Chapter 699 Classified Elective Teaching (Please vote and subscribe)
The clanging sound of iron forging rang out in the camp. Dozens of craftsmen from the Han tribe were busy in the temporary workshop. There were also many apprentices who came to the camp to learn technology. Of course, the apprentices could not touch the hammer at all. Their current task was only to add charcoal and pull the bellows.
Although they were wearing thin clothes, they were sweating all over.
Iron forging is a technical job, but it is not particularly difficult. To put it bluntly, it is actually a bit similar to kneading mud. Both are the work of shaping materials, but one is done by hand and the other is done with a hammer.
The young apprentices looked at the steel ingots unloaded from the ship and turned into various exquisite tools in the hands of the masters, and their eyes were full of deep envy.
Kitchen knives, farm tools, tools, these are the most scarce things in the camp at present, but fortunately, after the workshop started, the shortage of these materials has been alleviated.
The men in the camp hunting team are now all equipped with newly made long-handled axes and hatchets. While it is not snowing yet, they have to go and chop more firewood. The firewood stored in the camp is enough, but now so many people have come, and the blacksmiths and carpenters also need wood and charcoal to make things, so they have no choice but to go to the mountains to chop wood again.
The rest of the half-grown children and some men in the camp, as long as they are not involved in hunting, logging and patrolling, have almost been organized to learn skills.
Farm tools are already in intense production, but it is also a big problem that there are farm tools but no one knows how to use them. Spring plowing must start on time in the spring, and farm tools will definitely be ready by then, but people who use farm tools must also learn in advance.
There are officials from the Sinong Temple of the Han tribe who are specially guiding them. The people also know that this is an important livelihood skill of the Han tribe, so they study very seriously. After all, they have seen and eaten the corn they grew with their own eyes.
This feeling of having food to eat as long as they work hard is something they never dared to imagine before. Moreover, although farming is hard, it is safe and much easier than going out to gather and hunt.
However, due to the conditions of the temporary camp, they can only use human plows to cultivate the land. After all, there are very few livestock, and the only dozen wild donkeys have to undertake heavy transportation work.
The big man in charge of water conservancy in Sinong Temple is also busy with field surveys. They have to combine the local topography and the direction of water sources to reasonably plan the scope of reclamation. This is a delicate job.
The land near the banks on both sides of the valley has all been planned as rice fields, which is convenient for irrigation. As for corn, it has strong adaptability and is drought-resistant and cold-resistant. It is more appropriate to plant it on the hillside, but it is a little troublesome to divert water. It is possible to build several reservoirs on the hillside and then use water trucks to lift water from below.
Farmland planning and agricultural technology training are in full swing. The women in the camp are also busy. They are organized to learn needlework, how to cut and sew clothes for the Han tribe, and introduce the clothing characteristics of the Han tribe.
Textiles are also indispensable. Although there are not many looms brought this time, there are many spinning machines, and some looms that have been eliminated. Although they do not expect the cloth produced by the camp to meet the needs of everyone, they have to make the sacks for food by themselves. The Han tribe cannot prepare everything for them.
In addition, in terms of textile raw materials, the Han tribe also provides the camp with various hemp grass and cotton seeds, so that they can choose to cultivate and plant them.
There are also many vegetable seeds. Generally, such things are planted in the auxiliary fields of women in the Han tribe, so women also have to learn about vegetable planting.
However, everyone's enthusiasm is very high. This kind of life where they can get stable food without collecting everywhere is what they dream of.
Even some girls who were about to reach adulthood in the camp could not help but feel amorous when they saw the men coming from the Han tribe. If they could marry into the Han tribe, it might be a good choice.
It was a pity that most of the people who came this time had wives. After all, those who were not yet adults would not be assigned jobs, let alone come here.
On the other side, Luo Chong was still directing the shipbuilding at the Liuyang County Shipyard of the Han tribe.
The 80-meter-long ship was the first to be built by the Han tribe. Its size and complexity were no less than building a school. After all, it was larger than any teaching building in the Han tribe.
