Locobase is a little confused by the Texas Handbook entry and the Gulf Coast Lumberman article cited above. In both, the name Texas Long Leaf Lumber is said to have been given to the former Rock Creek Lumber Company in 1922 in recognition of the diminishing stands of long leaf pine in the Trinity, Texas vicinity. Yet, Baldwin's 1914 spec sheet clearly attributes the sale to Texas Long Leaf.
At any rate, another 1937 article on the Sabine combine's second big mill at New Willard, Tex, indicated that there had been a lot more timber there than they thought in 1922:"New Willard and Trinity are cutting away at opposite ends of what was once one of the greatest forested areas in Texas, and which still holds enough fine pine timber to keep both these mills running for many years to come. Hundreds of private property owners all over this territory who have pine standing on their lands, cut it and bring it to New Willard for sale. This supply is growing steadily. Augmenting their own virgin forests this timber supply stretches far into the future, even for so big a mill as that at New Willard, which cuts about four and one-half million feet of pine monthly."
Locobase doesn't know where the 7 operated, but it was a classic logging Prairie that apparently did not work for any other company before it was retired.
Texas Long Leaf Lumber was bought by Southland Corporation in 1940.
