Looking at Diego. The cotton seeds, sisal seeds, and cocoa seeds that Columbus left behind, Marin fell into deep thought. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 infoOriginally, it shouldn't have been Diego to report this to Marin. Columbus, the adjutant, came, but the chief officer was originally Columbus's assistant for many years, and he regarded Columbus as the master, and naturally regarded Diego as the little master. Therefore, after arriving in the homeland, the chief officer pretended to be sick and asked Diego to report to work and accept the reward.

Of course, the credit of the chief officer cannot be escaped. It's just that the limelight was given to Diego.

Marin suddenly felt that it was time to develop Cuba and Panama......

Needless to say, Cuba was a large sugar producing island in later generations, a world-famous sugar producer, a rum producer, and a cigar producer.

After all, the island of Grenada is still too small, with a total of 344 square kilometers. Moreover, the island is mountainous and undulating, real plains, and there are not many at all. If it weren't for the safety of poisonous insects, Marlin wouldn't have chosen this place as a colony.

The island of Cuba, on the other hand, is 100,000 square kilometers and mostly plain, making it the most agriculturally suitable area in the Caribbean.

What's more, in the mountainous area on the southwest coast of the island of Cuba, there are huge reserves of nickel ore. If he had nickel ore, Marlin would not only be able to make white copper but also counterfeit silver coins. Moreover, it can also be used to make stainless steel, replacing white iron sheets, making it the best hull to wrap around the hull.

Marin did not know the exact distribution of nickel mines in Cuba, but he knew that there was a city called Moa on the northern coast of the southwest of the island of Cuba. In the vicinity of the city, there is obviously a large nickel mine. This is because the two largest nickel smelters in Cuba are located in Moa.

The general location of Moa, as the Emperor of History and the Emperor of Geography, still remembers, is a little west of a stubby peninsula facing northeast. Its latitude is about a little further south at the southernmost tip of Great Inagua.

As long as you find Moa's location, the rest is easy. Looking for nickel ore, you say? That's so easy! Because, the nickel ore in Cuba is laterite nickel ore. As long as you find red clay, you can take it to the furnace and smelt it. As for the question of impurity, it is not a problem. Wait until nickel is found, and then fine beneficiation.

So, as long as you find Moa, and then look around for red soil, nickel ore will be easily found. In fact, Marin vaguely remembered that the satellite map he had seen in his previous life showed that there was a large red area to the east of the city of Moa, near a large lake near the sea. The red area, associated with laterite nickel ore, Marin thinks, nickel ore eight achievements are there.

In fact, Marin was right, it was the largest nickel mining site near Moa, and if you found it, you would find a huge nickel mine.

To this end, Marín intends to open two colonies in Cuba - Havana and Moa. Needless to say, Moa is a nickel ore, and it will be a treasure in the future. As soon as nickel was obtained, Marin could already imagine counterfeit silver coins made of cupronickel flooding Europe.

Unlike lead-tin alloys, cupronickel is very stable in terms of physical and chemical properties. For example, the melting point of lead-tin alloy solder is too low, only 183 degrees. Just get a piece of red-hot iron and put a counterfeit copy of lead-tin alloy on it, and it will melt into liquid in no time. Or, if you make an acid and throw the lead-tin alloy into it, it will also be easy to dissolve.

But cupronickel is different, and the physical and chemical characteristics of cupronickel are stable. Whether it is with red-hot iron or acid, it is impossible to distinguish. Besides, in this era, the world still doesn't know about nickel. As long as no one of their subordinates divulges secrets, Europeans will not know about the existence of nickel. What's more, the Europeans had already mixed a lot of copper into silver coins, and they were about to become copper coins. This also leads to an alloy of nickel and copper that is more difficult to identify.

Marin smiled obscenely at the thought of the fact that he had made a counterfeit silver coin made of white copper, and no one could recognize it even if it was circulated. He can already imagine the future of a beautiful scene in which a copper coin will be used to pass off as a silver coin and buy all of Europe......

