*The nomenclature here given is slightly different from that of the navy Specifications, but is according to the language of the sea and is therefore used.
In compliance with the request of the editor of the PROCEEDINGS, I submit the following description of the calls and pipes used by the boatswain and his mates in the days of sail and steam.
The call, as we term the instrtiment,1 is divided thus:
Few or no calls issued are shrill enough in sound to suit the men who use them, and each user of a call has his own method of tuning his call to that shrill note required in nearly all the signals used.
Most calls are too open at the pee and have to be flattened or soldered at the sides of the pee, so as to fill the space between it and the bowl.
