Chapter 130: set sail

Because of time constraints, Da Gama is about to start, so Marin also plans to speed up the process and start early.
In fact, Marin got some data from the West African coast from the Portuguese. For example, there is a large freshwater estuary where fresh water can be replenished.
You know, in this era, the preservation of fresh water is very troublesome. Generally, a bucket of fresh water starts to odor within a few days, making people unable to drink. To combat the problem of freshwater odor, later navigators invented a way to carry spirits such as rum. Because, hard liquor is not bad.
However, after the invention of citric acid, freshwater preservation has been greatly developed. In general, fresh water with citric acid takes a long time to deteriorate. As for the method of dripping lemon juice, fresh lemons cannot be stored for a long time ...
It's okay to soak lemon leaves, but it doesn't take long. Because the lemon leaves have a lower citric acid content.
For this reason, Marin thought about it and thought of how to handle cans ...
The earliest canning was actually putting canned materials into glass cans and corks. Then, put the canned bottle in a steamer and heat it to kill all the bacteria in the canned bottle. In this way, canned food can be stored for more than 10 months. Of course, in order not to leak air, wax around the cork.
Marin designed a large pot for the fleet to heat freshwater wooden barrels. Freshwater wooden barrels are all oak barrels, and they are also used with airtight corks.
Marlin's method is to put the oak barrel in the fresh water, put the oak barrel in a large pot and cook it. Cook until it's hot, then take it out and air dry the outer wall of the wooden barrel.
As for the problem of airtightness of corks, Marin does not have that much wax to seal. However, when the cork is wet, he can apply mud on the outside of the cork ...
In this way, when the outside of the barrel and the cork are dried, the mud on the cork is also dried. Hardened soil can also play a great role in gas-holding. Of course, when storing the bucket, pay attention to dryness. Because the mud blocks soften when they meet the water.
In this way, the fresh water stored in oak barrels is basically not much different from canned food. At most, the soil seal is not as good as the wax seal. But in this way, at least fresh water is not bad for a few months.
However, taking into account the difficulties in obtaining fuel during the cruise. Marin once again courageously "invented" the legendary solar cooker, because tinplate was not used for reflection, and tinplate was not. Although Marin could make tinplate, but time was too tight, Marin simply made a solar cooker from copper. The reflectivity of the copper skin is also good enough to heat the cauldron.
This way, you don't need to bring too much fuel when you are sailing. Of course, you have to bring some fuel. Because, in rainy weather, the solar stove is useless, and it still has to rely on ordinary fuel. Therefore, I put on a batch of briquettes to heat food in rainy weather.
In fact, Marin's treatment is much better than ordinary sailors. In the early big voyages, in order to save space, fuel was rarely carried. Sailors, I usually eat foods that do not need to be heated, such as ham and bacon. Where can I drink hot things? Only when they have just left a supply coast will a pile of firewood cut down from the land mountain be put on. During this time, the sailors were able to eat hot food for a period of time. And in the middle of the sea, everyone simmered ham and bacon to maintain ...
伦 Columbus was surprised at the solar stove that Marin "invented". And the kidnapped Da Vinci was also surprised by the size of Marin's brain ...
In addition, in order to prevent scurvy, Marin took out a dozen sacks of lemon leaves and gave them to Columbus. And, it is mandatory that everyone, including Columbus, must soak lemon leaf fragments with water and drink three glasses a day.
Of course, because there are many people who are uneasy about wearing Marin, such as two Portuguese translators hired. So Marin stayed.
In order to hide the smell of lemon leaves, Marin stirred a lot of spices such as pepper powder and powder in the pieces of lemon leaves to disturb the smell of the lemon leaves. Although it is put less, the spice smell is already heavy and it can basically disturb the taste.
Furthermore, Marin quietly told Columbus and the other three captains privately that drinking this "herbal" water every day could prevent scurvy ...
The other three didn't feel much about it, but Columbus was surprised ...
You know, a sailor died of scurvy when he discovered America's voyage. As a result, Columbus has discovered that voyages on the oceans have a high chance of developing scurvy. Marin even said that this herb could prevent scurvy, which made him doubtful.
"Captain Zorro, this was taught by my teacher Einstein. My war-fighting skills are also passed down from the teacher ..." Marin explained.
Columbus, although he still had some doubts in his heart, said nothing. And, if this herb really prevents scurvy, it would be great for sailing.
Before the four captains left, Marin repeatedly told him that he only needed to tell sailors that he must drink the water soaked in this herbal medicine every day, and he could not tell the secret of this herbal medicine to prevent scurvy. Otherwise, if Portugal and Spain knew they had a way to deal with scurvy, they would probably co-operate to force themselves to surrender the secret recipe ...
