Chapter 1776: The king who collected the dung

Marinko no matter what the Genoa people think, he just explained the truth:

"My teacher once traveled to Port Kaffa and talked with the local elders, only to find out the truth of the year. However, while traveling to Asia, the teacher discovered a very strange phenomenon-although the local Black Death also broke out Record, but it is not as frequent as ours. Then, he conducted investigations in Persia and Turkey for more than ten years, and finally found the secret ... "

"What secret?" Everyone raised their ears curiously. Because black death is more terrible than smallpox, and it is very important to avoid black death.

"The teacher found that women in the Middle East are not allowed to go out because they are trapped in their homes. Therefore, many women like to keep cats to accompany themselves. And these cats are not only the mistresses of the hostess, but also the killers of mice. The rats in the Middle Eastern family have been wiped out ... "

"A cat ... But isn't a cat an unknown incarnation?" Emperor Maximilian I wondered.

"The problem is here ..." Marin gave the emperor a compliment in his heart-a great compliment!

Marin explained:

"The teacher found that the reason why cats are considered unknown is because in the spring night, cats make a terrifying and annoying cry when courting. On a quiet night, this kind of cry is really chilling, like a devil. But in fact, it ’s just those cats who want to find a heterosexual breed ... "

Speaking of this, many of the people present laughed ... This kind of topic, men have been excited since ancient times ...

Marin waved his hand:

"Don't laugh, tell you the truth! This kind of cry is actually a normal courtship confession from a cat, similar to the human saying" Girl I love you "..."

Everyone's laughter is bigger, this topic is a little exciting ...

"It's just that the sound of a cat's courtship sounds a little scary, and it's really silent at night, so it is misunderstood as a demon. But everyone knows that cats are active in the middle of the night, there is no way. And dogs It ’s a pet, but because of the activities during the day, although there are also calls, it does not affect people ’s lives. In the final analysis, the midnight calls of cats are a bit outdated. And, it ’s a bit ugly ... "

"But, Grand Duke Marin ... oh no, Your Majesty Marin, what does this have to do with the Black Death?" Asked French envoy Dolby.

Marin glanced at Dolby and explained:

"I just said that the Black Death is called plague, which is spread by fleas on mice. If there are enough cats to eat the mice, is there no way to spread the Black Death?"

After listening to Dolby, nodded and said:

"It seems to make sense ... But can you prove it?"

Marin shook his head and said:

"I can't prove it because it's too dangerous. After all, black death is different from smallpox. Smallpox grows vaccinia, so it's not afraid of smallpox. However, after the black dead patient survives, the next time he encounters black death, it is still dangerous. Therefore , I do n’t dare to prove it. "

Then, Marin said:

"But what I want to tell you is that the Beihai Kingdom has been raising cats for a long time. Every grain store in the Beihai country will keep some cats to deal specifically with rats stealing food. Therefore, our grain store has less food loss. Moreover, the elimination of rats also helps to curb the spread of the Black Death. "

"Everyone knows how dirty the bilge on the merchant ship is. On many merchant ships, there are a lot of rats in the bottom bin. The Genoa merchant ship that came back from Kafa was brought back because of the mice, which led to the black death. The spread of the disease. "

"Actually, the Black Death can be so harmful in Europe, because we misunderstood cats before, expelled or even killed the cats. As a result, the proliferation of mice became the disaster, and the spread of the Black Death was even more rampant. So. Only in Europe will tens of millions of people die because of the Black Death ... "

"And the teacher's notes stated that in some cities with a lot of cats, the Black Death never broke out unless it came from outside. The reason why Europe could not stop the Black Death was because the cat was expelled. It ’s only when rats are rampant that the Black Death spreads so quickly. "

"So, in order to prevent those commercial ships from bringing back plague from the outside world, I have ordered every commercial ship sailing overseas to have a cat, specially used to deal with the rats on the ship, to avoid the recurrence of the black death. No rats , The Black Death has no source of spread. "

"Of course, raising cats to kill rats is just the first step. In addition to eliminating rats, teachers also advocate hygiene in their notes. For example, the feces in the city need to be cleaned up and transported out of the city to avoid the breeding of flies. Teacher The records say that not only are mice prone to breeding problems, but also flies that are parasitic on feces everywhere in the city are also likely to cause plague ... "

"So you made the city of Beihai clean and the feces were collected and shipped out of the city?" Maximilian I stood up in time.

Marin nodded and said:

"Yes, that's it. The flies grew out of maggots parasitic on the feces. Their claws are filled with unclean things like feces. If the flies sting the feces everywhere in the city, go and bite you White bread ... "

Speaking of this, many people probably think of something, and their faces are hard to look ... because, it is really very likely ...

