Note 2 — Chapter VII
Reading edition
In our discourse, Yahoo was spoken, but I write it in English because many of my readers would not understand the original. The signals that we used were made by universal code symbols. For example, two flags hoisted representing "P" "D" signified "want (or wants) immediate medical assistance." And so on, by hoists of two, three or four flags representing the consonants, our wants and wishes could be made known, each possessing the key to the code.
Our commercial code of signals is so invented and arranged that no matter what tongues may meet, perhaps those utterly incomprehensible by word of mouth, yet by these signs communications may be carried on with great facility. The whole system is so beautifully simple that a child of ordinary intelligence can understand it. Even the Yahoos were made to comprehend—when not colour-blind. And, lest they should forget their lesson, a gunboat is sent out every year or two, to fire it into them with cannon.