Uh ...
In addition, Marin secretly gave Columbus a telescope. This telescope is very unusual. The glass it uses is high-grade colorless glass made in Venice. Even in Venice, this colorless glass industry is rare.
Marin bought a batch of high-grade colorless glass last time and commissioned different opticians to polish into concave and convex lenses. After testing, this new telescope can completely see objects at the position of the horizontal line on the distant sea surface. Of course, you can only see what it is, not the specific details.
As for the specific distance, Marin also tested it himself ...
In fine weather, standing at sea level, you can see as much as 7 kilometers away. This distance is exactly the distance from your position to the horizontal line. However, if you stand on the shipyard of the latest Karak sailing boat, the captain's room, which is a few meters high, can be seen more than 20 kilometers away. Of course, in rainy weather, this distance should be shortened.
He gave Columbus a telescope just to make it easier for him to track Da Gama's fleet ...
Huanda Gamma's fleet is still observing with the human eye and cannot compete with telescopes. As long as Columbus took the fleet to hang about 20 kilometers behind Da Gama's fleet, Da Gama's sailors were hard to find. Even if he found out that he wanted to make a U-turn, 20 kilometers across would be enough for Columbus to respond. Dalgama's Karak sailing ship is not faster than the Karak sailing ship ordered by Marin. There is no way to chase it. Although the Caravel sails quickly, there is no way to catch up. As a result, Columbus can safely walk to Dammam.
When he arrived at Gamma for the first time at Mombasa, according to Malin's plan, Columbus should go straight to the north and go to Malindi. Also, tell Chief Malindi that he is an enemy of Mombasa, and then trick Maguid as a pilot ...
Before leaving, Marin also secretly handed over to Columbus a contour map of the African continent and maps of the Indian Ocean and the Arabian Sea, cut from the standard world map of future generations ...
"Master, how did you get this map? Is it accurate?" Columbus was surprised again. The presence of this map does not mean that the sages have already explored the route? Then he probed a hammer?
"Cough, this is my teacher's collection of Portuguese data, and the route map of the distant Eastern Ming Empire navigation chart ..."
"Ming Empire?"
"Well, there was a navigator named Zheng He in that empire. He had been to India and to the east coast of Africa ... My teacher walked the whole world and got this pattern in the East ..." Marin It was true that Zheng He had been to East Africa, even if someone had verified it, he could know this fact and was not afraid to help.
Columbus now calls himself Captain Zorro, and cannot call himself Columbus. Because he has too many enemies ... Those who died of syphilis have put their account on Columbus ...
In order to win Columbus, Marin named one of the two Karak sailing ships "Columbus", which moved Columbus very much.
You know, exploring the real India is an absolute event. The vessels involved in this voyage will also be known for many years. Columbus can no longer show people in true face, otherwise there is no guarantee that they will not be killed. However, Marin named the ship Columbus, but others would not come to Marin.
This way ~ EbookFREE.me ~ Columbus's name can also be remembered as a true Indian ... for a navigator, this is the best praise ...
Be aware that before Columbus explored the New World, and this year Da Gama explored India, the names of the ships were basically saints. For example, Columbus's flagship Santa Maria and Da Gama's flagship San Gabriel. Columbus's name could become one of the four ships, which definitely counted as Columbus's face.
As for the other three ships, Marin also did not name it according to common sense. The flagship is named "Wadden Warrior", and the other two Kirk sailboats are named "Huffman Family" and "Mrs. Mary" ...
After everything was ready, Columbus took 4 ships, 160 sailors, and a full load of cargo and ammunition, left Tholencher, and went to Portugal to chase Da Gama ...
Columbus was very puzzled about how Marin knew Da Gama's departure date, but Marin said that he had obtained information from Jewish merchants, and he was so confused.
Before leaving, Marin took the master Da Vinci, and several folk musicians who could play the instrument, performed a shocking piece of music-"Conquest of Heaven" on the pier ... Of course, this era of strong religious power , Marin did not dare to use the name Conquer Heaven, but renamed it to "Conquer the Ocean" ...
This was used by future generations to commemorate Columbus' discovery of the New World, but at this time, Marin used it to encourage Columbus to discover India ...
In the shocking "Conquest of Paradise" music, Columbus and his sailors bid farewell to their loved ones and embarked on the journey to conquer the Indian route ~ EbookFREE.me ~ Welcome the book readers to read the latest, fastest, most Fire serial works are all in ~ EbookFREE.me ~ Mobile users please read.
