Chapter 68 Irrigation Dams
Li Tu demanded that the name of the builder be engraved on the butt of each arquebus. Pen? Interesting? Pavilion wWw. biquge。 infoIf the boring is fried, the producer must be held responsible, the revolution is not a dinner party, and the first fried-boring will be fined a year's salary! If the second and third time always makes a boring arquebus, Li Tu will be punished with a knife.
The craftsmen used to make birds, too. The reason why the bird guns in the guard house are always fried and boring is because the officials of the guard house blindly suppress the reasonable needs of the craftsmen, and there is no reward and punishment system, so the craftsmen are passive and shoddy. Under the coercion and temptation of Li Tu, and under the guidance of Genjiro Matsuda, these craftsmen are now very serious in the blacksmith shop in Deyuan City and will not hand over defective products.
Li Tu took the flintlock pistol given to him by the British and gave it to the craftsmen to imitate.
Genjiro Matsuda was a craftsman who liked to ponder, and when he got the flintlock pistol, he played with it for a few days. The firing mechanism of the flintlock pistol was not complicated, and after a little thought, Genjiro Matsuda came up with the method of the flintlock ignition device and taught it to other craftsmen.
Motivated by the reward and punishment system, the craftsmen of the blacksmith shop are all dedicated. Genjiro Matsuda continued to give lectures, explaining individually, and passed on all the techniques he knew to other craftsmen.
On the construction side of the dormitory, by the end of April, all the logs and building materials on the construction site had been prepared, and only carpentry work remained. Li Tu only left more than 100 carpenters and 100 laborers to continue building the house. Others, all of them devoted themselves to the work of clearing the wasteland.
Li Tu had repeatedly explored before, and finally took a fancy to a forest slightly higher than the river in the valley of the small river one mile outside the dormitory, and chose it as the target for land reclamation. The forest is on the north bank of the river, eight kilometers long and four kilometers wide. Close to the river, fertile soil. The ground is higher than the creek and is not flooded by the river during the flood season.
Li Tu drew boundaries at the boundaries of the forest, and organized farmers to cut down and drag all the trees at the border to form a 30-meter-wide border without combustibles. Then, taking advantage of the dry days when there was no rain for three or four days, Li Tu led the peasants everywhere to light fires and set the whole forest on fire.
The spark gradually ignited. Catalyzed by thousands of fire sources on the outskirts of the forest, the fire spread extremely quickly and soon burned deep into the forest. An hour later, the entire forest turned into a fireground. Standing fifty meters away from the fire, Li Tu could feel the heat wave coming in. The birds and beasts of the forest have fallen into bad luck and fled in all directions. Some birds and beasts that were running slowly were charred by the fire.
Looking at the monstrous fire, Xue Yiming, the head of the Crescent Ship, said worriedly: "Owner, have you paid attention, the soil of this land is fertile, but the trees on this land are all new, and there are no big trees that are more than three years old. ”
Li Tu was stunned, not knowing what Xue Yiming meant.
Xue Yiming twisted his beard and said slowly: "According to the old man's observation, this land is a slash-and-burn farming land. Every few years, they come and burn the forest and plant it for a year. After planting for a year, the land is abandoned and the forest is burned elsewhere. After a pause, Xue Yiming said: "Now that we occupy their land, I'm afraid we will have a conflict with them!" ”
Li Tu said: "Shengfan's combat effectiveness is low, don't be afraid of them!" I'll set up some sentry posts on the perimeter to keep it guarded. ”
On weekdays, Li Tu is honest and trustworthy and reasonable to his compatriots and Japanese, and Xue Yiming saw that he would shout and kill whenever he met a foreign race at this time, and he couldn't help but look at Li Tu playfully.
It took three full days for the raging fire to burn out, and the whole forest was burned to ashes. These plant ashes are rich in various elements and are good natural fertilizers. The harvest at the end of the year depends on these ashes.
