In fact, cryolite is mineralized in nature, but very rarely. Moreover, it seems that cryolite deposits are mainly in Greenland, which is within the Arctic Circle.

But there are very few cryolites in nature, and there is simply not enough. Therefore, later generations artificially synthesized cryolite for use in the electrolytic aluminum industry. But this specialization is too strong, at least, Marin, a liberal arts student, doesn't understand. Greenland was so big that he couldn't possibly know where the cryolite mine was. The most important thing is that he doesn't know what cryolite looks like......

Therefore, he knew that the islands of Haiti and Jamaica were rich in bauxite resources, but he did not have the means to develop them. A cryolite, you can make him kneel. Otherwise, you can get some aluminum alloy armor, so many bunkers?

But in the absence of cryolite, Marin had only one way to use that bauxite – to make refractory bricks for use in smelting furnaces for steel and non-ferrous metals......

But now the demand for metal is very low, there are few iron-smelting furnaces and metallurgical furnaces, and the need for refractory bricks is also limited. Therefore, the bauxite in Europe is sufficient, and there is no need to import bauxite from the Caribbean at all.

But gold, silver, copper and nickel ore are still very important. Gold and silver are not spoken, but they can be used as money. And the price of copper is also very expensive at the moment, and there seems to be no famous copper mines on the island of Haiti, so it is better not to develop them. However, nickel ore seems to be easier to develop, because the nickel ore in Dominica is also laterite nickel ore. When the time comes, as long as you observe the color and study the laterite when you see it, you will be able to find nickel ore.

Because of the development of the island of Haiti, Marin sent people to find people who had been to the island of Haiti. Coincidentally, a student named McCass in Columbus was entrusted by Columbus to travel to Santo Domingo on the island of Haiti last year to visit the place where Columbus made his birth.

Hearing that Captain McCasse had been to Santo Domingo last year, Marin immediately called him over to find out what was going on......

McCasse was in his thirties, in the prime of life, and he was one of Columbus's proud disciples. Last year, McCasse was ordered to transport nickel to the island of Cuba, and was commissioned by Columbus to visit the place where the teacher had fought.

Knowing that Marin was interested there, McCasse carefully briefed Santo Domingo on the situation......

Santo Domingo, the first colonial city established by the Spanish colonists in the Americas, has been abandoned for more than a decade. The castle, once tall and fortified, is now almost in ruins.

The main structures such as the walls of the castle are fine, but the wooden structures in the castle have been demolished by the locals......

Including the main gate, there are all kinds of wooden furniture, and even the windows and walls, all of which have been dismantled by the locals and used as wood. McCas saw with his own eyes that the houses in the indigenous villages near Santo Domingo had a lot of wood used by the Spanish colonists in the castle......

You ask McCass why he can tell where the wood comes from? Quite simply, there is paint on those woods!

The indigenous people of Haiti do not know how to use paint, and only in the castles built by the Spanish colonists, there will be paint. So, the wood with different colors of paint must have been removed from the castle by the local natives.

As for why the local natives don't live in the castle? Because the castle is too far away from their village......

These indigenous peoples make their living mainly by growing cassava and sweet potatoes, and naturally live as close to their farmland as possible. The castle is too close to the sea and a bit far from their farmland. Therefore, the local natives did live in the castle for a while after the Spanish withdrew. But then I found that it was inconvenient to work in the fields, and it was too far, so I moved back to the village. Before leaving, they removed all the wood they could......

McCasse estimated that it would be easy to restore Santo Domingo as long as there was enough wood. After all, such a main structure as a stone wall was not damaged.

Moreover, he also told Marin the news that stunned Marin - the mountains and forests near Santo Domingo are full of horses, cows, sheep and pigs left behind by the Spanish colonizers......

It's just that more than ten years after the Spaniards left, these horses, cows, sheep and pigs have been reduced to wild animals and roamed in the mountains and forests. Moreover, it has fallen prey to the natives.

Among them, the best "mixed" is the pig. Relying on their strong reproductive ability, their populations have expanded rapidly, and they have become local tyrants. Now, they are no longer domestic pigs, but wild boars.

The breed of domestic pigs brought by the Spaniards is actually relatively close to wild boars. They are smaller in size and grow slowly. Moreover, only a few are born in one child.

Even so, the strong reproductive ability of giving birth to several children in one litter has also crushed horses, cattle and sheep. Therefore, now in the mountains and forests near Santo Domingo, there are the most such "wild boars".

This kind of wild pig, the locals don't dare to mess with it. Because, the wild boar went crazy, and ordinary people couldn't stop it. Although he has no fangs, he can charge up and kill people. In particular, wild boars also like to be in packs......

Then, the horses and cows mixed up okay. The horses left behind by the Spaniards were Andalusian horses, which were fast and fast despite their low fertility rate. When the local aborigines went into the mountains to hunt, the horses had already run away when they heard the wind, so it was safe.

And the cattle, the cattle brought by the Spaniards were longhorns. This is a type of cattle that Columbus brought from coastal Spain, with long horns but very tame. The later famous Texas longhorn cattle are descendants of this longhorn cow.

In fact, this kind of cow is very timid and does not have a fierce temperament. But when the local natives saw such a long horn, they were a little weak and didn't dare to provoke ......

Therefore, the only ones who are unlucky are the sheep......

Because it is a tropical rainforest, the sheep brought by the Spanish colonists are not the famous merino sheep, but some unknown breed of goats along the coast. After all, goats are better adapted to the climate of rainforest regions than sheep, which have a thick wool.

The local natives did not dare to provoke wild boars, horses, or longhorns, so they could only attack these tame sheep. Therefore, the Spanish goats, which fled to the wild and became wild sheep, became the best prey for the local natives.

According to what McCasses and his team of sailors saw, it was estimated that there were at least a few hundred horses, thousands of longhorn cattle, thousands of wild domestic pigs, and hundreds of goats in the mountains near the local village......

Yes, the goats are the least, mainly because they are hunted more by the locals, after all, they are easy to bully......

Well, it seems that after the reoccupation of Santo Domingo, there is no need to look for livestock, just send troops to the nearby mountains and forests to catch them.

Horses and cattle are easy to say, as long as you use the legendary lasso. The goats are directly surrounded and caught, and only the wild domestic pigs are a bit troublesome.

Eventually, Marin made up his mind - to deal with it with a trap. Those who can be domesticated are domesticated, and those who cannot be domesticated again are directly killed with muskets, just eating pork......
