quartersawn sample plank and end grain sold to me as Western hemlock / Tsuga heterophylla --- check out the really tight growth rings on this piece (over 20/inch) as compared to the sample directly below (about 4/inch) --- looks like this is old growth and the one below is new growth.

both sides of a sample plank of Western Hemlock / Tsuga spp. --- HUGE enlargements are present. This sample was loaned to me by David Clark whom I thank for this and other contributions to the site. The vendor of this sample, who is VERY unreliable about figure designations, has this as "bird's eye" figure, which is just silly. It DOES have some indented grain (see the end grain update below) and a few circular marks here and there but that does NOT make it bird's eye. The labeled side is raw but the other side is sanded down to 240 grit and shows as much cleaner and does not have the slight patina (and some dirt) that the labeled side has.

END GRAIN UPDATE from directly above. I see that I got this upside down, but more interestingly, you can see by comparing this to the end grain closeup directly above that this very slight amount of sanding that happened between the two made a significant difference in the indented grain section, indicating that it does not persist very long the way it does in, for example, bear claw Ponderosa pine, but rather causes slight circular or oval marks, exactly like what you see on the flat cut surface of this piece.

the second face, before and after sanding, showing how the patina from aging is only surface deep.

Too late now, the sample has already gone back to David.

END GRAIN UPDATE from directly above --- I did the update from the other end because I didn't want to risk a resin leak from that knot when the upgrade sanding process made the wood hot, which it does.

The three pieces of wood in this section are from 3 different reclaimed barn planks and were sent to me for ID. Based on the lack of resin canals, the look of the wood, characteristics of the earlywood/latewood, the density, I am confident that these are hemlock and almost certainly Eastern hemlock. The fact that the barn was in Michigan adds to my belief that these are Eastern hemlock and not Western. Mark Peet took a look at them and almost immediately declared them to be Eastern hemlock (with no prompting from me).
