Gunpowder and weapons. The chapter introduces us to the captain of "Hispaniola" Smollet. "... The captain was a sullen man. Everything on the ship irritated him. He did not hesitate to explain the reasons for his discontent before us ... - I don’t like this expedition. I don’t like our sailors. I don’t like my assistant ... I was invited , sir, so that I can take the ship to where this gentleman wishes, and did not name the purpose of the voyage, "said the captain." Great, I did not ask anything. But soon I was convinced that the very last sailor knew more about the purpose of the voyage than I. In my opinion, this is ugly. And how do you think? .. “Then,” continued the captain, I found out then we are going to look for treasures ... looking for treasures is a delicate matter. Treasure hunting is not in my part at all, and I don’t feel any attraction to such activities ... speaking frankly, I had to assign the team to me ... Mr. Arrow. .. he is familiar with his sailors. The navigator on the ship should keep away from the sailors ... They say that you have a map of some island. As if crosses on the map indicate places where the treasures are buried. As if this island lies ... And here he with full accuracy called the latitude and longitude of our island ... "
Squier and the boy did not like the captain, but according to his advice, gunpowder and weapons were moved to the room under the master’s cabin, and the owners' cabins and their servants were placed nearby.
