Ever since the FCC dropped the higher-speed code requirements, some of the nicer touches of operating procedures for CW have become a bit more difficult to pick up.
Of course, they were never that simple to come by. Bad habits tend to sprawl. Back when John Huntoon edited QST, he printed an article by W6DTY* that summarizes good operating without being stuffy or too preachy. It went over well enough that ARRL reprinted it as a handout and sent it to new hams; and now, YOUR NOVICE ACCENT And What To Do About It is available as a PDF, thanks to N4MW.
If you're still working on learning the code, Mr. Huntoon addressed that himself, in 1941: This Business Of Code is still excellent advice.
(Interestingly, I find 4 hams of that name current at QRZ.com, one of them in East Hartford, CT. The former QST editor was a teenager in the late 1930s.)
A side note, there's a website devoted to radio work on the Great Lakes and major rivers -- fascinating! Yes, even paddlewheel steamers had their "Sparks" once radio came along.
* Keith Williams, then. The callsign is presently held by, as FCC puts it, "a close relative of the former holder." This mode of remembrance is one of the Commission's more graceful accommodations.
