Looking at the cotton seeds, sisal seeds and cocoa seeds left by Diego Columbus, Marin fell into deep thought. Originally, the adjutant of Diego Columbus should not have been the one who came to report this matter to Marin, but the chief officer was Columbus' assistant for many years. He regarded Columbus as his master, and naturally regarded Diego as his little master. Therefore, after arriving in the local area, the chief officer pretended to be sick and asked Diego to come to report on his work and accept the reward.

Of course, the chief official's contribution could not be eliminated. However, the matter of showing off was given to Diego.

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

Needless to say, Cuba Island was a large island for sugar production in later generations, a world-famous sugar production area, a rum production area, and a cigar production area.

After all, Grenada is too small, with a total of only 344 square kilometers. Moreover, the island has undulating mountains and real plains, and there are not many. If it weren't for the safe environment of poisonous insects, Marin would not have chosen to be a colony.

The Cuba Island is different, reaching 100,000 square kilometers, and most of them are plains. It is the most suitable area for agriculture on the Caribbean Sea.

What's more, in the southwest coastal mountainous areas of Cuba Island, there are nickel ores with huge reserves. If you own nickel ores, Marin can not only make white copper and counterfeit silver coins. It can also be used to make stainless steel, replace white iron sheets, and become the best shell to wrap the hull.

Marin didn't know the specific distribution of Cuba nickel ore, but he knew that there was a city called Moa on the northern coast of southwestern Cuba Island. There was obviously a large nickel ore near the city. Because the two largest nickel ore smelters in Cuba are located in Moa.

Moa's general position is that as the Emperor of History and Emperor of Geography, Marin still remembers it, just a little west of a stubborn peninsula facing northeast. Its latitude is probably a little south at the southernmost end of the Greater Inagua Island.

As long as you find Moa's location, it will be easy to do next. Do you think you can find nickel ore? That's too easy! Because the nickel ore in Cuba is a laterite nickel ore. As long as you find red earth, you can smel it in the furnace and try it. As for the problem of impure purity, it is not a problem. When you find nickel, you can carefully select ore.

So, as long as you find Moa and look for red soil around, the nickel ore will be easily found. In fact, Marin vaguely remembers that the satellite map I saw in my previous life, to the east of Moa City, near a large sea-facing lake, there is a large red area. The red area, when it comes to the laterite nickel ore, Marin feels that 80% of the nickel ore are there.

In fact, Marin was right, it was the largest nickel ore mining site near Moa. As long as you find it, you will find a huge nickel ore.

For this reason, Marin planned to open two colonies in Cuba this time - Havana and Moa. Needless to say, that is a nickel ore, and it is also a treasure in later generations. As long as nickel is obtained, Marin can already imagine a scene where fake silver coins made of white copper are flooding Europe.

Unlike lead-tin alloys, the physical and chemical properties of white copper are very stable. For example, the melting point of the lead-tin alloy solder is too low, only 183 degrees. Just make a red iron block and put the counterfeit coins of the lead-tin alloy up, and it will immediately melt into liquid. Or, make an acid and throw the lead-tin alloy into it, which will easily dissolve.

But white copper is different, and white copper has stable physical and chemical characteristics. No matter whether it is burnt red iron blocks or acid, it cannot be distinguished. Moreover, in this era, people did not know the nickel thing. As long as no one under their own hands revealed their secrets, Europeans would not know the existence of nickel. What's more, Europeans originally mixed a lot of copper into silver coins, and it almost turned into copper coins. This also made it even more difficult to identify the alloys of nickel and copper.

Thinking of the scene where he made a fake silver coins made of white copper and no one could recognize even if they were circulated, Marin smiled obscenely. He could already imagine that in the future, he would use white copper coins to pretend to be silver coins and buy a beautiful scene in Europe...

Cuba laterite nickel ore has reserves of millions of tons. Marin does not need millions of tons, and only 10,000 tons can make white copper coins impact the entire Europe and squeeze the real silver coins market.

In the Moa area, in addition to mining and smelting nickel ore, it is actually possible to engage in some agriculture nearby. Although there are more mountains and fewer plains, no matter what, it is larger than the area of ​​Grenada. You can find fast open space by the nearby river to reclaim a large amount of fields. Don’t have too much, just be self-sufficient.

...

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

Well, the plains on Cuba Island seem to be able to plant anything...

Of course, sugar sugar and cotton, these two are the mainstream trade commodities in the 18th and 19th centuries in the future. Therefore, sugar cane and cotton should become important crops for planting. At the same time, sisal is also important. After all, great sailing is very necessary. In addition to making cables and canvas, fishing nets and rainproof cloths are also important.

The last time I went to Cuba Island, Columbus had found Havana Bay. And, coincidentally, there happened to be a vacuum area of ​​the Tylenol forces, between the two Tylenol tribes controlled areas. Therefore, Marin's subordinates can safely build and reclaim the city here. As long as they gain a foothold, the local Tylenols will not be a concern.

...

As for Panama, the situation is a bit more complicated. Because the climate and environment in Panama are very harsh. Not only are they hot, but they are also humid and rainy. Not only that, there are many poisonous insects and mosquitoes in the local area. When people from other places go, they are easily bitten by poisonous insects and mosquitoes, and then die of evil diseases such as yellow fever.

Therefore, in order to conquer Panama, Marin prepared a long time to prepare a killing weapon - mosquito repellent water...

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! Mosquito-repellent water is to use the dried petals of pyrethra picked in autumn, soak in high-concentration alcohol, and then supplemented with some fragrances to make a low-concentration perfume-floral water.

Because the pyrethroid petals with strong insecticide ability are soaked inside, it contains strong insecticide ability. Not to mention biting mosquitoes, as long as they touch the skin of mosquito repellent dew, smell the pyrethroid (actually pyrethroid), they will become paralyzed and show signs of poisoning. Take a few more mouthfuls of "fairy energy" and you can die directly... Whether it is for mosquitoes or other insects, pyrethroid is a very strong poison. However, for large mammals like humans, this toxicity is minimal. Perhaps only babies will be affected a little. As for adults, it has no effect at all. Moreover, Marin will not send babies to places like Panama where there are poor mountains and bad waters...

When the pyrethra was harvested last fall, Marin sent people to buy a lot of dried pyrethra flowers to make mosquito repellent water. Now, it is time to conquer Panama, which is just in handy.

Marin's instructions to the colonial team who went to Panama were - after arriving in Cologne, Panama (the first colony site planned, as for the name, Marin was too lazy to change, Havana, Moa and Cologne, both adopted the original names), don't rush to advance inland, but first establish a colony site, and then plant all the seeds of pyrethra and mugwort brought. As long as pyrethra and mugwort grow, they will form an isolation belt, so that local mosquitoes dare not approach the colony site at all.

Then, the task of the colonial team was to cut down trees continuously and cut trees in the Pacific Ocean. The ultimate goal was to cut down a road. Moreover, on both sides of the road, pyrethra and mugwort were planted again, making this road a forbidden place for mosquitoes...

Once the road is opened, Marin will consider transporting cement from the local area and making a cement road out to facilitate communication between the Caribbean Sea and the Pacific Ocean. Then, Panama City can be built at the end of the Pacific Ocean.
