Hehe. Sorry, all that is WELL documented. Check the 1859 New York SLIMES editorials. I cannot BELIEVE what warhawks they were!
Then you won't have any trouble pointing to those editorials, then. Here's a link to their search. I've narrowed it down to the 14,000 articles indexed from 1859 to help you.
Charles Adams did claim to find a bellicose Times editorial in early 1861, after the paper had been advocating simply letting the South go, but the article I found doesn't match his description: it's not about imports flooding the North from New Orleans, but about Northern goods flooding the South in the other direction.
It's not especially war-like either. It just points out that if the Confederate government wanted to impose a tariff on Northern goods it would have to build custom houses along the border and risk alienating citizens who expected to be able to buy Northern manufacturing goods without red tape.
Apparently, Charles Adams, like DiLorenzo and a lot of you clowns, goes all Pavlovian when ever he sees the word "tariff." He starts salivating and slabbering and his mind stops working.
Anyway, all the evidence I've seen so far shows that the Times wasn't beating a steady drum for war in 1861, let alone in 1859.
