Chapter 1424 Four Peaks Island

The flat jars and chairs have now been cultivated by Chen Zhaoming, Su Xiaomei, Shi Fu, Su You, Shi Wei and others, and they already have a belly of knowledge.

In the eighteenth century, there was a profession in the West that was more in line with their present state - naturalists.

Now they have the rudiments of "naturalists".

Sailing is a big project, nominally, the captain of the L-Snail is Zhao Xiaoyi, but in fact it is a flat tank.

After announcing the task, the first thing Bian Tank did was to make a clear division of labor for various errands on the ship, set up the type of work, and then assign shift tasks, and establish an emergency system, so that the originally well-organized ship affairs became more reasonable, not only in order, but also the crew had a lot of free time.

During these times, Flat Tank arranged study tasks, with physical training in the morning, and then the crew of the Polytechnic background, including himself, had to learn practical operations from the sailors, such as mast loading, sail repair, lookout, mooring, and steering.

There's even fishing, deck washing......

As for the sailors, they have to learn a series of more complex shipping tasks such as literacy, mathematics, surveying, navigation records, flag language, and light language, as well as a series of skills such as equipment maintenance, gun manipulation, gun manipulation, and even boiler machine tool maintenance and repair.

There are also countless games in the evening, such as chess, backgammon, checkers, and the most popular among sailors, of course, playing cards......

If you don't go ashore for a long time, it will cause people psychological problems, but under Zhao Da's brainwashing and the careful arrangement of flat can children's shoes, the crew has an extremely fulfilling life.

When people are empty, they will have psychological problems.

The L-Screw is a polytechnic test ship, equipped with all kinds of observation equipment, all kinds of materials, and even a new thing - a marine clock.

This was commissioned by Zhao Zongyou to Shi Fu to customize.

On the navigation clock, because of the blind spot of Su You's knowledge, it led to a small detour.

The earliest marine bells were designed to be relatively large, because through the design of the Bianjing Bell Tower, everyone believed that the larger the individual bell, the smaller the error brought about, that is, the more accurate it was.

In order to resist the impact of the waves on the pendulum, Zhao Zongyou and Shi Fu put a lot of effort into the pendulum control.

It wasn't until the third year of Yuanfeng that Zhao Ji prepared to pretend to be forced at the Great Dynasty Meeting, asking Shi Fu to design a table clock that could show the magnificence of the Great Song Dynasty and be placed in the Zichen Palace, and after the military put forward the demand for a clock that could be carried with the army, the design work of the miniaturization of clocks and watches was put on the agenda.

In order to solve this problem, Shi Fu gradually added a series of special devices such as hairsprings, tourbillons, and sesame chains to the small clock, freeing himself from the shackles of the pendulum.

The final small clock, such as the one used in the flood discharge at the mouth of the Xuanfang, has been able to achieve an error of one second in three days.

Later, that kind of bell was carried onto the sea ship by Zhao Zongyou, and it was found that it was much more accurate than the navigation bell.

Studying its principle, the original high-frequency reciprocating tourbillon structure is far more stable than the traditional pendulum, and it can be accurate even in the waves!

This discovery completely opened Shi Fu's mind, since he can maintain accuracy at sea, what about on horseback? And in people?

Clocks can continue to get smaller!

But that's another issue, and now the marine clock on the left-hand screw is mounted on a gyroscope and can provide accurate time indication.

The reason why a clock is needed for navigation is mainly because it can be used to calculate the longitude of the ship.

The latitude is very simple, the sextant is pointed at the North Star, and the angle obtained is.

Longitude is more troublesome.

Before the clock came out, it needed a star chart, and the moon phase observation, also known as the celestial clock method, was used to determine the longitude.

With a clock, longitude can be calculated from the time difference, which is the clock method commonly used in later generations.

During this voyage, the flat tank and the chair had to use two methods of measurement, marking their latitude and longitude on the nautical chart every day to determine the course of the ship.

The disadvantage of the clock method is the accumulation error, and the disadvantage of the moon phase clock method is the measurement error.

The science and engineering dogs on the ship also have frequent disciplinary discussions, hold Zhuge Liang meetings, study improvement plans for observation and calculation, and solve practical problems.

Therefore, life on this ship is not only not boring, but also has a bit of a "sea academy" flavor of "unity and tension, serious and lively".

The flat tank inherited his father's prudence and attached great importance to meteorological observations, and when it came to hazy weather, the boiler had to be ignited to maintain the furnace pressure.

