Mr. McCullagh, in a letter to one of the editors of this Dictionary, says: “I cannot explain how I came to use it, except that, while on the gunboats on the Mississippi river during the war, I used to hear the pilots say of the river, when rising rapidly and overflowing its banks, that it (the river) was ‘booming.’ The idea I wished to convey was that the Grant movement was rising—swelling, etc. The word seemed to be a good one to the ear, and I kept it up. It was generally adopted about a year afterward. I used it as a noun after a while, and spoke of ‘the Grant boom.’ ”]