A new field was burned, and Li Tu led the farmers to build a small dam in a narrow river valley upstream of the field. The upper reaches of this small river are just in a valley with hills on both sides, which is a good place to build a dam.
The dam was built to raise the water level and provide water for the irrigation canal. It took 20 days to build two trapezoidal earth dams on both sides of the river, which were 300 meters long, 10 meters wide and 5 meters high, connecting the hills on both sides of the river valley.
Looking at the 300-meter-long earthen dam, Xue Yiming said: "The dam built by the main ship is not only irrigating these 30,000 acres of fields!" ”
Li Tu nodded and said, "Once the dam is built, the south bank of the river can also irrigate tens of thousands of acres of fields!" ”
Xue Yiming twisted his beard and said, "The owner's courage is getting bigger and bigger!" ”
Li Tu smiled and did not speak.
Li Tu brought a large number of bluestone slabs from Zhangzhou, and after building irrigation outlets and spillways with bluestone slabs on the earthen dam, he instructed the peasants to pile stones into the river. Large chunks of stones were thrown into the river and gradually piled up into a sill, blocking the river. The laborers then filled in the earth at the interface, compacted it, and when the embankment was built to the same height as the earthen embankments on both sides, the earthen dam was closed.
As soon as the earthen dam is closed, the river has nowhere to vent, and it accumulates in the valley between the earthen dam and the hill, becoming a small reservoir five meters high. Water from the reservoir does not flow out of the irrigation outlet above the earthen dam until the height of the reservoir exceeds the height of the irrigation inlet.
In this era, such a dam is already a good hydraulic project. On the day it was built, the farmers stood near the irrigation outlet and looked at the water flowing out, as if they had seen a good harvest day, and they were all very excited.
With a small reservoir, it is easy to build irrigation canals, and the only thing to pay attention to is the drop.
In mid-May, the blacksmith made the first batch of thirty-one flintlock pistols. Li Tu asked people to test shoot these flintlock pistols, and all of them passed. These flintlock pistols fire faster than arquebuses, saving considerable firing time.
Li Tu was ahead of this era and said goodbye to the arquebus and entered the era of flintlock pistols
Counting the cost of materials and wages, these thirty-one flintlock pistols cost only one hundred and twenty taels of silver. Compared with an iron cannon of fifty pieces, it is really cost-effective to build your own gun. Li Tu equipped the guns with the crew of the Zaixing. The iron cannons eliminated by the crew were equipped with the Selective Battalion, which had been training for two months.
Seeing that Genjiro Matsuda was qualified for the work of the head craftsman, Li Tu was happy and brought a general to find him.
"Craftsman, all the thirty-one rifles this month are qualified, and in addition to the fixed honorarium, you also have a bonus of nine taels of silver."
Genjiro Matsuda is paid no more than 30 times a year in Japan. Now that he had earned so much silver in a month, he was overjoyed, licked his lips and said, "Thank you, Dudu! ”
Li Tu asked casually: "How did you make this barrel?" ”
Genjiro Matsuda listened to Li Tu's technical questions, and his eyebrows fluttered with excitement. He took Li Tu to the blacksmith's shop, pointed to a semicircular steel groove, and said, "We have burned the wrought iron sheet red, and a steel bar is padded in the middle, and in this groove is hammered into the barrel of a gun. Then use iron powder and borax to weld the gaps. Pointing to another drilling machine, Genjiro Matsuda added: "After the barrel is roughened, we put the barrel on the drilling machine and drill holes, and little by little replace it with a larger drill bit until a smooth bore is drilled in the barrel." ”
Li Tu then asked, "How do you prevent the flintlock pistol from exploding?" ”
Hearing Li Tu ask about his tricks, Genjiro Matsuda straightened his waist proudly, picked up a freshly drilled barrel, and said with a smile: "You don't know this!" After the barrel is ready, we put four times the usual gunpowder in the chamber ****** explode once, and if the chamber does not crack after the explosion, the barrel is adopted! The barrel of the exploding gun is disposed of as a scrap! ”