There were a total of eight floors of cabins, which would be a high-rise building on land. There were two floors of space below the waterline, which were mainly used to store supplies. Gunpowder, fresh water, food, and shells were basically on the three floors below. The three floors in the middle were the gun decks. One hundred and twenty standard guns were arranged on the left and right sides. Portholes were opened on the bulwarks to serve as firing ports for the guns. There were sixty guns on each side, and 20 guns on each floor.
The stairs for going up and down the cabin are located on the central axis of the hull. However, there are shafts and skylights for transporting supplies between the gun positions on both sides and the stairs. In wartime, gunpowder and shells can be quickly transported up from the bottom warehouse with slings and pulleys.
Going up is the open-air deck. As for the seventh and eighth floors, they are the mast towers located at the stern. The seventh floor is the kitchen and restaurant, and the eighth floor is the combat command room and conference room. It is the commanding height of the entire ship, with a good view and convenient command.
The power layout of this battleship adopts a five-mast horizontal sail layout, four main masts, and a diagonal mast at the bow. Although the traditionally simple longitudinal sails are abandoned, the horizontal sails are more flexible and the sail surface can be made wider, which can also provide more sufficient power.
More importantly, because the longitudinal sails like to eat crosswinds, the sails often have to be adjusted at an oblique angle. In this way, the ship will inevitably tilt sideways, which is all caused by the masts.
But the purpose of this ship is a gunboat. If the ship tilts, the guns will probably slide to one side. How can we fight then?
Moreover, even if the guns are fixed and will not slide, the pitch angle will still change due to the tilt of the hull. The guns are very demanding on the pitch angle. If the height difference is one degree, the range will be hundreds or thousands of meters off.
The operation of the cross sail may be more troublesome, but the advantage is that it is not easy to tilt the hull, which is why Luo Chong chose to use the cross sail layout.
The round bow and flat stern hull with a length-to-width ratio of 80 meters and 18 meters, plus four main sails, is absolutely fast. Although the displacement has exceeded 10,000 tons, it is full of power.
However, the mast of such a large ship is not easy to find. It can only be made by mortise and tenon splicing and steel ring tightening. It is not easy to find a natural giant wood for the mast. Even if you find it, it is not easy to transport and handle.
Because for a sailboat, the height of the mast generally cannot be less than the length of the ship. Think about it, this is the height above the top deck, which means that the main masts of the ship are almost 100 meters high. The thickness of the mast is so large that an adult cannot hug it because it is a pillar.
The huge hull was also severely tested in terms of load-bearing and pressure-bearing. In order to support such a huge hull and water pressure, the keel and ribs used inside were all very thick. The thickness of the outer plate of the hull was 25 cm. It could not be called a plate, but a beam or a column, but it was used to wrap the outside.
Such thick wood needs to be completely softened before it can be installed on the skeleton, so it needs to be steamed for a long time in advance. For this reason, Luo Chong also specially asked people to build some new steamers for ship boards.
The installation method of such thick wood boards is also a big trouble. The craftsmen had no choice but to come up with ideas by themselves. Finally, the rope was used to fix and tighten, and then the hot riveting process of drilling holes first and then nailing was used to install it.
This is the most convenient and strongest connection method when there is no lathe to make large bolts. Most of the steel frame bridges in the early days of the previous life were also made using this process. Luo Chong used the same technology to build a sailboat, so there was no problem.
The remaining part is waterproofing. The prosperous shipbuilding industry of the Han tribe has a growing demand for glue. Whether it is pig skin or fish bladder, it is not enough. Fortunately, the Han tribe now has a new waterproof gel material.
That is asphalt extracted from coal tar.
Mix hemp fiber, sawdust, gypsum powder or crushed oyster shells with asphalt to make a black waterproof filler and apply it to the gaps in the shipboard. Then fill it with hemp rope and asphalt several times, and finally scrape it flat with asphalt, and then apply a layer of paint to cover and beautify the appearance. The waterproofing work is completed.
Asphalt is just a by-product of the coking plant. It has never been used. Now it is finally time to show its value.
The output of this thing has always been embarrassing. When asphalt was first made, Luo Chong originally planned to build an asphalt road or something. Later, thinking about the output of asphalt, forget it. It is estimated that it is not enough to make a waterproof felt. But now it is used to waterproof sailboats. These few outputs can still be supplied.
