The difference between “hallmark” and “trappings”

To abase is to behave in a way so as to belittle or degrade someone.

To abash is to cause someone to feel embarrassed or ashamed.

It might make more sense to pull up a few definitions for these nouns:

Log:

• "1. A rough bulky piece of timber unhewed; a block; a piece of wood." (Lloyd's Encyclopædic dictionary, Vol. 4, 1895, page 626, "lœwigite—loganite")

• "1. A section of the trunk or of a large branch of a felled tree, either in its natural state or cut up for use in building, as firewood, etc." (Webster's New World College Dictionary, as provided by the Associated Press Stylebook Online, 2015-04-14)

Lumber:

• "7. Marketable Timber." (Lloyd's Encyclopædic dictionary, Vol. 4, 1895, page 668, "lumbaginous—lump")

• "2. Timber sawed into beams, planks, boards, etc. of sizes convenient for building or carpentry." (Webster's New World College Dictionary, as provided by the Associated Press Stylebook Online, 2015-04-14)

Timber:

• "Trees cut down, squared, or capable of being squared, into beams, rafters, boards, planks, etc., to be employed in the construction of houses, ships, etc., or in carpentry, joinery, etc." (The American Encyclopædic Dictionary, Vol. 4, 1896, page 4096, "tilly—timber")

• "2. Wood suitable for building houses, ships, etc., whether cut or still in the form of trees." (Webster's New World College Dictionary, as provided by the Associated Press Stylebook Online, 2015-04-14)

So what we can get from these definitions is that timber is the tree or trees that were planted in a grove for the purpose of cutting or found in a forest, which, when cut down, could then further be cut up into various useful pieces of wood that could then be used in building various projects, such as houses or ships.

Lumber is the wood, already cut to any marketable size — from boards meant for flooring, to rafters and beams meant for holding up a structure. If you went to a Home Depot, or another large home-improvement store, you would usually buy the marketable bits of wood here in the lumber department.

Logs are the piece of a felled tree, usually the size of a large branch (could even be a large branch) up to a whole section of a trunk, and generally just a rough piece of wood that you could use either as-is (such as in building a log cabin), for use in small-to-medium projects, or to be used as firewood. Not generally to be found in a finished and marketable form such as a board or plank, which would be lumber. However logs can be marketed and sold as logs, just not as lumber.
