Although the two of them were relatively weak when facing Doug, they regained their confidence when they saw the children with runny noses and unknown stains on their faces.

"I'm John, and I'm your teacher from this day forward...... Turn the textbook in your hand to the third page, and I'll read it first......"

John spoke.

There is a specialization in the art industry.

Although Doug has a deeper breadth of knowledge and a good ability to stir people's hearts, he is not as comfortable as John in the face of this group of imps.

Half an hour passed, and John was done.

After a ten-minute break, it was time for Taylor to give a lecture again.

Confirming the bell at the end of class is not a tone that repeats over and over again.

Rather, it is a few bells of different sizes, struck with a wooden hammer, and the tone is rising during class and falling tone when class is over.

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

Parents of students who send their children to study here have a happy smile on their faces when they hear the bell ringing every once in a while working, and their initiative to work has increased a lot.

Because, when they hear this bell, they know that their children are learning.

If your children are learning, it means that they will no longer have to go hungry or be poor, and they will have a bright future.

The performance of the two young priests was above Doug's expectations.

Although the nineteenth century, compared with the twenty-first century, is enough to describe it as "ancient", the people of this era are not stupid or stupid at all.

It's just that I was born too early and I've seen too few routines.

When the children were gone, Doug said to the two remaining members of the classroom, "I'll just say a few words......

……

By the time Doug was educating the two clerics, Drake had already returned from New York Harbor.

Synthetic dyes were selling far better than he thought.

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

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

The North American Dye Association's document banning synthetic dyes, under the operation of the bureaucratic system, knew that Drake had left New York Harbor, and it was only after the exhaust of the shipboard steam engine that it was belated.

Drake looked at the small piece of paper sent out by the North American Dye Association, frowning at first, but after a while, his brow relaxed.

The so-called North American Dyestuff Association is nothing more than a trade association with no legislative power and no enforcement power.

They issued such a document prohibiting synthetic dyes, and they could only ask manufacturers who still needed to use natural dyes.

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

It's just that they haven't been completely sure whether Drake has the ability to supply stably, so they are riding the wall and being a centrist.

……

It is not only the North American Dyestuff Association that is sensitive to synthetic dyes, but also one company, DuPont, has also discovered synthetic dyes that are entering the market.

Unlike the North American Fuel Association, they did not ban this product in the first place. For DuPont, which produces explosives, they have no direct interest in synthetic dyes, but they have a great curiosity about all the new artificial compounds in the world.

The synthetic dyes produced by Tom and Doug Chemical Company were immediately brought back to the DuPont factory on the banks of the Brandy River in Delaware.

"Analyze the structure of this synthetic dye. ”

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

"Research!