As for waterproof glue, asphalt is definitely the best choice.
In addition, because many auxiliary industries of the Han tribe began to develop, Luo Chong spent a lot of money to decorate the two-story stern of the ship. The transparent glass windows on the three sides allow people to clearly see the situation outside when standing in the command room. It can definitely be called luxurious, but for better command conditions, Luo Chong did not skimp on this.
There are several copper-plated metal pipes in the command room of the stern. In fact, this thing is the ship's intercom. The speakers at both ends are made of copper, but some unimportant sound tubes in the middle are replaced by bamboo tubes by Luo Chong.
All parts are made separately, and they are ready to be assembled together when the hull is almost built. Fortunately, it is winter now, and many people are in a state of slack farming and wintering. There are many people willing to come to the shipyard or various workshops to do odd jobs, which speeds up the progress of shipbuilding in disguise.
In this way, this giant ship belonging to the Han tribe has the hope of being successfully launched before the beginning of spring.
As for the cannons on the ship, they will be installed last. They will be installed one by one when the ship is launched and outfitted.
The entire shipbuilding work is in full swing. After Luo Chong arranged everything, he set off to go home.
The hardware level of the Han tribe has been improving rapidly, and the software must naturally keep up.
First, he went home to spend a few days with his wife and children. After moving into the new house, Luo Chong's family's living standards have improved a lot. Although it is winter now, the two children can also have the opportunity to bask in the sun in the glass house upstairs, which is a treatment that other children cannot enjoy.
If the Han tribe wants to use glass windows for all people, there is still a long way to go. Now it is limited by production capacity issues, and glass can only exist as a luxury.
Little Luo Cheng and Luo Lan were wearing one-piece cotton-padded clothes sewn by Xiao Die, and tiger-head hats on their heads. They were playing with building blocks in the glass room upstairs. According to the time on Earth, the two children were almost one year old now, and could already walk slowly by holding on to the wall. They were at their most naughty. Fortunately, Luo Chong prepared a lot of toys for them, so they stayed in the house honestly.
Although Luo Chong stayed at home to rest, he still did not let the people below idle. He took advantage of the few days he was home to issue orders to all counties and prefectures, mobilizing the records of birth deaths and the deaths of the people from illness in recent years, and then asked all places to summarize the data. There were
also all the records of conferring titles and granting land for such events since the promulgation of the merit system, and finally the summary of the names of the medicinal materials that the Han tribe had identified as effective.
Collecting these data and information was naturally to prepare to make a contribution to the medical cause of the Han tribe.
It has been two years since the Han tribe established a government-run school. The earliest batch of students will graduate in another year. What will they do after graduation?
Should they go home to farm directly, or select outstanding talents to join the Han tribe in various industries, or continue to study.
Of course, all of these are possible, but if they continue to study, what should they learn?
Luo Chong's idea is to directly sign up for self-study and study in different subjects. He plans to set up a professional medical school to train medical talents for the Han tribe in a systematic way. After all, medicine is also an important part of society that can increase life expectancy, and he cannot help but pay attention to it. There
is also a comprehensive military and police academy, which teaches investigation and case solving, or logical reasoning, and knowledge of military command. However, since it is an unpopular profession, there will definitely not be many people, so they can just teach together.
There is also an advanced version of the Academy of Sciences. This school is a direction for ordinary students to continue their studies. The content of study is a higher level of mathematics, physical chemistry, and biology. According to the current name, it should be regarded as a polytechnic college, but the knowledge level defined by Luo Chong is far from the current university level. At most, it is between the level of junior high school and high school, and it mainly provides talents for various scientific research directions of the Han tribe.
The last college that focuses on training can be seen as an advanced college for liberal arts students. It is mainly aimed at training administrative officials. In addition to teaching more advanced literature and mathematics to improve students' basic knowledge level, the school will also conduct systematic training and teaching on current affairs, policy discussions, persuading farmers to learn, administrative management, urban planning and construction, and other work that officials need to understand, specifically training and exporting more grassroots backbone officials for the Han tribe.