Marin, regardless of their nausea or nausea, continued:

"If the flies sting something that has plague, then bite the food you eat, eat this food, it is easy to get sick and even cause a plague ..."

Many people have changed their complexion, and it is "cry" Maximilian I, he hesitated:

"It's not that we don't want to do this, but that if we also start collecting feces, this labor cost is very high! If we take care of the city cleanly, God knows how much it will cost ..."

For the famous poor ghost emperor, money is the biggest problem ...

Marin really wanted to tell them that manure can be pulled out as fertilizer, just like the Ming Dynasty. However, this is to cultivate competitors and easily cause food prices to collapse. How can Marin make a fortune on this basis?

But he thought of a way:

"Don't you all know that excrement is accumulated in the septic tank, can you collect nitrate and use it to extract saltpetre? Just build a nitrate collection center outside each city and dig out multiple square pits for collection Nitrate. The price of saltpetre is known to everyone, and there is also a shortage. Only by this, the labor cost required to collect manure in the city can be recovered ... "

"This is a good way ..." The emperor nodded, but asked again:

"Nitrite frost, generally when the weather is relatively cold, how to collect nitrite in warm weather such as summer and late spring and early autumn?"

At this time, the method of collecting soil nitrate is still very backward. I only know that when the weather is cold, the frosted nitrate in the corner of the pit is collected and scraped down to extract it.

But they do n’t know that it is not so troublesome to collect soil nitrate in later generations, and directly mix the soil with urine to react naturally. Then, directly refine. In this way, the proportion of saltpeter is also higher. On the other hand, the ratio of frosted nitrite on the wall is actually relatively low, and only part of the nitrate can be calculated.

But Marin will not tell them the complete extraction method of soil nitrate, so he gave a suggestion:

"Well, if you have a city close to the Rhine, if you ca n’t extract nitrate in summer, late spring and early autumn, just barrel it and ship it to the North Sea country by boat, I will buy it! In this way, you do n’t have to worry about the warm weather It ’s impossible to recover the labor cost of collecting feces! "

Marin has long coveted the huge amount of feces in various countries. Unfortunately, he could not find a reason to buy it before. Moreover, it is easy to cause suspicion in other countries. But now he found a reason ...

"Do you have a way to collect soil and nitrate when it is hot?" "Clerk" Maximilian I asked doubtfully.

Marin had countermeasures, so he answered with confidence:

"Yes, I have bought Iceland from Denmark, where it is cold all year round, but it is not cold enough to freeze. It is the best climate for collecting soil and nitrate. As long as the feces are shipped to Iceland for accumulation, it will definitely be able to A lot of soil was scraped out. Moreover, there are few people in Iceland, and they are not afraid that the island is too dirty to be filled with feces. In addition, the place is a bit cold and flies are difficult to survive ... "

Everyone heard it and it made sense. After all, everyone in Iceland has heard that it is Iceland, but only inland is relatively cold, and the coast is still not icy. This temperature is probably equivalent to the climate of frost in the middle of the late autumn, and it is the most suitable for seeping soil. It is indeed very good.

But they didn't even know that Marin actually wanted to trick the fertilizers of various countries by this means. After all, the fertility of manure is the most valued by Marlin compared to that point of soil frost.

Moreover, now Marin has no ability to engage in ammonia synthesis. If he wants enough nitrogen fertilizer, he can only cheat the feces of other countries ...

The Icelandic climate is used to collect the lie of the earth frost end ~ www.wuxiaspot.com ~ It also seems to have no loopholes, very reasonable, so reasonable that no one doubts it. Moreover, Beihai also really needs saltpeter. After all, the proportion of firearms in the North Sea army is very high.

So, while introducing the causes and prevention methods of the Black Death, Marin, the newly-emerging king, even talked about the business of collecting feces with the monarchs and envoys present ...

Marin repeatedly emphasized:

"Be sure to bring wet feces with urine, not dry feces!" The reason why it is so emphasized is that most of the cost of nitrite is generated from urine, not from feces. He was afraid that the countries selling manure were too real, and sold it to him.

To this end, Marin also offered to provide sealed manure buckets for them to hold wet stools ...

As for the purchase price, it is almost the labor required by those cities to collect feces. The labor cost in Germany is only 2 Finney per day, so there is really no need to pay much.

Those monarchs and great aristocrats do n’t care about this money, as long as they do n’t have to pay the wages of workers who collect feces by themselves.

In this way, a good scientific lecture on how to deal with the black death disease was stunned by Malin, a frivolous second-hand goods, and became a conference site for collecting feces ...

"The king collects big dung", Marin is famous. This terrier was later used by Europeans for hundreds of years ...
