Although the two of them had a weak mentality when facing Doug, they regained their confidence when they saw the children with runny noses and some stains on their faces.

"I am John, and from today on your teacher... Turn the textbooks in your hands to the third page, and I will read them first..."

John started talking.

Specializes in profession.

Although Doug has a more profound knowledge and a good skill in inciting people's hearts, he is not as comfortable as John when facing these little devils.

Half an hour passed and John finished speaking.

After ten minutes of rest, it was time for Taylor to give a lecture again.

Confirm that the ringtone for get out of class is not repeated continuously with one tone.

Instead, a few bells that are of different sizes are knocked down with a wooden hammer. The adjustment is raised during class and the adjustment is lowered after class.

The sound of this bell is not small, and can be heard in the entire printing and dyeing factory.

Parents of students who sent their children here to study, when they were working, they heard the ringtone ringing every once in a while, and their happy smiles appeared on their faces, and their initiative in working has improved a lot.

Because, when they hear this ringtone, they know that their children are studying.

When your children are studying, it means that they no longer have to go hungry or suffer poverty, and they will have a bright future.

The performances of the two young priests were above Doug's expectations.

Although the 19th century is enough to describe it as "ancient" compared to the 21st century, people in this era are not stupid or stupid at all.

It’s just that I was born too early and I have seen too few routines.

When the children were all gone from school, Doug said to the remaining two in the classroom, "I'll just say a few words..."

...

When Doug taught the two priests, Drake had already returned from New York Harbor with a full load.

The sales of synthetic dyes are much better than he thought.

The advantages of synthetic dyes that are lower than the average single barrel price in the market are not only the cheaper single barrel price, but also the fact that after testing, a barrel of synthetic dyes can be diluted higher and more things can be dyed.

In just two days, Drake's shipment of synthetic dyes was sold out.

The North American Dye Association's document prohibiting synthetic dyes was late when the bureaucratic system knew that Drake had left the New York Harbor and chased the exhaust of the steam engine on board.

Drake looked at the small piece of paper sent by the North American Dye Association, frowned at first, but after a while, his brows stretched out.

The so-called North American Dye Association is nothing more than an industry association with no legislative power or enforcement power.

They issued such a document that prohibits synthetic dyes, and only require manufacturers that still need to use natural dyes.

However, Doug's synthetic dyes have several colors, and for some manufacturers, they can completely abandon the supply of the North American Dye Association.

However, they are not yet completely sure whether Drake has the ability to supply stably, so they are on the fence and being a middle-aged man.

...

Not only the North American Dye Association is sensitive to synthetic dyes, but also one company, DuPont, has also discovered synthetic dyes that flow into the market.

Unlike the North American Fuel Association, they did not ban this product at the first time. For DuPont, which produces explosives, they have no direct interests in synthetic dyes, but they are rich in curiosity about all the emerging artificial compounds in the world.

The synthetic dyes produced by Tom and Doug Chemical were immediately taken back to the DuPont factory by the Brandy River in Delaware.

"Analyze the structure of this synthetic dye."

"Is it an azo dye? Structurally, is there a chance to explode?"
