Compression perpendicular to grain: One specimen from each of 50 per cent of the static bending sticks. These will be marked "2" in addition to the number of the stick from which they are cut.
Hardness: One specimen from each of the other 50 per cent of the static bending sticks. These specimens will be marked "4."
Shear: Six specimens from sticks not tested in bending or from the ends cut off in preparing the bending specimens. Two specimens will be taken from near the pith; two from near the periphery; and two that are representative of the average growth. One of each two will be tested in radial shear and the other in tangential shear. These specimens will have the mark "3."
Cleavage: Six specimens chosen and divided just as those for shearing. These specimens will have the mark "5." (For sketches showing radial and tangential cleavage, [see Fig. 45].)
When it is impossible to secure clear specimens for all of the above tests, tests will have precedence in the order in which they are named.
Tests to Determine the Effect of Air-drying
These tests will be made on material from the adjacent bolts mentioned in "c" under Part of Tree to be Tested. Both bolts will be cut as outlined above. One-half the sticks from each bolt will be tested green, the other half will be air-dried and tested. The division of green and air-dry will be according to the following scheme:
| STICK NUMBERS | |||||||||||||
| Lower bolt, | 1, | 4, | 5, | 8, | 9, | etc. | } | Tested green | |||||
| Upper bolt, | 2, | 3, | 6, | 7, | 10, | ||||||||
| Lower bolt, | 2, | 3, | 6, | 7, | 10, | etc. | } | Air-dried and tested | |||||
| Upper bolt, | 1, | 4, | 5, | 8, | 9, | ||||||||
All green sticks from these two bolts will be tested as if they were from the same bolt and according to the plan previously outlined for green material from single bolts. The tests on the air-dried material will be the same as on the green except for the difference of seasoning.
