Origin: 1684

When the time comes to set a fire in the fireplace, one of the essential ingredients is the backlog, a large log so called because it is set at the back. Increase Mather mentions it in a dramatic scene from his 1684 book Illustrious Providences: "The spit was carried up the chimney, and came down with the point forward, and stuck in the backlog."

Describing a farmhouse in a snowstorm in the 1770s, Hector St. John de Crèvecoeur mentions "an enormous back-log, without which a fire is supposed to be imperfectly made and to be devoid of heat." A thorough description of a fire properly laid is found in Knickerbocker Magazine for February 1852: "The 'log' has been placed; the 'back-log' has surmounted it; the 'top-stick' crowns the apex; the 'forestick' rests against the 'and-irons'; and the intermediate 'cob-house' of timber, fired by the faithful 'kindling-wood,' is all ablaze, and roaring up the chimney."

As fireplaces and backlogs yielded to central heating towards the end of the nineteenth century, backlog began to blaze in figurative use. At first this new backlog just meant "an accumulation," as in an 1883 Boston article about bicycling: "The roads seemed to improve, and, the back-log of raw eggs and milk beginning to take effect, the pace was improved." Later it acquired its modern meaning "accumulation of work unfinished." From the mid-twentieth century, we have a 1947 Chicago Daily News example: "This is hardly attributable to new-car production, which still counts order back-logs in the millions."
