Ghost Light Monday--the funniest thing I've read in a while

Fans of obvious double entrendres prick up your ears! This article from the recent issue of The Tracker (a quarterly on historic organs--you know the musical instrument) is the funniest thing I've read in weeks. I'm not certain if its an April Fool's joke or the real deal. It helps if you know that pipe organs are essentially wind instruments with high-pressure air chambers that force air through their pipes in order to make sound. A footnote to the article says it is reprinted from Everybody's Guide to Music from 1894 and was written by Josiah Booth. The headline gives a strong hint of the text to follow:

Directions for Blowing the Organ

Although the blowing of the instrument does not devolve upon the player, it is important that he should have a full knowledge of this department to start with. More harm can be done to the organ by bad blowing than by bad playing, therefore see that this duty is always properly performed, according to the following directions:

The bellows' handle should be firmly grasped near the outer end, and then moved up and down with a slow, sweeping stroke, which must be absolutely free from all jerking. An indicator usually shows the amount of wind contained in the reservoir, and this should be kept as nearly as possible in the position shown in the illustration.

With a soft organ a very slow stroke will suffice to keep in the wind; a loud organ will require a quicker and stronger stroke; in all cases, the indicator must be made to ride steadily in one place. Wind must on no account be blown when the indicator is at full, as this causes a straining of the wind-chest, and gives annoyance to the player by the noise of superfluous wind rushing from the escape-valve.