Cuban laterite nickel ore with reserves of several million tons. Marin doesn't need to beat 10,000 tons, as long as 10,000 tons, he can make the copper coin hit the whole of Europe and squeeze the real silver coin market.

In addition to mining and smelting nickel ore in the Moa area, there is actually a little agriculture nearby. Although there are many mountains and few plains, it is larger than the island of Grenada. If you look for a quick vacant land near the river, you can reclaim a lot of fields. Don't have more, just be self-sufficient.

……

As for Havana, it is located in the western plains, which is the most suitable for agricultural development. Here, Marin can grow sugar cane, rice can be grown, cotton can be grown, sisal can be grown, cocoa can be grown, large areas of spices and rubber trees can be grown......

Well, the plains of the island of Cuba seem to be able to grow anything......

Of course, sugar and cotton were the mainstream trade commodities of the 18th and 19th centuries. Therefore, sugarcane and cotton should be important crops. At the same time, sisal is also important. After all, the Great Voyage is very needed, and in addition to making ropes and canvas, it is also important to make fishing nets and rainproof cloths.

Last time I went to the island of Cuba, Columbus had already found the Bay of Havana. And, coincidentally, there is a vacuum of Taíno power, between two Taíno tribal controlled areas. Therefore, Marin's subordinates can build and reclaim the city here with peace of mind. As long as they have a foothold, the local Taíno people have nothing to worry about.

……

On the Panamanian side, the situation is a bit more complicated. Because, on the Panamanian side, the climate and environment are very harsh. Not only is it very hot, but it is also humid and rainy. That's not all, there are still a lot of poisonous insects and mosquitoes in the local area. Outsiders are easily bitten by poisonous insects and mosquitoes, and then contracted yellow fever and other vicious diseases and die.

Therefore, in order to conquer Panama, Marin has been preparing for a long time, and has also prepared a big killer - mosquito repellent toilet water......

Mosquito repellent flower water is made of sun-dried petals of pyrethrum picked in autumn, soaked in high-concentration alcohol, and then supplemented with some flavors to make low-concentration perfume - flower water.

Because the inside is soaked with insecticidal chrysanthemum petals, it contains strong insecticidal power. Mosquitoes bite people, as long as they just touch the skin that has been smeared with mosquito repellent toilet water and smell the smell of pyrethrum (in fact, pyrethroid), they will be paralyzed and show signs of poisoning. If you take two more breaths of "immortal qi", you can die directly...... Whether it is against mosquitoes or other insects, pyrethroids are very poisonous. However, for a large mammal like humans, this toxicity is minimal, and presumably, only babies are affected a little. As for adults, it doesn't matter at all. And Marin wouldn't send a baby to a poor place like Panama......

When pyrethrum was harvested last fall, Marin sent people to buy a lot of dried pyrethrum flowers to make mosquito repellent toilet water. Now, it's time to conquer Panama, which comes in handy.

Marin's instructions to the colony team going to Panama were to go to Colón, Panama (the first colony planned, as for the name, Marin didn't bother to change it, Havana, Moa, and Cologne, all of which used their original names), not to rush inland, but to establish a colony first, and then plant all the seeds of pyrethrum and wormwood that he had brought with him. As long as pyrethrum and wormwood grow, they form a barrier that prevents local mosquitoes from approaching the colony.

Then, next, the task of the colony team is to keep cutting down trees, in the direction of the Pacific Ocean. The ultimate goal is to cut down a road to get out. In addition, on both sides of the road, pyrethrum and wormwood were planted again, making the road a mosquito no-go......

Once the road is opened, Marin will consider transporting cement from the mainland to make a concrete road out to facilitate communication between the Caribbean and the Pacific Ocean. Then, on the Pacific side, you can build Panama City.

With Panama City, Marin was able to build several clippers to be placed in Panama City. Then, starting from Panama City, through the Pacific Ocean, to find the route of the Ming Dynasty, and finally, to complete the exchange and trade with the Ming Dynasty......
