 ing across narrow di- 

 mension. 



3.50 X 4.38 X 4J.5 2170 21.9 Grain straight; one 



old side; many small 

 knots ; one large knot 

 on old side 15 ins. from 

 one end. Failed by 

 crippling at that knot. 



3.73X4.35X44.5 2650 23.6 Straight grain ; fairly 



clear ; some small 

 knots ; one old seasoned 

 side. Failed by bending 

 18 ins. Iron i one end in 

 clear wood across least 

 dimensions. 



3.5 X 4.4 X 45 3346 22.8 Grain straight; two 



old sides ; knot at one 

 end ; also knot at centre 

 passing through a cor- 

 ner. Failed by direct 

 crippling which started 

 at knot in middle of the 

 piece. 



3.5 X 4.4 X 42.5 2082 21.1 Grain nearly straight; 



one old side ; various 

 knots, particularly one 

 near centre passing from 

 cor.ier to corner of sec- 

 tion. Failure by bend- 

 ing at this knot on least 

 dimension. 



3.5 X 4.45 X 46 2243 21.7 Grain straight; one 



old side. Failed near 

 centre by bending across 

 least dimension at a 

 knot, which penetrated 

 the heart of piece from 

 one side. 



3.83 X 383 X 71.3 2862 Two knots on one edge- 



one large knot at centre, 

 another 12 ins. away ; on 

 second face five knots, 

 two near centre, others 

 12 ins. from'ends ; grain 

 parallel ; centre of tree 

 in corner of specimen, 

 failed by bending at cen- 

 tre knot, induced first 

 by being J in. off centre 

 on top bearing.
