180. Sand Mining (11/20, 30050 League +1)

In reluctance, Yang Shubao said goodbye to the beautiful and elegant flamingo.

The bird's diet is algae and plankton, and the reserve cannot feed them.

"I fell in love with a herd of wild horses, but I don't have a prairie at home. He started the car and started singing, and the flamingos were frightened again, and flapped their wings and flew away.

There are many reeds growing along the tail river, and large areas of grass cover the land, and the snow-white reeds are spread left and right when the wind blows, and the posture is beautiful.

The reeds are the best habitat for many wild birds, but they fly so fast that they are often fleeting, and Yang Shubao did not recognize them.

Until the car drove to its destination, there were some large trees growing on the riverbank, they did not have many leaves, lush branches, black color and extremely rough bark, Yang Shubao had never seen this kind of tree and stared at it twice.

Jill introduced him: "You haven't seen it? This is windmill wood, and a lot of windmill wood from Africa will be exported to you Asia, and they are very good, very hard, very wear-resistant, very corrosion-resistant. ”

Yang Shubao shook his head and said, "I haven't seen them, but it's really good to hear you introduce them, and they can be made into high-end furniture, right?"

"No, no, they are not suitable for furniture, because they are too hard, they are very tough, and they would rather bend than bend, and if you make furniture out of them, there are only two states of furniture, one is strong and beautiful, and the other is crumbling and ruined," Jill said. However, they can be used for flooring, and I read a magazine that said that this kind of wood is now popular in Asian villas for flooring, which is actually a bit wasteful. ”

"What should I do with them if I don't waste them?" asked Yang Shubao as he surveyed his surroundings.

"Of course, they are burned to make bonfires, they are very dense and very resistant to burning. ”

Yang Shubao nodded and did not speak.

At this point the river began to bend, and the rushing water crashed against the banks and turned, and here their momentum was frustrated, so that the sediment carried all the way upstream was left behind, and only the water was sent into Lake St. Lucia.

There was a boat hidden in the reeds, and Jill said their boat was inside.

The two went to fetch the boat, and after pushing away the reeds and grass, a large pelican bird flapped its wings in horror.

Jill touched his back and said regretfully: "I didn't bring a gun, otherwise we can eat roast pelicans at noon, their meat is very good, tender and fragrant, better than animal meat." ”

Yang Shubao smiled: "Forget it, I don't have a hunting license, if I hunt wild animals here, it will be illegal." ”

"So it's up to me, we Zulu people have lived off the meat of animals and poultry for generations, and we are free to hunt them, of course only for food and not for indifferent killing. ”

Hidden in the thick and dense grass is a primitive African canoe, made from a tree trunk, with the side branches cut off, one side hollowed out for sitting, and a pair of oars to travel through rivers and lakes.

Yang Shubao asked, "Is this your ship?"

Jill said, "No, I don't know which tribe's ship it is. ”

"Aren't they afraid to steal it when they put it here?"

Jill said, "There are no oars on the boat, how can you take them away if you steal them? Drag them ashore and pull them away in a car? That is impossible, if the thief has a car, he does not have to be a thief." ”

Yang Shubao laughed, this is an interesting logic, it turns out that South African thieves are also so lazy.

Jill thought for a moment and asked, "Is it the first time you've seen such a thing as a bush hiding a ship?"

Yang Shubao said: "Yes. ”

Jill beckoned to him and said, "Then I have to open your eyes, you be careful to follow me, if you see a canoe docked on the bank of the river in the future, don't approach it yourself, let alone try to enter it, it often has traps in it." ”

In order to prevent the rain from falling, the canoe was covered with a layer of broken cowhide, and Jill took a stick and carefully picked open the cowhide, and a snake's head burst out of it and pecked at the stick.

Yang Shubao was startled: "Why are there snakes in here?"

Jill said, "Don't you think the owner of the boat will keep his hands on it? This is a water snake, and all the water snakes you know are poisonous and very dangerous." ”

Yang Shubao said in surprise: "But why did this water snake stay on this ship honestly?

He was thinking that if there were tribes in Africa that could tame the water snakes, then it would be no problem for the Warcraft elves to give the animals some wisdom.

Then Jill laughed and said, "You asked a stupid question, who can tame the water snake? It's that its tail is tied to the boat, so it can't go anywhere." ”

The tin boats used to pump sand were deeper and they had to wade through the water, and Jill told him that there were water snakes and crocodiles underwater, and that he had to be careful.

"But whether it's a crocodile or a water snake, as long as you don't provoke them, they won't attack you, in fact, they will be scared when they see someone. Jill introduced him.

After walking more than ten meters in the river, the iron boat parked on the water revealed its true face.

The boat was more than ten meters long, it was converted from a barge, and there was nothing on it, and it had to be temporarily equipped with machinery, so the Gil family was not afraid of someone stealing things, because it was a rusty empty iron shell.

Sand pumping requires sand pumps, jet pumps, and diesel engines, all of which are hidden in other places, and Jill sees that no one around takes Yang Shubao to find a cellar in the windmill woods on the bank of the river, where everything is located.

Jill jumped down to carry the machine out, and handed over the supporting tools such as the saloon head, sand pumping pipe, and head pipe to Yang Shubao, and they tinkered with it several times, and then assembled the sand pumping boat.

Diesel poured into the engine, the machine rumbled and began to run, Jill went to block the pipe mouth, and after a while he jerked his hand away, and some muddy muddy water was sprayed out under the pressure.

Yang Shubao saw such a sand mining method for the first time, which was an eye-opener.

In fact, the machine they use should not be called a sand pumping boat, but a sand pumping platform, because it is not a ship at all.

However, this cheap and non-technical sand pumping platform is more suitable for the needs of the locals, the sediment resources in the river are abundant, and the locals do not pump much sediment at a time, and the continuous flow of water brings endless sand, and new sediment will be replenished in a few days.

The machine pumps sand, the sediment is left on the boat first, and then the boat is connected to the wide-sided plastic raft, and Jill washes the pumped sediment with a water pump, so that the sediment is washed up on the plastic raft together, and finally the muddy water flows back into the river and the sand remains on the raft, Yang Shubao takes people to drag the raft to the shore and then transfer the sand to the board truck.

Compared with the domestic sand pumping operation, this is undoubtedly very difficult, but considering the local conditions, the Zulu people can have such sand mining technology is good, in fact, many tribes still rely on primitive means to mine sand in the river: use basins with water to scoop sand ashore.

Then they talked about this, and Jill said: "We used to do this and it was very inefficient, but then I went to the thrift market and bought these machines and assembled them into a sand pumping boat like this, which improved the efficiency." ”

Yang Shubao asked, "You assembled this ship?"

Jill nodded and said happily: "Yes, it cost a total of two thousand yuan, isn't it?"

It's amazing that this price can assemble a sand pumping boat, and Yang Shubao is ashamed of the creativity of laughing at Jill before, and he no longer dares to underestimate the heroes of the world.
