Those lumber stacks look like they could be plywood veneer.
Not much plywood production in 1900, that had to wait for better glues. Meanwhile labor was cheap, and even stacks kept the boards from twisting as they dried. This is classic air drying before planing, quite common in Wisconsin, too. Every layer of boards is placed on "stickers" to promote airflow through the stack. You'll also want to note the boards allowed to stick out every dozen or so layers; these provided a stairway of sorts for the guys who worked the top of the stack, both while building it and taking it down later.