As soon as there is a precursor to a storm or thunderstorm, immediately drop the sails and start the boiler and flee in a southeasterly direction to avoid the storm and high waves.

It's a trick, but it's very effective, and that's the advantage of the left-handed screw.

After a few times, Long Haisheng and others admired Captain Zhao's ability so much that they threw themselves to the ground.

Beneath the ship, the warm current, known locally as the "Kuroshio" off the coast of Japan, allowed the Levorotor to sail northeastward, but as it passed through the 40th degree north latitude, the Kuroshio merged with another stream of cold water heading north, and the direction changed due east, slowing down.

In order to achieve higher speeds, the Flat Tank continued the ship northeast for several days in an attempt to take advantage of the strong westerly winds.

However, the weather became a little colder than when they set off, and it was obviously summer, and the crew all wore spring clothes, and added a velvet jacket at night.

Standing at the bow of the boat, Flat Tank and Chair watched his brothers from the Polytechnic put a wire mesh bag with a thermometer into the seawater, and said to the chair: "You can't go any further north, it's too windy." ”

At this moment, on the lookout post at the top of the mast, the son of the third lady, the second mate of the voyage, Long Wu, waved his hand excitedly: "Land - there is land in front of you - "

On May 20, the seventh year of Yuanfeng, after nearly one month and eighteen days of sailing, the L-Screw discovered an uninhabited island.

Archipelago, to be exact.

On the first island, the Polytechnic team discovered four towering volcanoes.

In the logbook, Flat Can named it "Four Peaks Islands".

It's a prehistoric world, with a lot of islands, and the whole island is a volcano, and there are no trees on the island, only grass at the bottom and snowy peaks at the top.

The island's inhabitants are seabirds and seals, densely packed on the cliffs and reefs, and they are not afraid to see the research dinghy lowered from the L-Snail.

The seals also raised their chubby heads and looked curiously at the bipeds they had never seen before.

Long Haisheng was dressed in belly plate armor, wearing a steel helmet on the bow of the ship, and holding a flat jar of the magic machine gun: "Young master, come to a gun?" ”

Flat Can smiled: "I don't need to, but the place can be recorded, look-"

Several huge whales, arching their backs from under the water's surface, exposed their breathing holes, and sprayed high columns of water into the sky, and after completing one breath, they sank again.

Long Haisheng said with a smile: "It's a pity that we are not a whaling ship, otherwise, this profit market would be big!" ”

Bian Can said: "Brother Haisheng, don't you know? Discovering that the island can also be exchanged for money, Hangzhou Bosi funded the acquisition! ”

Long Haisheng rowed a long oar and "cut": "Those profiteers in Sitong, the most valuable navigation chart is only given to a hundred times, where can you find a whale farm at home, and keep making money all year round?" ”

Feed! The flat can children's shoes were very angry, pointing at the monk and scolding the bald donkey, okay?!

I heard Long Haisheng continue: "But it's useless, even if the captain doesn't sell it, the first mate and the second mate are not afraid, sooner or later, they are all people's Sitong and the city's ship, it's better to sell it early to get money, this whale farm, I can't keep it in my hand!" ”

The boat rowed into a bay, and Long Haisheng's eyes lit up all of a sudden: "Young master, young master!" Good stuff! ”

The jutting reef in the bay is teemed with herds of small animals, hundreds or thousands of sea otters.

Long Haisheng was so excited that his face turned red: "This is the best skin!" An otter fur hat can be exchanged for a good horse in the Liao Kingdom of Goryeo! Oh my god, how many ...... are here? This is, this is a nest of money......"

Bian Can shuddered: "No, we are on the wrong path!" ”

"Huh? What does it mean? "Haisheng is a little confused, haven't you always been confident to use the west wind before?

Bian Can said: "Brother Haisheng, didn't you find it? Now the wind is getting stronger, the fog is increasing, and the sea has become too cool...... We'll have to sail southeast instead. ”

Haisheng was obviously reluctant to pay for this bay: "Young master, I finally came to the island, why don't we continue to touch the northeast along the island?" These charts are sold to Sitong, but they are all money! ”

Bian Can said: "There are less than 2,000 sea otters in this bay, and there are now five horses in Liao. Even if it is all made into leather tubes, it will not exceed 10,000 yuan, and it will not be able to change a set of houses in Bianjing City......"

"Hey!" Only then did Hai Sheng react: "I can't talk to your little young master in Bianjing!" ”
